Abstract
The utility model discloses a welding structure of a copper tube and a steel piece. The welding structure comprises the steel piece, the copper tube and a thin-wall copper tube. The steel piece and the copper tube are welded with an inner surface and an outer surface of the thin-wall copper tube respectively. The steel piece and the thin-wall copper tube are welded together through high-temperature copper base brazing filler metal. The copper tube and the thin-wall copper tube are welded together through copper phosphorus brazing filler metal. A section of the thin-wall copper tube is added at a brazing portion and used as a medium so as to form two welding lines and achieve welding of the copper tube and the steel piece. The welding structure is low in cost and good in air-tightness, does not require acid washing, and is good in workpiece uniformity and small in copper tube grains.
Description
Technical field
The utility model belongs to welding technology field, relates in particular to the Welding Structure of a kind of copper tube and steel part.
Background technology
At present copper tube and steel part (steel pipe) braze-welded structure are general adopts directly that ginseng connects weldering, and its ginseng place of connecing only has weld seam one, because being subjected to its structural limitations, adopts only silver-base solder, brazing solder or high-temperature copper-based solder to weld.One: adopt the silver-base solder welding because the solder price is high, product does not have price advantage; Two: adopt strong solder, can only be used for flame welding or ratio-frequency welding weld, and need to coordinate scaling powder, need carry out pickling processes after its welding, after big for environment pollution and pickling, air-tightness is relatively poor; Three: adopt high-temperature copper-based solder, it welds uniformity, air-tightness is good, and intensity is high, but its welding temperature is high, is generally 1030 ℃～1050 ℃, can cause like this copper pipe crystal grain to become large, and mechanical performance descends.
The utility model content
The utility model is for the problem that exists in existing copper tube and steel part (steel pipe) Welding Structure, and as adopting the silver-base solder welding, because the solder price is high, product does not have price advantage; Adopt strong solder, can only be used for flame welding or ratio-frequency welding weld, and need to coordinate scaling powder, need carry out pickling processes after its welding, after big for environment pollution and pickling, air-tightness is relatively poor; Adopt high-temperature copper-based solder, its welding uniformity, air-tightness are good, and intensity is high, but its welding temperature is high, is generally 1030 ℃～1050 ℃, can cause like this copper pipe crystal grain to become large, and degradation under mechanical performance proposes the Welding Structure of a kind of copper tube and steel part.
The utility model is achieved in that the Welding Structure of a kind of copper tube and steel part, and described Welding Structure comprises: steel part, copper pipe, thin-wall copper pipe;
Steel part and copper pipe respectively with the inside and outside surface soldered of thin-wall copper pipe together.
Further, the welding position adds one section thin-wall copper pipe as medium.
Further, described steel part and thin-wall copper pipe adopt high-temperature copper-based solder to weld together.
Further, described copper pipe and thin-wall copper pipe adopt copper phosphorus scolder to weld together.
The copper tube that the utility model provides and the Welding Structure of steel part are mainly to add one section thin-wall copper pipe as medium at the soldering position, thereby form the twice weld seam, realize the welding of copper pipe and steel part, this infrastructure cost is low, and air-tightness is good, without pickling, the workpiece high conformity, copper pipe crystal grain is little.
Description of drawings

The copper tube that the utility model provides and the Welding Structure of steel part mainly are comprised of steel part 1, copper pipe 2 and thin-wall copper pipe 3.Joining with steel part 1 place of connecing at copper pipe 2 adds one section thin-wall copper pipe 3 as medium, make its soldering position formation twice weld seam, namely first steel part 1 and thin-wall copper pipe 3 are carried out soldering, its scolder adopts high-temperature copper-based solder, again thin-wall copper pipe 3 and copper pipe 2 are carried out soldering, its scolder adopts copper-phosphorus brazing alloy, utilizes two kinds of scolder characteristics, and two kinds of scolder melting temperatures are poor, admittedly adopt staged welding mode to form overall structure.
The specific embodiment one:
According to shown in Figure 1, the copper tube that the utility model provides and the Welding Structure of steel part, it mainly is comprised of steel part 1, copper pipe 2 and thin-wall copper pipe 3.In this structure, carry out gas protecting soldering in steel part 1 endoporus of first thin-wall copper pipe 3 matched in clearance being packed into, its scolder adopts high-temperature copper-based solder, then copper pipe 2 matched in clearance is packed into carry out the secondary soldering in thin-wall copper pipe 3 endoporus, and its scolder adopts copper phosphorus scolder.
According to shown in Figure 2, the copper tube that the utility model provides and the Welding Structure of steel part, it is mainly by steel part 1, and copper pipe 2 and thin-wall copper pipe 3 form.In this structure, first thin-wall copper pipe 3 close-fitting traps and steel part 1 outer wall are carried out gas protecting soldering, its scolder adopts high-temperature copper-based solder, then copper pipe 2 close-fitting traps and thin-wall copper pipe 3 outer walls are carried out the secondary soldering, and its scolder adopts copper phosphorus scolder.
The copper tube that the utility model provides and the Welding Structure of steel part are mainly to add one section thin-wall copper pipe 3 as medium at the soldering position, thereby form the twice weld seam, realize copper pipe 2 and steel part 1 welding, this infrastructure cost is low, and air-tightness is good, without pickling, the workpiece high conformity, copper pipe crystal grain is little.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
