How do you estimate the amount of welding electrode/wire for a job?
How do you estimate the amount of welding electrode/wire for a job?
(OP)
Is there a rule of thumb for estimating the amount of welding wire or welding electrode that is needed for any specific job?
For example: If I have a 1/2" fillet weld 20" long, how much welding electrode do I need to buy to complete the job?
I would like a rule of thumb for both shielded arc and tig.
Is there a difference in the estimate for different materials?
Thank you in advance for your help.

RE: How do you estimate the amount of welding electrode/wire for a job?
for SMAW, stick welding multiple this value by 1.3 to 1.4 to account for stub losses.
for GTAW (TIG) welding use a factor of 1.1 (10% extra)
1/2" fillet 20" long
((1/2inch*0.707)^2)*20inch*1.3 *490lb/ft3*1ft3/1728 in3=
-------------------
2
= 0.35 lbs (SMAW 1/2" fillet @ 20")
Hope this helps, Rich
