It is not arranged on by bearing in sleeve, sleeve both ends are respectively provided with the end cap of fixing bearing position, and mandrel is provided with center
Through hole, through hole one end are connected with protective gas pipeline, and the other end is provided with internal thread, and locating shaft is connected by external screw thread with mandrel,
The blind hole being connected with the through hole of mandrel is provided with the locating shaft, locating shaft circumference is provided with multiple protection gas connected with blind hole
Hole.
In the above-mentioned technical solutions, the locating shaft is transition axis and welding axle, and the transition axis is multi-diameter shaft, its big end
Provided with the external screw thread being connected with mandrel, the welding axle is provided with the external screw thread being connected with mandrel, is provided with its axle center and connects with through hole
Logical gas port.
In the above-mentioned technical solutions, reinforcement is provided between the column and base.
In the above-mentioned technical solutions, it is bolted between the end cap and sleeve, sleeve is provided with screwed hole.
The beneficial effects of the utility model are：In welded stub connection and stainless steel tube, pipe joint and stainless steel tube are put
Put on locating shaft, while become by protecting stomata to spray inert gas to welding position, when side is welded and rotate, mandrel is logical
Cross bearing and sleeve connection, frictional resistance very little, rotate it is very convenient in the pipe joint and stainless steel tube of welding, therefore can be with
When weld seam be it is successive, until welding initial position, weldquality is reliable, will not also be aoxidized inside weld seam, without debris
Produce；The axiality of pipe joint and stainless steel tube is ensure that due to the support of locating shaft, during welding.
