When welding low alloy 1 1/4 Cr 1/2 Mo and 2 1/4 Cr 1 Mo with up to 0.05% max carbon, typically 8018-B2L / 9018-B3L (L = low carbon) can be used. When welding higher strength alloys or when tempering and quenching are required to attain the higher strengths the higher carbon 8018 B2 and 9018 B3 electrodes are utilized.

Stick Electrodes For mild and low alloy steel welding. Various coating types are available for a wide range of applications. Various coating types are available for a wide range of applications. MIG Wires and TIG Rods Filler metals made from the highest quality steel How to Weld Cast Iron Metal Casting BlogNov 22, 2017 · Identify the alloy; Clean the casting thoroughly; Select a pre-heat temperature; Select an appropriate welding technique; Before any welding project, be sure to clean the casting, pre-heat the alloy, and choose an appropriate welding technique. Identify the alloy. Cast irons are a family of iron-carbon alloys. Their high carbon content (usually 24%) gives cast iron its characteristic hardness.
Benefits of Investment Casting:Precision investment castings create the finest surface finishes in ferrous and non-ferrous parts. Clean, intricate designs with tight tolerances speed manufacturing time without machining or sanding. Complex metal castings poured from more than 100 metals and alloys require no welding, assembling or finishing work. . Precision casting drives multiple parts to Iron, Steel, and Nickel-Alloy Centrifugal Castings Centrifugal steel castings, iron castings, and nickel alloy castings are used extensively in the automotive, power generation, petrochemical, oil & gas, mining, and drilling markets. As centrifugal casting is a form of die casting, the tooling expense associated with sand casting or investment casting is largely eliminted.

Cast steel and cast iron parts in gas turbines can usually be repaired by welding, provided the limited strength of the weld heat-affected zone is taken into account.Many cases of severe impact damages and corrosion damages thus can be repaired using this process. Ferritic/martensitic stainless steels are widely used for compressor blades and steam turbine blades. welding products, casting parts, forging parts - ECPlazaShanghai Zhongzhou Special Alloy Material Co., Ltd. was established in 1993 which mainly for manufacturing and selling cobalt base and nickel base special alloy, we have more than 15 years manufacturing experience in cobalt and nickel series of bare rods, electrodes, precision (including sand ) casting and forging parts.
welding of AM60B cast alloy revealed a signific ant increase in fusion-zone porosity for most of welding conditions (Zhao and DebRoy, 2001). The pre-existing pores, their coalescence and expansion were seen as the cause of porosity increase. The keyhole was found more stable than during welding of Al alloys but its stability did not substantially affect the overall porosity.
