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.
| 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 |
| Industry | Typical Use |
|---|---|
| Automotive | Structural brackets, support frames |
| Aerospace | Enclosures, ducting components |
| Construction | Mounting plates, connection elements |
| General manufacturing | Equipment housings, protective covers |
Due to their strength and durability, Tiandubang stretching welding sheet metal parts are often selected for applications requiring reliable joint performance.
Tiandubang supports custom stretching welding sheet metal parts based on:
Custom parameters include material type, thickness, weld type (seam, spot, or pulsed), and surface treatment.
Since its establishment, Tiandubang Jiaxing Metal Technology Co., Ltd. has operated under an ISO9001 quality management system. Production planning, material inventory, and financial resources are managed through an ERP system. Each batch of stretching welding sheet metal parts undergoes dimensional and visual inspection before release.
