Zusammenfassung:	Arc welding systems, apparatus and methods are for hardfacing are provided, including particle feeding apparatus. In one aspect the workpiece is moved in an oscillatory fashion while keeping the welding torch and the particulate delivery system stationary during at least a portion of welding pass. The welding torch and particulate delivery system may also be moved in a non-oscillatory fashion. Process speeds of about 18-30 in/min can be obtained with carbide incorporation of greater than 30% and uniform distribution.
