Embodiment Construction

[0016] The present invention is described in further detail by the following examples.

[0017] see figure 1 As shown, the welding method between the thin-walled stainless steel bellows 4 and the copper joint 1 is as follows: firstly clean the connecting portion of the thin-walled stainless steel bellows 4 and the connecting portion of the copper joint 1 and apply silver solder paste; The connecting part of the thin-walled stainless steel bellows 4 is inserted into the connecting part of the copper joint 1, and the outer wall of the copper joint 1 away from the connecting part is sprayed with a flame spray gun to heat the copper joint 1; when the connecting part of the copper joint 1 and the thin-walled stainless steel bellows 4 is indirectly heated to When the temperature is within the temperature range of 750°C-860°C (this temperature range is the melting temperature range of the silver electrode), the operator slowly puts the silver electrode along the exposed part 2 where ...

Abstract

The invention discloses a welding method of a thin-walled stainless steel tube and a copper tube part, which can lead the thin-walled stainless steel tube and the copper tube part to form a permanent fastening and sealing connecting structure at the connecting part. The welding method has simple process, the steps of the process thereof are that: (1) the connecting part of the thin-walled stainless steel tube and the copper tube part is cleaned, silver welding paste is coated at the connecting part of the thin-walled stainless steel tube and the copper tube part which is clean; (2) the connecting part of the thin-walled stainless steel tube is inserted in the connecting part of the copper tube part, the outer wall of the copper tube part is heated; (3) when the connecting part of the copper tube part and the thin-walled stainless steel tube is indirectly heated to the temperature range of 750 DEG C to 860 DEG C, a silver welding strip is arranged along the exposed position of the connecting part of the thin-walled stainless steel tube and the copper tube part, the silver welding strip is melted by utilizing the heat stored in the copper tube part, and the welding connection of the thin-walled stainless steel tube and the copper tube part can be completed after the cooling. The welding method can be widely applied in cold and hot water supply pipelines of various tap water supply pipelines and water heaters.

Description

technical field [0001] The invention relates to the technical field of welding thin-walled stainless steel pipes and copper, in particular to a welding method for thin-walled stainless steel pipes and copper pipe fittings. Background technique [0002] At present, in the tap water supply pipeline or the cold and hot water supply pipeline of the water heater, the sealing connection structure between the thin-wall stainless steel bellows and the copper pipe fittings is basically a nut fastening connection structure, that is, the thin-wall stainless steel The connection end of the bellows is punched through a special mold, and then a sealing rubber gasket is placed at the connection, and the nut that is movable on the bellows is screwed into the external thread of the connection part of the copper pipe and tightened to complete the thin-walled stainless steel bellows and copper. Sealed connection of pipe fittings. In most cases, these thin-walled stainless steel bellows and th...
