摘要
针对黄铜换热器管头焊接工艺进行研究,采用宏观检验、金相组织观察、硬度测试等方法来表征焊接接头的质量。探讨黄铜换热管头的焊接工艺,并通过对焊缝、母材、管材及热影响区组织的金相分析,找出比较合理的黄铜换热器管头焊接工艺方案。
The welding process of brass heat exchanger tube and shell was studied;the welding quality was tested by macroscopic examination, microstructure observation and hardness test. Through metallographic analysis of welding seam, base metal, pipe material and organization at heat-affected zone, reasonable welding process scheme of the brass heat exchanger tube and shell was determined.
