Low Alloy Electrodes
Low Alloy Electrodes
(OP)
Back ground
Carbon Steel component (Say API 5L x 65 Pipe welded pipe, thickness 15mm) is being welded with Electrodes and the electrodes are classified under Low alloy electrodes (As per AWS/ ASME Sec II C).
I know that (On general situation) that when a low alloy base metal is welded, PWHT is called for.
What if CS material is welded with Low alloy electrode. Does it call for PWHT.

When welding X-65 with low hydrogen electrodes similar to E8018-C3 or E9018M Nickel/Chrome/Mo type alloy electrodes, preheat is normally not required and PWHT is normally not performed.
