[0002] The existing publication number (CN203380530U) discloses an intersecting line welding machine, which is composed of welding parts, welding gun, double-hole adjustment slider, three-jaw chuck, rocker, arc guide, motor, gantry, adjustment slider, adjustment rod, linear guide, arc slider, machine base, fixing bolts and support rods. The support rod is fixed to the machine base by fixing bolts, the arc guide is fixed to the support rod, the arc slider is placed in the arc guide, the arc slider is connected to the linear guide through a rocker, the gantry is fixed to the machine base, the motor is fixed to the gantry, the adjustment slider is sleeved on the adjustment rod, the double-hole adjustment slider is sleeved on the linear guide, and the welding gun is connected thereunder. The utility model provides an intersecting line welding machine suitable for mass welding production of large quantities of workpieces;

[0003] Although it can weld along the intersection line, the positions of the two pipes need to be fixed in advance before welding. The existing operation is to make a few spot welds at the intersection welding point by manual welding, and then weld. However, this greatly increases the difficulty of the work and requires people with welding experience to operate, which is costly. In addition, the weld of the device covers the original spot weld, which will cause the welding quality to be uncontrollable and increase the difficulty of subsequent grinding of the weld. Utility Model Content

[0011] Preferably, the inner tube fixing head is threadedly connected to the adjusting rod, and the tail end limiting end is threadedly connected to the adjusting rod, which effectively improves the convenience of installation and is convenient for replacement.
