Abstract
The invention relates to a welding flux for stainless steel non-consumable electrode argon arc welding, which is a mixture formed by mixing chromic oxide, titanium dioxide and metal fluoride through physical action and is an active welding flux for the non-consumable electrode argon arc welding. The welding flux comprises, by weight, 50-60% of chromium oxide, 20-30% of titanium dioxide, and the balance of metal fluoride. The welding flux takes chromic oxide and titanium dioxide as main raw materials and metal fluoride as an auxiliary raw material. The metal fluoride is aluminum fluoride and calcium fluoride, wherein the weight ratio of the aluminum fluoride to the calcium fluoride is 1: 2. The flux of the invention simplifies the prior welding process, overcomes the defect of shallow fusion depth, and simultaneously realizes the aims of good effect, low energy consumption, high efficiency and low cost.
Description
The present invention is a kind of solder flux that is used for non-melting electrode argon arc welding of stainless steel, and it is through physical action, a kind of mixture that mixes with chrome green, titanium dioxide and metal fluoride.
Non-melting electrode argon arc welding occupies an important position in the industry in welding, it have protect, welding process is stable, the welding scope is wide, the smooth series of advantages such as smooth, specious of joint.But, when soldering stainless steel, because the reduction of sulphur, oxygen content in the stainless steel, in welding process, do not have sufficiently high [S], [O] in the reaction of welding chemical metallurgy with steel in alloying element (Fe, Mn etc.) and impurity element (Ca, Al etc.) be combined into dystectic oxide and sulfide and enter welding slag, on the contrary, the element of these low ionization energy can evaporate and enter into electric arc.And the mean temperature of electric arc and arc-plasma are formed direct relation are arranged in the welding process, in general, the electric arc mean temperature be Tg=1000Ui (℃), Ui is the ionization energy of various atoms in the arc atmosphere.
K | Na | Ca | Si | Mg | Fe | Ti | C | O | F | |
Ui(ev) | 4.3 | 5.1 | 6.1 | 8.7 | 7.61 | 7.83 | 6.1 | 11.2 | 13.5 | 17.4 |
It is as shown in the table, because the elements vaporization of these low ionization energy enters into electric arc, causes electric arc to be dispersed, and temperature reduces.So cause when the non-melting electrode argon arc welding soldering stainless steel, fusion penetration is superficial, welding efficiency is low.
The objective of the invention is provides a kind of solder flux that is used for non-melting electrode argon arc welding of stainless steel in order to overcome deficiency of the prior art, and it makes when the non-melting electrode argon arc welding soldering stainless steel, realize power consumption less, good result of use such as efficient height, cost be low.
The objective of the invention is to realize by following measure:
This kind is used for the solder flux of non-melting electrode argon arc welding of stainless steel, it is characterized in that the formula constituent of this solder flux, and the composition of this solder flux and proportioning be by weight percentage, chrome green 50%-60%, and titanium dioxide 20%-30%, all the other are metal fluoride.This kind solder flux is a primary raw material with chrome green, titanium dioxide, and metal fluoride is an auxiliary material.Metal fluoride is aluminum fluoride and calcirm-fluoride, and wherein the part by weight of aluminum fluoride and calcirm-fluoride is 1: 2.Add closed container together after above-mentioned kind raw material mixed in proportion, carry out ball milling then, the ball milling time is 24 hours.Be 300 purpose sieve by granularity then.Before welding work pieces, earlier that this solder flux and solvent is even, then with brush after place to be welded is coated with the very thin solder flux of last layer, weld again and get final product.
In welding process, oxide is (as TiO in the solder flux
2, Cr
2O
3Deng) under the welding arc high temperature action, at first with steel in element reactions such as C, Si, generate CO, SiO
2, CO, SiO
2Then decomposite oxygen, because entering of oxygen makes the surface tension of liquid metal bath reduce.Under the effect of liquid metal flow behavior, electric arc gos deep into the molten bath more, and penetration capacity increases greatly.On the other hand, oxide on the molten pool metal surface, around the electric arc and sulfide decompose, and O, S enter the arc column periphery, catch the electronics at a slow speed of arc column periphery, thereby compression arc has more improved arc current density, cause electric arc more concentrated, thereby improved fusion penetration.
The present invention has played beyond thought effect through using in the austenitic stainless steel welding, very strong raising fusion penetration effect is arranged.Under identical welding condition, compare with traditional non-consumable gas shielded arc welding, can improve fusion penetration 1-2 doubly, through test, the mechanical property of joint is not less than common non-melting electrode argon arc welding simultaneously.
Below with reference to embodiment the present invention is further described:
Embodiment 1 claims chrome green 50 grams, titanium dioxide 20 grams, aluminum fluoride 10 grams, calcirm-fluoride 20 grams, pours into after the mixing in the ball mill, carries out ball milling, and the ball milling time is 24 hours, takes out the back with 300 purpose sieve, both has been the solder flux product.150 amperes of welding currents, speed of welding 7m/h under the technological parameter that weldingvoltage is 10 volts, uses the stainless steel material that this kind solder flux can a through welding 8mm, and general T IG weldering with this technological parameter once can only through welding 3mm stainless steel material.
