Play Video

The Koolaser Handheld Laser Welder operates using advanced semiconductor laser technology, which is at the heart of its precision welding capabilities. Below is a step-by-step breakdown of how the welder functions, particularly in the context of welding thin metal plates ranging from 0.1mm to 2mm in thickness.

1. Laser Generation

The core of the Koolaser welder is its semiconductor laser, also known as a diode laser. In this system, a semiconductor material (such as gallium arsenide) is used as the laser medium. When electrical current is applied to this material, electrons are excited to higher energy states. As these electrons return to their lower energy states, they release energy in the form of photons, creating a coherent laser beam.

The laser produced has a wavelength of 915nm, which is particularly effective for welding metals due to its efficient absorption by the material, resulting in effective energy transfer.

2. Beam Focusing and Control

Once generated, the laser beam is directed through a series of optical lenses that focus the beam into a fine spot. This focused spot, typically just a few micrometers in diameter, is precisely controlled to ensure accurate placement on the workpiece.

3. Welding Process

The focused laser beam is directed onto the surface of the metal plate to be welded. The high-intensity light rapidly heats the material at the focal point, causing it to melt and form a molten pool. As the laser moves along the weld path, the molten metal solidifies, creating a strong, continuous weld. 

The Koolaser handheld welder supports multiple operating modes:

  • Continuous Mode: The laser emits a steady, uninterrupted beam, ideal for creating long, uniform welds. This mode is often used when welding thicker sections of the thin plates.
  • Pulse Mode: The laser emits energy in controlled bursts, which is beneficial when welding very thin materials or when precise heat management is required to prevent distortion.
  • PWM Mode (Pulse Width Modulation): This mode allows for fine-tuned control over the duration and frequency of the laser pulses, making it versatile for various materials and thicknesses.

The ability to switch between these modes provides flexibility and precision, ensuring optimal results for different welding tasks.

4. Cooling System

Given the high energy involved in laser welding, effective cooling is essential to maintain the system’s stability and prevent overheating. The Koolaser welder employs a water cooling system that uses pure water as a medium. 

This system circulates water through the laser and critical components, dissipating heat and ensuring that the device operates within its optimal temperature range (25°C to 40°C).

The cooling system not only protects the laser from thermal damage but also contributes to consistent laser output, which is crucial for achieving uniform welds, especially on thin plates where precision is key.

5. Safety Mechanisms and Visual Positioning

Safety is a critical aspect of operating high-powered laser equipment. The Koolaser handheld welder is equipped with several safety features:

  • Red Dot Visual Positioning: This feature projects a red dot onto the workpiece, helping the operator align the laser precisely before welding. This visual aid is particularly useful when working with small or intricate parts.
  • Safety Locking Clamp: Ensures that the laser will only emit when the welding gun is in proper contact with the workpiece, preventing accidental exposure to the laser beam.
  • Grounding and Electrical Safety: The welder must be properly grounded to avoid electrical hazards. This is especially important in industrial environments where the equipment is used regularly.

6. Final Weld Quality

The combination of semiconductor laser technology, precise beam focusing, and robust cooling results in welds that are of exceptionally high quality. The welds produced by the Koolaser handheld welder are characterized by:

  • Minimal Thermal Distortion: The focused laser energy ensures that only the targeted area is heated, reducing the risk of warping or deformation of the thin plates.
  • Strong, Clean Joints: The rapid melting and solidification process creates strong, uniform welds that require little to no post-weld processing.
  • High Precision: The fine control over the laser beam allows for intricate weld patterns, making the Koolaser welder ideal for applications where precision is paramount.
