摘要： A welding system and method is disclosed for girth welding high strength materials using a short arc welding process and a self-shielding electrode. The welding system contains a welding apparatus which advances the self-shielding electrode towards a workpiece to be welded and controls the arc length and the operation of the apparatus so that the weld satisfies the requirements for welding at least American Petroleum Institute Grade X-80 line pipe. The system additionally contains a power source with a controller for creating a current pulse introducing energy into the electrode to melt the end of the self-shielding electrode and a low current quiescent metal transfer section following the end of the melting pulse during which the melted electrode short circuits against the workpiece.

摘要： Disclosed are techniques and compositions for arc welding consumables such as electrodes that reduce the energy otherwise required for the welding. Particularly, the techniques and electrode compositions can reduce the extent of contamination of weld metal in an arc welding operation. The techniques and compositions promote exothermic reactions during the welding process which reduce the energy otherwise required of the arc. Lower energy arcs can be of shorter length, which thereby reduce the potential for weld contamination by agents from the atmosphere or shielding gas. The techniques and compositions can also be used to selectively tailor shape of the resulting weld, achieve particular weld deposition rates, achieve particular cooling rates and thus influence weld properties, and also enable formation of certain phases in the weld metal.

摘要： A welding system is disclosed for performing a short arc welding process between an advancing wire electrode and a workpiece. The system comprises a power source with a controller for creating a current pulse introducing energy into the electrode to melt the end of the electrode and a low current quiescent metal transfer section following the end of the melting pulse during which the melted electrode short circuits against the workpiece; a timer to measure the actual time between the end of the pulse and the short circuit; a device for setting a desired time from the pulse to the short circuit; a circuit to create a corrective signal based upon the difference between the actual time and the desired time; and, a circuit responsive to the corrective signal to control a given parameter of the current pulse. Also disclosed is a strategy for arc welding utilizing a cored electrode that produces welds with low levels of contaminants and which are strong, tough, and durable. The arc welding process generally utilizes an AC waveform. The cored electrode can be a self-shielded flux cored electrode (FCAW-S). Various electrode compositions are described that are particularly beneficial when used in conjunction with an AC waveform.
