Welded? you must have some Century type abortion rifle or something? Normally the gas tube nut at the reciever is loosened (after removal of the piston of course)- the special spanner for this is nice to have - and pull the tube out of the front gas block

The gas tube threads into the gas block and is fixed in place by means of a small pin...visible once the gas regulator nut is backed off. If it's an STG variant, the gas tube is likely shortened and silver soldered to the gas block. Most all other variants will have a full length gas tube as described above.

Unscrew gas nut (from reciever), unscrew gas regulator but from gas block. Drive out gas tube pin, gas tube should unscrew from gas block. Most are not tight.

Thats exactly the way mine is. It doesnt come off.
