– With a metal thickness of more than 1.5 mm, the pulsed arc electric welding with a melting electrode among inert gas is chosen.
In order not to depend on the thickness of the metal welded, use plasma welding. In everyday life it will be replaced by a manual argon -arc. A special installation is necessary for its implementation, which consists of a power source of various types with a control system, welding burner and gas cylinder.
