Profile: Cast Iron Welding Services Limited specializes in the gas fusion weld repair of cast iron components. We are also specialized in various casting in the form of architectural, steam and vintage vehicle components. We deal with numerous problems such as mechanical damage, fractures, erosion and cracks. Gas fusion welding of cast iron ensures a homogeneous stress free weld repair with improved metallurgical and machining properties compared to those of the parent metal. All castings are pre-heated at a controlled rate until the optimum welding temperature is reached. Weld repairs to cast iron components include cast iron cylinder heads, engine blocks, exhaust manifolds, turbocharger casings, valve bodies, pump housings, gearboxes, electric motors and flanges. We repair cast iron products out of flake iron, spheroidal graphite and Ni-Resist materials. Cast iron and steel are used extensively by various manufacturers of marine diesel engines. Welding of cracked & corroded cast iron engine blocks, cylinder heads, exhaust manifolds & gear box casings enhances and extends the life of rare, select & venerable machines. We undertake weld repair by rebuilding valve seats, manifold lugs and bearing locations.
