This time, arguably at the opposite end of the penetration spectrum...
Position & material:
PB (2F), tee joint between 10 mm thick mild steel, rolled flat bars with rolled edges. Cut from same bar as used in Parts 1 and 2.
Parameters:
3 passes each side with 3.2 mm, 7016 (Filarc 56S), DC positive, 125A, zero arc force. Passes were made on alternating basis. The rods were not baked or prepared in any way, and have been stored in a rod tube, following opening of the original vacpac months ago.
Remarks:
A fairly lumpy profile on both sides , but markedly better penetration than observed with the 6013 (as you'd expect, hopefully!) The rolled edges of the oncoming plate at the root are almost completely consumed. More consistent penetration on the faces of the oncoming (vertical) plate, although penetration on the base plate is generally good. This is in the absence of any arc force/dig.
