What kind of electrodes are used in arc welding?

Guides for the various welding processes follow. For shielded metal arc welding (SMAW), the flux covered electrode ECuNi is used with direct current electrode positive (reverse polarity). If the arc length is kept short, the weld pool can be controlled in all positions with a 3/32- or 1/8-in. (2.4- or 3.2-mm) diameter electrodes.See all results for this questionWhat is the benefit of grounding an arc welding machine?Grounding the workpiece has similar benefit to grounding the welding machine enclosure. When the workpiece is grounded, it is at the same potential as other grounded objects in the area. In the event of insulation failure in the arc welding machine or other equipment, the voltage between the workpiece and ground will be limited.See all results for this questionWelding and Valves Go Hand in Hand - Valve MagazineWelding and valves officially became joined at the hip with the perfection of the arc-welding process in the late 1920s. Up until then, every component in a valve was made of solid, homogeneous material, and all the end connections were either threaded or flanged.
