Hybrid laser arc welding of thick-walled ferromagnetic steels with electromagnetic weld pool support
(2017)
Electromagnetic weld pool support system is illustrated successfully for hybrid laser arc welding of 20 mm ferromagnetic steels. Welding of thick-walled steels in flat position and reduced welding velocities is possible. Skin depth must be smaller than the plate thickness for protect the electric arc against external oscillating magnetic field. Residual magnetic field has a low influence, the deflection of the arc can be neglected. At high AC frequency more AC power is needed for ideal compensation (Hysteresis losses).
