Abstract
Recent theoretical work on the design of unusually high-strength steel weld deposits is compared with microstructural studies of an experimental, multipass submerged arc weld deposit. The as-deposited microstructure is found to consist of a mixture of acicular ferrite, bainite and low-carbon martensite. Owing to its low carbon concentration, the structure is highly resistant to tempering, and because the alloy becomes austenitic at a relatively low temperature, the effect of reheating due to the deposition of several layers is found to be minimal. The overall microstructure of the multirun weld thus turns out to be fairly homogeneous, differing little from the as-deposited microstructure.
