Tensile test analysis for steel welding connections as a basis for compiling welding procedure specification (WPS)

Abstract

Welding is the train manufacturing industry's most widely used method of joining metal plates. The welding method and the qualification of the weld results can be ascertained using the WPS document. The construction of WPS begins with setting up standards that will obtain the most appropriate welding procedures, then determining the type of material strength test to ensure the quality of the welds. This research was conducted to determine whether the S355 J2 steel can withstand the stress of the load before it is deformed by the welding procedure that has been determined. Tensile tests were carried out on welded S355 J2 steel. The tensile test results obtained a higher value than the standard material that is not welded. Therefore, it can be ensured that the welding procedure used is correct. This is caused by several factors, including the type of welding according to the material, the use of the type of electrode, the making of the joint design, and the correct welding parameters.
