welding-alloys.com 8 Referring to the sketches above, the following methods can be used to successfully create a bend in a WA Composite Wear Plate. Method 1: Making a perforated cut along the proposed bend line with a plasma torch in order to bend the plate through the required angle . Method 2: Removing the hardfacing alongside the proposed bend line by means of gouging to ease bending. After bending, the hardfacing in the gouged area should be rewelded using an appropriate Welding Alloys hardfacing consumable. Information regarding this can be obtained from your local Welding Alloys representative. Method 3: Cutting the part in two following the proposed bend line, and welding it in position using the correct method. Please refer to the following section on Fixing and Assembly. After pre-forming, rolling is much easier. Please note that due to the very high hardness of Welding Alloys composite wear plates, they will damage the surface of rollers. To protect the rollers, a sacrificial plate can be inserted on top of the hardfaced surface during rolling. Due to the high hardness and presence of chromium and complex carbides, equipment used to form, bend and roll Hardplate™ will experience surface damage in the process. e.g., gouge marks on rollers. Pre-forming is best done in a workshop using a conventional brake press which will pre-stretch the sides of the plate to ease rolling. Bending & rolling V 2 1 2 1 1 Stretching
