Design Of An Automatically Controlled-Feed, Constant Current Arc Generating Machine For Consumable Electrodes, Dhansukh J. Chauhan

Theses and Dissertations

Good welding research requires accurate control of the variables involved,to achieve consistent results. The variables involved in arc welding are of the dependent and independent type. Control of the independent variables such as arc current, arc voltage and welding velocity is necessary to control the independent variables such as penetration, electrode consumption rate, etc. The purpose of this thesis was to design, develop and test an automatic welding machine which controlled the above variables within the limits required for welding research.
