Problems solved by technology
[0005] Therefore, as far as its welding process is concerned, it is a relatively complicated process, which is time-consuming, labor-intensive and material-consuming.
So this welding method is very stupid, and its efficiency is self-evident, very low

Embodiment
[0036] First, the welding torch moves forward rapidly 8mm at a speed of 69cm / min. Then the speed is reduced to 34.5cm / min, and the backward overlapping movement is 4mm. During the fast forward movement, the arc acts on the root edge, the arc melts the root, creates a weld puddle and forms a back weld. During the backward movement, the arc acts on the molten pool, so that the molten droplets produced by the melting of the welding wire can transition well into the molten pool, thereby obtaining a stable weld. In order to ensure short-arc welding, the height of the welding torch changes with the change of position. In the process of moving forward, the height of the welding torch is lower than 4mm, while in the process of moving backward, the height of the welding torch is higher than 4mm, and the pulse current is 100Hz. The purpose of reducing the welding current at the center of the lateral swing is to reduce the influence of the arc brightness on the shooting effect of the C...

Description
technical field [0001] The invention discloses a multifunctional welding machine for electrolytic aluminum single-gap welding aluminum busbar and its welding process, belonging to the technical field of electrolytic aluminum. Background technique [0002] The aluminum bus bar of the electrolytic aluminum plant is a very important and indispensable main conductor for power transmission in the process of producing electrolytic aluminum in the electrolytic aluminum plant. [0003] However, at present, there is no ideal welding method for connecting aluminum busbars to aluminum busbars, that is, how to weld aluminum busbars more, faster, better, and economically, and there is no better welding method. Equipment and process. [0004] As far as the current traditional aluminum busbar and aluminum busbar butt welding process is concerned, it is a relatively complicated, multi-layer stacked transitional aluminum plate, using two gap welding methods. That is: firstly, at the place ...
