Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

It should be noted that the shielding gas jig of this embodiment can ensure that the telescopic cylinder provides a pressing force to the electromagnetic water meter 16 without affecting the rotation of the electromagnetic water meter 16 by setting a rotating shaft 6.9 at the lower end of the fixing seat 6.2, thereby facilitating the welding operation.

[0027] Preferably, the telescopic cylinder of the present embodiment is a gas cylinder 8, and the gas cylinder 8 is vertically fixed on a fixing bracket 9. It should be noted that the telescopic cylinder of the present embodiment may also be a hydraulic cylinder or an electro-hydraulic cylinder.
