Title: WEAR-RESISTANT WELDING PLATE
Abstract:
The wear-resistant welding plate (1) addresses the issue of the finishing layer (1.3) wear which occurs during welding. Its intended use is for heat welding of thin polymer strips (3.2) and aluminum alloys (3.1) which are used for product packaging (4) in pharmaceutical and other industries. The surface (1.1) of the top welding plate (1) is constructed with a pyramid-shaped engraving which is determined with the dimensions of the pyramid angle (alpha), pyramid front (a) and pyramid interaxial section (b). A NiP (nickel) layer (1.2) is applied to the welding surface (1.1) of the top welding plate and the finishing layer (1.3) made of hard CrN (chrome-nitride) on top of it which due to its wear resistance significantly increases the service life of the top welding plate (1) and in this way prevents the replacement of the top welding plates (1) because of wearing out. The top welding plate (1) can be clamped to the welding machine guides using the elastic base (5) which is adjusted to the surface of the bottom welding plate (2).
