What Is Heat Input, and How Does It Affect the Quality of Welds?

Heat input can be referred to as “the electrical energy supplied by the welding arc to the workpiece.” In practice, however, heat input can approximately - if the arc efficiency is not taken into consideration - be characterized as the ratio of the arc power supplied to the electrode to the arc travel speed, asContinue reading “What Is Heat Input, and How Does It Affect the Quality of Welds?”
