[0034] A method for using a welding process device, the method comprising the following steps:

[0035] S1: hoist the round pipe through the docking ring 2-2;

[0036] S2: Rotate the screw 2-3-4 to drive the slotted rod 2-3-1 to rotate and clamp the round tube;

[0037] S3: Push the docking ring 2-2 to drive the round tube to move to two grinding units 4-7, and grind it through the grinding units 4-7;

[0038] S4: Control the electric telescopic rod 4-5 to make the welding handle unit 4-8 lean against the groove of the two round pipes for welding.

[0039] The working principle of the present invention is:

[0040] When using this device, the round pipe to be welded is hoisted up, passed through the docking ring 2-2 respectively, and the docking ring 2-2 is located at the center of the round pipe, and then the screw rods 2-3-4 arranged on the two docking rings 2-2 are rotated respectively to make the screw rod 2-3-4 move outward, and the screw rod 2-3-4 moves through the hinge block 2-3-3 to drive the linkage rod 2-3-2 to slide along the groove rod 2-3-1, and drives the groove rod 2-3-1 to rotate relatively to clamp the round pipe through the anti-slip pad, so as to complete the fixation of the round pipe. At the same time, the synchronous movement of the two positioning devices 2-3 can play a centering role for the round pipe. After the round pipe is fixed, the docking ring 2-2 is pushed to make the slide seat 2-1 slide along the slide groove 1-1, and the slide groove 1-1 plays a role of limiting, thereby driving the two round pipes to move relative to each other, move to the two grinding units 4-7 to stop, and then tighten the top screw to fix the slide seat 2-1. This device is connected An external power supply is used to energize and extend the electric telescopic rod 4-5, and the two grinding units 4-7 are driven to move downward through the fixed plate 4-6 and respectively press against the groove of the circular tube. Then, the driving motor of the lower roller 4-2 is energized to drive the lower roller 4-2 to rotate. The lower roller 4-2 rotates and passes through the limit of the upper roller 4-4, and moves along the annular groove 3-1 set in the guide ring 3, so that the grinding unit 4-7 can grind the groove until the groove is polished flat. The electric telescopic rod 4-5 is controlled to shrink, and then the docking ring 2-2 is pushed to move to dock the two circular tubes. Then, the electric telescopic rod 4-5 is controlled to extend so that the welding handle unit 4-8 presses against the groove of the two circular tubes for welding. At the same time, the welding handle unit 4-8 is driven to rotate by the lower roller 4-2, so as to complete circular welding, which can replace manual automatic welding and make the welding interface smoother and firmer.

[0041] When grinding the groove: the conical grinding head 4-7-1 can grind the V-shaped groove; the groove is added into the V-shaped opening 4-7-2, the X-shaped groove can be grinded, the annular grinding head 4-7-3 can grind the U-shaped groove, and the conical grinding head 4-7-1 and the annular grinding head 4-7-3 can cooperate to grind the Y-shaped groove, so that the conical grinding head 4-7-1 is against the inclined surface, and the top surface of the annular grinding head 4-7-3 is against the vertical surface.
