What Is The Applicable Material Thickness Range for A 1500-watt Laser Welding Machine in Lithium Battery Welding?

In lithium - battery manufacturing, many businesses ask, "How thick can a 1500W laser welder bond lithium - battery parts?" The answer isn't simply about power; it's a complex interplay of material properties, welding process, and equipment performance. With our extensive 10 - year experience in laser automation, this article offers an in - depth analysis.

 I. Material - indeterminate Weldable Thickness

Lithium - battery welding materials vary. Metals like aluminum and copper have high thermal conductivity, dissipating heat quickly. At the same power, their weldable thickness is less than nickel. A 1500W laser welder can bond pure nickel up to 1.2mm per side. For aluminum, it's better to stay within 0.8mm per side to avoid incomplete fusion and virtual welding.

 II. Welding Process - indeterminate Welding Results

The welding process significantly impacts weldable thickness. Tab welding and spot welding have different thickness capacities. Tab welding, which penetrates two layers, has a limited total thickness. For nickel tab welding, around 1.8mm total is ideal. Also, matching welding speed to laser energy is essential. Incorrect speed causes welding defects, requiring repeated adjustments.

 III. Equipment Performance - indeterminate Key Factor

Different manufacturers' 1500W laser welders vary in performance. High - quality ones with good beam quality and stable energy output can bond thicker materials. Some small - scale manufacturers' devices, despite claiming 1500W, have unstable energy, struggling to weld even 0.8mm aluminum sheets.

 IV. Practical Suggestions for Selecting a 1500W Laser Welder

When purchasing, bring samples to the manufacturer for on - site testing. Inspect melt depth, width, and defects. Also, check the equipment's energy adjustment precision for accurate thickness control.

After this professional analysis, it's clear that the weldable thickness of a 1500W laser welder depends on material, process, and equipment performance. Only by considering all these factors can you choose the right new - energy lithium - battery laser welding equipment for your production needs.
