In SMAW (shielded metal arc welding) process, selecting appropriate values for process variables is essential in order to control weldment characteristics. Also, conditions must be selected that will ensure a predictable and reproducible weld bead. In this investigation the effects of cryo-treatment and preheating on various metallurgical aspect, namely, the depth of HAZ, weld interface, grain.
Some research effort has been devoted (8) to the modeling of damage and residual stresses induced by welding. In (9) the residual stresses are studied during one-pass arc welding in a steel plate. According to this research, the residual stresses clearly decrease in a short distance from the weld bead in case of welds lengths lower than 50 mm and thicknesses in the range of 5 to 8 mm. Other.
Research on welding of materials like steel is still critical and ongoing. An attempt has been made to analyze the effect of process parameters in qualitative manner for welding of AISI1040 steel using processes of Shielded Metal Gas Welding (MIG and TIG). Taguchi method is used to formulate the experimental layout. Exhaustive survey suggest that 5-7 control factors viz., arc voltage, arc.
Welding Research Paper 1394 Words 6 Pages GMAW (Gas Metal Arc Welding) is more economic; Springer reports that “ GMAW is an economic process because it has higher speeds and higher deposition rates than manual arc welding.
In Section A, research papers related to MIG welding and in Section B, various research papers related to SMAW welding have been reviewed thoroughly. SECTION A Xinhua Tang et al. studied the effect of preheating in NG-GMA welding. The approach used is statistical analysis of different specimens at predefined parameters. 5083 Al alloy is used as the base material while filler material is ER5183.
