The 3-axis QCW laser welding machine combines a QCW fiber laser with programmable X/Y/Z positioning for welding small and medium-sized metal components that require controlled heat input and repeatable welding positions.
QCW Laser Performance
The two models are differentiated mainly by their available energy and peak power.

Welding Advantages for Production
Localized Welding for Thin Components
For battery tabs, thin shielding covers, and small housings, the pulsed output concentrates energy at the joint and limits unnecessary heating of the surrounding material.
Controlled Penetration
0.2–50 ms pulse width and 15J/30J maximum input energy allow the welding process to be adjusted for different materials and thicknesses.
High Peak Power
HT-QCW150 reaches 1500W peak power; HT-QCW300 reaches 3000W. High peak power provides concentrated instantaneous energy for localized melting and penetration.
Automated 3-Axis Precision (X/Y/Z)
Automates multi-point positioning and focal height adjustment across complex geometries, eliminating manual repositioning and ensuring micron-level repeatability across high-volume batches.
Stable Laser Output
Both models provide ±1% power stability, supporting consistent laser output during repeated production.

Welding Applications
Battery Manufacturing: Joins battery tabs, poles, and terminals. Pulsed thermal control restricts heat spread around sensitive cell structures, ensuring stable melt pool formation.
Electronics & Electrical: Welds copper terminals, wire harnesses, and thin electronic housings. CNC-programmed positioning delivers repeatable multi-point welds.
Sensors & Instruments: Seals stainless-steel and aluminum sensor bodies with precise penetration depth and seam alignment across high-volume production runs.
Precision Assemblies: Joins intricate brackets, small housings, and micro-connectors. Automated 3-axis motion minimizes manual handling and reduces cycle times.
Mold & Tooling: Restores worn mold edges, dies, and precision tooling. Concentrated pulse energy confines thermal exposure strictly to the weld zone, preventing base metal warping.

FAQ
Q: Can you test our workpieces before we order?
A: Yes. Send the material, thickness, part drawing or sample, joint type, and required weld result. We can evaluate the welding process and recommend the appropriate laser configuration and starting parameters before you select equipment.
Q: What information is needed to configure the machine?
A: Key information includes workpiece dimensions, welding-point locations, material thickness, required focal position, and production method. This determines the XYZ travel, worktable, fixture, and positioning configuration.
Q: Can the machine be integrated into an existing production line?
A: Yes. The machine can be configured for automatic loading/unloading and connection with upstream or downstream equipment when the production process requires it. Integration requirements should be reviewed from the workpiece handling and cycle process before quotation.
Q: What documents are available for equipment procurement?
A: Qualification and technical documents can be provided according to the project, including ISO 9001:2015, CE, and FDA certification documents, together with relevant equipment documentation for supplier evaluation and procurement.
