Tungsten Inert Gas (TIG) welding, or Gas Tungsten Arc Welding (GTAW), is preferred for welding copper busbars because of its precision and control. Weld your busbars with ultrasonics to permanently benefit from strong connections without contact resistance — even with different metals like aluminum and copper. Discover the benefits of our innovative welding technology for more output, control, and efficiency in your production! to 12 s per. Although the technology behind electric vehicles (EVs) has been around for some time, the last decade as has seen a significant increase in the sale of EVs and hybrid electric vehicles (HEVs) as private motor vehicles. Especially in the manufacture of busbars, which are used in power distribution systems, electric vehicles and other high-current-carrying applications, choosing the right joining technology is crucial for. Busbars are flat conductors that are becoming part of the architecture of electric vehicles. Busbars are typically installed inside switchgear, distribution boards, and busway enclosures for localized high-current power distribution.
