摘要
以高强度低合金Q345钢焊接接头为对象,研究其微观组织和力学性能。结果表明,高强度低合金Q345钢的焊接接头具有优良的弯曲和拉伸性能,且硬度分布均匀。在室温和-40℃的低温下均具有良好的冲击韧度。
The microstructure and mechanical properties of high strength low alloy Q345 steel welded joint were studied. The results show that the high strength low alloy Q345 steel welded joint shows excellent bend and drawing properties, and the distribution of hardness is uniform. The welded joint shows good impact property whatever room temperature and low temperature.
