How Does a Handheld Metal Laser Welding Machine Work?
A handheld laser welder operates by emitting a high-energy laser beam onto the metal surface, which rapidly heats and melts the material at the focal point. The molten pool quickly solidifies, creating a strong metallurgical bond between the parts.
Process Highlights:
-
Laser Generation: Diode, fiber, or Nd:YAG lasers are commonly used depending on the model and metal type.
-
Beam Delivery: The laser beam is delivered through optical fibers or articulated arms to the handheld welding gun.
-
Welding Control: Operators adjust laser power, pulse duration, and frequency to match metal thickness and type.
-
Cooling System: Integrated cooling prevents overheating of both the laser source and the welded components.
Key Applications of Handheld Metal Laser Welding Machines
These machines serve vital roles in many sectors due to their adaptability and precision:
-
Automotive: Repair and assembly of body panels, engine components, and exhaust systems
