Like any other high-carbon steel, all of the materials in question are difficult to weld. The only method of obtaining non-detachable joints of ball bearing steels that has found practical application is roller and contact spot welding.

Technical characteristics

The essence of the process is that the parts to be welded are heated until the metal softens, after which they are strongly pressed together. Heating is carried out by electric current, which passes through the current-carrying parts of the copper electrode or roller, moved along the area of weld formation. As the bearing steel softens, its ductility increases dramatically. If at this point the elements to be welded are squeezed with a force directed radially to the weld, a sufficiently strong joint is formed due to high-temperature diffusion.

Roller welding

Roller welding is considered more reliable than spot welding, because the formed seam will always be solid. Depending on the diameter of the electrode or the thickness of the roller, the connection zone will be a circle or a strip.

Welding technological regimes

Parameters that regulate the quality of the weld are considered:

1. The shape of the end face of the working electrode (it should be spherical or hemispherical;
2. The cyclic nature of the process - mainly the pulse mode with the number of pulses 10...15 is used (with increasing thickness of the workpieces their number increases);
3. Pressing pressure - it is determined by the thickness of details, but it should not be lower than 30 ... 35 kN;
4. The welding current strength - for maintenance of the proper speed of heating it shouldn't be lower than 30 ... 35 kA at preliminary warming up of the connection place, and 60 ... 70 kA - at welding proper.

Suitability of the equipment for contact/roller spot welding of bearing steels is the actual pressure applied, which should be not lower than the yield strength of the strongest of the materials being joined.
