Optimization of the weld seam by strip edging

The optimization of the strip edge is a basic condition to benefit entirely of the advantages of modern welding methods.

Thanks to strip edge trimming by metal-cutting, the strip edges are steadily cleaned and straight meeting requested dimensions.

This results in the following advantages:

Tube welding line by TIN

  • less energy input
  • higher welding speed
  • less bulge and fewer rejections
  • minimized scrape rate
  • less strip width allowance
  • homogenous weld structure
  • better the weld seam and form quality
