Welding Positions QW431.1 and QW461.2
Basically there are three inclinations involved.

  • Flat, which includes from 0 to 15 degrees inclination
  • 15 - 80 degrees inclination
  • Vertical, 80 - 90 degrees
For each of these inclinations the weld can be rotated from the flat position to Horizontal to
