Following on from Part 1 and comments by @Brad93 and @TechnicAl I repeated Part 1's exercise, with with a root run using 2.5 mm electrodes.
Position & material:
PB (2F), tee joint between 10 mm thick mild steel, rolled flat bars (hence rolled edges; see below).
Parameters:
Root pass each side with 2.5 mm, 6013 (INE 46), DC negative, 95A, zero arc force.
Remaining passes each side with 3.2 mm, 6013 (INE 46), DC negative, 125A, zero arc force. Passes were made on alternating basis, rather than building up complete weld on one side of the joint.
Remarks:
Very similar to the test in Part 1, and the root situation did not benefit from the smaller 2.5 mm electrode. Welder skill a likely factor. It would be interesting to see if and how some "dig" improves this aspect. One for a later test.
