How To Do Plastic Welding

Now that you’ve done your research and gathered your plastic welding supplies, it’s time to get started!

The process of plastic welding can be broken down into three general steps: surface preparation, heating/melting the plastic together and finishing. Let’s go over each step in more detail.

Surface Preparation

Before starting plastic welding, make sure both surfaces are clean and free from dust or debris. It is extremely important that both pieces fit snugly against each other for a strong bond. If the edges don’t fit tightly, use a file or sandpaper to even them out so they come together smoothly.

Heating & Melting

Once everything is ready to go, it’s time to heat up the plastic. Different plastic materials may require different amounts of heat, so make sure you know the melting point of your plastic so you don’t overheat it. Some plastic welding tools come with temperature controls that allow you to adjust the heat level as needed. When you’re ready, apply an even amount of pressure to both surfaces and hold them together for several seconds until they melt and seal together.


Once everything has been melted together, it’s time to finish up the welding process. Depending on what type of plastic you are using and how strong of a bond you need, there are various methods for finishing off plastic welds. You can use specialized plastic welding tools or other hand tools such as files or sandpaper to smooth down any sharp edges that may remain after welding. You can also use plastic filler material to add strength and durability to the weld if needed.


Now you know how to plastic weld! With practice, plastic welding can become a very useful skill for all sorts of projects. Plus, it’s an affordable option compared to many other types of plastic fabrication methods. To learn more about plastic welding, check out GA Profiplast.
