Abstract
The invention discloses it is a kind of for macrotype hard alloy cutter welding, have and good wet effect and the novel solder flux of weld seam can be protected, be made of the cubond of weight percent 75 ~ 85% and 15 ~ 25% silver solder；Preferably, cubond is QJ301, silver solder QJ102, weight percent is preferably 80%, 20%；Solder flux of the invention not only spreads that wetability is best, but also the time soaked keeps permanent, can preferably protect weld seam not oxidized, and welding can also be promoted to be rapidly completed, and reduces weld interval, guarantees welding quality.
Description
Technical field
The present invention relates to a kind of hard alloy flux for solder, especially a kind of macrotype hard alloy cutter welding weldering
Agent.
Background technique
During carbide quartz welding, the effect of solder flux is: 1, assisting heat transfer；2, the oxidation around weld seam is removed
Object；3, it reduces and is soldered material surface tension；4, the greasy dirt for being soldered material surface is removed, bonding area is increased；5, it prevents again
Oxidation.In addition, it is also contemplated that two important technology indexs of solder flux: the wetability and volatilization temperature of solder flux.The two technologies refer to
Mark directly influences the mobility and welding quality of solder.
When welding macrotype hard alloy cutter, generally common HS221 spelter solder and QJ301 cubond.Macrotype hard closes
The golden Welding of cutters warm time is longer, longer in 400 ~ 600 DEG C of residence times, causes cubond before there is not thawing
Just there are hardening and flavescence oxidative phenomena, affects the wetting qualities of solder flux.Alloy blade also has oxide simultaneously；When cutter weld seam
When reaching 700 ~ 800 DEG C of solder flux melting temperature, these oxides can hinder the flowing of solder flux, influence welding quality.And work as weld seam
When temperature reaches 850 DEG C of melt temperature of spelter solder, solder flux has volatilized.
Summary of the invention
For the deficiency of existing macrotype hard alloy cutter welding solder flux, providing one kind has good wet effect and energy
Enough protect the novel solder flux of weld seam.
Macrotype hard alloy cutter welding solder flux of the invention, by the cubond of weight percent 75 ~ 85% and 15 ~
25% silver solder composition.
Preferably, the cubond is QJ301, the silver solder is QJ102.
As further preferred, the weight percent of the cubond and silver solder is respectively 80%, 20%.
Since hard alloy cutter is larger, in order to guarantee welding quality, cutter heating is needed to reach the welding temperature of solder
When time for welding it is longer, i.e., the time welded within 800 ~ 950 DEG C of time is longer, can guarantee weld seam in this temperature
The mobility of wetability and solder.And the new solder flux that 75 ~ 85% cubond and 15 ~ 25% silver solder are sufficiently mixed, 500
DEG C start to melt diffusion, the enlarged-diameter 14mm at 900 DEG C, it is also HS221 spelter solder in this temperature that diffusion area is maximum
Fusion temperature.At 950 DEG C, solder flux slowly volatilizees, and wetting range is slowly reduced.Therefore, the diffusion of flux of the invention
Wetability is best, and the time soaked keeps more permanent, can preferably protect weld seam not oxidized；Also welding can be promoted fast
Speed is completed, and weld interval is reduced, and guarantees welding quality.
