Abstract
The invention relates to a manufacturing method of the solder wire of a welding material, which belongs to the technical field of the manufacturing method of the welding material. The manufacturing method comprises the following steps: pure Sn or Sn-based alloy solder is melted into ingots, core welding material is pressed into the alloy ingots, and solder wires are produced through drawing. The solder wire manufactured by the method solves the problem that the solder wires of a part of brittle soldering material are difficult to be prepared, and various solder wires can be prepared according to the actual needs; the produced solder wire has excellent drawing property, welding operation performance and transfer performance, the welding spot is bright after welding, therefore, the solder wire can replace the multi-core solder wire.
Description
Technical field
The invention belongs to welding material preparation method technical field, relate to a kind of tin wire production method of welding material.
Background technology
Cored solder wire is mainly used in manual iron soldering, and traditional medicine core solder silk is the inside that flux is sealed in advance the brazing filler metal alloy blank, and the center of making through drawing is the soldering flux core, and the outside is enclosed with the silk material of soft solder alloy; In addition, the sky of solder(ing) paste is disconnected and improve the efficient that draws in the solder stick, and the someone has worked out multicore solder manufacture craft, makes the multicore solder stick.And, being difficult to make solder stick by this technology for fragility welding material SnBi and SnBiCu series solder, very inconvenience of operation is so lack in welding profession and this type of solder(ing) paste, the supporting solder stick product of soldering tin bar at present.
Summary of the invention
The present invention provides a kind of tin wire production method of welding material especially in order to overcome deficiency of the prior art, and it both can be used for the solder stick making of fragility welding material, and the solder stick that also can be used for the welding material of conventional usefulness is made.The manufacture craft process is simple, has reduced the brittle failure rate of welding wire in drawing process, has improved drawing property, welding operation performance and the transportation performance of solder stick.
The present invention is achieved by the following technical solutions: solder stick comprises inner core welding material and outer welding material, outer welding material can be selected pure Sn or Sn base solder for use, the inner core welding material can be according to the purposes and the needs of product, select all kinds of solder(ing) pastes, can add solder(ing) paste by in SnBi, SnBiCu, SnBiAg, SnAg, SnZn, SnCu, SnAgCu, SnSb, the SnZnBi alloy powder more than one and mix, mix well and form.
Outer welding material and inner core welding material mass ratio are 1:0.5～4.5, and outer layer thickness is a minimum of a value not expose the inner core welding material; By regulating the ratio of inner core welding material and outer welding material
Can be as required in the inner core welding material, adding mass percent is to be no more than 5% high conductivity, the metal dust of high-termal conductivity, as Ag, Cu, Ni, Ti one or more, be used for optimizing the performance of solder joint.Described solder stick can be made different size and shape of cross section, can regulate the ratio of inner core welding material and outer welding material, makes the solder stick of different components.
In the preparation process, to take by weighing pure Sn material or Sn base alloy earlier, it is smelted into ingot as outer welding material; Inner core welding material with proper ratio is pressed in the alloy pig by mechanical-hydraulic equipment again, and through drawing and the center of making is the solder(ing) paste core, the outside is enclosed with the soft solder alloy silk of pure Sn or Sn base alloy.
The invention has the beneficial effects as follows: the tin silk that has solved some fragility soldering tin materials is difficult to be mixed with the problem of solder stick, and can prepare various welding wires according to actual needs.This tin wire production method is workable, and technology is simple, and the solder stick of making has good drawing property, welding operation performance and transportation performance, and the full light of the solder joint that welds out, alternative multicore solder stick; Also can make the solder stick of heterogeneity by regulating the ratio of inner core solder(ing) paste and exocuticle tin material; Can add high conductivity, high-termal conductivity metal powder such as Ag, Cu, Ni, Ti etc. as required in the tinbase solder(ing) paste in addition, thereby optimize the performance of solder joint; And the granularity of solder(ing) paste does not have specific (special) requirements, thereby improves the utilization rate of solder powder.
