Abstract

The invention relates to the technical field of welding equipment and discloses micro-beam precise vertical argon arc welding forming equipment and a welding method, wherein the micro-beam precise vertical argon arc welding forming equipment comprises a welding machine, a welding gun, a fixing seat and a blowing sleeve, wherein the fixing seat is used for supporting the welding gun, a connecting seat is rotatably arranged on the outer surface of the fixing seat through a torsion rotating shaft, the welding gun is fixedly arranged on the connecting seat, the blowing sleeve is used for blowing out protective gas from a welding end of the welding gun, the blowing sleeve is fixedly sleeved on the outer side of the welding end of the welding gun, a gap is reserved between the blowing sleeve and the outer surface of the welding end of the welding gun, and an air inlet pipe is fixedly arranged on the outer surface of the blowing sleeve in a penetrating manner. When the flow of the shielding gas in the air inlet pipe is too fast and the flow is too large, the adjusting plate is stirred towards the inner side of the hollow box through the sleeve and the connecting frame, so that the cross section of the air inlet pipe is reduced by the adjusting plate, the flow of the shielding gas is reduced, and the phenomenon that the welding stability is influenced by gas turbulence generated in a welding area is avoided.
