We thought we would take a little break here from our usual molding and plastic talk and instead discuss laser welding.
Laser welding services or laser beam welding (LBW) is a technique that is used to join several pieces of metal by employing a laser. The laser beam creates a concentrated heat source which allows for very narrow and deep welds and high a high welding rate. Laser welding is often used in high volume applications.
In case you did not know it, LASER is an acronym for “Light Amplification by the Stimulated Emission of Radiation”.
Welds created by laser welding are much stronger than conventional welds. Industries that may use laser welding include
- jewelry repair
- medial device dental
Benefits of laser welding include
- Processes high-alloy metals
- open air use
- long distances with a minimal loss of power
- Low total thermal input
- Welds different metals
- No filler metals needed
- No secondary finishing is needed
- Highly accurate
- Welds high-alloy metals
Disadvantages of laser welding include
- Cools quickly which may cause cracks
- Optical surfaces may be damaged
- High maintenance cost
Comparison to Other Welding Processes
Similar to Gas Tungsten Arc Welding, laser welding is a fusion process performed under inert cover gas, where filler material is most times not added. Similar to electron beam welding, laser welding is a high energy density beam process. Laser cutting is different from both GTAW and EB or electron beam welding , because it does not need the workpiece complete an electrical circuit. Because electron beam welding must be performed inside a vacuum chamber, laser welding may offer a cost advantage over electron beam welding.
