摘要/Abstract

摘要： 根据刚性拘束裂纹试验机理，自主研制了国内首台大吨位高强钢刚性拘束焊接冷裂纹倾向试验装置，其具有精准的测量系统，完全适应48 h的拘束应力维持时间，该机可提供最大1 200 kN的试验力。利用该冷裂试验装置进行E36钢板对接接头刚性拘束裂纹试验，对比分析GFL-71NI焊丝（国产）和DW-A55L焊丝（进口）的冷裂纹敏感性。结果表明，通过药芯焊丝气体保护焊接方法施焊，采用GFL-71NI焊丝获得接头的临界拘束距离大于DW-A55L焊丝接头，经计算GFL-71NI焊丝接头的临界拘束度和临界拘束应力均小于DW-A55L焊丝接头，最终得到GFL-71NI焊丝接头的冷裂敏感系数高于DW-A55L焊丝接头，数值分别为0.345 147和0.326 094，表明DW-A55L焊丝的抗冷裂性能优于GFL-71NI焊丝。金相分析显示，与GFL-71NI焊丝接头相比，DW-A55L焊丝接头焊缝组织更均匀，晶界铁素体含量明显减少；过热区组织中的淬硬组织含量也较少，这显著降低了DW-A55L焊丝接头的冷裂倾向。

Abstract: Domestic first large-tonnage rigid restraint welding cold cracking tendency test device is self-developed according to the rigid restraint crack test mechanism, which has a precise measuring system and could fully meet the constraint stress holding time of 48h, and the maximum test force of this device is 1200 kN. The rigid restraint crack test of E36 steel plate with butt joint is carried out by using this cold cracking test device and the cold cracking susceptibility of GFL-71NI welding wire (domestic) and DW-A55L welding wire (inlet) are compared and analyzed. Results shows that the critical restraint distance of joint obtained by using GFL-71NI wire is larger than that of DW-A55L wire joint when flux-cored wire gas protection welding method is used, and the critical restraint degree and critical restraint stress of GFL-71NI wire joint are less than that of DW-A55L wire joint by calculating, the cold cracking sensitivity coefficient of GFL-71NI wire joint is higher than that of DW-A55L wire joint and the values are 0.345 147 and 0.326 094 respectively, which indicates that the anti-cracking performance of DW-A55L wire joint is better than that of GFL-71NI wire joint. Metallographic analysis shows that the weld microstructure of DW-A55L wire joint is more uniform and the content of grain boundary ferrite reduces significantly compared with GFL-71NI wire joint; and the content of hardening microstructure in overheated zone of DW-A55L wire joint is less too which significantly reduces the cold cracking tendency of DW-A55L wire joint.
