Abstract
A method of rating the arc maintainability of an electric arc welding stick electrode by creating an arc between the electrode and a workpiece; moving the electrode along the workpiece while maintaining the arc; decreasing either the current or the voltage until a point is reached where the arc is extinguished; determining the open circuit voltage at the point; and, rating the electrode based upon the open circuit voltage point.
Claims34
A method of rating the arc maintainability of an electric arc welding stick electrode for deposing molten metal from said electrode onto a workpiece by using an arc between said electrode and said workpiece, said arc caused by a voltage from a power source where said voltage crates the current of said arc, said method comprising:
- (a) creating said arc between said electrode and said workpiece;
- (b) moving said electrode along said workpiece while maintaining said arc;
- (c) decreasing either said current or said voltage until a point is reached where said arc is extinguished;
- (d) determining the open circuit voltage of said power source at said point;
- and,
- (e) rating said electrode based upon said open circuit voltage point.
