The laser beam is generated by exciting a medium with energy, such as a crystal or gas. This excitation produces photons, which are the basic units of light. These photons then travel through a series of mirrors and lenses to be focused into a single, highly concentrated beam.

The laser beam is directed through a series of optics that concentrate the beam into a very small spot size. This tight focus is crucial for delivering high energy density to a precise area, allowing for accurate and controlled welding.

The focused laser beam is aimed at where the two materials must be welded. When the laser beam hits the surface, its energy is absorbed by the material. The absorbed energy causes the material to heat rapidly, eventually reaching its melting point.

As the material heats up, it melts at the point of interaction with the laser beam. The molten material forms a pool or puddle. The molten pool solidifies when the laser beam moves along the joint or seam, creating a welded joint.

Laser welding can be performed in various modes, including pulse, continuous, and pulsed wave. The mode used depends on the specific materials and welding requirements. For instance, pulse mode delivers the laser energy in short bursts. It allows for better control over heat input and minimizing distortion.

One of the key advantages of laser welding is the ability to control the energy input and weld parameters precisely. This control enables the creation of high-quality welds with minimal heat-affected zones and distortion.

Laser welding equipment can be automated using robotic systems. Automation ensures consistent and repeatable weld quality. This makes it suitable for high-volume manufacturing processes.

The success of laser welding depends on factors such as the type of materials being welded, their thickness, and joint design. Some materials absorb laser energy more efficiently than others, impacting the welding process.

Proper heat management is crucial in laser welders to prevent overheating and distortion. Some applications need special cooling techniques to control the heat-affected zone.
