| 摘要 |
The invention relates to a device for inert gas arc welding of circular seams comprising a welding head (13), in particular an orbital welding head with a consumable electrode (23), which is connected to a drive and can be moved along a circular welding groove, and to which an inert gas chamber (20) is allocated.
<??>In order that, during the arc welding process, preferably the pipe-to-pipe welding process, access of air to the weld be prevented and hence hardening and damage of, in particular, gas-sensitive materials be avoided in a simple manner, the inert gas chamber (20) is fixed to the rotating welding head (13).
