Re: [MW:23146] Welding of Had field steel

Hi,

This material is highly prone to cracking when the base metal crosses certain temp.

Universally adopted method is to sink 3/4 the of base meat in a water trough & weld. While welding the base metal I.P. temp should be less than 100 deg. C.

This will definitely avoid cracking.

Check the grade of base metal & the same is available in SMAW consumables with all the manufacturers.

Main problem observed is start-stop point crack in specially SMAW. And PT is getting difficult to clear. Highly skilled welder is employed. So that possibility is ruled out of his ability and skill. Is this material prone to crack at start stop points only?
