The invention discloses a
welding machine with a
welding fume multiple collecting and filtering mechanism and a filtering method, and relates to the technical field of
welding. The purposes of completely collecting
welding fume and preventing leakage are achieved. The welding
machine comprises a bottom plate, a sliding seat
assembly is fixedly connected to the outer wall of the top of the bottom plate, a filtering
assembly is fixedly connected to the outer wall of the top of the sliding seat
assembly, a vertical frame is fixedly connected to the outer wall of the top of the sliding seat assembly, a
transverse beam is fixedly connected to the outer wall of the top of the vertical frame, an air suction assembly is fixedly connected to the outer wall of the top of the
transverse beam, and an outer cover assembly is fixedly connected to the inner wall of one side of the
transverse beam. The filtering method of the welding
machine comprises the following steps of gas conveying, preliminary
ionization, deep filtering, waste
settling and gas discharging. By arranging a top cover, a folding cover, a bottom cover, the vertical frame and a supporting plate, a
closed space can be constructed for a welding area, the
closed space only has one outlet, namely, a gas outlet
pipe, when high-temperature
welding fume is generated, the high-temperature
welding fume rises to the gas outlet
pipe to be discharged out of the
closed space, and the
recovery efficiency of the welding fume is improved.
