Common Guide for Selecting Heat Gun Welding Nozzles

The welding nozzle (also known as the air nozzle or spray nozzle) of a hot air gun comes in various types, and the choice of the nozzle directly affects the welding accuracy, efficiency and quality. The following are the common types of nozzles and the selection guidelines, explained in conjunction with the application scenarios and the characteristics of the hot air gun:

1.Slot Nozzle

The outlet is conical, with strong air flow focusing ability and concentrated heat. It is suitable for uniform heating over a large area, such as in the welding, preheating or drying of plastic sheets. Different widths of welding nozzles can be selected according to the different welding products.

2.Tubular Nozzle

The outlet is in a straight tube shape, with uniform airflow distribution and an appropriate coverage area. It is suitable for fine welding tasks or local repairs.

3.Speed Nozzle

The welding nozzle is also connected to a small-diameter conical nozzle. If used for welding plastic, guide the appropriate material's welding rod through the nozzle. The welding rod then melts in the weld seam.

4.Special function nozzle

Various forms of welding nozzles specially designed for welding on specific parts are generally custom-made.

Selecting the welding nozzle is the key to efficient welding - choose the appropriate shape based on the material, and select the appropriate nozzle based on the shape. At the same time, it is necessary to match the power of the hot air gun and maintain it regularly to ensure stable airflow. When making a purchase, it is recommended to refer to the compatible nozzle list for the hot air gun model or consult the supplier's adaptation plan.
