The invention relates to an arc paraxial
welding device of a
laser consumable
electrode additionally provided with a high-frequency
magnetic field. The arc paraxial
welding device comprises a
welding machine, a welding gun, a welding wire, a
laser coil, an exciting coil, an exciting power source, a combined welding head-welding gun clamping mechanism, a connection piece, a
laser head and a combined welding head type connection piece. Compared with the prior art, the arc paraxial welding device provided by the invention has the beneficial effects that: the arc paraxial welding device has the characteristics of small size, low cost and strong practical applicability; the exiting coil acts on photo-induced
plasma generated by laser, so that the
screening effect of the photo-induced
plasma on laser can be reduced, the use rate of
electromagnetism and the own stable burning capacity of arc can be improved, molten drops are prompted to smoothly transit and
metal in a furnace
hearth is prompted to sufficiently flow, and the defects of generation of splashing and vents in welding beams and the like in a
welding process can be reduced; the
electromagnetic stirring effect of the exiting coil is beneficial to the flow of the
metal in the furnace
hearth and the
thinning of a
grain structure of the welding beams, so that the
porosity and the
cracking rate of the welding beams can be reduced, the
structure property of a
welding joint is improved, an arc paraxial
welding process of the laser consumable
electrode can be optimized, and wide market prospect is realized.
