摘要
研究了重型吊车梁用D36低合金高强钢的焊接性。通过试验表明:采用YT506A低氢焊条施焊,可以获得良好的焊接接头性能;D36钢具有较大的氢致开裂敏感性,但抗层状撕裂的能力较高。
The paper investigates the weldability of D36 HSLA steel used for heavy crane beams. The experimental results indicate that the better joint properties can be obtained by using YT 506A low hydrogen electrode to do the weld. D36 steel possesses rather high sensitivity to hydrogen cracking and is well enough to resist laminal tearing.
