A cold welding process that eliminates heat treatment of welds in hardenable steel or hardened steel, alloy steel, high alloy steel, high carbon forged steel, bi-metal union, manganese steel such as Hadfield steel, and so on, without hardening the deposited weld, wheraby also the transition area of the deposited weld is not hardened, thus preserving the mechanical and physical characteristics of the basic material, and maintaining the deposited weld fileable and machineable, by specific AWS-307, AWS-309, AWS-312 and AWS-8018 through 10018 electrodes. The temperature of the welded parts should never exceeed 100.degree.C during the welding process. This control of maximum temperature is obtained by welding a series of relatively short fillets instead of a single long fillet extending the length of the joint. The short fillets are followed by open spaces without a weld, and those open spaces are filled with weld fillets once the interrupted welding is completed for that weld pass.
