The Physics of Arc Welding Processes
نویسنده
چکیده
welding is an extremely complex process; however, due to its commercial importance, it is essential that a more thorough study of the various processes be undertaken. Three examples of areas requiring greater understanding of arc physics are presented. The first discusses heating or cooling of the metal at the cathode; the second describes variations in heat transfer using various shielding gases and the last describes droplet formation in gas metal arc welding.

Elimination Back Gouging Operation in Submerged Arc Welding Butt without Chamfers ASTM A516 (TECHNICAL NOTE)
Submerged arc welding is used widely in oil and gas industry construction for storage tanks, pressure vessels, shipbuilding and etc. One of the processes of submerged arc welding is back gouging operations. This paper presents a way to remove the back gouging operation from the submerged arc welding process. For this purpose, effects of submerged arc welding parameters onA516-70steel sample wer...
متن کاملModelling of Electrode-arc Coupling in Electric Arc Welding
Modelling of the arc in electric arc welding is significant to achieve a better process understanding, thus gain better weld quality and a more efficient production process. It requires knowing the conditions at the surfaces of the anode and cathode. These conditions are very difficult to set from measurements and should be calculated. This requires modelling the complex physics of the electrod...
متن کاملOccupational exposure to welding gases during three welding processes and risk assessment by SQRCA method
Background: Hazardous chemical agents in the welding operation are a mixture of metal fumes and toxic gases, the inhalation of which causes adverse health effects among welders. The emission of gases in the workplace is a logical cause for concern regarding the potential development of respiratory disease. The aim of the present study was to determine the concentration values of gases discharge...
متن کاملInvestigating the Effect of Joint Geometry of the Gas Tungsten Arc Welding Process on the Residual Stress and Distortion using the Finite Element Method
Although a few models have been proposed for 3D simulation of different welding processes, 2D models are still more effective in design goals, thus more popular due to the short-time analysis. In this research, replacing "time" by the "third dimension of place", the gas tungsten arc welding process was simulated by the finite element method in two dimensions and in a short time with acceptable ...
متن کاملAn Evaluation of Welding Processes to Reduce Hexavalent Chromium Exposures and Reduce Costs by Using Better Welding Techniques
A group of stainless steel arc welding processes was compared for emission rates of fume and hexavalent chromium, and costs per meter length of weld. The objective was to identify those with minimal emissions and also compare relative labor and consumables costs. The selection included flux-cored arc welding (FCAW), shielded-metal arc welding (SMAW), and multiple gas metal arc welding (GMAW) pr...
