Hi Guys,
I am not sure I am in a right forum or not but, does anybody know what type of welding I have to use for ASTM A242.
Thanks a million

RE: Weld type for ASTM A242??

A 242 is a specification for high strength low alloy steel shapes. This material can be welded using most common arc welding processes; SMAW, FCAW, GTAW, SAW. What else do you need to know?

Metengr,
Thanks for your response!considering that it's atmospheric corrosion-resistant, is there a particular electrod required?  

RE: Weld type for ASTM A242??

Use E8018W, E8018-B2 or E7018-B2L type filler to match atmospheric corrosion resistance.

RE: Weld type for ASTM A242??

Those B types are no good for fatigue applications; they're not Charpy-tested.  What's the application?

Basically, what you want is that which is listed in AWS D1.1 Table 3.3 or D1.5 Table 4.3.

Thank you all so much.  

RE: Weld type for ASTM A242??


"On single pass welds, mild steel electrodes are commonly used. There is usually enough pickup from the base metal to obtain a good color match.

On multiple pass welds, low-alloy electrodes are commonly used to obtain a good color match and similar corrosion resistance. The electrodes commonly specified include those with the suffixes -C1, -C2, and -C3. "
