Summary: | The invention relates to a welding method of CO2 gas shielded welding for a solid welding wire with the diameter of phi 1.6. The welding method comprises the step of welding a workpiece by a way of vertical position welding or horizontal position welding, wherein the welding process sequentially comprises the steps of welding a base layer, welding a filler layer and welding a cover surface layer, and the thickness of the welded workpiece is not less than 30mm; when the workpiece is welded in the way of vertical position welding, the welding current is 150-180A, and the arc voltage is 20-24V when the base layer is welded; the welding current is 160-240A, and the arc voltage is 20-28V when the filler layer is welded; the welding current is 150-200A, and the arc voltage is 20-26V when the cover surface layer is welded; when the workpiece is welded in the way of horizontal position welding, the welding current is 180-220A, and the arc voltage is 23-26V when the base layer is welded; the welding current is 230-280 |
