With the development of oil and gas pipelines to large diameter, long distance, high strength and high pressure, the welding difficulty is higher and higher, and the requirements for welding quality are higher and higher. Manual arc welding and flux cored wire semi-automatic welding are difficult to meet the requirements of pipeline welding. Fully automatic welding machine can easily complete this process. In the construction of pipeline engineering, the welding quality is one of the very important links to ensure the engineering quality, and the welding efficiency also directly affects the construction progress, that is to say, the welding quality and welding progress determine the quality and progress of the project to a great extent.
Full automatic welding machine equipment, the pipeline is fixed, and the welding car rotates around the pipeline to realize the welding of the pipeline in all positions (plane, vertical and upward). The welding process is completed by machinery and microcomputer and is not affected by human beings. Therefore, the pipeline all position automatic welding machine has the advantages of good weld quality and high welding efficiency.
Process characteristics of fully automatic welding machine:
1. The larger the applicable pipe diameter, the thicker the wall thickness, which can better reflect the welding process.
2. The welding process parameter input device can store multiple sets of welding process parameters and flexibly select multiple welders and steel pipes of different specifications;
3. Most of the welding process parameters of the pipeline automatic welding machine are input through the welding process parameter input, and the welder cannot modify them to ensure the accuracy of the welding process parameters; 4. High welding efficiency, which can be increased by 2-5 times compared with manual arc welding;
5. Welding arc combustion is relatively stable;
6. The weld is flat and beautiful, and the internal quality is good.
