The final part of this exercise in the PB (2F) position was a test on the influence of arc force...
Position & material:
PB (2F), tee joint between 10 mm thick mild steel, rolled flat bars with rolled edges.
Parameters:
All passes each side with 3.2 mm, 6013 (INE 46), DC positive, 125A, 50% arc force.
Remarks:
During welding, the arc was clearly 'stiffer', although the very fluid slag system in 6013 makes it harder to see clearly. The sections do suggest decent penetration, albeit the rolled corners of the oncoming plate are not fully consumed.
One conclusion I draw is that 6013 (at least the ones I've tried) can provide good penetration in a tee joint with "combined thickness"** of 30 mm, subject to adequate current, use of DCEP and a degree of arc force/dig.
** Per definition in EN 1011-2.
