Key Considerations for Laser Welding Robots
1. The Good Fits-up: Demands on Prior Processes
Laser welding is often the last critical step—like assembling a watch case. If part dimensions are inaccurate, even the finest laser cannot create a perfect seam.
Example: Welding two enclosures with misaligned edges due to imprecise bending is like trying to zip up a jacket with misaligned teeth—the beam may miss the joint entirely.
Requirement: Part fit-up accuracy typically must be under 0.2 mm—demanding near perfect cutting, bending, or stamping beforehand.
2. The Core "Light Needle" vs. Gap Dilemma
The laser beam is an extremely fine “light needle,” excelling at fusing tightly mated joints. For autogenous welding, the gap is recommended under 0.2 mm. For wire-fed welding, gap tolerance is slightly higher but strictly governed:
Thick plate (>1mm): Gap should ideally be ≤ half the plate thickness.
Thin plate (<1mm): The smaller the gap, the better; otherwise, high-power wire filling easily causes burn-through.
General Limit: Wire diameter and weld bead width typically should not exceed 1.6 mm.
3. Jigs and Fixtures
Increased surface roughness: Insufficient precision can cause the laser focus position to shift, leading to uneven energy distribution and resulting in burrs and slag on the cut surface.
4. “High Repeatability”-- Robotic Accuracy
The robot must possess high repeatability, typically within ±0.02mm, ensuring each welding path is perfectly replicated. This enables zero-defect consistency in high-volume production.
We use top robots (Yaskawa, ABB, FANUC) to achieve micron-level precision, ensuring consistent, high-quality welds
