What is Hot Air Weld Gun?

A hot air weld gun, also known as a hot air welder or a heat gun, is a tool that is commonly used in the welding and fabrication of plastic materials.

The hot air weld gun works by heating up the plastic material with a stream of hot air, which softens and melts the plastic. The softened plastic can then be welded together or bonded to another piece of plastic, creating a strong and durable joint.

Hot air weld guns are used in a variety of industries, including automotive repair, construction, and manufacturing. They can be used to weld a variety of plastic materials, including PVC, polypropylene, polyethylene(PP), and many others.

Hot air weld guns come in different sizes and shapes, with varying temperature and airflow settings, allowing for precise control over the welding process. They are also relatively easy to use and maintain, making them a popular choice for professionals and DIY enthusiasts alike.

How to weld the polypropylene sheet?

Welding polypropylene sheets can be accomplished through a process known as "hot gas welding." Here are the steps to weld PP sheets using this method:

Prepare the surfaces: Clean the surfaces that will be welded thoroughly. Ensure that there are no contaminants, debris, or oils present. You can use a cleaner designed for polypropylene or isopropyl alcohol.

Mark the weld line: Use a marker to draw a line where the welding will occur.

Preheat the PP sheets: Use a hot air gun to preheat both sheet along the weld line. The temperature should be around 240-260°C. Preheating helps to soften the polypropylene and prepare it for welding.

Weld the sheets: Once the polypropylene sheets are preheated, use a plastic welding rod that matches the material of the sheets. The rod is melted by a hot air gun and used to fill the gap between the two sheets. The gun and rod are moved along the weld line at a steady pace until the sheets are welded together. Ensure that the melted rod is evenly distributed, and there are no gaps.


Cool the PP sheets: After welding, allow the PP sheets to cool down gradually. Do not cool them rapidly as this can cause warping or cracking.

Trim excess plastic: Once the PP sheets have cooled down, any excess plastic that has accumulated along the weld line can be trimmed using a sharp knife or a rotary tool.

Hot gas welding can be a delicate process and requires some practice. If you are unsure about performing this process, it's recommended to consult a professional or take a training course.
