The head is formed by forging or machining. The bolt is admitted through holes in the parts, which are to be fastened. The projected thread end of the bolt admits a corresponding nut from the other side. Tightening the bolt by turning gives necessary clamping grip to hold the parts together.\r\n\r\nBolts and nuts of various shapes are used for different purpose but the hexagonal head and square head are very common. Although, the square shape provides better spanner grip than the hexagon, but needs one fourth of a turn to bring it into the same position for inserting spanner again, whereas a hexagon need only one sixth of a turn and hence provided.\r\n\r\nThe sharp corners on the external flat end faces of bolt heads and nuts are chamfered conically at 30\u1d3c to ensure safety of the user. To facilitate early insertion of the nut over the bolt, the threaded holes in the nut are countersunk.\r\n\r\n Three dimensions are usually sufficient for simplified representation of a bolt\r\n\r\n \tThe bolt shank diameter (d)\r\n \tThe bolt length (l)\r\n \tThe length of a threaded portion of the shank (b)\r\n\r\nRead more :\u00a0What is riveted joints- Forms Of Rivets Head Shapes\r\n\r\n EMPIRICAL PORTIONS OF HEXAGON AND SQUARE HEAD BOLT &amp; NUT\r\nDETAIL PROPORTION:\r\n\r\n \tNominal diameter d=size of bolt or nut,mm\r\n \tWidth across flats s=1.5d+3mm\r\n \tWidth across corners e=2d\r\n \tThickness of bolt head k=0.8d\r\n \tThickness of nut n=0.9d\r\n \tRoot diameter d1=d-(2*depth of thread)\r\n \tLength of the bolt l=as specified\r\n \tThread length b=2d+6mm (for l&lt;150mm) =2d+12mm (for l&gt;150mm)\r\n \tChamfer of bolt end Z=depth of thread*45(degree) (or) =0.1d\r\n \tChamfer angle of bolt head &amp; nut 30 (degree)\r\n\r\n types of bolts\r\n Special Types of Bolts :\r\nIn practice various types of bolts than the hexagon and square head bolts are used in where the bolt head cannot be held by the spanner when the nut is turned on or off the bolt. The rotation of the bolt prevented by a stop pin or a snug or a square neck provided below the head.\r\n\r\n\u00a0Cylindrical or Cheese Headed Bolt:\r\nThe head of this type of bolt is of cup shape and the rotation of the bolt head is prevented by a stop pin. The stop pin may be driven into the shank with its axis perpendicular to the axis of the bolt. The stop pin may also be driven into the head adjacent to the shank with its axis parallel to the axis of the bolt. These types of bolt heads are used in the big ends of the connecting rods, eccentrics, cross heads etc...\r\n\r\n\u00a0Cup Or Round Headed Bolt:\r\nTwo types of cup head bolts are available. In one type, a snug is provided which prevents the rotation of bolt head. The other type, a square neck is provided which will fit into the square hole provided in the bearing surface and thus prevents the rotation of the bolt head.\r\n\r\n\u00a0Counter Sunk Head Bolt:\r\nThe counter sunk head bolts are used when the bolt head must not project and foul with surfaces. The counter sunk bolt is provided with a stop pin of square cross section integral with the head. The other type of counter sunk bolt is provided with the square neck below the head. This type of bolt is also called as \u201ccoach bolt\u201d.\r\n\r\nHead Bolt:\r\nThe head of this bolt is like letter \u201ei\u201f. These bolts are used in bearing housing and in glands packing. These bolts are used in setting work on machine tool tables. The i head of the bolt can slide, to the required position through the i slots cut on the m\/c table.\r\n\r\nEye Bolt:\r\nThe head of the bolt is in the form of circular form of rectangular cross section. It is generally used in the inspection covers, lids etc..., Which have to be opened and closed frequently.\r\n\r\nLifting Eye Bolt:\r\nThe lifting eye bolt, having a circular ring of circular cross section as head. A flat circular portion, integral with a head is also provided. This type of bolt is used for lifting a heavy machine such as motors, pumps, turbine, electrical generators etc., This bolt is screwed in a threaded hole provided for this purpose , on the top of the machine directly above the centre of gravity so that while lifting the machine does not change from its usual working position.