The Performance Of The Heat Affected Zone Of 9% Ni Steel Narrow Gap Joint Performed By The Gmaw Process With Rotating Electrode, Jorge Carlos Ferreira Jorge, Jeferson Frederico Monteiro Costa, Matheus Campolina Mendes, Luís Felipe Guimarães De Souza, Hiron Akira Yamada Magalhães, Leonardo Sales Araújo

Journal of Metals, Materials and Minerals

This work investigates the mechanical properties and microstructural evolution of the heat-affected zone of 9% Ni steel narrow-gap welded joints produced by the GMAW process with a rotating electrode, since no literature on this subject is available. This process is an innovation of the GMAW process, which permits narrow gap welding because the circular motion of the electrode overcomes the main issue of the sidewall's lack of fusion observed in the conventional process. However, the rotation movement of the electric arc imposes a higher peak temperature at the heat affected zone, which can negatively affect the mechanical properties. The joints …
