INTEGRATED SHIELDING GAS AND MAGNETIC FIELD DEVICE AND WELDING SYSTEM FOR DEEP GROOVE WELDING

摘要

A welding system (100) is provided which can weld in narrow gap thick walled work pieces, the welding system (100) having a magnetic field unit which contains a magnetic coil (117), a magnetic field probe (107), and a shielding gas tube (105) and nozzle (106). The unit having a shape and configuration which delivers the shielding gas and magnetic field close to the welding arc so as to provide for a shielded welding arc which is manipulated as desired by the magnetic field.
