Basic requirements for plastic welding. TIME, TEMPERATURE & PRESSURE

Most plastics used today are thermoplastics, which are generally suitable for
repair by welding.

Four basic rules for plastic welding are suggested:

1. Weld with like material.

Only like materials can be welded, i.e. PP with PP.

2. Correct temperature. The plastic should be pre-heated. Select the right
temperature matched to the material being repaired.

3. Even pressure.

When welding with rods, the pressure is applied by
pressing on the welding rod. For overlap welding of films and tarpaulins, the
necessary pressure is applied with the help of the optional pressure roller.

4. Constant welding speed. To achieve a good weld, an even working
speed should be maintained. When welding plastics with the Master
Proheat, the following three variables are critical to achieve a good weld.

TIME, TEMPERATURE & PRESSURE

• Time. If you move the heat tool too fast or too slow, the quality of the weld

will be compromised. Maintain constant speed during the welding process.

• Temperature. Set the welding temperature for the plastic that you are
welding. Adjust the temperature and airflow to obtain the best setting
combination for the plastic you are working with. Locking-in the setting
enables you to maintain the set temperature throughout the welding pro­cess. The Master Proheat Model PH-1400 has the ability to tightly control
and lock-in the temperature through an on-board electronically controlled
temperature and air speed system. See the heat gun instruction manual
on how to lock-in settings.

• Pressure. Pressure is applied by pushing down on the welding rod while
welding or, if butt welding, on the two edges that are being overlap welded
together. Master Appliance Corp. manufactures precise welding tips that
help the welder apply equal pressure throughout the welding process.

Thermoplastic welding temperatures.

There are different types of plastic so it is important to identify the type you are
working on in order to make sure that the proper welding rod is used. Thermo­plastics can be formed with heat and retain their shape after cooling and can be
easily welded. Thermosets (Duroplastics and Elastomers) cannot be welded.
Duroplastics are hardened with heat and their shape cannot be changed with
heat. Elastomers (rubber) can be formed with heat but cannot be welded.
