One-Day Plastics Welding Course

"The Course was great. Exactly what my staff and I needed to fast track our understanding of the Plastic Welding technology. I am much more comfortable with my knowledge of the process and realizing my colleague was a bit of a natural at it helps me know we will be successful. Thanks to Matt for his patience teaching us and to Anthony for arranging the course for us." -Brandon Jewitt, General Manager, On the Water Designs

WELDPLAST vs. FUSION – What’s the difference between these Leister extrusion welders?
Leister manufactures two different series of extrusion welders: WELDPLAST and FUSION. Find out about their differences and advantages. ​

​Finding the Correct Welding Temperature for your Plastic Welding Project
Every plastic has a set of parameters (temperature, pressure, time/speed) at which it should be welded. However, the perfect temperature for the application can vary depending on environmental conditions. If you are welding in a less than ideal environment, the only way to find the perfect welding temperature for your project is trial and error. If welding is taking place outdoors be sure to perform test welds periodically throughout the day to ensure your temperature is set correctly, as the environment can change over time.

Tutorial: Evaluating your Plastic Welds
​It’s important to evaluate each plastic weld to ensure your final product is strong and resilient. Particularly when speed welding with a hand tool, small defects in a single weld can be magnified as beads are built up to the base material’s thickness. Several key indicators allow you to evaluate your welds without the need for destructive tests.  

Choosing the Right Tool for your next Plastic Welding Project
Broadly, there are two types of hot air plastic welding tools: manual tools and extrusion welders. Manual tools are ideal for very small fabrication work, detailed projects, and repair work. Extrusion welders are suited for larger fabrication projects such as tanks, chutes, liners, and piping. 

Identifying Plastics for Fabrication and Repair
It's important to identify the plastic you're welding as only like plastics can be joined. The simplest way is by performing a burn test. Learn what properties to look for and how they can tell you the plastic type of your material.
