What is Keyhole Welding?

Keyhole welding is a fusion welding technique that employs a concentrated energy beam, often generated by laser or electron beam equipment. This method creates a keyhole-shaped molten pool that penetrates the materials being joined, resulting in high-quality welds with minimal heat input. The keyhole serves as a conduit for the energy, allowing for deeper penetration and faster welding speeds compared to traditional methods.

How Does Keyhole Welding Work?

The process begins with the generation of a focused energy beam directed at the joint between two workpieces. As the beam strikes the surface, it melts a small area of the material, forming a keyhole. The keyhole acts as a reservoir for the molten metal, allowing the energy to penetrate deeply into the base materials. The surrounding material heats up, aiding in the welding process, while the keyhole shape ensures that the weld pool stays concentrated and stable.
