Abstract
The paper deals with the possibility of producing equivalent joints on high-strength quenching steels by arc welding without preheating and heat treatment. Good prospects for application of austenitic-martensitic consumables in welding of high-strength steels without preheating and heat treatment with the level of weld metal strength of 1150−1200 MPa.
Keywords: welding, quenching steels, high-strength steels, multilayer welds, high-strength welds, welded joints, delayed fracture, process strength, cold cracks
