Welding A325 hi-strength bolt to steel tube
Welding A325 hi-strength bolt to steel tube
(OP)
Hello,
I'm not familiar with the welding guidelines.
Is it possible to weld such a high strength material of A325 bolt with regular steel tubing?
Is there any consideration when we do this work, such as any strength limitation of the counter part material?
Thanks for your reponse,

In generally though, I would go with a Nelson fully threaded stud (h
or go with a hollow bolt.
......just really depends on what you want to use it for and what the loading condition is. I expect that the limit state would be your HSS.

AWS and RCSC would disagree.

Any benefit you have from using an A325 bolt will be negated when you weld it.
Agree that Nelson stud would be good; however, not every welding subcontractor has the capability; and technique is important. You can also buy the Nelson studs and weld them using conventional welding processes.

If ujinkim chooses to manually [SMAW, stick] weld Nelson studs, he should pry or knock out the 'load' from the tip of the stud. It is a small ball of aluminum added for deoxidizer for stud-welding, and is not needed for manual welding. Additionally, the aluminum will interfere with the flux mixture from the weld rod being used.
