On the slow cooling of wear-resistant welding wire after surfacing
About wear-resistant welding wire slow cooling
In order to prevent the surfacing metal cracks and stripping, surfacing must be slow cooling. Slow cooling method available asbestos or ash, aluminum silicate covered surfacing metal; also with the furnace cooling. For quenching tend to surfacing metal, such as high chromium cast iron wire, tungsten carbide wear-resistant wire, cobalt-based wire. After welding to 600-700 ℃ tempering 1h, then slow cooling to prevent cracks. For the quenching tendency of a small surfacing metal, such as 1Cr13, 2Cr13 welding valve, after welding to obtain higher hardness, air cooling can be used, after the mechanical processing is no longer heat treatment.
