Plastic welding is the ability to take two pieces of plastic and weld them together. This is the type of welding to be performed on children's toys, garden furniture, automobile parts and other types of plastic utensils that you might use everyday or commercial. Types of welds used to join thermoplastics when they are heated and under pressure. Generally the pieces are fused together with a filler material, but some cases do not require a filler material. Plastics often have a shorter lifespan than most types of products because there are so many things that can go into how it is maintained. Elements of nature like cold weather, UV rays of the son or chemical contamination can cause damage to the plastic. Plastics can also receive damage if hit hard like the bumper cars or other hard surface, but the purchase of new parts can be cost prohibitive, this is if it can be a good idea to fix it instead.


There are different types of plastic so it is important to know which ones you work with to ensure that the proper use of welding materials. This is a good idea to understand the difference between thermoplastics and thermosets thermosets can not be welded due. Type of plastic that need improvement will require different welding rod and if you're using the wrong rod to the plastic you need to improve, there will be no ties. Materials such as Polyolefines has a lower surface energy, so this means they can not usually be repaired with a type of adhesive or glue. There is a special group Polyolefine adhesive that can do this job.

When you make improvements in the plastic there are usually two types that you will come up - you'll either have to repair cracks or damaged parts. If you are looking for crack, it means that there are several types of stress that affects the inside of the material you use. This means that you have to fix the cracks and make sure it does not continue through the piece.


There are several types of plastic welding. Some of them are:
  1. Hot gas welding using a welding gun that has an electric heating element in it that generates the heat from the hot gas. 
  2. Hot plate welding using a hot plate between the two surfaces being joined. Ultrasonic welding uses high-frequency acoustic vibrations to weld the pieces together. It was placed under high pressure and then exposed to vibration welding is completed. 
  3. Spins in which the friction welding used to weld the two parts of the cylinder as the parts are played. At any given time stopping the rotation and the weld is complete. 
  4. Vibration welding is required for the plastic pieces and exposing them to a frequency called the amplitude. Two are under pressure which causes friction that generates heat. 
  5. All types of welding work on plastic and they are directed to work with a variety of polymers.
