    摘要： A method of welding articles formed of single-crystal superalloys, particularly single-crystal nickel-base superalloys containing 10 weight percent or more of refractory metals, and welded assemblies formed thereby. A shim is positioned between the articles, and a backing strip is preferably positioned to contact both articles and bridge the gap between the articles. The articles are then welded together using a high energy beam with a low current pulse frequency and low travel speed.
