Most of the time the weld specs will show you just what the PRE-HEAT temperature is. A method of checking the steel is with warmth pencils which melt at certain temperatures to point out when the proper warmth is reached. See CRACKING.

These welds are potent more than enough to carry and it truly is overkill to weld these joints reliable. When overzealous welders about weld, they are screwing up in several ways…

Flash Burn - That is a burn off in the radiation generated through the ULTRA VIOLET rays within the welding arc.

The cleaner the surface area, the higher your chance of a superb, pure, audio weld.

Slag – once the FLUX over a welding ROD melts it generates the SHEILDING Fuel to protect the weld, after which kinds a hardened protecting coating around the weld. This has to be chipped off and comprehensively cleaned, generally by brushing.
