摘要

A number of each of the four lots of subject electrodes were deposited under identical conditions, except for the slight variation of the current rate which was regulated to the best advantage of each lot. A welded joint was produced depositing electrodes from each lot into a separate assembly of 3/8 thick rolled, annealed monel metal plates. The assemblies were not preheated. Subsequently, a portion of each welded assembly was dissected into test specimens without giving this portion of the assemblies any post heat treatment. The remaining portion of the assemblies were heat treated and afterwards were dissected into test specimens also. The weld metal was examined metallographically. The electric cores of the four lots, as well as the weld metal produced by them, were chemically analyzed for their aluminum content. Physical tests were performed with the specimens produced for this purpose and in addition the hardness of the weld metal at the different regions of the weld was determined.
