A7 TIG Orbital System 300

Multi-layer welding made easy

Professional mechanized TIG orbital welding system for multi-layer welding of pipes and tubes



More details

A7 TIG Orbital System 300 with open head clamp is the most advanced professional TIG orbital welding solution for multi-layer welding of tubes and pipes with an outer diameter of 25 – 355 mm. With the system, complicated high quality multi-layer welds become simple to weld with an easy-to-use auto-programming function and automatic height sensing. The system is suitable for a wide application area and can be used both for pipe-to-pipe and pipe-to-fitting welds. All functionalities such as controller, power source, and water cooling are integrated in one robust chassis. The system is operated with intuitive remote controller.

Benefits

  • Gain significant savings in production time and amount of rework through easy to learn and use auto-programming.
  • Save in investment costs since the same equipment can be used for pipe-to-pipe and pipe-to-fitting welds.
  • Compact head design is ideal for smaller diameter pipe applications with limited radial and axial clearance around the weld.
  • Pulse technology produces consistently high-quality welding seam.
  • Automatic height sensing saves setup time and rework. No need to manually adjust the height during the welding cycle because the arc voltage control enables constant weld quality.
  • Optimum result is guaranteed also in most challenging cases because the weld head functionalities are designed to mimic all motions of a skilled welder.
  • All functions are accessible via one easy-to-use remote controller. Adaptive auto-programming makes it easy to set up the welding parameters using automatic calculation. Controller has a graphical user interface and clear color display. You can use the remote controller to create, modify, and manage programs.
  • Welding values and electrode movements can also be fine-adjusted during welding. The system automatically offers to adapt the welding program according to changes.
  • The heat-tolerant welding head with water-cooled housing is suitable for use on CrMo and other alloys that require preheating.
  • Programs can be stored in internal memory.
  • Welding parameters can be printed on paper or saved on a USB stick.
  • Integrated printer for printing the welding parameters on paper

SAVE 35 % IN WELDING TIME

The mechanized transportation of a welding head in A7 TIG Orbital System 300 provides a steady and accurate welding position. This enables stable welding quality and the use of optimized welding parameters during welding. As a result a shorter arc on time per weld is needed and the welder can weld more welds in a working day. The typical saving in welding time for A7 TIG Orbital System 300 is 35 % compared to manual MMA welding.
