How To Weld Cast Iron
Cast iron is not easy to weld and no two pieces are the same. It contains a high carbon content and is about 10 times that of steel. However while difficult you can learn how to Ремонт чугуна by following some general practices. Most cast welding evolves repairs or builds up jobs to castings such as pumps, couplings and the like. By its nature cast iron is brittle and some of the more common repairs are for cracks or broken casings. It can be welded by using stick electrodes such as Lincoln Ferroweld rods and in some cases it can be brazed using bronze filler rods. One of the keys in learning how to weld cast iron is the heat treatment of the material. During the weld process and after the process the casting being worked on must be allowed to cool slowly if pre heating is used to avoid cracking as the weld cools. The other option is to keep the casting as cool as possible so that the rate of cooling is not so important. Heating Cast Iron repairs. The preferred method of re...
