ABSTRACT:
A flux cored arc welding process for depositing a weld metal onto a revolving cylindrical workpiece. A weld deposit zone is moved along a longitudinal axis of the revolving cylindrical workpiece at a relative feed velocity of 1/32 to 2 inches per each revolution of the cylindrical workpiece, per each 0.1 foot to 2 feet per minute circumferential rate of revolution of the cylindrical workpiece. The weld deposit zone deposits a weld metal onto the revolving cylindrical workpiece in a spiral or helical fashion or manner.
