Microstructure and mechanical properties of multi-pass TIG 6 3counting atoms by the gram Strip surfacing welding
Sep 11, 2019 · A welding pad was used to provide an Argon protection environment on the back of the weld during the bottom welding process to avoid contact with the air. The Schematic of the bevel used in TIG welding process was shown in figure 1, and the welding pass was 21 passes. The welding process parameters were shown in table 3.Some results are removed in response to a notice of local law requirement.

Both the disappearance of -Cu and existence of CuAl and Al on the peeling surface (Cu surface) prove that further cold rolling process can promote the combination of Cu and Al atoms and the formation of metallic bonds.Materials | Free Full-Text | A New Approach in Surface 6 3counting atoms by the gram Strip surfacing weldingIn the current study, a new approach for surface modification and surface hardening of aluminum alloys is developed. The method is based on the logic of in-situ reinforcing FSP strategies. The novelty of the proposed process is the application of a bulk reinforcing metallic material instead of metallic powders. The FSP was carried out on aluminum alloy AA5083—thick plates.
