Submerged Arc Welding: A Review
In industries and research organizations most widely used welding methods are shield metal arc welding (SMAW), gas metal arc welding (GMAW), gas tungsten arc welding (GTAW) and submerged arc welding (SAW). The SAW process is often preferred because it offers high production rate, high melting efficiency, ease of automation and low operator skill requirement. This review will be very helpful for...
متن کاملThermaltransport Phenomenon of Submerged Arc Welding Process
Original scientific paper In present work, thermal transport considering heat radiation by oval heat source shape and heat transfer of molten moving electrode was presented. In present paper, an analytical solution was presented by aggregating temperature increments caused by applying liquid metal and heat radiation of moving electrode. The assumptions for the study were heat source of temperat...
متن کاملModelling and optimization of advanced submerged arc welding process for stainless steel cladding
Industries involved in surfacing operations use various fusion welding especially arc welding processes. These operations demand high deposition rates but at low penetration values in the base metal. Conventional SAW, besides its high deposition characteristics, employs high values of welding current and is not many times favoured for surfacing due to high degree of dilution of surfacing alloys...
متن کاملWeld Quality Prediction of Mild Steel Pipe Joint during Shielded Metal Arc Welding through fuzzy Logic
The present paper describes fuzzy logic simulation of shielded metal arc welding (SMAW) process to predict the Quality of weld joint. It describe the quality of weld joint & effect of welding current, voltage and welding speed on tensile strength of shielded metal arc pipe welded mild steel joints. An ERW Mild steel pipe I S 1239 of 6 mm thickness and 150 mm diameter were used as the base mater...
متن کاملModeling of Transport Phenomena in Gas Tungsten Arc Welding of Ni to 304 Stainless Steel
This study investigates transport phenomena in the weld pool (WP) of gas tungsten arc (GTA) welding of Nickel to 304 stainless steel. A finite element 3D simulation of fluid flow and heat transfer of spot welding without consumable is accomplished which leads to prediction of the weld zone shape, weld penetration and dilution of alloying elements. The model includes magneto-hydrodynamics (MHD),...
