Weld Deposit Weight, Filler, and Pass Count
Weld cross-section, deposit weight, filler purchased after deposition efficiency.
Example
You enter
- Joint type fillet
- Fillet leg (in, fillet mode) 0.3125
- Total weld length (in) 120
- Deposition efficiency (0-1) 0.9
- Max single-pass area (in2) 0.05
You get
- Weld cross-section 0.0488 in2
- Deposit weight 1.6617
- Filler purchased 1.85 lb
- Passes (estimate) 1 pass(es)

Details, formula, and sources
ScopeWeld 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 or tableFillet 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).
