Parameter Guide
Pick a welding method, material, and depth — get recommended laser power, shielding gas, and wire feed speed instantly. Based on the official VL-AC series parameter manual.
Calculator
Three inputs. Instant recommendation. Pure client-side calculation — no signup, no server roundtrip.
Direct fusion without filler wire. Depth 2–6 mm.
Range: 2–6 mm
Methods
Three ways to join metal with a handheld fiber laser. Each has its depth range and ideal use case.
Direct fusion of base metals without filler wire.
DEPTH RANGE
2–6 mm
Scan / wire: 1.0–2.0 mm
Cleanest joint for matching alloys where the base metal itself provides the filler.
Typical Use
Same-alloy sheet joints, thin plate work, cosmetic seams.
Quick spot welds to hold parts in place.
DEPTH RANGE
1–5 mm
Fast, low-energy welds for fixturing before the final pass. Best for alignment and assembly prep.
Typical Use
Holding parts in position, initial assembly, sheet metal layout.
Filler wire (∅1.2 mm) adds material to the joint.
DEPTH RANGE
1–5 mm
Scan / wire: Wire ∅1.2 mm
Use when joining dissimilar alloys, filling gaps, or building up material. Wire is fed automatically by the handheld head.
Typical Use
Gap filling, dissimilar metal joints, build-up repairs.

Best Practices
These recommendations are starting points. Real-world conditions vary.
Real-world materials vary — alloy, surface condition, thickness tolerances. Always verify your settings on a scrap piece from the same batch before welding production parts.
Galvanized steel, aluminum, and titanium produce fumes that require proper extraction. Work in a well-ventilated area or use local exhaust ventilation.
Clean, degreased surfaces give the most consistent results. Remove paint, oil, rust, and oxide layers before welding — especially for aluminum and copper.
These settings are starting points from the ViberLaser VL-AC series parameter manual. Always defer to the official documentation shipped with your specific machine.
