Laser Beam Keyhole Welding

Deep penetration laser welding uses a high-power-density laser beam to bore into the material and create a weld. It enables high processing speeds and small aspect ratios.

Physical-Chemical Mechanism of Action

Laser deep welding uses a high-power-density laser that heats the material to a high temperature. This causes local melting and allows a vapor-filled capillary channel to form in the base material.

Metallurgical Relevance & Welding Risks

The high power density of the laser can lead to rapid cooling, which can cause high stress and potential cracking in the weld. Also, focus accuracy can be affected by dust or imperfect material.

Workshop Practice & Instructions

Use a stable laser system with high focus accuracy and controlled cooling. Keep the tool clean and check material quality. Use suitable shielding to minimize the risk of cracking.
