The weldability of 800 MPa high strength steel has been studied with 20 mm and 42 mm thickness plates by the maximum hardness test of heat-affected zone, Y slit cracking test and the test of weld energy input etc.
采用热影响区最高硬度试验、斜Y型坡口裂纹试验及焊接线能量的测试等手段研究了板厚分别为20mm及42mm的800MPa高强钢的焊接性。
The cross-section hardness distribution curve of coating and corrosion resistant test show that with increasing distance between coating and interface, the coating hardness increases firstly and reaches the maximum value of 580 HV at the distance of 10 μ m from interface, and then decreases.
膜层截面硬度分布曲线和耐蚀性实验表明,膜层硬度随着膜层与界面距离的增加起初增大,在距离界面10μm处达到最大值为580HV,之后逐渐降低;
