The essence of welding is the formation of a joint during contact welding

In the manufacture of car parts, welding is an important technological process and many types of welding are used. Contact triple welding is the most effective, and in some cases, the only method in the manufacture of steel wheel rims ofpassenger cars. Because this type of welding is fast-acting, without any filler electrodes, without protective gases, does not require special preparation, suitable for mass production. On the rim preparation line, according to modern technology, from 0.01% to 0.05% of the rim can be rejected. Non-compliance of the material quality with the requirements and insufficient improvement of the welding technology leads to an increase in the level of defects up to 20%. This leads to excessive material consumption, an increase in the cost of production, and a decrease in the economic effect.
