1.Selecting high-quality carbon steel as the raw material, which boasts favorable mechanical properties, including strength and toughness and demonstrates stable performance during bending, punching and other processing procedures.

2.CBIES uses advanced high-frequency welding technology to ensure the consistent quality of weld joints, effectively minimizing welding defects. This approach enhances the strength and fatigue life of welded areas, thereby guaranteeing the safety of the product during usage.

3.During the welding process, strict control is exerted over welding parameters such as current, voltage and speed to ensure the integrity of the weld quality. Additionally, post-weld treatments are implemented, including online cleaning of the weld seam and real-time inspection for flaws, to confirm there is on defect such as cracks, incomplete penetration and slag inclusion in the welded areas.
