① craft solder (MMA)
Craft solder is a kind very pervade, apply easily solder method. The length of electric arc relies on the person's hand to undertake recuperating, its resolution is mixed at welding electrode between workpiece the large and small of aperture. Together, when regarding electric arc as carrier, welding electrode also is data of welding line fill. This kind solders way is very simple, can use solder simply all data. About outdoor apply, it has wonderful adaptability, even if is applied in underwater also be no problem. In electrode solder, resolution of electric arc length the hand: at the person? Skip Qiao mu Mu of  of ぜ of wooden tablets or slips for writing of  Ke  illuminate? of be jealous of you also altered the length of electric arc. Below most circumstance, solder choose dc, electrode regards electric arc as carrier already, also regard welding line fill as the data together. Electrode by alloy or blame alloy metal core silk and welding rod coating are comprised, this coating safeguards welding line not to suffer airy to damage, a smooth and steady electric arc, it still brings about the formation of broken bits layer, safeguard welding line to make it shapes. Welding electrode can be titanium welding rod already, also can be alkalescent, this resolution is mixed at the ply of coating composition. Titanium welding rod solders easily, welding line is compressed and beautiful, and solder broken bits easily take out. If welding rod stores,time grows, be necessary from the beginning roast, because come from airy humidity,can be very fast in welding rod accumulate.
Welding wire of core of stainless steel medicine solders key and note
(1) chooses smooth character to solder power source, reversal sex is chosen when dc solders. Apply general CO2 welder to be able to apply solder, but the pressure that sends filar annulus moves a pine a bit please.
(2) safeguards gas to be carbon dioxide gas commonly, aeriform discharge suits relatively with 20~25L/min.
(The interval between 3) solder mouth and workpiece with 15~25mm advisable.
(Does 4) doing extend length: ? Word astounded dusk adds the Chi that embrace Si 15mm is made an appointment with when?50A is the following, 20~25mm is made an appointment with when 250A above relatively appropriate.
② MIG/MAG solders
This is a kind of automatic gas safeguards arc welding to accept idea. In this kind of method, electric arc is in safeguard aeriform screen to fall smooth and steady between voltaic carrier tinsel and workpiece calorific, the tinsel that the machine sends serves as welding rod, melt falls in itself electric arc. Because MIG/MAG solders the good qualities of the versatility of the law and characteristic, up to now she remains the world to go up most extensive solder method, apply to alloy steel of steel, blame, low-alloy steel and tall alloy to be base data. This makes it becomes aspiration produce and of repair solder method. Should solder when steel, MAG can the request that satisfaction wants the light standard board with large 0.6mm only. The maintenance that applies here gas is active gas, be like carbon dioxide or gas mixture.
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 zephyr 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 hold to aeriform maintenance action.
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 is choosing dc still 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 ” of clean without any “ to welding line bath action. 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 exceed 15mm commonly to the interval of exercise.
