Andrew's company is seeing welding procedures for open root 7016. Before tackling an open root pipe with 7016, some might benefit from a few practice plates. Fitup, featheriing tack welds, arc length, rod angle, are discussed.
Welding Overhead with 5/32" 7018 is a bit more challenging than with smaller electrodes but the same fundamentals apply for the most part.
Tight arc length, rod angle, and restarts are demonstrated with instructive arc shots and body positioning.
6013 stick welding tips for anyone in welding school trying to move on to 6010 and 7018...or who wants to build something and only has an AC buzz box welder.
