Abstract
The composition of metal powder core of said invented surfacing welding rod is formed from (wt%) Co: 7-46%, Ni: 3-28%, Mo: 0-30%, Fe-Mo: 0-40%, W: 0-40%, Fe-W: 0-46%, Ti: 0-6%, Al: 0-4%, RE: 0-2%, Te: 0-2%, Se: 0-1.5%, Cr: 0-1%, and the rest is Fe power, Said welding rod possesses excellent welding property, after welding its hardness is not high, so that it is favourable for mechaical machining, and its aged hardness can be up to HRC 65-67, and the deposited metal does not produce crack, can be used to make and repair high-performance super-hard die, roller, valve and cutting-tool, etc..
Description
A kind of aged hardened toolsteel tungsten argon arc welding metal powder core surfacing welding rod belongs to metal powder core solder wire manufacturing technology field.
Age hardening tool steel is meant to have the typical tool materials characteristic, but do not resemble existing general tool steel and separate out the generation post-curing by carbide, but separate out promptly usually said timeliness, a kind of novel tool materials of acquisition high rigidity and heat resistance by intermetallic compound.The age hardening tool steel phosphorus content is extremely low, and is not high in as-quenched hardness, carries out machining easily, and hardness increases substantially after the timeliness, can be used for the manufacturing of high hardness wear-resisting part.But, influenced the practical application of this kind steel alloy in industrial production because age hardening tool steel needs vacuum metling, material price costliness, forgeability not ideal.
Built-up welding is to apply the technical process that one deck has the deposited metal of property such as wear-resisting, heat-resisting, corrosion-resistant or changes spare part outside measurement with welding method at piece surface heap.How making piece surface obtain high rigidity, high tenacity, high red hardness and have the overlay cladding of excellent abrasive resistance, is key issue anxious to be solved at present.But traditional high-hardness wear-resisting bead welding wire and welding rod all is to make metal strengthening by separating out of carbide at present, because its phosphorus content height, deposited metal toughness is very poor, very easily crack, and hardness do not satisfy the requirement of using yet.
The objective of the invention is at problems of the prior art, a kind of high rigidity, high tenacity, high red hardness are provided and have the aged hardened toolsteel tungsten argon arc welding metal powder core surfacing welding rod of excellent abrasive resistance.
Feature of the present invention is that the weight proportion of various powders in the metal-powder-core is: Co:7～46%, Ni:3～28%, Mo:0～30%, Fe-Mo:0～40%, W:0～40%, Fe-W:0～46%, Ti:0～6%, Al:0～4%, RE:0～2%, Te:0～2%, Se:0～1.5%, Cr:0～1%, all the other are the Fe powder, RE is a mishmetal, has at least a kind of non-vanishingly in each optional ingredient, and it is 30～52% that the percentage by weight that the powder core accounts for welding wire promptly adds the powder coefficient.
This welding wire deposited metal composition (weight %) is: C :≤0.03%, and Co:3～20%, Ni:1～14%, Mo:3～16%, W:5～25%, Ti:0～2%, Al:0～1%, RE :≤0.06%, Te :≤0.05%, Se :≤0.05%, Cr :≤0.5%, Mn :≤0.5%, Si≤0.5%, P :≤0.02%, S :≤0.02%, surplus is Fe.
Welding wire adopts the powder core wire common process to make, and the welding wire crust is selected high-quality mild steel steel band for use, and welding wire powder core is mixed in proportion by various metal powders, by the welding wire forming machine metal powder is wrapped in the steel band, and adopts drawing machine to make welding wire reduce to the use diameter.In welding wire manufacturing process, the employing ultrasonic wave cleans greasy dirt, corrosion and the moisture of removing steel strip surface, and the strict uniformity that adds powder coefficient and powder core material of controlling, and reduces the source and the content of impurity such as C, S, P to greatest extent.
Aged hardened toolsteel tungsten argon arc welding metal powder core surfacing welding rod provided by the invention, splash during welding little, appearance of weld is attractive in appearance.Surfacing layer metal has the typical tool materials characteristic, and postwelding is difficult for cracking under the fast speed cooling condition, hardness is HRC about 45, hardness increases substantially after the timeliness, can reach HRC 65～67, the non-notch notched bar impact strength is about 30J, red hardness was higher than traditional high-speed steel when toughness was identical, be heated to 650 ℃ the insulation 4 hours after hardness HRC be about 60, anti-temper softening is higher about 100 ℃ than traditional high-speed steel, it is bad to have overcome traditional high-hardness wear-resisting bead toughness of material preferably, the deficiency that crack resistance difference and hardness are not high, but also have better red hardness.This welding wire can be used for manufacturing and the reparation that the superhard mould of high-performance, roll, valve and cutter etc. require high rigidity, high tenacity, high-wearing feature and red hardness part.Also can be used as hot spraying powder core wire uses.
