Kunlun Jing Dissimilar Metal Welding Technology, Fasteners & Equipment
Achieving high-quality Al/Steel joints in a single pretreatment-free step, breaking through industry limitations
Core Advantages:
(1) Ultra-High Strength Compatibility
Welds 2200MPa press-hardened steel with low-ductility cast aluminum, solving critical challenges in dissimilar metal joining
(2) Complex Condition Adaptability
Compatible with coated plates, structural adhesive composite conditions, and multi-layer Al/Steel stack combinations
(3) Stable Process Performance
Maintains consistent weld quality despite significant lap gap variations and sheet thickness tolerances
(4) Industrial-Grade Efficiency
<1s per weld cycle, preserving high-cycle-rate advantages of traditional resistance spot welding lines
(5) Low-Cost Implementation
Rapid integration via economical upgrades to feeding/gripping mechanisms on existing resistance spot welding equipment
