Welding 12 Ga Material

[Deutero]

Fabricating a rectangular frame with light gage structural C-Sections, 45 degree mitered at corners.

AISC 9th TABLE J2.4 lists a minimum fillet for up "To 1/4 inclusive". Is an 1/8" all-around weld to much for 12 ga material?

Thank you ...

1/8" weld is acceptable with 12 GA material.

We do the same size welding here.

Instead of AWS D1.1, welds shall conform to AWS D1.3 for welding sheet steel.

Use the AISI code for cold-formed steel, not the AISC. Note also that because the corners of the studs have a radius, you will be using a flare bevel weld or a flare V weld depending on your connection.

12 ga. sheet metal (galvanized) is 0.1084 inches thick. If you are welding a fillet on the cut edge, you cannot use the full leg of a 1/8" fillet (reinforcement not allowed on fillet)

I have three questions.

1. Can any of the prequalified joints in D1.3 Sec 3 be used?

2. What will the welding symbol look like?

3. Will the welders be qualified per Sec 4 of D1.3?
