Laser Welding Machine Working Principles

Using a laser beam, a laser welder can join together micro-plastics.The laser beam does not scatter like light bulb light, and it is directed in parallel in the same direction. A laser beam has a high energy density as a result of this. So, high energy can be obtained by focusing the parallel light on a single point using a lens. This energy is used in the welding process. What it's all about is the theory that electrons can be excited by taking in energy. It then decays to its ground state and emits a light photon. Stimulated radiation emission increased photon concentration, resulting in a high-energy laser beam.

What is a Laser Welder?

A laser welder is designed to solder and weld plastic with the help of a laser beam.

• It is possible to join micro components and objects that require a lot of force without touching them.
• It is easy to link materials with high electrical conductivity.
• The laser beam has a high energy density because it is emitted in the same direction in parallel without being scattered like light from a lamp bulb. Furthermore, high energy can be obtained by focusing the parallel light on a single point.
• Laser welding equipment that uses such energy is helpful in soldering and plastic welding.

What is Laser?

Radiation emitted in response to a stimulus is amplified. Lasers can produce a highly focused beam of radiation by inducing and amplifying specific wavelengths of light from atoms or molecules. Only a tiny portion of the visible or ultraviolet spectrum is typically emitted.

How Do Laser Welding Work?

Metal and thermoplastics can join using laser welding.The beam's focus allows for narrow, deep welds and high welding rates. It's commonly used in high-volume, automated applications like the auto industry. It welds in keyhole or penetration mode. Only the material's surface absorbs the laser beam, which does not pass through it. These welds often have a high width-to-depth ratio because they are limited in their ability to conduct. Through a keyhole mechanism, higher power densities can be achieved with laser welding. Welding with a laser beam is fundamentally straightforward: two precisely cut sheets are joined together with a laser beam. This will melts the edges of the sheet metal. The melt flows into each other, resulting in a fully functional joint.

Types of Lasers Used

• Gas lasers:

This laser is a mixture of gases, such as nitrogen, helium, and carbon dioxide, which make up the lasing medium.

• Solid-state lasers:

Solid-state laser materials include glass and neodymium-doped yttrium aluminum garnet. Another option is synthetic ruby crystal (made from chromium oxide in aluminum oxide).

• Fiber laser:

Optical fiber is used as the lasing medium in a fiber laser.

Types of Lasers Used in Welding & Cutting

Laser welding machines commonly use gas, solid-state, and fiber lasers. Optical fibers are widely used to produce the laser welding machine's laser beam. There are single fiber welding machines and multi-fiber welding machines to choose between. Carbon dioxide lasers (CO2) or neodymium-doped yttrium aluminum garnet lasers are the most commonly used for laser cutting and welding. Other laser cuttings and welding machines are available.

Basic Configuration of Laser Welder

The laser beam produced by the laser oscillator is guided to a distant place by an optical fiber and focused into a single fine spot by a lens for material fabrication.

FAQ:

How does a laser weld machine work?

Laser welding is joining metals or thermoplastics together to form a weld. Laser welding can weld thin materials at high speeds due to the concentrated heat source. Laser welding is a simple process that joins two precisely cut sheets. The laser melts the sheet metal edges. The melt flows into each other to shape the joint.

What gas is used in laser welding?

Helium and argon are the most commonly used shielding gases for laser welding steels. In laser beam welding using a penetration mode, helium has significantly greater penetration than argon. As an alternative to these inert gases, carbon dioxide has been floated.

Which type of energy is used in laser beam welding?

A continuous-wave or pulsed output of photons can be used for laser welding. The laser beam is always on with CW systems during welding. Pulsed systems modulate their work to produce a series of pulses with a pause between each pulse.

How does laser beam welding generate heat?

A high-intensity laser beam is used to generate heat at the weldment. The work piece's surfaces melt and become bonded together with a small weld zone and HAZ.
