Peculiarities of spring steels welding

The steels under consideration contain not less than 0.5...0.75% carbon and are often alloyed with other elements - chrome, vanadium, silicon. The most commonly used mode of heat treatment of such steels (quenching at 850...880o C in oil and subsequent tempering at 400...640o C) gives the steels the required strength and ductility, but makes welding difficult. Therefore, welding of spring steels can be successful only if the welded parts are preheated (annealed). After welding, it is necessary to perform a final heat treatment of the joint. But it is recommended, if possible, to avoid welds in spring steel structures.

50KHGA

An exception is the spring steel of grade 50KhGA, which is welded without any restrictions, and welding is performed without heating and without subsequent heat treatment. At the same time in this case too the preliminary heating up to 200 ... 300°С and then annealing are carried out to obtain durable connection.

Welding modes of spring steel

If absolutely necessary, electric welding is used at the maximum current - not less than 200 A, forming the weld cathetus of the maximum possible size: this provides 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 pulsed arc micro-welding machine (for example, such as Orion PA230). Good results are obtained by welding with austenitic stainless steel electrodes: in this case the quality of the weld increases due to the higher solubility of hydrogen in the melt and the increasing consequent plasticity of the metal.
