The term welding would conjure images of people holding wand-like tools that are tethered to some machine, or a gas canister. These tools provide enough heat to burn a hole through most metals. An, what’s more, these wands have the power to melt metal and shape it into a desirable form.

Welding do not always mean to involved 10,000 degrees Fahrenheit to bend materials together and may even end up completely destroying the thing that you’re hoping to repair. One of those things is plastic.

Plastic welding is the process of connecting plastic materials with the help of heat to merge them together. When preformed correctly, a strong bond is formed between the plastic and other material. This is useful application for lighter materials as opposed to metal.

However, since they have become an integral part of our lives, it becomes very difficult to operate without them. As such, whenever they break down or tear apart, we know we have to either replace them or make repairs to them. That’s where plastic welding comes in.

In simple terms, the best plastic welder refers to the process of joining together pieces of thermoplastic by introducing, or repairing the molecular bond of those pieces. This process requires some specialized tools for it to be successful.
