Must include:arc weldingLearn moreWhen do weld defects occur in a welding joint?Weld defects are more likely to occur at arc starts and stops. In starting the arc, the proper technique is to strike the arc at some point in the joint so that the metal is remelted. In completing a pass, the arc should not be abruptly extinguished leaving a large weld crater.See all results for this questionWhat kind of electrodes do you need for gas arc welding?This guide will help eliminate this variable as a concern in your welding and make it an asset.
