Technocoat TL-series (TL-50/100/200) pulsed laser overlay/ laser welding equipment

Pulse Spot Irradiation
The overlay material melts instantly and bonds with the base material using a low heat input. This process enables high-quality overlay welding without adverse heat effects, such as distortion or undercutting.

Minimizing Failures like Pinholes and Porosity
Argon gas shielding prevents oxidation in the overlay area, ensuring a higher quality overlay.

Minimizing Overlay Material Usage
Narrow grooves, hole bottoms, side faces, inner faces, and inside corner fillets can be welded effectively without the need for pre-heating or post-heating.

Applicable to Various Steel Types and Dissimilar Metals
Suitable for overlay welding on most steels, including aluminum, titanium, copper alloys, stainless steel (SUS), gold, and even dissimilar metal combinations.

Laser Welding

Advantages:

Easy operation

Low heat input

Enables precise overlay welding (Reduces finishing time & cost)

Can perform overlay welding in narrow grooves, bottom holes, side faces, inner surfaces, on overlay joints, or inside corners

No need for pre-heating or post-heating

Disadvantages:

Slow overlay process for large areas

Argon Arc Welding (TIG)

Advantages:

Quick overlay

Easy to operate on-site

Disadvantages:

High-skill to operate

High-heat input (Prone to distortion and stress)

Undercut formation

Requires a larger amount of overlay material (Increases finishing time & cost)

Difficult to perform overlay welding in narrow grooves, bottom holes, or side faces
