The Spot Welding Robot System is a 6-axis resistance spot welding workstation for high-current sheet metal joining in automotive body, home appliance, and structural frame production lines.
We supply an integrated resistance welding cell comprising the high-torque BRTIRUS1820A industrial robot, machine-mounted spot welding transformer, pneumatic C-type spot welding gun, elevated mounting base, and an integrated electrical control cabinet.
Key Advantages
Precision Welding – ±0.05 mm repeatability ensures consistent weld placement across all parts.
High Load Capacity – Supports up to 20 kg, accommodating spot welding clamps, transformers, and accessories.
Flexible Multi–Angle Welding – 6-axis robotic arm enables complex part welding without frequent fixture changes.
High Efficiency – Rapid cycle (~0.5 s per weld point) maximizes throughput and production line output.
Safety & Compliance – Wrist IP54, body IP40; compliant with EN ISO 13849 safety standards.
