Abstract

The invention discloses an automatic welding device for argon tungsten-arc welding of a deep hole in the inner wall of a pipe fitting. The automatic welding device comprises a workpiece pairing system for quickly and precisely pairing workpieces to be welded; a welding machine head sliding and fixing device for quickly positioning a welding machine head; an automatic arc length tracking device; a tungsten electrode swing control and automatic centering device; a wire feeding control system; and a real-time video monitoring device which is used for monitoring the welding state in the welding process and has a video recording function. The argon arc welding device can well adapt to the complex argon arc welding environment of the inner wall of the pipe fitting. The device has the following advantages that: the overall structure is compact, and the device can adapt to the argon arc welding working conditions of the inner walls of various pipe fittings, wherein (1) the workpiece pairing system can achieve rapid and accurate pairing; (2) the machine head sliding device can quickly and accurately position the machine head; (3) the video monitoring device can record the welding state, so that the traceability of the welding process is ensured; and (4) the argon arc butt welding of the deep hole in the inner wall of the pipe can be achieved, and the fillet welding of the deep hole in the pipe can be achieved through design change.

Description

Technical field [0001] The present invention relates to the field of intracaviped tungsten argon argon argon arc welding in the tube inner wall. Specifically, a tungsten argon arc welding automatic welding device for a deep-in-tube inner wall in a small finite space in a small finite space. Background technique [0002] In many engineering occasions, the solder or pairing is required inside the smaller diameter pipe. In this application environment, on the one hand, the space is small for the size of the welding device, and the welding process is not easy to observe, and it will not be able to make a lot of inconvenience to the welding operation, and the final welding cannot be guaranteed. quality. In order to solve this welding problem, the automatic welding apparatus of the inner wall deep hole tungsten argon arc welding is a practical solution. Inventive content [0003] The main solution of the present invention is to provide an automatic welding apparatus for pipe welding i...
