Maxium Puddle Weld Plate Thickness

Maxium Puddle Weld Plate Thickness

Maxium Puddle Weld Plate Thickness

(OP)
What is the maxium thickness of steel PL that can be effectively attached by puddle welding?

In my situation I have a 12 GA steel plate being attached to the flanges of multiple W beams.

Can this connection be made by x" dia  puddle welds at x" o.c.?

Thanks!

RE: Maxium Puddle Weld Plate Thickness

I don't see why not.

RE: Maxium Puddle Weld Plate Thickness

If you mean by puddle welding using an oxyfuel gas welding process, the answer is yes. For 12 gage steel sheet, it should not be a problem.

However, why don't you use the GMAW or MIG process for attaching the 12 gage steel sheet? It is faster, cleaner and would probably cost less regarding consumables.

RE: Maxium Puddle Weld Plate Thickness

If you are using AWS D1.3, max thickness is 0.15 in, so 12 GA is in compliance...ref: Sec 1.5.4

Make sure the WPS has been qualified by testing (Sec 4.2---Engineer's approval), as this joint does not conform to prequalified joints shown in Sec 3--Prequalification of WPSs.

D1.3 Sec 1.3.1 covers approved welding processes...Table 4.1, item 4.4 covers test assembly used for WPS qualification....and Table 4.2, item 4.4 deals with welder qualification requirements. The special inspector must verify WPS and welder's certs in the field.
