We would like to share some results of orbital welding trails with You.

The application was orbital welding of quite small stainless steel pipe ø 6.0x1.0 mm

We used our Orbital S7 Compact MV power source and the CHW21 welding head with according collets

The welding time was about 16s with 4 sectors, first sector was with pulsing 33A for 0,125 s and 11A for 0.125s

For reproducable root welding it was neccessary to do some pipe facing before welding.

A clean surface and a sharpe edge will provide constant root shape.

The shielding gas was Argon 5.0 with flow of 8l/min for welding

Argon 5.0 gas was used also for backing gas with flow of 2.5 l/min.

During parameter optimization in the welding tests - we have achieved good root pentration and a very clean welding.
