Using flux-cored wires in multi-arc welding
Welding International, 2016AbstractThe mathematical model of non-linear thermal processes in multi-arc welding of electric welded pipes is described. The model can be used for evaluating the changes in the structure of the welded joint produced using flux-cored wires. The microalloying elements are analysed and the results are used for studying the effect on the mechanical ...

Structural characteristics of multipass flux cored arc steel welds
Science and Technology of Welding and Joining, 2003Abstract The effect of heat input, shielding gas, and welding technique on the structure of the weld metal has been investigated in all weld multipass test plates produced by flux cored arc welding using 1.2 mm diameter boron microalloyed rutile, metal cored, and rutile flux cored wires.

Diffusible Hydrogen Control in Flux Cored Arc Welding Process
Key Engineering Materials, 2013One of the types of hydrogen degradation of steel welded joints is cold cracking. The direct cause of the formation of cold cracks is simultaneous presence of hydrogen, residual stresses and brittle structure. The way of preventing the occurring of degradation is to eliminate at least one of these factors.

A study on quality of weld in flux cored arc welding process
International Journal of Precision Technology, 2014Flux cored arc welding (FCAW) is a semi–automatic or fully automatic welding method that is widely used for welding large and thick sections, especially in the flat position. The welding can be performed with shielding gas (FCAW–G) or without shielding gas (FCAW–S).

Tandem Flux-Cored Arc Welding for High Strength Line Pipe
Volume 3: Materials and Joining; Risk and Reliability, 2014The benefits of mechanized welding for pipeline construction are well known, as reflected by the high industrial acceptance and usage of its variations. However, the engineering and qualification costs associated with the preparation of alternative acceptance criteria for typical pulsed and short-circuit MIG (GMAW-P and GMAW-S) girth welds can make the

Abstract In the flux-cored arc welding (FCAW) process, the heat for welding is produced by an electric arc between a continuous filler metal electrode and a workpiece. This article discusses the advantages and disadvantages and applications of the FCAW process. It schematically illustrates the semiautomatic FCAW equipment used in the gas-

Arc welding of grooved rails – manual metal arc welding versus flux cored arc welding
2012Experience collected by the members of the Chair for Railways during 15 years of the supervision of re/construction of tram tracks in the Croatian capital Zagreb and city of Osijek revealed that the largest percentage of local rail damage occurs at the welded rail joints.

NUMERICAL ANALYSIS OF THE WELD BEAD PROFILESIN UNDERWATER WET FLUX-CORED ARC WELDING
Acta Metallurgica Sinica, 2013Underwater wet flux-cored arc welding(FCAW) has great potential prospects of wide application in ocean engineering due to its easiness of automation and high weld quality.However,the thermal process of underwater wet welding is more complicated:the arc energy distribution is more concentrated in high-pressure environment of underwater,the convection ...

Effects of welding parameters on tensile strength of weld metal in flux cored arc welding
Science and Technology of Welding and Joining, 2008Effects of welding parameters such as welding current, voltage and travel speed on the tensile strength of weld metal in flux cored arc welding were studied. The results were interpreted in terms of chemical composition and microstructural change in the weld metal. When heat input was increased to 2˙1 kJ mm–1 by increasing welding current, the tensile
