摘要
采用间接法和直接法对NK HITEN 610U2L钢的焊接冷裂纹敏感性进行了研究,结果表明,该钢具有较低的焊接冷裂纹敏感性。对于50 mm厚NK HITEN 610U2L钢板的对接焊,推荐其焊前预热温度不低于100℃。
The susceptivity to welding cold crack of NK HITEN 610U2L steel has been studied by indirect and direct methods The results indicate that the NK HITEN 610U2L steel has low sensitivity to welding cold cracking and a preheat temperature of no less than 100℃ for the butt welding of 50mm plate steel is recommended