\r\n\r\nHook Bolt:\r\nThe hook bolt has its head comprising of a square neck and projection. The shank of the bolt passes through a hole in one of the fastening pieces and the other piece comes under the bolt head and is supported by it.","headline":"What is Bolt Fastener &#8211; types of Bolts","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2019-02-26","mainEntityOfPage":"False","dateModified":"February 22, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2019\/02\/types-of-bolts-300x147.jpg","height":147,"width":300},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <article class="article-card horizontal "> <a href="//www.gunkrazy.com/what-is-riveted-joints-forms-of-rivets-head-shapes/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2019/02/shape-of-rivet-300x215.jpg')"></div><span class="sr-only">link to What is riveted joints &#8211; Forms Of Rivets Head Shapes</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/what-is-riveted-joints-forms-of-rivets-head-shapes/">What is riveted joints &#8211; Forms Of Rivets Head Shapes</a></p></header><div class="excerpt"><p>What is riveted joints - Forms Of Rivets Head Shapes

Riveted joints are extensively used in structural works such as bridges and roof trusses and in the construction of pressure vessels such as storage tanks, boilers, etc. Although welded joints are best suited to several of these applications than the riveted joints, however, riveted joints are ideal in cases where the joints will be subjected to pronounced vibrating loads. Riveted joints are also used when a non-metallic plate and a metallic plate are to be connected together. They are also used when the joints are not expected to be heated while joining as in welding, which may cause warping and tempering of the finished surfaces of the joints.\r\nThe disadvantage of riveted joints are: (i) more metal is removed while making of the holes, which weakens the working cross sections along the line of the rivet holes, and (ii) weight of the rivets increases the weight of the riveted members.\r\n\r\nRead More :\u00a0Types Of Riveted Joints and their Applications-Machine Design\r\n\r\n\u00a0DIFFERENCES BETWEEN A BOLT AND A RIVET\r\nAs a fastener, a riveted resembles a bolt, but differs from it in the shape and the application as well. Although the shape of a rivet is similar to that of a bolt, unlike the bolts, it is used as a permanent fastener to withstand shear forces acting perpendicular to its axis, whereas a bolt is used as a temporary fastener to withstand axial tensile forces.\r\n\r\nRIVET\r\nA rivet is a round rod made either from mild steel or non-ferrous materials such as, copper, aluminium, etc., with a head is, and formed at one end during its manufacture and its tail end being slightly tapered. The length of the shank of the rivet must be sufficient enough to accommodate the connection plates and provide enough material for forming a head at its shank end. In general, the shank of the rivet will be equal to sum of the thickness of the connecting plates plus 1.5 to 1.7 times the diameter of the rivet.\r\n\r\nIf, l = length of the shank of the rivet\r\nd = diameter of rivet\r\nt = thickness of each of the connecting plates\r\nthen, l = \u03a3t + (1.5 to 1.7)d\r\n\r\nFORMS AND PROPORTIONS OF RIVET HEADS\r\n\r\nVarious types of rivet heads for the use in general engineering work and boiler work as recommended by the Bureau of Indian Standards. The different proportions of these rivet heads are given in terms of the nominal diameter d of the rivet. The rivet head to be used for general purposes for diameter below 12 mm are specified in the Indian Standard code IS:2155-1962 and for diameters between 12 and 48 mm are specified in the Indian\r\nStandard code IS:1929-1961. The rivet heads to be used for boiler work are specified in the Indian Standard code IS: 1928-1961.

