Welded Joints VS Bolted Joints -

Bolt and nut connections may not serve the same strength of the parts manufactured as one united piece like well welded joints,but since the bolting process is more routine and requires less qualification,bolted connections provide acceptable strength ,durability and safety,something that can be hardly said about welded connections unless Weld StrengthNov 04,2014 ArticleDesign strengths of welded connections#0183;Section 5.5.Strength Limit State.Last Revised 11/04/2014 The only strength based limit states associate with a properly designed (i.e.meets all the applicable limitations) welds are the strength of the weld and the strength of the base metal that the weld is attached to.Weld Strength Calculation Example for Design of Fillet Oct 18,2012 ArticleDesign strengths of welded connections#0183;Problem statement Look at the design of the welded connection below,its a cantilever kind of structural joint where the fillet welds are subjected to the torque developed due to the load F.Calculate the fillet weld size required for the application.Fillet Weld Strength Design Calculation in Torsion Example .Given,F= 20000 N.X = 200 mm.Y

How to Determine the Strength of a Transverse Fillet Weld

F is the force the weld can handle,in other words,the strength of the weld in lbf.A is the effective area of the weld.The effective area of a weld is calculated by multiplying the length of the weld times the throat of the weld.For design purposes we use the theoretical throat as shown below.In the above diagram,is the fillet weld leg size.How to Determine the Shear Strength of a Fillet Weld The forces are pulling the members being joined in opposite directions,which places the welds under shear.When a weld is in shear we cannot longer use the tensile strength of the filler metal to determine the strength of the weld.Instead,the tensile strength is reduced by a factor in order to assure safety.How to Design Fillet Weld connection for Steel Trusses In modern construction,the commonest methods of connecting steel members are by bolting and welding.Eurocode 3 identifies different types of welding such as; fillet welding butt welding plug welding,and flare groove welds.Fillet welds are generally used for connecting parts where the fusion faces form an angle of between 60 ArticleDesign strengths of welded connections#176; and 120 ArticleDesign strengths of welded connections#176;.Although []

Flexural Strength Prediction of Welded Flange Plate

The present study was aimed to investigate the strength and ductility of welded flange plate (WFP) connections.Using the FE method,52 WFP connections with different beam overall depths and beam flanges/web slenderness ratios were analyzed.Fragility curves indicated that,for a WFP connection which is designed based on the seismic codes,its strength is of more concern than its ductility.Fillet Weld Strength Calculation Example for Welded Oct 07,2012 ArticleDesign strengths of welded connections#0183;Weld leg length (L) need to be find out using the eq.7 as L=1.414*t = 1.414*0.331 = 0.468 mm .So,from the fillet weld size calculation example we found that the required minimum weld leg length to withstand the weld force is to be 0.468 mm,we will take the 3mm as the weld size for this example problem.Fillet Weld Strength Calculation Example for Welded Oct 07,2012 ArticleDesign strengths of welded connections#0183;Weld leg length (L) need to be find out using the eq.7 as L=1.414*t = 1.414*0.331 = 0.468 mm .So,from the fillet weld size calculation example we found that the required minimum weld leg length to withstand the weld force is to be 0.468 mm,we will take the 3mm as the weld size for this example problem.
