Craftsman Shielded Metal Arc Welding case studies
Craftsman Shielded Metal Arc Welding · Put your knowledge to work in context.
Craftsman-level Shielded Metal Arc Welding (SMAW) certification is a trade credential that demonstrates a welder can set up a stick welding station, run sound welds in the flat, horizontal, vertical and overhead positions, and finish a joint that meets a written acceptance standard with little supervision. It is aimed at working welders, maintenance technicians, fabricators and career-changers who already have basic arc time and want their skill judged against a recognised benchmark rather than an employer's in-house opinion. The Craftsman Shielded Metal Arc Welding case studies are 5 cases and about 3,853 words.
