Description
Technical Field

Background
Welding, also known as fusion, is a process and technique for joining metals or other thermoplastic materials, such as plastics, by means of heat, high temperature or high pressure, and the energy sources of modern welding are varied, including gas flames, electric arcs, lasers, electron beams, friction, ultrasonic waves, etc., and when welding the gas storage tank into and out of the gas pipe, a high welding precision is required to prevent gas leakage caused by missed welding or uneven welding due to a high internal pressure of the gas storage tank.
However, in the process of welding the air pipe, the welding operation of the air pipe of the air storage tank is generally performed by manually rotating the air pipe and moving the welding gun, so that the welding labor intensity is high, the working efficiency is low, the welding positioning accuracy is low, the welding leakage or welding non-uniformity is easy to occur, and the welding point of the air storage tank is easy to leak air.
An automatic welding device for a pipe joint of an air storage tank, which is shown in Chinese patent publication No. CN218362877U, comprises a frame, a clamp driving device, a positioning clamp, a welding head driving device and a welding head, wherein the clamp driving device, the positioning clamp, the welding head driving device and the welding head are fixed on the frame; the positioning fixture comprises a positioning bottom plate and magnetic iron positioning heads, the driving end of the fixture driving device is fixedly connected with the positioning bottom plate, and the magnetic iron positioning heads are respectively fixed on the positioning bottom plate; the magnet positioning head is provided with a positioning groove which is attached to the outer wall of the bottom of the air storage tank; the driving end of the welding head driving device is connected with a welding head, and the welding end position of the welding head corresponds to the welding position of the air storage tank; the clamp driving device is used for driving the positioning clamp to move to the welding station. The equipment reduces manual operation and labor intensity of workers; and in the welding process, the moving, positioning and welding of the air storage tank are automatically completed by the equipment, so that the degree of automation of the welding process of the air storage tank pipe joint is improved.
The device can realize the automatic welding process of the pipe joint of the air storage tank, but can only carry some air storage tanks which are small in volume and convenient to move so as to carry out a welding procedure, but when the air storage tank which needs to be processed is large and is not easy to move and carry, the welding equipment cannot adapt to the welding operation, so that the device cannot have strong adaptability, and the pipe joint cannot be ensured to be positioned on the same axis with the mounting hole of the air storage tank when the pipe joint is welded with the mounting hole of the air storage tank, so that the welding precision is influenced, and the welding position is easy to generate air leakage or a welding-off phenomenon.
