Abstract
The invention provides a kind of tube type alloy weld rod and production method thereof.This alloy electrode with copper pipe as welded tube and bonded metal, with the hard alloy particle is the hard phase, the wearability of its cementability and layer all is greatly improved, this kind welding rod also can be packed the hard alloy particle of different thicknesses in the copper pipe in proportion according to user's needs, production technology is simple, equipment investment is few, can satisfy user's requirement preferably.
Description
The present invention relates to a kind of tube type alloy weld rod and production method thereof, particularly a kind of employing copper material that is used for the welding of petroleum drilling and mining milling shoe, junk mill, keyway, expander, centralizer etc. is made the alloy electrode and the production method thereof of welded tube.
Present widely used tubular type cast tungsten carbide welding rod, be to be the hard phase with the casting carbon tungsten carbide particle, with the high-quality low carbon steel pipe is the alloy electrode of bonded metal, use this kind welding rod, its bonded metal is relatively poor to the cementability of hard phase, the wearability of its layer is also poor, and it is the welding rod of hard phase that this kind welded tube also should not be used to make with the hard alloy particle.In order to overcome above-mentioned shortcoming; people have designed a kind of sintering welding rod; this welding rod is that the carbide alloy fragment with different thicknesses adds and joins the strip welding rod that the copper powder sintering forms; but its production technology is complicated; need the blanketing with inert gas sintering, equipment investment is big, and power consumption is big; and main by from external import, need a large amount of foreign exchange of cost.
The object of the present invention is to provide a kind of tube type alloy weld rod and production method thereof.This welding rod is the bonded metal welded tube with copper, is the hard phase with the hard alloy particle, improves layer cementability and wearability to reach, and reduces equipment investment, produces simply purpose easy to use.
Solution of the present invention is: welding rod adopts copper pipe as welded tube and bonded metal, and hard is hard alloy particle mutually, can be the mixture of tungsten-cobalt alloy or tungsten-cobalt alloy and tungsten-cobalt-titanium alloy; These alloying pellets are tightly filled in copper pipe, the sealing of copper pipe both ends.The production method of this alloy electrode is that tungsten-cobalt alloy and tungsten-cobalt-titanium alloy are processed into particle and the evenly mixing that granularity is 0.177～6mm, wherein tungsten-cobalt-titanium alloy accounts for 0～20% of whole weight alloy, all the other are tungsten-cobalt alloy, can in different size and ratio mixed alloying pellet be packed in the copper pipe according to user's needs, jam-pack, then the copper pipe two ends are shut, wherein copper pipe accounts for 35～45% of whole welding rod weight, the percentage by weight of alloying pellet is 55～65%, and the diameter of copper pipe is 6～12mm, its copper material can be a brass, also can be copper-nickel alloy.
The invention has the advantages that and adopt copper pipe as welded tube and bonded metal, can improve cementability to the hard phase, adopt hard alloy particle as the hard phase, can improve the wearability of layer, this kind welding rod also can be packed the hard alloy particle of different thicknesses in the copper pipe in proportion according to user's needs, production technology is simple, and equipment investment is few, can satisfy user's requirement preferably.
Optimum implementation of the present invention is:
With the alloy electrode that is used for the petroleum drilling and mining centralizer is example, and welded tube adopts diameter 10mm, wall thickness 1.2mm, the H of length 400mm
62Brass tube is processed into the particle that granularity is 0.177～3.5mm with tungsten-cobalt alloy, then it is filled in the copper pipe, and jam-pack, its percentage by weight are copper 35～45%, and tungsten-cobalt alloy 55～65% can use the sealing of copper pipe both ends at last.
The alloy electrode that is used for petroleum drilling and mining instrument junk mill is then selected diameter 12mm for use, wall thickness 1.5mm, the H62 brass tube of length 400mm, to be processed into granularity be the particle of 4～6mm and fill in the copper pipe with tungsten-cobalt alloy, and its percentage by weight still is a copper 35～45%, tungsten-cobalt alloy 55～65%.
The alloy electrode that is used for the oil fishing tool then need add an amount of tungsten-cobalt-titanium alloy particle, and its percentage by weight is a copper 35～45%, tungsten-cobalt alloy 44～52%, tungsten-cobalt-titanium alloy 11～13%.
