QCW Pulsed Laser Spot Welder BP-W-P150 for Sensors and Medical Precision Parts

The BP-W-P150 is a platform workstation built around a QCW (quasi-continuous wave) fiber laser for precision spot welding of thin parts such as sensor housings, diaphragms, leads and medical small parts in stainless steel, titanium, NiTi, copper and aluminum. Free sample testing at our facility in Kunshan (Suzhou), China.

Specifications

Capability (typical, confirmed by sample tests)

Stainless steel, copper, aluminum, silver-plated parts, titanium and NiTi; thickness 0.1–0.8 mm; minimum spot diameter about 0.02 mm; pull load 10–800 N depending on material and joint; laser-on time 0.2–2 s per weld.

Why QCW for precision spot welding

• Low heat input: peak power is 10× the average power.
• Consistent spots from pulse to pulse.
• Small spots with selectable beam quality.
• Maintenance-free fiber laser instead of lamp-pumped YAG.
• Spot welding, seam welding and micro-drilling in one machine.

Typical parts

• Micro sensor housings, diaphragms, leads and terminals.
• Medical stainless steel, titanium and NiTi small parts.
• Copper, aluminum and silver-plated connections (highly reflective metals need sample tests first).

Sample process

1. Send samples or drawings.
2. We select spot size, pulse width and peak power.
3. We weld samples and report appearance, micrographs and pull-test results.
4. Cycle time, fixtures and automation are confirmed.
5. Proposal and quotation.

FAQ

QCW vs YAG laser spot welding?

Both are pulsed. QCW uses a fiber laser: better beam quality, smaller spots, >30% efficiency and no pump lamps to replace.

What is the thinnest material you can weld?

Typically 0.1–0.8 mm; thinner or dissimilar materials need a sample test.

How is it quoted?

By configuration (welding head, fixtures, automation), usually after sample testing.
