Basic Knowledge of Sheet Metal Processing
We will introduce the basic knowledge of sheet metal processing.
"Welding processing" refers to the process of joining two or more metal parts. This page introduces "arc welding," one of the welding methods implemented at Tubota Technica. ○ Arc Welding An electrode is attached to the workpiece (referred to as the base material), and a large current is passed through it, generating an arc (discharge) between it and another electrode held in the other hand. The heat from this arc melts the metal to join them (only metals of the same type can be joined). A filler material, which is a metal, is added between the base materials being joined. This filler material is made of the same type of material as the base material and is in the form of a rod or wire. Depending on the specifications of the welding machine, the filler material may be fed manually by the operator or automatically supplied by the machine. The latter is referred to as semi-automatic welding. Arc welding is used in many welding points during the assembly of enclosures, starting with welding the edges of sheet metal at corners. At Tubota Technica, among the welding methods classified as arc welding, "CO2 welding" and "TIG welding" are mainly used. The "Basic Knowledge of Sheet Metal Processing - Welding Processing (3)" introduces the characteristics of these methods.
