Flux cored welding electrodes comprise a iron based metal sheath and either a flux or metal core within the sheath, enclosing core ingredients. The core ingredients and sheath together comprise, in weight percentages based on the total weight of the electrode, very low levels of manganese. While having low levels of manganese the electrodes satisfy the strength and safety requirements required of commercial electrodes. Embodiments contain manganese in the range of 0.09 to 0.19% by weight of the electrode, along with other components.

Low manganese welding electodes

A method and system to weld or join workpieces employing a high intensity energy source to create a weld puddle and at least one resistive filler wire which is heated to at or near its melting temperature and deposited into the weld puddle.

Method and system to start and use combination filler wire feed and high intensity energy source for welding

A system and 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 at least the open circuit voltage point.

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.

A welding electrode comprising a metal core and a coating material that includes flux compounds is at least partially coated on an outer surface of said metal core. The tip of the welding electrode is beveled and a portion of the beveled tip has an end coating material which includes an electrically-conductive material.
