When to use shielded metal arc welding ( SMAW )?
The shielded metal arc welding (SMAW / Stick) process generates an arc between a flux-coated consumable electrode and the work-piece. SMAW is well known for its versatility because it can be used in all welding positions, and in both production and repair welding situations.See all results for this questionWhat should the weave width be for arc welding?A rule of thumb is that the maximum weave width should be about three times the electrode core wire diameter. Once deposited, weld beads should preferably exhibit a slightly convex surface contour. Appropriate welding current is based on the diameter of the coated electrode.See all results for this questionWhat kind of equipment does arc welding use?Students will receive training in the use of the following equipment: Oxy-Acetylene Cutting, Shielded Metal Arc Welding (SMAW), Gas Metal Arc Welding (GMAW), Flux-Cored Arc Welding and Gas Tungsten Arc Welding (GTAW).See all results for this question
