Machining VYCOM Hot-gas Welding Hot-gas welding can be performed with a hot air gun and welding rod. The air should be clean and free of all contaminants. If the air is not clean, an inert gas such as nitrogen can be used. The welding temperature and volume of air should be adjustable. The materials to be welded should be free from dust or oil. For butt welding using the hot gas method, sheets should be chamfered using a table saw, milling machine or router. The angle should be 60° for round bends and 80° for triangle bends with corner welds at right angles (Figure 3d). The chamfer should be at 45°. Figure 3d To weld HDPE material, feed the rod through the gun and apply pressure on the rod as the sheet and rod are heated simultaneously. The temperature of the gas should be at 575°F for a round nozzle, and 590°F with a high speed nozzle, when measured 3/16” inside the tip of the gun. The volume of air should be 50 liters per minute using a flow regulator with welding pressure at approximately 2 to 3-1/2 lbs., depending on the rod diameter. Following these guidelines, welding speeds between 11 and 20 inches per minute are possible. NOTE! Skiving off the weld joint for aesthetic purposes will reduce weld strength.
