Welding tracking device for pipe fittings

The invention provides a welding tracking device for pipe fittings. The device comprises a welding gun, an electric sliding rack and an angle connecting plate, wherein the electric sliding rack is connected with the welding gun and equipped with a driving mechanism which drives the welding gun to axially reciprocate. The device further comprises an angle adjusting mechanism for adjusting the welding angle of the welding gun, wherein the angle adjusting mechanism comprises a rotating shaft which is in rotary connection with the electric sliding rack and the angle connecting plate. According to the device, the existing moving mode of the welding gun and a tungsten electrode under the welding of a pipe plate can be changed, and accurate and stable arc controlling and tracking can be achieved. Therefore, the defects in welding can be decreased, and the welding efficiency and quality can be improved.
