Abstract
This paper investigates the reliability of using the Flux Cored Arc Welding (FCAW) process Temper Bead welding (TBW) technique. In this paper, an automatic welding machine was used to manufacture the welding. An experimental investigation was conducted to find the optimal welding parameters of the TBW technique using FCAW process. This experimental investigation was done in order to provide the desired mechanical properties and microstructures without Post-Welding Heat Treatment (PWHT). The welding process is associated with residual stresses in the parent material. In this paper, the weld penetration depth into the base material is used as a guide to the amount the residual stresses. In this study, analytical solution was used to support the use of the FCAW process to the TBW technique to repair damaged structures. This solution was based on statistical and experimental data. These data were used to establish the relationships between the technological parameters of FCAW process and the factors responsible for the quality of the required structure. In this paper some the advantages of using the FCAW process over the other commonly used TBW techniques such as manual metal arc welding (MMAW) and gas metal arc welding (GMAW) which use solid wire are shown.
