en.Wedoany.com Reported - TRUMPF will present its latest laser applications and solutions for the automotive industry at booth W1-B01 during the Shanghai International Automotive Manufacturing Technology, Equipment and Materials Exhibition (AMTS 2026), held from July 8 to 10, 2026. The focus will be on the advantages of laser helical spot welding in body-in-white manufacturing, laser welding as a replacement for traditional brazing in new energy vehicle liquid cooling plates, and high-speed laser cladding technology for brake disc manufacturing that meets Euro 7 and China 7 emission standards.

In the manufacturing of new energy vehicle liquid cooling plates, traditional brazing furnace processes suffer from high energy consumption, large equipment footprint, high gas costs, and issues such as deformation and leakage in long weld seams. TRUMPF's laser welding solution significantly reduces energy consumption, eliminates the need for flux and solder, removing the risk of chemical residue, while offering high processing flexibility and rapid on/off switching to lower operational costs. This solution employs a laser 3D five-axis machining system equipped with a four-focus optical design and closed-loop laser power control technology, combined with process monitoring, to adapt to the high reflectivity of aluminum alloys, ensuring stable and reliable weld seams in flow channels, improving weld strength, and reducing leakage defects.

Addressing the EU's Euro 7 emission standards for particulate matter from braking systems, TRUMPF applies high-speed laser metal cladding technology to the coating hardening process of brake discs, enabling the production of brake discs with near-zero particulate emissions. The BrightLine Weld adjustable ring-core beam technology and beam shaping dual-focus technology overcome the challenges of efficiently cladding hard layers on cast iron substrates, improving powder utilization and adhesion efficiency while reducing production costs. This technology also endows brake discs with excellent corrosion resistance, solving the problem of rust on mechanical brake discs in electric vehicles caused by frequent use of regenerative braking.

In automotive body-in-white manufacturing, laser helical spot welding is gradually replacing traditional resistance spot welding to meet the lightweight and safety requirements of materials such as hot-formed sheets, high-strength steel, and galvanized multi-layer sheets. This solution incorporates laser remote welding technology and a 3D intelligent scanning head, enabling precise welding on three-dimensional curved surfaces. In the welding of thin-walled components like doors, OCT real-time penetration depth detection technology measures penetration parameters non-destructively with millisecond-level time resolution, and a closed-loop feedback system automatically adjusts parameters, ensuring full traceability of weld quality. In the manufacturing of Vehicle" target="_blank">new energy vehicle motors, the VisionLine image processing system and high-speed galvanometer solve the precision positioning and welding challenges of stator flat copper wires, combined with AI technology to enhance quality and production capacity.

Through process design and intelligent system configuration, TRUMPF's laser helical spot welding solution achieves a balance of high quality, high efficiency, and low cost in body-in-white welding, and is increasingly being adopted by automotive manufacturers.
