42Cr2Mo steel is an ultra-high strength steel. The steel has high strength and toughness, good hardenability, no obvious temper brittleness, and small deformation during quenching. After quenching and tempering, 42Cr2Mo alloy has a higher fatigue limit and resistance to multiple impacts. Good impact toughness at low temperature, high creep strength and enduring strength at high temperature. The steel A283 Gr A CS steel carbon plate usually adopts surface quenching after quenching and tempering as the heat treatment plan.
The yield strength of Q690D steel plate is 690 Mpa and the impact temperature is - 20℃. A283 Gr A CS steel carbon plate, Q690D steel plate has high strength, good plasticity and toughness, good weldability and good cold and hot performance. Q690D steel plate is mainly used to manufacture various large engineering structural components and construction machinery. Because of its high strength and good toughness, Q690D steel plate can reduce the self weight of components and meet the requirements of large-scale and lightweight engineering components and equipment under the condition of ensuring strength, stiffness and reliability.
First to determine the welding methods, such as hand arc welding, submerged arc welding and tungsten argon arc welding, melting polar gas shielded welding machine, and so on are very many different kinds of A283 Gr A CS steel carbon plate welding method, can only be chosen according to specific situation, determine the welding method, and make welding process parameters, different kinds of welding process parameters, such as manual welding mainly includes: electrode model (or brand) diameter, current, voltage, welding power source type and polarity connection, welding layer number, number, inspection method, etc.
