Description and precautions for welding low alloy steels

Welding-steel low carbon and low alloy Materials and

Carbon and low alloy steels can be joined under wide ranges of Welding-steel conditions.Medium carbon and alloy steels can be friction welded but with more strictly controlled parameters ,because of their hardening properties,and then only for non stressed members.Welding of Dissimilar Metals : Total Materia ArticleWelding Nickel-Base Alloys to Steels Nickel-base alloys such as Monel and Inconel can be successfully welded to low-alloy steel by using the Monel analysis of filler material when using any of the arc welding processes.In the case of Inconel to mild or low-alloy steel the Inconel base electrode would be used.Welding Precautions for T-1 Steels - lincolnelectricWhat precautions should I take when welding T-1 steels? T-1 is a quenched and tempered steel.Welding quenched and tempered steels may be difficult due its high strength and hardenability.The base steel around the weld is rapidly being heated and cooled during welding,resulting in a heat affected zone (HAZ) with high hardness.
