The hardfacing deposition with the GTAW process is widely studied addition of metallic powder or solid wire. This study introduces an original method, flux-cored-double-wire (FCDW-GTAW), where wires different compositions are used simultaneously to deposit hardfacing. Because complexity in stabilizing welding system, combined effects parameters should be investigated, allowing elaborate predict...

Cold metal transfer (CMT)-based wire-arc additive manufacturing (WAAM) is a promising method for the production of large-scale and complex metallic parts because its high efficiency, less heat input low cost. However, critical common problem with arc welding processes irregular geometry at beginning end bead due to ignition extinction arc. Based on experimental investigations irregularities dif...

In this article, a case study of load-carrying vehicle chassis with various loading conditions in six maneuvers has been conducted. These include acceleration and deceleration loaded un-loaded situation, drops, pothole, turn, sinusoidal obstacles. Finite element analysis implemented order to calculate stress distribution fatigue life. Stress indicated that the joints stiffness is higher where a...

Background: Although DC Bead has been useful in treatment of multiple and large hepatocellular carcinoma, loading time of doxorubicin into the DC Bead takes a long time of 30-120 minutes. Epirubicin is also used as an antitumor agent together with DC Bead, but its loading efficiency was not sufficiently elucidated. Methods: To shorten loading time of epirubicin into DC Bead (100-300μm, 300-500μ...

A well-designed deposition path is one of the basic prerequisites for successful fabrication a component by based additive manufacturing processes. Three main approaches are currently used to determine path. First, these general templates that applied entire geometry. Nevertheless, this approach suffers from poor adaptability Second, they algorithms where it necessary divide geometry into sub-p...

To study the swimming of the multi-flagellated bacterium Escherichia coli, we deploy a bead-spring hydrodynamic model (Watari and Larson 2010), whose body and flagellar geometry, motor torques, and motor reversals are adjusted to match the experimental observations of the Berg group (Turner et al. 2000; Darnton et al. 2007) during both running and tumbling of the bacterium. In this model, hydro...

The profile of the welding bead changes with process parameters during gas metal arc (GMAW) process, top reinforcement disappears, and penetration becomes sunken when excessive heat input is applied. However, little research work specially planned to cope studying under these circumstances. A systematic study relationships among variables geometric features as well optimization quality presente...
