Numerical analysis of molten pool behavior during underwater wet FCAW process

Journal of Manufacturing Processes, 2018
Abstract Underwater wet flux-cored arc welding is a candidate method for onsite fabrication and maintenance of underwater structures. For a systematic understanding of physical mechanisms of this welding process, transient three-dimensional CFD models encompassing the effects of slag and underwater environment on heat and mass transfer within the ...

Developing rules bases on the influence of welding parameters in FCAW process from ANN model

International Journal of Mechatronics and Manufacturing Systems, 2010
The influence of welding parameters in Flux-Cored Arc Welding (FCAW) process on the bead geometry and Heat Affected Zone (HAZ) were determined using Artificial Neural Network (ANN). The significance of all the variables on the properties of the weld zone have been assessed by ANN and found to be in accordance to the existing knowledge. The roles of the

Hyperbaric welding by the FCAW process

Welding International, 1993
Summary The present work is part of a research project aiming at full implementation of robots for underwater welding at great depths (beyond 600 m). This study discusses preliminary results from basic investigations on the weld metal microstructures and toughness of the flux‐cored C‐Mn‐1% Ni wire used for welding under hyperbaric conditions. Under the

Influence of FCAW process parameters in super duplex stainless steel claddings

Materials Today: Proceedings, 2020
Abstract Flux cored arc welding (FCAW) is preferred in cladding process due to its augmented efficiency and higher deposition rate. In this research work, to investigate the interaction effect between process parameters of flux cored arc welding on hardness and bead geometry of cladded plate on super duplex stainless steel.

FCAW process optimization using the multivariate mean square error

Welding International, 2012
Optimization of welding processes is not a trivial task, mainly due to the great number of required and desirable characteristics that must be analysed. Moreover, the optimization of a welding process with multiple characteristics without considering the variance–covariance structure may lead to inadequate optimum.

Effective dose in SMAW and FCAW welding processes using rutile consumables

Journal of Radiological Protection, 2013
The shielded metal arc welding (SMAW) and flux cored arc welding (FCAW) processes use covered electrodes and flux cored wire as consumables. Among these consumables, ones containing rutile are the most widely used, and since they have a considerable natural radioactive content, they can be considered as NORM (naturally occurring radioactive material ...
