BAIC Foton Beijing Base Cooperation Case: Laser Welding Empowers Roof Brazing Rework and Quality Improvement

Haoqiong Connection has partnered with BAIC Foton Beijing Base to provide customized manual laser welding solutions for core roof laser brazing rework scenarios, precisely addressing the pain points of low efficiency and high deformation risk in traditional rework processes, and helping BAIC Foton ensure structural reliability and appearance consistency of commercial vehicle bodies with high-quality repair technology.

Core value of manual laser welding: adapting to commercial vehicle rework needs

Flexible handling of complex defects: manual operation combined with precise focused laser allows for rapid localization and repair of various brazing defects such as porosity, undercut, and missed welds, adapting to the complex curved surfaces and weld dead corners of commercial vehicle roofs without the need for additional tooling adjustments.

Low heat input to prevent deformation: The laser heat source is concentrated, with a heat-affected zone only one-quarter that of traditional welding processes, effectively preventing secondary deformation of the roof base material, ensuring dimensional accuracy for commercial vehicles, and meeting Foton's stringent assembly standards.

Efficient rework cost reduction: No pretreatment grinding required, direct re-welding on defective areas. Repairing 10cm defects can be completed in just 30 seconds, improving efficiency by over 50% compared to traditional rework processes; The weld forms are smooth, reducing subsequent grinding steps and lowering labor and material costs.

Strong and tough connection ensures safety: The laser metallurgy bond is tight, and the weld strength after repair matches the original brazed weld seam, offering excellent corrosion and fatigue resistance, meeting the structural stability requirements of commercial vehicles under long-term complex road conditions, and eliminating the risk of cracking and leakage after rework.
