Stretching Welding Sheet Metal Parts

1. What Are Stretching Welding Sheet Metal Parts?

Stretching welding sheet metal parts are formed by first stretching a metal sheet between two dies to achieve a desired shape, followed by welding along the seams. The stretching process is controlled to avoid over-thinning or structural weakening. After stretching, skilled technicians weld the seams using standardized parameters to ensure uniform joints and smooth surface finishes.

These parts are not typically subjected to post-weld stretching. Instead, the stretching occurs before or during forming, followed by welding to secure the final geometry.

2. Typical Manufacturing Sequence for Stretching Welding Sheet Metal Parts

Process Step	Description
Material selection	Steel, stainless steel, aluminum, etc.
Cutting	Laser or punching for blank preparation
Stretching	Controlled deformation between dies
Trimming	Removal of excess material
Welding	Seam or spot welding by certified technicians
Surface finishing	Grinding, deburring, or coating as required
