Achieve significant cost reduction while maintaining sufficient welding strength!
"Projection welding" refers to the process of applying pressure through electrodes to contact two metal surfaces and passing a large current through them, causing the contact area to reach welding temperature due to heat generated by electrical resistance, thus bonding them together. Compared to arc welding, which can cause discoloration and oxidation at the weld area, projection welding has the characteristic of concentrating heat only at the contact area for a very short time, resulting in minimal discoloration of the weld. For projection welding bands, trust the expertise of Jounai Seisakusho, which boasts a shipping record of over 9 million units in 20 years. [Features] - Surface-treated steel plates can be used directly as products, eliminating the need for post-welding plating. - Short welding time improves production numbers. - No discoloration due to heat, resulting in a good appearance. - The welding strength is sufficient for practical use. *For more details, please refer to the PDF document or feel free to contact us.
