Description

Technical Field

[0001] The invention relates to the technical field of cold-rolled plate welding, in particular to a cold-rolled plate forming welding system. Background Art

[0002] Cold rolled sheet is made of hot rolled coil as raw material, and is rolled below the recrystallization temperature at room temperature, including plate and coil. Cold rolled thin steel plate is the abbreviation of ordinary carbon structural steel cold rolled plate, also known as cold rolled plate, commonly known as cold plate, sometimes mistakenly written as cold rolled plate. Cold plate is made of ordinary carbon structural steel hot rolled steel strip, and is further cold rolled into a steel plate with a thickness of less than 4mm. Since it is rolled at room temperature, no iron oxide scale is produced. Therefore, the surface quality of cold plate is good and the dimensional accuracy is high. In addition, after annealing, its mechanical properties and process performance are better than those of hot rolled thin steel plate. In many fields, especially in the field of home appliance manufacturing, it has gradually replaced hot rolled thin steel plate;
