Looking at AWS D1.5M/D1.5:2010 to see if Table 5.1 can tell me if re-qualification would be required for a change in “Each manufacture’s brand and type of cored electrode”. What is meant by “manufacture’s brand”? I.e. if we change from using Lincoln brand to Esab brand, would that constitute as an essential variable or change that would require a separate PQR/WPS.
Thanks,
