description The invention relates to an air suction and exhaust pipe structure and a welding method thereof. The air suction and exhaust pipe structure comprises a copper pipe, an iron cold heading piece and a stainless steel pipe, the upper part of the stainless steel pipe is provided with a sleeving opening, the copper pipe is nested in the sleeving opening, the copper pipe and the sleeving opening are fixed through furnace brazing, the iron cold heading piece is arranged on the stainless steel pipe in a sleeving mode, and the iron cold heading piece and the stainless steel pipe are fixed through furnace brazing. The stainless steel pipe is used as a main body of an air suction and exhaust pipe, and the lower end of the copper pipe is nested in the sleeving opening in the upper part of the stainless steel pipe in an interference manner, so that it is ensured that no rusting problem occurs in the use process of the air suction and exhaust pipe, the use stability and the service life of the air suction and exhaust pipe a
