Laser Welding Machine

The ±0.05mm positioning accuracy, combined with a continuously adjustable spot diameter of 0.2–2mm, allows operators to target exact weld locations on micro-components. The red-light aiming system confirms placement before firing, which is essential when working on parts where even slight misalignment causes rejects — battery electrode connections, eyeglass hinge joints, or sensor diaphragm seals.

The DSP microcomputer accepts spot, linear, circular, elliptical, arc, and rectangular weld paths. Once a program is stored, operators can recall it for batch production without re-teaching. This reduces per-part cycle time significantly when welding repetitive features such as circumferential seams on pipe fittings or multi-point tack patterns on stamped assemblies.

Pulse width adjustment from 0.3ms to 25ms and frequency control from 0 to 100Hz let operators match energy delivery to material thickness and thermal sensitivity. Short, high-energy pulses minimize distortion on thin stainless-steel cups or aluminum housings; longer pulses provide deeper penetration on thicker copper bus bars or alloy valve bodies.

The dedicated water-cooling unit maintains consistent laser cavity temperature during extended production runs. Stable thermal conditions prevent power drift, so the first weld of a batch and the last weld maintain the same penetration depth and bead profile — a measurable quality advantage over air-cooled systems that derate during sustained use.

At 6kW rated power on single-phase 220V supply, this machine fits into existing production lines without electrical upgrades. The modular layout — separate control cabinet, chiller, and work station — allows flexible floor-plan arrangement and straightforward maintenance access to each subsystem.
