Laser Beam Welding Theory & Demo
Laser beam welding
Laser beam welding is a technique in manufacturing whereby two or more pieces of material (usually metal) are joined by together through use of a laser beam.
Laser stands for Light Amplification by Stimulated Emission of Radiation.
It is a non-contact process that requires access to the weld zone from one side of the parts being welded.
Advantages Of Laser Welding
• Works with high alloy metals without difficulty
• Can be used in open air
• Can be transmitted over long distances with a minimal loss of power
• Narrow heat affected zone
• No filler metals necessary
• No secondary finishing necessary
• Extremely accurate
• Produces deep and narrow welds
• Low distortion in welds
• High quality welds
• Can weld small, thin components
• No contact with materials
Limitations
• Rapid cooling rate may cause cracking in some metals
• High capital cost for equipment
• Optical surfaces of the laser are easily damaged
• High maintenance costs