Both ferrous (steel, cast iron) and Non-ferrous metals (like brass copper and alloy) can be joined by welding.\r\n\r\nThe welding is cheaper, stronger, easier and faster than riveting. The various types of welding process are\r\na. Gas welding\r\nb. Arc welding\r\ni. Metal Arc Welding (MAW)\r\nii. Gas metal Arc Welding (GMAW)\r\niii. Submerged Arc Welding (SAW)\r\niv. Tungsten Inert Gas Welding (TIG)\r\nv. Metal Inert Gas Welding (MIG)\r\nc. Forge Welding\r\nd. Resistance Welding\r\ne. Thermit Welding\r\nf. High Energy Welding\r\n\r\nThe welded joints are broadly classified into\r\n\r\na. Butt joint b. Lap joint c. Corner or Fillet joint d. Tee joint e. Edge joint\r\n\r\n SYMBOLIC REPRESENTATION OF WELD\r\nThe standard welding symbol is given below.\r\n\r\n\u00a0Arrow Line and reference Line\r\n\r\nThe position of the arrow line with respect to the weld is of no special significance. The side of the joint on which the arrow line is drawn is called \u201carrow side\u201d. The side of the joint remote to the arrow line is called \u201cother side\u201d. The reference line has significance on the weld side. If the weld symbol is placed BELOW the reference line, the welding should be done in the \u201cARROW SIDE\u201d. If the weld symbol is placed ABOVE the reference line, the welding should be done in the \u201cOTHER SIDE\u201d. If the weld symbol is placed both ABOVE and BELOW the reference line, the welding should be done in both the \u201cARROW AND OTHER SIDES\u201d\u00a0\r\n\r\n welding_symbol_description\u00a0 \u00a0 Image SOURCE :Welding universe\u00a0\r\n\r\nBasic Weld Symbol\r\n\r\nThe basic symbols recommended by Bureau of Indian Standards (BIS) for specifies the type of weld are shown in the fig\r\n\r\n weld symbol\r\n\r\nSize of weld\r\nThe size of the weld is height of the isosceles triangle in the case of fillet welds. In other cases, the size will be the minimum distance from the surface of the paert of the bottom of penetration.\r\n\r\nFinish and contour symbol\r\nThe contour symbols are\r\na. Flat (flush)\r\nb. Convex\r\nc. Concave\r\nFinishing welds other than cleaning shall be indicated by finish symbols.\r\nChipping \u2013 C, Grinding \u2013 G, Machining \u2013 M \r\n\r\n finish counter symbol\r\n\r\n Welded and unwelded length\r\nLength of weld means it is the length to be welded once, after that pitch equal to unwelded length is not welded and this process is continued for the whole length of the side.\r\n\r\nWeld all round\r\nIf the weld should be made all round the joint, a circle should be placed at the point connecting the arrow and the reference line.\r\n\r\nSite weld\r\nWhen some of the welds (the welded structures) are required to be made on site during erection. They should be designed by a filled in circle at the point connecting the arrow and the reference line.","headline":"Basic Of Welding Symbol &#8211; Symbolic Representation of Welding Symbol","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2019-02-26","mainEntityOfPage":"False","dateModified":"February 22, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2019\/02\/welding_symbol_description-300x190.jpg","height":190,"width":300},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <article class="article-card horizontal "> <a href="//www.gunkrazy.com/unigraphics-ug-nx-interview-questions-and-answers/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2019/02/nx-interview-question-and-answers-300x161.jpg')"></div><span class="sr-only">link to Unigraphics (UG) NX Interview Questions and Answers</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/unigraphics-ug-nx-interview-questions-and-answers/">Unigraphics (UG) NX Interview Questions and Answers</a></p></header><div class="excerpt"><p>Unigraphics (UG) NX Interview Questions and Answers

Basic of Catia - 2. Part Design - 3. Assembly - 4. Surfacing\u00a0\r\n\r\n1) What do you mean by Gateway Application in UG?\r\nUnigraphics functions are divided into applications of common capabilities, such as Modeling , NX Sheet Metal, Shape Studio, Drafting, Manufacturing, Assemblies etc. When you open Unigraphics, you are in the Gateway application because this application is a prerequisite to all other application.\r\n\r\n2) What is Master Model Concept?\r\nThe same model is used from conceptual design to the Drafting, Assembly, Analysis and Manufacturing. The idea of a virtual assembly taken to its logical conclusion leads to Master Model paradigm. If you change any thing in Master Model, it will reflect in all other applications.\r\n\r\n3) What do you mean by Team Center?\r\nIt is a PDM (Product Data Management) software which helps the organisation effectively control the design, development, analysis, manufacturing through out the product of life cycle.\r\n\r\n4) How to convert a file created in mm to inches (conversion of units) in UG?\r\nWe can convert a file created in mm to inches by using UG command prompt.\r\nug_convert_part (space) -in (space) 1234.prt\r\nNote: Save your file where command prompt showing location; Example:- C:\/users\/username\r\n\r\n5) What is meant by UDF?