Prior to welding thermoplastics, there are a few simple steps that need to be taken to ensure a proper weld. Clean all surfaces , including the welding rod , with MEK or a similar solvent. Groove the substrate large enough to accept the welding rod and then cut the end of the welding rod to a 45° angle. Once the welder has adjusted to the proper temperature, you need to prep the substrate and the welding rod. By using an automatic speed tip a lot of the prep work is done for you.

Whether you need to repair a crack or join pieces of plastic together, welding is the solution. Welding is a relatively simple task to do at home since plastic is so soft and pliable. You need an electric welding gun and an appropriate welding rod to complete the repair.
How to weld plastic?
Use the welding gun’s tip and slowly hover over the plastic for your weld. Begin at the top of the plastic’s cracked area if you are fixing it, or on the area, you are joining. Angle your gun down using a 45-degree angle and touch the nozzle’s edge to the plastic. After that, heat the plastic until it starts to melt.
How to clean plastic welds?
Scrub away all the debris that you can with a sponge. If that isn’t enough, you can also wash the plastic with dish soap. Get rid of any dirt, grease, or other particles that might weaken the weld as you clean your plastic. After your plastic is clean, get a lint-free cloth and dry off your pieces.
What is hot gas welding?
With hot gas welding, you’ll use a plastic welding gun that features a gas heated chamber that passes gas through it to help produce the weld. The gasses used are either dry air or nitrogen. The gas is then heated and used to make the weld.
How to put plastic parts together?

Why is plastic called thermoplastic?
Any plastic you can weld is given the name “thermoplastic.” That’s because that plastic will melt when you heat it to a high temperature, meaning you can also fuse with plastic.
What temperature do you melt plastic at?
Most plastics melt at temperatures between 392 degrees F and 572 degrees F. If you aren’t sure what temperature to set your welding gun at, review the information we gave you above covering that.
What is friction welding?
With friction welding, you use rapid, angled oscillations with the heat while joining the two plastic pieces. Friction welding is similar to spin welding and typically works well when the plastic parts are not symmetrically even. Keep in mind that you’ll have to program your equipment to stop when you join your welds.
How to weld plastic?
Here are the most common methods to weld plastics: 1 Ultrasonic Welding: This method involves re-forming or joining thermoplastics using heat produced from high-frequency acoustic vibration. The process is completed through the conversion of high-frequency electrical energy into high-frequency mechanical motion. In conjunction with other external forces, the mechanical motion produces frictional heat at the welds’ meeting points. The heat generated triggers a molecular bond that enables the welded parts to join. 2 Radio Frequency Welding: This method is similar to ultrasound welding. However, the process uses high-frequency electrical energy or radio waves instead of acoustic vibrations. Radiofrequency welding is among the widely preferred method of welding plastics. The turnaround time for this method is between 2-5 seconds. 3 Hot Air Welding: Commonly referred to as gas welding, this method utilizes hot gas. The hot gas is usually generated once the air in the welding gun has been electrically heated. 4 Laser Welding: Here, two parts of the welds are compressed against each other. A laser beam is then passed across the joining line to form a permanent bond, solidifying the plastic. The turnaround time for this method is 3-5 seconds. 5 Vibration Welding: This procedure relies on friction to produce heat to weld. The parts to be melted or joined are rubbed together under a specific amplitude and frequency to generate friction. Continuous vibrations will eventually generate heat. The heat then melts the thermoplastics at the joint region and cause the pieces to fuse. The turnout time for this process is 1-5 seconds.
How long does it take to weld plastic?
Radiofrequency welding is among the widely preferred method of welding plastics. The turnaround time for this method is between 2-5 seconds. Hot Air Welding: Commonly referred to as gas welding, this method utilizes hot gas. The hot gas is usually generated once the air in the welding gun has been electrically heated.
How to fix a weld that is not smooth enough?
Ensure you fix the weld before it cools completely. If the welded plastic is not smooth enough, add more welding rods. Place your weld in a safe spot, preferably on a heat resistant surface, until it cools off completely. Sand the welded joint: For consistency, smooth out the rough ridges with 12-grit sandpaper.
What temperature to melt PVC?
The recommended temperature for melting PVC is 275 ° C or 527 ° F while that for PE is 265 ° C or 509 ° F.

You can do this by fitting a tack-welding nozzle on the welding gun and apply some heat.
What happens when thermoplastics are heated?
When compatible thermoplastics are subjected to heat, they create a molecular bond that subsequently leads to plastic formation. During production, you have to press the surfaces, subject them to heat and pressure, and then cool off.
