Laser Beam Welding (52 / LBW)
The World of Laser Welding
Highest energy density, extremely narrow seams, and a minimal heat-affected zone (HAZ). The gold standard for distortion-free results, micro-welding, and mass production.
Laser Process & Focus Calculator
Simulate the welding mode based on laser power (watts) and focal diameter.
Laser power (P):2000 W
Focal diameter (d_f):0.2 mm
Calculated Power Density:6.37 MW/cm²
Deep Welding (Keyhole / Steam Capillary)Extreme burn-in
Power density ≥ 10^6 W/cm²! The material vaporizes in localized areas, forming a vapor capillary and producing extremely deep, narrow seams.
⚠️ Gap Tolerance (Zero-Gap Rule)
Laser beam welding without filler wire requires gap widths of ≤ 0.05 mm! With wider gaps, the molten metal sags—creating a risk of cold welds.
