Summary:

A study was made on the metallographic, microchemical and microhardness properties of parallel gap welds and their relationship to each other.The parallel gap welding process is often used to join metals with large differences in their physical properties over wide ranges of energy inputs. The resultant weld microstructures vary over a full spectrum from the so-called brazed joint to a completely fused weld area. It was the purpose of this study to determine the chemical and mechanical variations on a microscale in the weld area to aid in an intelligent interpretation of the microstructure.The bulk of the work was done on gold plated Kovar leads (0.015 0.004) welded to nickel ribbon. The main conclusions may be summarized as follows:
