【摘要】 通过间接估算和试验两种途径对连铸10CrNiCu钢板的焊接预热温度进行了研究,研究结果表明连铸10CrNiCu钢具有较好的焊接抗裂性,一般情况下焊接不需要预热,但是在低温高湿度、碳当量较高和结构拘束度大的情况下焊接时需要预热到60℃以上。更多还原

【Abstract】 The preheating temperature for the welding of concast 10CrNiCu steel is analyzed by estimation and experiment.The results show that the steel has good weldability and preheating is unnecessary in ordinary welding environment, but on the conditions of low temperature with high humidity,high carbon equivalent and intense structure restraint ,the preheating at above 60℃ is demanded.更多还原
