OVERVIEW
Laser Beam Welding (LBW) is a welding process in which a high-energy laser beam generates heat specifically on the workpiece. The laser beam heats and melts the edges of the workpiece, forming a joint.
In laser welding (LBM), the connection is made as either a series of overlap spot welds or a continuous weld seam. Laser welding is used in the electronics, communications, and aerospace industries to manufacture medical and scientific devices for joining small components.
Working…
Laser beam welding works on the principle that the electrons of an atom are excited by receiving some energy. Then, after a while, when it returns to the ground state, it emits photons.
The concentration of this emitted photon is increased by stimulated emission of radiation, resulting in a highly energetic focused laser beam. The amplification of light by stimulated emission of radiation is called a laser.
Activates the machine’s flashlights and emits photons. The energy of photons is absorbed by the atoms of the ruby crystal and the electrons are excited to higher energy levels. When they return to low energy or ground state, they emit photons.
The photon of this light then excites the electron in the atom, producing two photons. This process continues, resulting in a focused laser beam used to weld multiple parts at the desired location.

APPLICATIONS
- It is noticeable in the car industry. Therefore, mass production is used for areas that need to be produced.
- It is used for high precision welding. Because there is no electrode, the last welding is easy, but it is strong.
- Laser welding is also often used for jewelry production.
- Laser beam welding is used in the medical industry to bring metals together on a small scale.
MATERIALS
Materials that the laser welding machine can weld are;
- Die steel. The laser welding machine can be used to weld S136, SKD-11, NAK80, 8407, 718, 738, H13, P20, W302, 2344 and other types of die steel, and the welding effect is better
- Carbon Steel
- Alloy Steel
- Stainless Steel
- Copper and Copper Alloy
- Aluminum and aluminum alloy
DESIGN CONSIDERATIONS
There are restrictions on the welding thickness. As such the site of welding on the work material should not be less than 2mm and not greater than 19mm.
POST PROCESSING
- General Post Processing involves Dry testing (Weld seam test for breaks and Welded joint strength) & Deburring.
- Electroplating, Anodising, Chemical treatment, Powder Coating, or Painting can be provided based on the requirements provided.
FAQs
Frequently Asked Questions
Laser welding offers numerous benefits:
- High precision with minimal heat distortion.
- Deep weld penetration with a small heat-affected zone.
- Suitable for dissimilar metals.
- Clean and smooth welds, often requiring no post-weld processing.
- High welding speeds.
Many metals and thermoplastics can be laser welded, including:
- Stainless steel, aluminum, titanium, and gold.
- Certain plastics like polycarbonate and ABS.
Software like SolidWorks, AutoCAD, and proprietary software specific to the laser welding equipment can be used.
To complement laser welding, we offer:
Laser cutting and engraving.
Surface treatments and finishing.
Inspection and quality control.
Assembly services.
Laser welding is more precise, offers deeper penetration with a smaller heat-affected zone, and is often faster than traditional welding methods. It’s especially suitable for intricate designs and delicate materials.
While laser welding can handle a range of thicknesses, extremely thick materials might require multiple passes or be better suited to traditional welding techniques.
