Welding of bearing steel
Buy in stock ball bearing steel of different brands at factory price offered by the company Electrocentury-steel. Vendor provided prompt delivery of metal in any item specified by the customer.
The principle of welding
Like any other high carbon steel, all the materials are difficult to weld. The only way of obtaining permanent joints of the ball-bearing steels, which have found practical application is resistance spot welding.
The essence of the process is that the welded part is heated to a state of softening the metal, then heavily compress between them. Heating is performed by electric current that passes through current carrying parts of copper electrode or roller that is moved along the formation zone of the weld.
With the softening of bearing steel is its ductility increases sharply. If at this point you are squeeze welded elements a force directed radially relative to the weld, due to high temperature diffusion formed quite a strong connection.
Depending on the electrode diameter or thickness of the clip connection area will be in the form of a circle or stripes. Roller spot welding is safer because of the emerging seam is always solid.
The company Electrocentury-steel offers to buy at cost-effective price the manufacturer of a variety of rolled ball-bearing steel. The supplier provides timely delivery of products to any place specified by the consumer.
Technological modes of welding
Parameters governing the quality of the weld, are:
The shape of the end face of the working electrode (it should be spherical or hemispherical;
A cyclical process is used primarily in pulse mode the number of impulses 10…15 (with increasing thickness of the workpieces, their number increased);
The contact pressure is determined by the thickness of parts, but must be below 30…35 kN;
Amperage — to ensure proper speed of heating it should not be below 30…35 kA at pre-heating the junction, and 60…70 kA — when actually welding.
Suitability of equipment to perform the pin/roller spot welding of bearing steels is the actual pressure which should be below the yield strength of the durable of the joined materials.
