What is Laser Welding ?

Views: 7     Author: Site Editor     Publish Time: 2022-12-28      Origin: Site

Laser welding utilizes a laser beam as a concentrated heat source to join multiple pieces together. Delivering a focused heat source, laser welding creates a strong seam at a high speed.

The processes and applications of laser welding are most prominent in the automotive industry, where lasers boost productivity at a low cost when welding automotive parts – such as roof , door or filter assemblies – together.

However, laser welding is also often used in the jewelry and medical industries to put together metals on a smaller level. Any material with a high heat conductivity can be laser welded, whether it’s for an automobile or a small medical/jewelry item. Laser welding is also frequently used in high capacity manufacturing in the medical and automotive industries.


Any thermoplastic is a candidate for laser welding to itself.  
  • For transmision welding: Must have one transparent part and one opaque part

  • For dissimilar thermoplastics: Melting temperatures should have a 50° C overlap range. Allows for melting phase (between solid and decomposition phases) to be compatible
