Abstract

The program makes the welding process more accurate with welding parameters used, more time saving, and lowcost operation, and it can also improve the welding operator’s metallurgy knowledge. Good weldment depends on the skill and experience of the operator’s. This program includes the chemical elements content of the steel, the diameter of the electrode; electric current; electric voltage, welding speed; metal thickness will be welded and heat input. Visual Basic package program used to create the program. The study aims to create the program for determining the width of heat affected zone based on welding parameters. This research may simulate the heat-affected zone dimension based on the heat input temperature from arc welding.
