SGH-1250 Flash Butt Welding Machine
Features
- The machine features an automatic cleaning function for removing welding slag from both the electrode surface and the sides of the electrode jaws.
- It adopts a manually assisted feeding and unloading method.
- It is equipped with quick-change tooling. The electrodes and jaws are clamped by hydraulic or similar mechanisms, enabling rapid replacement.
- It includes a welding-parameter monitoring system capable of generating curves/data tables for parameters such as welding displacement, pressure, and energy. These curves and data records can be recalled and reviewed at any time.
- It can automatically adjust the electrode height, and the jaw clamping force is adaptively and evenly applied to the electrode to achieve accurate surface correction.
- It is equipped with fully enclosed welding-splash protection to prevent operator burns, along with a fire-resistant fume-collection hood.
- Welding slag generated during the process is contained within an enclosed protective cover and cleaned regularly to ensure operator safety. A rear access door on the protective cover allows workers to easily remove slag and perform maintenance.

Roll Forming Machine
The roll forming machine is specifically designed to form flared rims into their final profile. In standard production, three identical units fitted with different forming rollers are required to complete the full forming process. The system is composed of the machine frame, support bracket, hydraulic system, pneumatic system, and electrical control system.
