Transmission Welding: Reasons Why You Should Choose it

Transmission welding, also known as laser transmission welding, refers to the process of bonding thermoplastics using focused laser radiation. Laser transmission welding has become the technology of choice, especially when applications involve components which require high-quality welds. The process of laser welding is very distinct from other traditional methods and techniques of welding.  Here is what you need to know about this technology and why you should choose it for your industrial welding needs.

What transmission welding entails

The technology of transmission welding joins two plastic materials: an upper joining partner and a lower joining partner. A focused laser beam is passed through the upper joining partner to hit the targeted welding zone. As it hits the lower adjoining partner, it converts into heat energy. The heat created at the interface creates a molten weld seam, and the two plastics are fused.

Applications of transmission welding

Transmission welding has become popular among manufacturing companies as it can be applied across most industries that make use of plastics. It is possible to weld almost all types of thermoplastics as long as they have the same melting or softening temperature ranges. It becomes even easier if the plastics have the same chemical makeup. The technology has been widely applied in the following industries:

  • The automotive industry in the manufacture of sensor housings, lighting, instrument clusters, interior panels, and fluid control devices.
  • The medical industry in catheters, microfluidics, and fluid control.
  • The manufacturing industry in the manufacture of consumer products such as electronics.

Advantages over traditional welding methods

All of the methods of welding plastics have their strengths and downsides. The cost of modern laser welding equipment and systems is almost similar to that of traditional welding methods such as hot plate, vibration, and spin. However, transmission technology takes the upper hand when it comes to efficiency, consumables cost, and production precision. It has the following advantages:

  • There is minimal mechanical stress on the welding and components, making it possible to utilize simple clamping equipment and holders. With this, the economic flow is achieved, hence resulting in reduced costs of production.
  • Laser systems can identify irregularities during the welding process, facilitating the production of high quality and durable welds.
  • Unlike traditional welding methods, no additives are added to the components. As a result, welding using this technology satisfies even the most precise optical specifications.
  • Transmission welding systems have a high degree of flexibility and integrated process control. As such, project-specific costs are reduced as the system can adapt to different project requirements.

Transmission technology is slowly dominating the welding industry. Compared to traditional welding methods, this technology delivers high-quality welds and enhances flexibility, and versatility in operations.
