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

Welding Process
So how do commercial welders work? BAK hot air welders use a welding process combining the use of a welding rod and a process called heat sealing.
A welding rod is inserted in the automatic welding machine and is heated to form a permanent bond with the material. Welding rods with low porosity are most effective for plastic welding because they provide higher quality welds. Hapco, Inc. industrial welding machines can work with PE, HDPE, and PVC welding rods.
During the heat sealing process using a plastic welding machine, heat and pressure are produced by the hot air welder to create a permanent seal between the two thermoplastics. These automatic welding machines are widely used in commercial roofing, banner & TPO welding, 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. Comparable to hot air welding, this type of welding is common on materials such as thermoplastics such as TPO or PVC.
Speed Tip Welding
After the speed tip component heats and positions the welding rod, it fuses the rod with softened plastic to form an efficient weld. This type of welding can be used by using a heat gun.
Freehand Welding
Like hot air 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.
