Modelling 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 کاملOn Line Monitoring for Defects in Electric Arc Stud Welding
ABSTRACT The application of on-line monitoring system for recording main welding parameters during electric arc stud welding process at different electric arc stability changes is described in this paper. In the first part of the paper, the basics of electric arc stud welding process, and equipment for stud welding and process monitoring used in experimental part is described. In the second par...
متن کاملBilateral Macular Hemorrhage Due to Welding Arc: A Case Report
Background and Objective: Non-ionized radiation from arc welding may cause retinal lesions such as photo retinitis. In this report, a patient with bilateral macular bleeding which had been caused by inappropriate use of protective safety glasses is introduced. Case Report: On 26 July 2008 a 23-year-old male with blurred vision was referred to Shahid Beheshti's faculty of Rehabilitation Clinic....
متن کاملDevelopment of an automatic arc welding system using an adaptive sliding mode control
This paper develops an automatic welding control scheme for alternating current shielded metal arc welding (SMAW) system. A mathematical model of the welding control system is derived and the system parameters identified. An adaptive sliding mode controller is designed to estimate the bound of the system uncertainties and to modulate the electrode feed rate in such a way that the desired arc le...
متن کاملCytotoxicity of electric spot welding: an in vitro study
Objective: The welding process involves metal ions capable of causing cell lysis. In view of this fact, the aim of this study was to test the hypothesis that cytotoxicity is present in different types of alloys (CrNi, TMA, NiTi) commonly used in orthodontic practice when these alloys are subjected to electric spot welding. Methods: Three types of alloys were evaluated in this study. Thirty-six ...
