摘要

采用钨极氩弧焊（TIG）+焊条电弧焊（SMAW）对10 mm厚的N06022镍基合金进行焊接，分析研究接头的微观组织、显微硬度、腐蚀性能和拉伸性能。研究表明：采用TIG+SMAW焊接接头表面成形良好，整个焊缝呈银白色，半椭圆状的鱼鳞纹均匀分布；母材与焊缝区组织存在明显的分界线，且无明显的热影响区域，焊缝区域组织为等轴晶和树枝晶组织；整个焊接接头的硬度呈“M”形分布，NZ区域的显微硬度较为稳定，在250 HV附近，HAZ区较BM区域高，而较NZ区域低，从HAZ区域到NZ区域接头的显微硬度变化不大；焊接接头的平均抗拉强度（799 MPa）高于母材（782 MPa），焊接接头较母材提高了2.56%，保证了该类焊接结构的可靠运行，接头的断裂形式为韧性断裂；接头腐蚀性能满足设备技术要求和标准规定。

Abstract

10 mm thick N06022 nickel base alloy was welded by TIG + SMAW. The microstructure

microhardness

corrosion properties and tensile properties of the joint were analyzed and studied. The results show that the surface of the joint welded with TIG+SMAW is well formed

the whole weld is silver white

and the semi-elliptical fish scale is evenly distributed. There is an obvious dividing line between the base material and the weld zone structure

and there is no obvious heat-affected zone. The weld zone structure is equiaxed and dendrite. The hardness of the whole welded joint is distributed in an "M" shape

and the microhardness in the NZ region is more stable. Near 250 HV

the HAZ region is higher than the BM region

while the NZ region is lower. The microhardness of the joint from the HAZ region to the NZ region has little change. The average tensile strength of welded joint (799 MPa) is higher than that of base material (782 MPa)

and the average tensile strength of welded joint is 2.56% higher than that of base material

which ensures the reliable operation of this kind of welded structure. The corrosion performance of the joint meets the technical requirements and standards of the equipment.
