Overhead welding

(OP)
In the distant past, I read and recall using a fifty percent reduction for overhead welding.
Is this reduction used today? And if so where can I find it written? Thank you in advance.

RE: Overhead welding

No. Qualified overhead welding is the same as any other position weld, provided the welder is qualified for the position and deposits a proper weld profile without disqualifying defects.

RE: Overhead welding

Now, I might need a 50% increase in the TIME required to do an overhead weld .....

Never mind the pain and burns ... 8<)

Add also the time to get scaffolding, your fire watch, the equipment, etc into position. If you can avoid the overhead weld, do it.

RE: Overhead welding

AWS D1.1 lowers the maximum single pass fillet welds for overhead position as opposed to flat or horizontal. Welder also needs to be qualified to weld overhead position.