\r\nUser defined feature is used to create the objects of different sizes in a single file. We can create our own form features that automate commonly used design elements. You can create and add the user defined features (UDFs) to target solids. You can define the shape and function of features, and create hierarchical libraries of features that are tailored to our need.\r\n\r\n6) What is Promote body?\r\nWhen you have an assembly that is work part, this option lets you promote a body from a loaded assembly component to the level of the assembly. The promote body remains associative to the original body, which is referred to as the base body.\r\nOnce you have promote a body, you can perform operations on it, such as adding features, performing Boolean operations between it and other bodies, and so on. The effects of these operations are only visible at the level of the assembly work part in which the promote was created, and in any other assembly that references that part.\r\n\r\n7) What is Wave Link Geometry?\r\nThis option create an associate copy of composite curve, sketch, datum, point, face, body, mirror body of part file in assembly file. Once you have a wave linked boy you can perform operations on\u00a0 it. (Example: In Machining model you can add wave link of Casting model and perform the machining operations)\r\n\r\n8) What is Extract Body?\r\nThis option create an associate copy of an entire body in part file. Features can then be added to Extract Body feature without appearing on the original body. You can also decide whether you want he Extract Body feature to update when the original body is changed.\r\n\r\n9) What are Part families?\r\nThis option let you create a family of parts by creating a template part. You can use the Unigraphics spread sheet (via the Create button on the Part Families dialog) to create a table describing the various part family members.\r\n\r\n10) What do you mean by Expressions?\r\nExpressions are mathematical or conditional equations used to control the parameters of a model. With expressions, you can easily apply major edits to a model. By changing the expressions that control a specific parameter, you can re-size or re-position features of a solid model\r\nThree types of Expressions are there\r\n1. Airthmatic Expressions\r\n2. Conditional Expressions\r\n3. Geometric Expressions\r\n\r\nnx interview question and answers\r\n\r\n11) What is Direct Modeling or Synchronous Modeling?\r\nDirect modeling techniques represents extended capabilities for some of the more basic Unigraphics functions. Among these are face oriented operations, constraint based methods, blend regeneration and independence of feature history. You can use Direct modeling functions on models that have been imported from other CAD systems and are non-parametric.\r\n\r\n12) What is the limit for Undo?\r\nwe can use Undo for 222 times or until up to last time saved.\r\n\r\n13) How many colors in are there in UG?\r\nThere are 216 colors in UG.\r\n\r\n14) How many Layers are there in UG?\r\nThere are 256 Layers in UG.\r\n\r\n15) What are Grips? What are there uses?\r\nGrip programs can be executed as button action by specifying grip executable file names. The uses of Grip are\r\n4. Simplify Repetitive Operations\r\n5. Standardized Results\r\n\r\n16) What do you meant by Weight Management?\r\nThe Weight management option allow us to calculate and control the weight and other mass properties of parts, components and assemblies based on the solid bodies they contain.\r\n\r\n17) What do you mean by Knowledge Fusion?\r\nThe Unigraphics NX Knowledge Fusion application provides a graphical user interface that allows us apply engineering knowledge driven rules and design intent to geometric models and assemblies in Unigraphics.\r\n\r\n19) What is Parasolid?\r\nPara solid is form of translator which is used to open the higher version Unigraphics part files to in lower version of Unigraphics. For example we can open the NX7.5 version part files in NX4.\r\n\r\n20) How can we create a mosquito coil?\r\nWe can create a mosquito coil by first creating an inclined helix curve and then projecting it to the bottom plane. Then we need to use the sweep along guide command.\r\n\r\n21) What is Datum Plane? Why it is used?\r\nDatum Plane is reference feature that can be used to as construction tool in building the model.\r\n\r\n22) What is Datum Axis?\r\nDatum Axis, which is a reference object you can use to create other objects, such as Datum planes, revolved features, and extruded bodies. Datum Axis can be either relative or fixed.\r\n\r\n23) What is constraint?\r\nConstraints limit structural movement and represent mounts and supports. Constraints can be applied to faces or edges. (Restricting the degree of freedom)\r\n\r\n24) How many types of constraints are there?\r\nThere are two types of constraints.\r\n1) Geometrical constraints 2) Dimension constraints\r\n\r\n25) What is sketching plane?\r\nTo create a sketch, you must associate the Sketch feature to a planar object. We can select a face or Datum plane. This plane is know as sketching plane.\r\n\r\nMore Unigraphics general interview questions:\r\n1. Explain types of Modeling?\r\n2.
