Compared with a single-strand braze welding wire, the multi-strand braze welding wire has the advantages that the specific surface area of the welding wire can be remarkably increased, the heat conduction efficiency of the welding wire is high, the braze welding wire is evenly melted, the melting time is short, the braze welding quality and the production efficiency are remarkably improved, and meanwhile, long-time continuous heating over certain heat-labile tools (such as polycrystalline diamond composite (PDC) tools ) are avoided, thereby achieving a work piece protecting effect; brazing flux is coated on the welding wire, thereby avoiding the trouble of brazing flux adding in the heating process; the brazing flux can be filled in a clearance between the single wires, thereby increasing the adhesive force of the brazing flux over the braze welding wire. The areas of the cross sections of the multiple single wires intertwisted together are different, so that the clearance between the single wires can be changed, the requirement of increasing the content of the brazing flux between the single wires is satisfied, and the aim of freely adjusting the proportion of ingredients of composite brazing filler metal is achieved.
Description
Technical field
The utility model relates to welding wire, especially relates to a kind of multiply cored solder wire of soldering better effects if.
Background technology
Brazing material is widely used in metal of the same race, dissimilar metal and metal and is connected in the technology with soldering between nonmetal, has that heating-up temperature is low, little to the mother metal heat affecting, technology simple, the characteristics of easy operating.
Generally, soldering connects heating-up temperature and strict requirement is all arranged heat time heating time, and this just makes brazing material must possess good pre-arcing characterisitics.Traditional cored solder wire is the circular section of sub-thread; For the cored solder wire of diameter between 2-4mm, because specific area is little, receive thermal velocity slow during use; In heating process, often will spend the long time could melt, thereby has reduced its melting rate in brazing process.In work progress,, also have operating personnel to impel its quick fusing, but this method is than the deterioration that is easier to cause the mother metal performance through the method that improves heating-up temperature for improving soldering efficient.In addition, in the heating process of soldering, also need butt welded seam constantly to add brazing flux, active to increase solder, remove the oxide on solder and mother metal surface, improve brazing manufacturability.Traditional coating cored solder wire is employed in the method for chevilled silk (cored solder wire) surface adhesion brazing flux, has exempted manually adding the loaded down with trivial details of brazing flux; Obtained reasonable result of use; But because the surface adhesion of chevilled silk is poor, and brazing flux itself is more crisp, thus with the coating cored solder wire of brazing flux in processes such as manufacturing, packing, transportation and use, run into collision, during the situation of being out of shape; Brazing flux is prone to peel off, big limitations the serviceability and the range of application of coating cored solder wire.
Summary of the invention
The purpose of the utility model is to provide that a kind of specific area is big, production technology simple, the multiply cored solder wire of welding wire surface coating strong adhesion.
For realizing above-mentioned purpose, the utility model can be taked following technical proposals:
The described multiply cored solder wire of the utility model comprises welding wire, and said welding wire is by at least two bursts of stranded forming of monofilament.
Be coated with brazing flux on the said welding wire, removed from and added the loaded down with trivial details of brazing flux in the heating process; Brazing flux can be full of in the gap between the monofilament, has increased the adhesive force of brazing flux to cored solder wire.
The area of a plurality of monofilament cross sections that twist together is different, can change the gap between the monofilament, satisfies the brazing flux content that improves between the monofilament, reaches the purpose of freely adjusting the composite soldering component ratio.
The advantage of the utility model is:
1,, can enlarge markedly the specific area of welding wire, because the specific area of welding wire is big more with respect to the sub-thread cored solder wire; The welding wire of unit volume and the heat transfer area of thermal source are just big more, and the heat conduction efficiency of welding wire is just high more, and the fusing of cored solder wire is just even more; Fusing time is just short more; The corresponding quality and the production efficiency that just can significantly improve soldering has been avoided long-time, the lasting heating to some thermo-labile instrument (like the PDC instrument) simultaneously, has played the effect of protection workpiece.Multiply cored solder wire with round cross section is an example; Sub-thread cored solder wire with respect to composition of the same race, same quality; The specific area of multiply cored solder wire be it
doubly; Wherein, N is the monofilament quantity of multiply cored solder wire, and n>=2.
If 2 apply brazing flux on the welding wire that the multiply monofilament is twisted into, with respect to the sub-thread cored solder wire,, increased the bond area of brazing flux because specific area is bigger, add multiply cored solder wire complex surfaces profile, can significantly improve the bond strength of brazing flux and cored solder wire; In addition, fill brazing flux in the gap between monofilament and also can improve the brazing flux content in the welding wire, even cored solder wire crust brazing flux peels off, the brazing flux in the welding wire gap still can play the protective effect to the fusing solder.
3, the multiply cored solder wire is for infusibility refining alloy and difficult-to-cut alloy (like the brazing filler metal alloy of titaniferous); Can use the compound mode of machinery to prepare; At first calculate the monofilament of processing heterogeneity through the proportioning of composition; Monofilament ratio with certain is twisted into the multiply silk, has satisfied the content requirement of multiply cored solder wire to whole composition, the new method that provides a kind of ratio to be easier to realize for the preparation of composite soldering.
