Of stainless steel solder method tutorial

Key of solder of stainless steel MIG reachs a note
(1) chooses smooth character to solder power source, reversal sex is chosen when dc (welding wire receives positive electrode) .
(2) chooses pure argon to enrage commonly (purity is 99.99%) or Ar+2%O2, discharge with 20~25L/min advisable.
(Does 3) report arc length spend: ? Suddenly Sun is worth Mo IG to solder, erupting commonly interim condition comes down to apply solder, voltage should adjust arc length to be in the degree of 4~6mm.
(4) the root of fangfeng: MIG solders to suffer the effect of wind simply, sometimes gentle breeze and produce air hole, so wind speed is in the place of 0.5mc above, ought to adopt windbreak measure.
(5) moistureproof: ? Yi Piao adds mail? to be necessary to defend work not be affected with damp be affected with damp, in order to maintain aeriform maintenance the effect.
③ TIG solders
Electric arc happens between the tungsten report welding wire in difficult frit and workpiece, the maintenance that applies commonly gas is pure argon gas, the welding wire that sends is not live, already can the hand sends, also can machinery sends, still have a few specific use criterion not demand sends welding wire. The data resolution that is soldered is to choose dc or alternating current: ? ∮ cover stretchs tight set of silk of electric welding of tungsten of Jian Li? is negative pole, because it has very deep solder to show ability, the steel that plants about differ sample is very appropriate, but do not have to welding line bath any " clean effect " . TIG solders the first advantage of the law is to be able to solder big data scope is wide, include ply to reach the workpiece of its above in 0.6mm, raw material includes alloy steel, aluminous, magnesian, copper to reach its alloy, grey mouth is cast-iron, general all sorts of dry, bronze, nickel, silver-colored, titanium and lead. Principal applied territory is the workpiece that ply waits for in soldering to be mixed thinly, in thicker sectional go up to as solder root solder apply.
Key of solder of stainless steel TIG reachs a note
(1) chooses the power source of straightforward external characteristic, positive electrode sex is chosen when dc (welding wire receives negative pole) .
(2) agrees with commonly solder laminosely under 6mm, have welding line to shape beautiful, solder the characteristic with small deflection.
(3) safeguards gas to be argon gas, purity is 99.99% . Should solder when electric current is 50~150A, argon throughput is 8~10L/min, when electric current is 150~250A, argon throughput is 12~15L/min.
(4) tungsten extremely from the length with aeriform crackajack nozzle, it is beautiful with 4~5mm, the place that needs in the cover sex such as horny solder is 2~3mm, be in the place with dark chamfer is 5~6mm, nozzle does not surmount 15mm commonly to working interval.
(5) enrages Kong Zhi to appear to avoid to solder, solder if place has ferruginous, smeary etc must arrange clean.
(6) solders electric arc length, solder when general steel, it is beautiful with 2~4mm, and solder when stainless steel, it is beautiful with 1~3mm, grow to safeguard the effect too bad.
(When render of 7) butt joint, the opposite that to avoid rock-bottom solder is oxidized, the opposite also needs to be realistic apply gas to safeguard.
(8) solders to make argon gas is safeguarded well bath, and facilitate the operation that apply solder, line of tungsten pole center and weld workpiece should defend 80~85 ° role commonly, fill welding wire and workpiece surface included angle should be used up the ground is little perhaps, order about for 10 ° commonly.
(9) the root of fangfeng and take a breath. Have the place of wind, wu adopts the measure that blocks a network please, and should adopt measure of appropriate take a breath indoors.
Stainless steel solders craft request
The provision before solder: 4Ply of need not open Mm crevasse, solder directly, bosseyed solder is appeared. 4 can not choose crevasse connect to welding line of butt joint of 6 Mm ply double-faced solder. 6 Mm above, open V or U commonly, x form groove.
Next: ? Welding wire of fill of courtyard obituary? undertakes oil and deoxygenate change a skin dividing. Solder in order to ensure quality.
Solder parameter: ?   adds the? that embrace Si tungsten pole diameter, arc length, electric arc voltage, solder speed, safeguard air current, nozzle diameter.
1, solder the crucial factor that electric current is figuration of resolution welding line. Data of general basis weldment, ply, shape of the degree of lip-rounding that reach slope comes of resolution.
2, basis of solder pole diameter solders resolution of voltaic large and small, electric current is bigger, the diameter is bigger also.
3, solder arc and electric arc film, arc length dimensions is made an appointment with 0.5 to 3mm, corresponding electric arc voltage is 8~10V.
4, solder fast: ? Chasm of palpitate of  of Xi ∈ money falls susceptibility of data of weldment of? of Si Di Gan, solder the element resolution such as azimuth and operation method.
