HW Double Wobble Blue Light Hybrid Laser Welding Head 70% Absorption Gap Tolerant

The double wobble blue light hybrid welding head combines a blue laser with a fiber laser in one compact torch. Copper and aluminium absorb blue light at roughly 70%, so the same weld penetration is reached with a far lower total laser power than a red laser setup. Lower power means a smaller source, less chillers load and a clearly lower cost per workstation.

• ~70% absorption rate on copper and aluminium, several times the absorption of fiber laser alone.
• Lower equipment power, lower cost compared with red laser welding of the same thickness.
• Spatter free process with a stable molten pool and a smooth, uniform weld bead appearance.

Two independent wobble axes move the focus spot in X and Y, spreading heat across a wider track. This delivers single side welding with double side forming: one pass from the top produces a full penetration seam with a formed bead on both faces, removing the need to flip the workpiece.

• Wider gap tolerance, wider fit up allowance for stamped and laser cut parts.
• Better weld quality with reduced porosity and crack risk in dissimilar joints.
• Smooth seam appearance that needs little or no post weld grinding.
