Robots for Resistance Spot Welding

Tespa India Pvt Ltd offers Robots for Resistance Spot Welding manufactured by Nachi Fujikoshi, Japan. Spot welding can be one of the most demanding robotic applications. Welding efficiency requires quick spot to spot movement and high payload capacity to accommodate a typical spot welding gun. Possessing these traits allows Nachi robots to excel in spot welding applications, especially when the required production rate is high. Nachi Fujikoshi is the leading supplier of spot welding robots in Japan and North America. Nachi's ST Fast Series (ST133F, ST166F, and ST210F) and ST Slim Series (ST70L and ST100) have an improved cable management system (CMS) that eliminates cable wear problems while expanding the usable range-of-motion. Power and communication cables as well as water and air hoses are completely contained within the CMS. Neat packaging of all utilities eliminates the risk of them getting caught on peripheral equipment. This advantage allows very accurate offline programming as the robot dress geometry is standard. The ST "Slim" Series robots (ST70L and ST100) were designed with an advanced space-saving concept making them ideal for compact systems or high-density, multi-layered installations. Servo gun technology is an important advance in spot welding. Nachi has led the industry in Servo Gun technology development and has improved weld quality and speed. Servo driven spot welding guns offer major advancements in spot welding technology. Servo driven spot welding guns have several distinct advantages over older pneumatic technology. Interfacing to the welding equipment is an important part of setting up any spot welding application. Nachi offers many interface solutions ranging from the fully integrated IWB (Integrated Welding Board) with Medar and Dengensha weld timers. Using IWB all relevant welding parameters can be programmed directly through the robot teach pendant. Fieldbus-type interfaces (DeviceNet, Profibus, Interbus, ControlNet) and standard but flexible descrete control are also available. The company also offers Material Handling & Welding Robots.
