welding-alloys.com 6 Cutting In the field of thermal cutting, the most economical process to be used to cut Welding Alloys composite wear plates is manual or automatic plasma equipment. For Hardlite™, depending on the length and complexity of the cut, a portable angle grinder may be sufficient for effective cutting. Plasma Principal Plasma systems use the principle of a concentrated electric arc forming a plasma beam that melts the material at very high temperatures. Besides plasma cutting, Laser and waterjet cutting may also be used for more accurate and precise dimensions. These processes are however not as cost effective. When cutting Welding Alloys composite wear plates, it is advisable to first cut all inner shapes before cutting the outside shape. Refer to the illustration above. The product to be cut is a liner plate with an inspection window and six bolt holes. Best practice is to first cut the inspection window and bolt holes, before cutting the liner itself. Recommendations • Use a tool rest or support guide during manual plasma cutting, especially for long or straight cuts, to improve accuracy and reduce operator fatigue. • When possible, pierce from the hardfaced side of the plate. This helps with easier slag removal (flash), although it is more demanding on plasma equipment and may reduce nozzle life. • Always de-burr edges before and after cutting to prevent injury and ensure proper fit-up during installation. • Do not mix offcuts of hardfaced plates with standard construction steel, as they have different material properties and recycling requirements.
