As intelligent manufacturing in the automotive industry advances at full speed, body-in-white (BIW) welding, as a core process in vehicle manufacturing, directly determines body structural strength, assembly accuracy, and overall vehicle safety performance

In vehicle manufacturing, weld quality is the core guarantee of body structure safety. A single passenger car body-in-white (BIW) contains 3,000 to 5,000 critical welds. Any defects such as incomplete fusion, missing welds, weld bumps, or cracks may lead to reduced body strength

With the explosive growth of the global new energy vehicle (NEV) industry, accelerated model iteration, multi-model line production, and the application of lightweight materials have become mainstream trends in the sector, placing new demands on the customization, flexibility,

As core equipment for logistics transportation, engineering construction and municipal operations, commercial vehicles feature **diverse categories, mixed specifications, complex working conditions and large batch variations**. Key components such as frames, axles, carriages, cantilevers and brackets come with wide size ranges, varied structural forms and stringent welding requirements,
