COMPACT COLD-WELDING EQUIPMENT AND APPLICATORS 1. Nitriding of dies is not required. The hardness of tungsten carbide coating is more than 70 HRC, which is higher than hardness obtained by nitriding process (62-64 HRC). 2. Increased die life due to high wear resistance. 3. Substantially reduced maintenance downtime of dies and tools. 4. Ability to coat selective areas of dies that are prone to wear. The process does not require the complete die to be treated/protected. COMPACT COLD WELDING EQUIPMENT AND APPLICATORS 1. Skilled welders are not required. It can be carried out by anyone. 2. Open spac /ducti g are not required. No fumes are generated during col welding. 3. It is a time saving process as dies need not be removed from forging equipment. 4. Pre- and post-welding heat treatment is not necessary. No stresses are generated during cold welding as it is a cold process. Additional benefits of Japanese Cold Welding Technology: 1. Nitriding of dies is not required. The hardness of tungsten carbide coating is more than 70 HRC, which is higher than hardness obtained by nitriding process (62-64 HR ). 2. Increased die life due to high wear resistance. 3. Substantially reduced maintenance downtime of dies and tools. 4. Ability to coat selective areas of dies that are prone to wear. The process does not require the complete die to be treated/protected.
