A heat welding apparatus for bonding a heat-meltable sheet, such as an asphalt sheet, to a substrate. The apparatus has a chamber having an inlet and an outlet on opposite sides thereof and an exhaust duct in its upper portion for exhausting gases generated during welding, a conveyor mechanism extending through the inlet and outlet of the chamber for intermittently conveying a laminated structure of the substrate and the heat-meltable sheet, and near infrared radiators for heating the laminated structure disposed respectively above and below the laminated structure which has been fed into the chamber, and stopped thereat, by the conveyor mechanism.
