Weld Strength Calculator fillet vs butt CalQlata

The thickness of all fillet welds is taken as the throat thickness in strength calculations.For volume calculations,the cross-sectional area of the weld is defined by the triangles in Fig 1 identified as; ' contributes to strength '.The excess material is not considered in the welding calculator's calculations as this will vary with the welder but will usually represent a pro-rata increase Weld Joint Preparation - WcWeldingImage A is an example of a one sided weld (fillet weld) of a single lap joint.Image B shows you a weld on both sides which will make it much stronger.Image C is what is called an offset lap joint.Your weld will be done in the natural seem made by the offset.It is usually a stronger weld than a single lap joint,but it can be more a more The Welding of Stainless SteelsTHE WELDING OF STAINLESS STEELS 2 1 General Information on Stainless Steels 1.3 Austenitic - Ferritic Duplex Stainless Steels Fe-Cr-Ni (Mo)-N The microstructure of duplex stainless steels consists of a mixture of austenite and ferrite.They exhibit characteristics of both phases with higher strength and ductility.Nitrogen is added to provide
