Description

Technical Field

[0001] This utility model relates to the field of welding technology, and more specifically, to a combined aluminum busbar welding mold. Background Technology

[0002] Aluminum busbars are frequently damaged unexpectedly during production or use. Currently, there are two main methods for welding aluminum busbars in China: one common method is gas welding, but this method is only suitable for welding thin plates with small surface areas and has low efficiency, limiting its practical application to localized repairs of small-sized aluminum strips; the other method is arc welding using an arc welding machine. However, in actual construction sites where the aluminum busbar cannot be powered off, the area will generate a strong magnetic field due to the electromagnetic effect of the strong current. When the welding power source is in the arc ignition stage, the arc sparks are interfered with by the strong magnetic field and splatter everywhere, making arc column formation difficult and prone to deformities. Simultaneously, severe arc blow and spatter significantly increase labor intensity and welding difficulty, directly preventing normal and effective welding.

[0003] Currently, there is a self-propagating welding repair method for aluminum busbars that effectively avoids strong magnetic field interference, improves welding quality, reduces labor intensity, and has relatively simple mold operation. This method, tailored to specific situations, involves selecting a self-fluxing flux with the optimal melting point and reaction rate for localized repair welding. Welding molds are crucial tools for self-fluxing welding. While similar molds have existed before, many practical welding repair locations are too narrow, and the working area cannot meet the placement requirements of standard molds, rendering them unusable. Furthermore, when large and irregular defects on the aluminum busbar surface require repair, general-purpose standard molds are often inadequate. Therefore, this application proposes a combined aluminum busbar welding mold to address this problem.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
