Genuine WE777 WE777 cast iron electrode welding distributor of special cast iron electrode Profile WE777 WE777 WE777 special cast iron electrode in the US R & D Industries factory grades, US industrial equipment 1982 Daxing cast iron production equipment because of prolonged use, storage, operating improper domestic iron causes a lot of equipment with varying degrees of rust, corrosion, cracking, fracture, wear and so on. At the time for cast iron repair difficult, under the background of a bad repair, R & D Industries research efforts WE777 of composition ratio, and focuses on the WE777 iron electrode Piga medicine research and development, add the appropriate amount of rare earth elements to improve the performance of Weld. 2010 by 威欧丁 (Tianjin) Welding Technology Co., Ltd. introduced the Chinese mainland, to the use of WE777 repair of Industrial products in cast iron equipment, successfully WE777 characteristics of cast iron electrode applied to the case of cast iron repair, restoration success stories : cast iron rolls adhesive fracture repair, welding Jichai crack repair cast iron cylinder, cast iron and carbon steel dissimilar welding, cold welding cast iron engine block base and so on. WE777 WE777 special cast iron electrode features a special drug skin effect, the welding process can produce a soft arc similar pulse thermal effects on various types of cast iron base material is very small, special pulsed arc capable of all kinds of cast iron surface to remove impurities, Even for long-term immersion oil and welding of cast iron also has good permeability and porosity does not produce or inclusion, and the hardness of the heat affected zone is not very high, the use of cold welding process of welding seam forming a very Excellent crack resistance, able to respond to a variety of harsh environment of the base material. WE777 special applications for the full range of cast iron welding rod welding cold welding process can weld almost all the cast iron base material and is very easy to implement dissimilar welding of cast iron and steel, to solve such matrix fracture, cracks, wear, fill the hole defects, welding After completely machined, many occasions in the engine casing, cylinder head, the machine base, casting gear teeth and other types of cast iron. Technical parameters of special cast iron welding rod tensile WE777: ≥70,000 PSI (≥482 N / mm2) Yield strength: General 62,000 (≥427 N / mm) Hardness (HB): 185HB and base metal colors: similar power options : AC and DC, DC reverse dc
