摘要

ERNiCrMo-3焊丝因其在高温力学性能和耐腐蚀性能上的优势，广泛应用于航空航天、能源化工等领域。在实际生产过程中，焊丝的送丝稳定性已经成为影响焊接质量和生产效率的重要因素。本文选取常用的5种不同厂商生产的ERNiCrMo-3镍合金焊丝，通过送丝稳定性测试，量化了焊丝的送丝速度、送丝阻力，分析了影响送丝稳定性的因素。测试结果显示，送丝阻力和速度在不同品牌焊丝间存在较大差异，其中3#焊丝表现出最不稳定的送丝阻力和送丝速度。通过对比焊丝表面粗糙度，发现焊丝表面缺陷与送丝稳定性存在显著相关性。综合分析表明，焊丝的表面质量会对送丝稳定性产生影响。

Abstract

ERNiCrMo-3 welding wire is widely used in aerospace

energy

chemical engineering

and other fields due to its advantages in high-temperature mechanical properties and corrosion resistance. In actual production

the wire feeding stability has become an important factor influencing welding quality and production efficiency. This paper selects five commonly used ERNiCrMo-3 nickel alloy welding wires produced by different manufacturers. Through wire feeding stability tests

the feeding speed and feeding resistance of the wires are quantified

and the factors affecting feeding stability are analyzed. The test results show significant differences in feeding resistance and speed among different brands of welding wires

with Wire No. 3 exhibiting the most unstable feeding resistance and speed. By comparing the surface roughness of the welding wire

it is found that surface defects of the wire are significantly correlated with feeding stability. The comprehensive analysis indicates that the surface quality of the welding wire can affect the wire feeding stability.
