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.
Can lasers be used to weld plastic?
Laser plastic welding, also often referred to as through-transmission welding, is a process of bonding plastic using focused laser radiation. The process is very much different than traditional metal welding.
What is plastic welding used for?
Included in most plastic welding processes are devices that hold the plastics components together so that a complete bond can be formed as the heat is added to the weld joint. Plastics welding is used for the joining of plastics pieces but also to repair cracks.
Can laser melt plastic?
In plastics materials such as polypropylene, the 10.6µm wavelength of the CO 2 laser is completely absorbed in a less than 1mm of material. These lasers are capable of melting such plastics at very high speeds to produce lap welds.
Why laser welding is used only for micro welding applications?
Micro welding is just as it sounds – welding on a very small scale. There are different types of systems that perform micro welding: arc welding, plasma welding, and laser welding to name a few. Laser Dynamics uses lasers for our micro welding services because they are precise, repeatable, economical and scalable.
What industries use laser welding?
The aerospace, military and defense, electronics, lab research, medical and petrochemical industries use laser welding because it is a fast process that offers minimized heat input and deep penetration abilities.
How does laser welding work?
Welding by laser beam is basically very simple: Two precisely cut sheets are held together. The laser melts the edges of the sheet metal. The melt flows into each other – and the joint is complete.
How does an ultrasonic welder work?
Ultrasonic welding uses ultrasonic energy at high frequencies (20–40 kHz) to produce low amplitude (1–25 μm) mechanical vibrations. The vibrations generate heat at the joint interface of the parts being welded, resulting in melting of the thermoplastic materials and weld formation after cooling.
What is example of plastic welding?
Electric resistance welding such as spot welding is an example of plastic welding. In fusion welding, the metal at the joint is heated to the molten state. Then it is allowed to solidify. Pressure is not applied in this welding process.

Can a laser melt rock?
Modern high power lasers have enough power to spall melt and vaporize all types of rocks.
Can you laser etch PETG?
So, can you laser cut PETG? Yes, you can laser cut PETG, but it is a dirty material to process, giving off a significant volume of white particulates. Your laser machine will need regular cleaning and fume extraction filters will soon clog up unless you have a sacrificial pre-filter to take the strain.
What is transparent laser plastic welding?
Transparent Laser Plastic Welding. It is a misconception that laser welding plastics requires one clear part and one opaque part. It is perfectly possible to weld opaque-to-opaque as well as clear-to-clear. There are multiple ways to weld two clear polymers with laser. One method makes use of a special, optically clear chemical called Clearweld.
What is the laser welding practical book?
As such, it provides comprehensive information on material and process characteristics as well as applications regarding plastic laser welding. The first part of this practical book introduces the structure and physical … Show all
Can You weld two clear polymers with laser welding?
It is a misconception that laser welding plastics requires one clear part and one opaque part. It is perfectly possible to weld opaque-to-opaque as well as clear-to-clear. There are multiple ways to weld two clear polymers with laser. One method makes use of a special, optically clear chemical called Clearweld.
How does laser welding work on plastic?
When laser welding plastics using the transmission welding method, two types of thermoplastics are joined with one another: the laser passes through the transparent mating part and the absorbing mating part is heated. The absorbing plastic melts the transparent joining area.
