how many weld passes does it take?
how many weld passes does it take?
(OP)
Hi,
Does anyone know of a table that would tell me how many passes it would take to get a weld of various sizes?
I.e. how many passes for a 1/2" weld,.. and how many passes for a 5/8" weld.. etc...
I'm an engineer and I spec welds all the time, but havent (until now), given much thought to the poor sod doing the welds.
Thanks

Larger welds would be proportionate to the weld volume which is proportionate to the leg length squared. so by this theory 3/8" is two/three pass, 1/2" is a 4 pass e.t.c.
If the fillet weld ends up larger than 1/2" then I would normally use a butt weld instead as it is usually cheaper.

Stick welding........... 2 lb/hr
Mig welding............. 5 lb/hr
Submerged Arc welding... 10 lb/hr
The deposition rate for submerged arc welding takes into account the increased setup time to use that method. Those are rates for skilled welders.

For example (from d1.1:2002....it was handy)....maximum single pass fillet in flat position for smaw is 3/8 in. For gmaw/fcaw it is 1/2 in. For the overhead position, this goes down to 5/16 in for both.
Maximum fill passes are 3/16 in for smaw and 1/4 in for gmaw/fcaw.
These are for prequalified WPS.
