Study on high-quality and high-speed welding using tandem electron beams

Study for high-quality and high-speed welding using tandem electron beams: Experimental data of the part welded by electron beams, which weld using only parent metals, are indispensable to compare effects of complex welding and other welding techniques of steel materials. Study thus welds matched cast iron corresponding to SCM435 using electron beams and subjects to confirmation of welding performance, transitional characteristics of the welded part, and mechanical characteristics, as well as to observation of morphology, to explore applicability of electron beams.
