As complete elimination of porosity from the weld is very difficult, next option available to minimize this porosity, which crucial for safe performance welded components. However, investigation through experiments alone tedious and time consuming. Additionally, limited models are in literature accurate prediction different attributes. The present study, thus, addressees both experimental as we...

The extensive use of the electron beam in manufacturing processes like welding or perforating revealed the high potentials for also using it for solid freeform fabrication. First approaches like feeding wire into a melt pool have successfully shown the technical feasibility. Among other features, the electron beam exhibits high scanning speed, high power output, and beam density. While in laser...

Brake beam is one of the important components working in railway vehicles braking process, which directly affects the security and stability of the high-speed running railway vehicles. Through the research of the cutting and welding technology for the 209T straight plate type brake beam, this paper presents an advanced maintenance method, and designs an automatic cutting and welding machine for...
