What is the standard of sheet metal processing?

What is the standard of sheet metal industry? General accident maintenance can be operated independently, and sheet metal workers refer to people who have long time and experience in sheet metal technology. No matter the level or salary, it is one level lower than the master and one level higher than the apprentice. Workers who do sheet metal work are mainly divided into four grades: master, intermediate worker, apprentice and handyman.

Sheet metal, a processing technology, has not been fully defined. According to a definition in foreign professional journals, it can be defined as: sheet metal is a comprehensive cold working process for metal plates (usually less than 6mm), including shearing, punching/cutting/compounding, folding, riveting, splicing and forming (such as automobile body). Its remarkable feature is that the same parts have the same thickness.

Generally speaking, the basic equipment of sheet metal processing includes shearing machine, CNC punch, laser, plasma, water jet cutting machine, bending machine, uncoiler, straightener, deburring machine, spot welding machine and other auxiliary equipment.

Modern sheet metal technology includes fiber winding, laser cutting, rework, metal bonding, metal stretching, plasma cutting, precision welding, rolling forming, sheet metal bending forming, die forging, water jet cutting, precision welding and so on.
