Toptig

A new robot welding process for industry

Toptig

TOPTIG process is a major innovation in the world of robotized welding. Developed in the Lincoln Electrical research centre, TOPTIG is a new process development from arc welding classical solutions. This new process can be used effectively on carbon or stainless steel plates up to 3 mm as well as on Titanium or Nickel alloys or on galvanized sheets with weld brazing.

TOPTIG innovative process principle

The filler metal is fed through the nozzle directly into the arc with an angle of 20° to the electrode, precisely where the temperatures are the highest. This concept guarantees a high deposition rate and an efficient metal transfer. Parameter adjustments permits the choice of a liquid bridge transfer or a droplet transfer mode. In addition the wire speed can be pulsed and synchronized with the current, giving a waved weld bead appearance. Whatever the parameters selected, due to the precise control of energy, the TOPTIG process guarantees a TIG quality result with a complete absence of spatter and avoids distortion on thin sheets.
