Weld Deposit Weight, Filler, and Pass Count

Weld cross-section, deposit weight, filler purchased after deposition efficiency, and the pass count for a fillet (by leg) or groove (by area) weld from first-principles joint geometry and steel density (0.2836 lb/in3). The WPS and the shop's measured deposition efficiency govern.

Formula and source

Fillet area = leg2 / 2 (equal-leg) or user-entered groove area; deposit volume = area x length; deposit weight = volume x 0.2836 lb/in3; filler purchased = deposit / deposition efficiency; passes = ceil(area / max single-pass area).

Weld deposit weight and filler consumed - first-principles joint geometry and steel density (0.2836 lb/in3, matching metal-weight), by name; public domain.
