Welding Machines

Machine Welding, also known as Automated Welding or Mechanised Welding, uses machines such as:
• Column & Boom
• Welding Lathe
• Seamer
• Gantry Welder
• Welding Tractor
• Welding Carriage
• Custom Welding Machines

Need for Laser Seam Tracking

Automatic welding uses welding machines to make welds automatically, in most cases without direct operator control. Welding machines normally execute fairly simple 3Dtrajectories, often straight line or circular paths.

However, without sensing, these weld paths are relative to the machine itself. Ideally, the correct weld trajectory should be relative to the parts to be welded. This is where laser seam tracking comes in. By sensing the actual joint, the laser seam tracking system corrects the weld path to follow the true path of the joint rather than a nominal weld path.

Benefits of Laser Seam Tracking

Benefits from the ability to follow the true weld path rather than a nominal path include:
• higher quality welds in the correct place in the joint
• reduced rate of weld defects
• reduced scrap/rework rate
• simplification of machine design and build
• improved productivity
