Simulation of strong variations of welding current against increased tensile strength of bolt and weld joints

Abstract

This study aims to analyze the simulation of welded current variations (100, 120, 140, and 160) Amperes at the combined combination of longitudinal, transverse, and combination (longitudinal-transverse) welds combined with the position of 4 square model bolts against an increase in plate tensile strength. The tensile testing process of welded and bolted combination joint specimens results in a ratio of tensile strength, loading, and elongation when the condition is proportional until the test specimen breaks. The results of tensile testing show that the simulation of variations in weld current given to the joint affects changes in loading, elongation, and tensile strength ratio. The position of the weld current of 140 Amperes at the combined welded direction (longitudinal-transverse) joint of the combination of 4 bolts of the square model has a maximum tensile strength of 347.222 MPa and a maximum strain of 58.758 % within 25.176 seconds. Results the combination join model is the best combination join of tensile test results. This research is expected to provide new insights into the use of current types and welding directions in welded and bolted combination connection systems in industries engaged in connection construction.
