AutoWeld-EV8000: Deep Penetration Laser Welding for EV Chassis & Structural Parts

The AutoWeld-EV8000 delivers 8000W of fiber laser power for deep penetration welding of EV chassis components, battery tray frames, and structural aluminum extrusions. With a dual-beam optical configuration, it achieves full-penetration welds on 6mm aluminum alloy in a single pass — eliminating multi-pass MIG welding and post-weld distortion correction.

Key Features

• 8000W fiber laser with dual-beam (leading + trailing) configuration for porosity suppression
• Deep penetration: up to 6mm on 6061/6082/7003 aluminum alloy
• Seam tracking: laser line scanner with 0.1mm tracking accuracy for complex joint geometries
• Filler wire option: integrated wire feeder for gap bridging and alloy adjustment
• Gantry or robot mounting: configurable for straight seams or 3D contour welding
• Shielding gas control: argon/helium mixture for aluminum oxidation prevention

Technical Specifications

Applications

EV battery tray frames, skateboard platform longitudinal beams, door sill reinforcements, subframe assemblies, and aluminum extrusion joints for EV body structures.

Solving the Aluminum Porosity Problem

Aluminum laser welding is prone to hydrogen porosity from surface oxides and moisture. The EV8000's dual-beam configuration creates a stable keyhole with reduced vapor plume, combined with pre-weld laser cleaning capability to remove surface oxides — achieving porosity levels below 1% by cross-section area.
