Welding Problem A gas tungsten arc welding operation is used to create a fillet weld on both sides of a T-joint between two 1" thick medium carbon steel plates. The length of the T-joint is 36". The fillet weld as has a" legs. The welding operation will be carried out at a current 300 amps and a voltage of 20V. The welding process melts a volume of the parent material that is equal to 30% of the volume of the...
