[0002] A spring is a mechanical part that uses elasticity to work. A part made of elastic material deforms under the action of an external force and releases elastic force when the external force is removed. It is generally made of spring steel. Springs are complex and diverse in types. According to the shape, there are mainly helical springs, scroll springs, leaf springs, special-shaped springs, etc. During the processing of springs, welding treatment needs to be carried out on them.
