Welding-HY-Steels for special naval requirements

Welding-HY-Steels refers to processing a family of steels that owe their name to High Yield Strength..This was the main property designed into the materials as they were developed in the form of thick plates..That occurred in the sixties of the past century,at the request of the US Navy,mainly for fabrication of ship hulls and submarines..Within this class,that includes HY-80,HY-100,HY Wear of Polycrystalline Boron Nitride Tool During the The wear issue of a polycrystalline boron nitride (PCBN) tools during the friction stir welding of two grades of steel,DH36 and EH46,was studied.Two welding traverse and tool rotational speeds were used when welding the DH36 steel.A low tool speed (200RPM,100 mm/min) and a high tool speed (550RPM,400 mm/min) were denoted by W 1D and W 2D,The Welding Handbook - Wilh.Wilhelmsen3.03 Wires for Wire Welding 217 3.04 Gas Welding Rods Fluxes 241 3.05 Brazing Rods Fluces 249 3.06 Cold Repair Compounds 275 4.01 Electrode welding gouging 331 4.02 TIG Welding 381 4.03 Wire Welding 403 4.04 Plasma Cutting 441 4.05 Current Distribution System 459 5.01 AC/OX cutting,welding,brazing 465

Grade D and E series (inlcuding AH32/36,DH32,DH36,EH32,EH36) shipbuilding steel plates require good low temperature toughness and good welding performance.The production high-strength shipbuilding steel plate needs to be normalized by means of controlled rolling and controlled cooling or heat treatment processes with more complete equipment.Preheating,Interpass and Post-Weld Heat Treatment SMAW is commonly called stick or covered electrode welding.It is a manual process,where an arc is struck between a flux-covered consumable electrode (filler wire) and the workpiece.Decomposition of the flux coating generates the shielding gas and provides fluxing elements to protect the molten weld metal.Preheating,Interpass and Post-Weld Heat Treatment SMAW is commonly called stick or covered electrode welding.It is a manual process,where an arc is struck between a flux-covered consumable electrode (filler wire) and the workpiece.Decomposition of the flux coating generates the shielding gas and provides fluxing elements to protect the molten weld metal.
