How To Weld Plastic?
Plastic welding is a mechanical process that includes joining of two pieces of plastic with each other by means of welding. It is more economic to repair the plastic than buying the new one. Plastic welding is a tedious process, but you can do it easily by following some simple tips of welding. This article will provide you some easy instruction to weld the plastics.
Advantages of plastic welding
Expensive plastic components can be repaired easily by using “Leister 100.726 electric welding tool”. Almost all of the modern motor vehicles possess some components that are manufactured from the plastic, for example- grilles, bumpers, light covers etc. In general, these components are extremely expensive, so one can’t afford to renew the components after a light damage. Plastic welding is a great help in repairing these components.
If you are following a right procedure then welding of the plastic components doesn’t produce any fumes. No special treatments (fillers) are required in repair/welding of the plastic. Moreover, you can provide a brand new look to your damaged plastic components by following right welding and by using appropriate “after paints”.
Majority of the plastic components that are used in the automobile industry are thermoplastics. So, after appropriate heating (softening) these plastics can be easily welded or molded. Plastic components that are marked as PP/EPDM and ABS are extremely easy to weld.
Materials required for plastic welding-
Welding gun (Leister 100.726 electric welding tool), damaged plastic component, welder Rod, Sandpaper (80 and 150 grit) and foil tape.
Easy instructions for welding the plastic components-
Step 1- Locate the damaged part of a plastic component. If it is possible to dismantle the component from other parts of vehicle then do it, otherwise you can work as it is. Thoroughly, clean the damaged parts of the component by using a light solvent degreaser or by using simple soap/detergent water.
Step 2- Now; sand the damaged part/portion of the plastic component, using a sandpaper of 80 grits. And then simply join the damaged pats with each other by using a foil tape.
Step 3- Preheat the welding gun for 20 minutes. You should be aware about the type of plastic on which you are working, because use of a particular temperature depends upon the type of the plastic. Usually, the temperature ranges between 510 to 550 degrees F. For achieving the appropriate temperature, move the tip of welding gun towards or away from the plastic component.
Step 4- Now; insert the damaged plastic and welding rod in the preheated welder. Move the applicator tip along the crack/joint, maintain the steady motion. You should allow enough time for proper repairing. Welding rod should be made from the appropriate material.
Step 5- Now finish the repair by sanding the repaired joint with the sandpaper having 150 grit. And then finish the process by covering the plastic component with some water based solvent.
You should never hold the welding gun at one spot of the plastic for too long, as this will burn the plastic.
