On Copper-Steel Joint Arc Welded with Nickel Based Filler

Abstract:

The paper presents some metallurgical and mechanical examinations of the joint between dissimilar metals viz. copper and alloy steel obtained by Shielded Metal Arc Welding (SMAW) using consumable nickel based superalloy electrode as the weld filler. Material microstructures at all the important zones of the weldment are examined with the help of Optical and Scanning Electron Microscopes (SEM). Examinations reveal corrugated weld interfaces with good fusion between the metals and the filler. The weld joints are subjected to tensile and impact tests in ambient conditions. In both the tests, the weldments fracture on copper side with all the weld interfaces remaining intact confirming a strong joint.
