Welding Machines

Hapco supplies a wide range of welding machines that use heat, pressure, and air to melt two or more objects, combine them into one larger piece, and shape the new piece as desired. Explore our collection of BAK welding machines, made for plastic welding and commercial roofing

Welding Machines Applications

Welding machines are commonly used in the commercial roofing, industrial welding, flooring, oil, gas, and geotextile industries to perform various types of welding jobs such as TPO welding or banner welding. Welding machines can also be used for applications in other settings, such as the manufacturing and automotive industries.

Welding Process

So how do welding machines work? Welding combines the use of a welding rod and a process called heat sealing.

A welding rod is a component that’s inserted between two or more objects and is heated to form a permanent bond. Welding rods with low porosity are most effective because they provide higher quality welds. Welding rods come in various shapes and sizes. Hapco, Inc. offers PE, HDPE, and PVC welding rods.

Heat sealing is the process by which heat and pressure create a permanent seal between two thermoplastics. Thermoplastics are a type of material that can be reheated to take different shapes and serve various purposes over time without incurring severe damage. They are widely used in commercial roofing, and banners, but also in the automobile industry and more.

Top 6 Welding Types

Hot Gas Welding

A type of heat gun called a hot air welder produces a stream of hot air to melt and join two objects.

Speed Tip Welding

After the speed tip component heats and positions the welding rod, it fuses the rod with softened plastic to form a weld.

Freehand Welding

Like hot gas welding, freehand welding also uses a stream of hot air to create a weld. The hot air softens the objects and the welding rod simultaneously to join them together. This is a versatile technique that works for various welding purposes.

Extrusion Welding

The welding rod is inserted into a handheld extruder, transforms into plastic material, and forms a bond between two objects that have been softened by a stream of hot air. This welding type is especially useful for welding relatively thick materials.

Contact Welding

This welding type is almost identical to speed tip welding, the only difference being that contact welding uses thermal conduction rather than electrical conduction. Heated tip components melt and combine two objects by pinching them together.

Hot Plate/Wedge Welding

Two objects are placed on opposite ends of a press while a compatible hot plate or wedge is placed between the objects. Once the objects soften by being pressed against, the hot plate or wedge is removed so the melted objects can form one larger piece.
