Tack Welding an SAE J429 Grade 5 Hex Bolt-1/2"
Tack Welding an SAE J429 Grade 5 Hex Bolt-1/2"
(OP)
Is it permissible to tack weld an SAE J429 Grade 5 1/2" Hex Bolt when the bolt is used to secure an OSHA Fall Protection Anchor? I am not comfortable permitting this, but I would like to see if anyone out there has any other information on the issue.
Thanks.

We have welded nuts on ASTM A193 B-7 studs (a similar material)for years with no problems. We used an AllState 275 or a 312 S/S rod. Though lately a lot have been welded with 7018.
I don’t have the current requirements for safety lines and anchor lines, but I understand some have came out. I would check. Even if its only a safety guideline follow it as it will soon be a requirements.
