Features of welding

The considered steels contain not less than 0.5… 0.75% carbon, and are doped with other elements — chromium, vanadium, silicon. The most frequently used mode of heat treatment of such steels (quenching from 850… 880 ° C in oil and subsequent tempering at 400… 640 ° C) gives the steel the necessary strength and ductility parameters, but makes welding difficult. Therefore, before welding, preheating (annealing) of the welded parts is necessary. After completion, it is necessary to re-heat the joint. However, whenever possible, avoid welds in structures made of such steels.

50ХГА

An exception is the spring-spring mark 50ХГА, which is welded without restrictions, while welding is performed without heating, and without subsequent heat treatment. At the same time, in this case, preheating to 200… 300 ° C is performed to obtain a durable bond, and then annealing is performed.

Welding modes

If absolutely necessary, use electric welding at the maximum current — not lower than 200 A, forming a cutout of the maximum possible size of the seam: this ensures a satisfactory heating of the metal. In order to increase the efficiency of the welding process and reduce the consumption of welding electrodes, it is recommended to use a pulsed arc welding machine (for example, type Orion PA230). Good results are obtained by welding using electrodes made of austenitic stainless steel: in this case, the quality of welding increases due to the increased solubility of hydrogen in the melt and the increased plasticity of the metal due to this.
