    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. This information applies only to the selection and preparation of electrodes for Gas Tungsten Arc Welding (GTAW), also known as Tungsten Inert Gas (TIG) welding and Plasma Arc Welding (PAW).See all results for this question

    What are the subtypes of gas arc welding?

    Gas metal arc welding (GMAW), sometimes referred to by its subtypes metal inert gas (MIG) welding or metal active gas (MAG) welding, is a semi-automatic or automatic arc welding process in which a continuous and consumable wire electrode and a shielding gas are fed through a welding gun (mig torch).Also known as a CO2 welder.See all results for this questionWelding of stainless steel pipe fittings - Knowledge s20200 connection annealed Argon arc weldingStainless steel pipe fittings (Stainless steel pipe fittings) are stainless steel pipes that are inserted into the socket part of the pipe and then welded along the edge of the pipe to make argon arc welding. It is the most reliable connection among all connection methods.
