Flexi Busbar Welding Feactures

High Joint Strength – Welded joints achieve up to 90–98% of the base material's tensile strength, ensuring permanent, solid bonding.
Perfect Metallurgical Bonding – The diffusion process creates atomic-level fusion without filler metals, resulting in seamless and impurity-free joints.
Zero Oxidation & No Porosity – The vacuum or protective atmosphere prevents oxidation, ensuring smooth, dense, and pore-free weld surfaces.

Excellent Electrical Conductivity – Welded busbars maintain over 98% conductivity compared with the original copper material, ideal for power transmission components.
No Material Deformation – Uniform temperature and pressure control minimize thermal stress, producing flat and dimensionally stable welds.
Smooth Weld Surface – The welded interface requires no additional grinding or polishing, achieving a clean and visually perfect joint surface.

High Repeatability & Consistency – Automated control system guarantees stable welding results across mass production batches.
Minimal Residual Stress – Controlled diffusion temperature profile eliminates internal stress, improving fatigue resistance and long-term reliability.
Strong Hermetic Sealing – Welded parts exhibit airtight and vacuum-tight sealing, suitable for battery, sensor, and aerospace applications.
Multi-Material Compatibility – Capable of welding copper, aluminum, stainless steel, titanium, and other conductive or dissimilar materials with uniform bonding quality.
