Welding Technology of Large Section Copper Bus Line Tungsten Electrode Argon Arc Welding
Tungsten electrode argon arc welding technology applied to large cross-section copper busbar is an important method for connecting two copper busbar or copper terminals. The application of this technology has the advantages of high welding quality, low cost and easy operation, making it an important welding technology for large section copper busbar connection.
The tungsten electrode argon arc welding method uses a tungsten electrode with a smaller diameter than the thickness of the welding base material to supply an electric arc. The heat generated by the arc is used to melt both the electrode and the welding base material. Argon gas is used as a protective gas to prevent oxidation of the weld pool and to increase the arc stability.
The welding process of large cross-section copper busbar tungsten electrode argon arc welding is mainly composed of five steps: preparation before welding, installation of welding equipment and pipeline, welding, removal of welding slag and inspection of welding quality.
Before welding, the welding ends of the copper busbar should be polished and cleaned to remove any dirt or oxidation layer on their surfaces. It is also necessary to ensure that the two welding ends of copper busbar are clamped firmly. After the installation of the welding device and pipeline, argon gas shall be filled until the pressure in the pipeline satisfies the weldering parameters. Then, the arc may be ignited at the correct welding position.
In the welding process, the heat of the arc should be adjusted to the value of the welding parameters, and the welding Should take place in the standard position with butter filing on the welding end. The flux should also be used properly. After completion of the welding, it is necessary to remove the weld slag from the welding surface and use a metal ruler to measure the size and position of the weld of the weld surface. Finally, the welding outlet should be checked To confirm whether it meets the requirements.
The application of the large cross-section copper busbar tungsten electrode argon arc welding can ensure high welding quality and high efficiency. Therefore, this technology is an important method for connecting two copper busbars or terminals.
