Examples of Welding Services We Provide

1. Arc Welding (SMAW)
Suitable for repairing shafts, steel structures, machine bases, and bearing housings. This method provides high structural strength and is ideal for heavy-load applications such as machinery foundations and industrial equipment supports.

2. CO₂ / MIG Welding (GMAW)
Delivers smooth, clean, and continuous welds, ideal for machine frames, housings, covers, and thin metal structures. Commonly used in automotive parts manufacturing and electrical equipment production.

3. TIG Welding (GTAW)
Used for components requiring high precision and refined weld appearance, such as stainless steel piping, aluminum parts, lightweight structures, and fuel tank covers, where cleanliness and weld quality are critical.

4. Repair Welding & Maintenance
Repair of cracks, fractures, and worn areas on machinery components including gear heads, gear teeth, valve seats, and guide rails. Our technicians inspect and restore parts to like-new performance, extending service life and reducing replacement costs.

In addition, we provide custom welding and assembly of machinery and industrial components based on drawings, supporting both small- and large-scale projects—such as automated machine frames, shaft support structures, and production line assemblies—to ensure strict compliance with customer engineering requirements.
