Kat® 200

Our Kat® 200 series features both flexible and rigid track designs:

Flexible Track

The Kat® 200 Flexible Track carriage features a flexible track that can be positioned to follow the contour of the workpiece, allowing it to work on curved surfaces. Using a self-aligning wheel system, the carriage moves closely against the workpiece, gripping the top and bottom of the track for exceptionally accurate welds along any plane.

Benefits and Features:

  • Welding Carriage
  • Variable Speed
  • Easy Mounting and Removal
  • Programmable
  • All Positions
  • Low Voltage

Rigid Track

The Kat® 200 rigid track is a reliable and rugged precision orbital welding and cutting travel carriage. It is designed for use on a rigid track, enabling it to operate on any plane. The rigid track can be formed for use on curved surfaces or used in straight sections.

Benefits and Features:

  • Welding Carriage
  • Variable Speed
  • Programmable
  • All Positions
  • Low Voltage

What is Orbital Welding?

Orbital welding uses automation technology to weld stationary tubes, pipes, and other cylindrical components by moving the electrode in an orbit around the workpiece. This welding method is ideal for tubes in hard-to-reach positions that can be difficult to access manually.

The orbital welding process can be fully automated for high-volume, repeatable pipe and tube welding. To handle smaller batches or custom components, a variety of semi-automatic and mechanized machines may be utilized.

Why Consider Using Orbital Welding Machines?

Orbital welding machines offer numerous advantages over more traditional welding systems, including:

  • Enhanced Productivity. With automated orbital welding systems, you increase productivity by creating highly accurate welds with greater speed and repeatability. Setup is also quicker and much less labor-intensive, which saves you additional time and effort.
  • Superior Precision. Using the latest automation and mechanization, you can rely on orbital welding to produce extremely precise results with less risk for human error.
  • Improved Workplace Safety. Orbital welding systems can operate reliably in inaccessible and dangerous locations that would put manual welders at risk. Using automation technology allows your technicians to operate from a safe distance without the risk of injury.
