Spot Welding Robots

Nachi Robotics developed the first servo gun technology for spot welding.

Nachi Robotics continues to lead the industry in development of advanced robotic spot welding solutions, focused on making higher quality welds faster than ever before. Using advanced integration technology, all welding parameters and process critical data are programmed directly through the robots full color touch screen teach pendant.

NRSĀ dominates the robotic spot welding industry by:

  • Using advanced application software to simplify weld schedule programming
  • Performing in process quality validation
  • Maximizing throughput

If you need high performance spot welding robotic technology, contact NRS to see how we can improve your weld quality and increase throughput today.

Nachi has been an industry leader in spot welding robot technology.

They continue developing new welding solutions to provide better and faster welds. Nachi’s latest spot welding technology is integrated to the industries fastest industrial robots, the Nachi SRA Series. SRA series robots provide the industry’s most advanced spot welding controls and software functionality. Utilizing fully integrated weld controls, all spot welding data can be directly input and monitored through the robot’s teach pendant. Create detailed weld schedules unique to your application and material types with ease using the full color touch screen graphical spot welding user interface. Nachi Robotics’ SRA series reduces spot welding times by 30% over previous models through improved motion control, improved arm rigidity, vibration suppression, and acceleration performance.

Nachi Robotics SRA robots also offer A-Trac cable management systems to simplify:

  • Routing of power cables
  • Pneumatic lines
  • Water hoses
  • Signal cables to spot welding guns

A-Trac packages all spot welding utilities neatly to minimize the chance of snags or crashes with peripheral equipment and work cell objects.

Features & Benefits

Improved Productivity

Improved Productivity

  • Servo motor driven gun allows programming to any gun tip position within gun limits.
  • Gun motion is synchronized with the robot to reduce cycle time. Programmed tip force is achieved in one-third the time of a conventional air gun.

Improved Weld Quality

Improved Weld Quality

  • Precise pressure control reduces welding expulsion and tip wear.
  • Impact is 3x less than an air gun eliminating workpiece deformation and reducing tip wear.

Enhanced Flexibility

Enhanced Flexibility

  • One gun is now flexible enough to weld throughout a wide pressure range for variable metal thicknesses.

In Process Quality Control

In Process Quality Control

  • Measures thickness of parts at each weld at any pressure.
  • Automatically detect missing or misplaced parts.

Equipment Cost Reduction

Equipment Cost Reduction

  • Simplified features and the elimination of pneumatic systems reduces initial cost.
  • Never worry about air leaks with electric servomotor driven spot welding guns.
  • Improvement of operability, longer tip life (more than 30%), and improved energy efficiency reduces operating costs.

Environmental Improvement

Environmental Improvement

  • Elimination of air exhaust noise typical of pneumatic spot welding guns
  • Reduced welding expulsion
