I-Welding yinkqubo apho izinto ze-workpieces zidityaniswe (ezifanayo okanye ezahlukeneyo) zidityaniswe ngokufudumeza okanye uxinzelelo okanye zombini, kunye okanye ngaphandle kokuzalisa izinto, ukwenzela ukuba izinto ze-workpieces ziboshwe phakathi kwe-athomu ukwenza uqhagamshelwano.Ke ngawaphi amanqaku aphambili kunye nesazisowelding steel stainless?
Yiyiphi i-electrode esetyenziselwa i-welding steel stainless?
I-1.I-electrodes yensimbi engenasici ingahlulwa ibe yi-chromium i-electrode yensimbi engenasici kunye ne-chromium-nickel yensimbi engenasici.Ezo ntlobo zimbini zee-electrode ezihlangabezana nomgangatho wesizwe ziya kuvavanywa ngokwemigangatho yesizwe ye-GB/T983-2012.
I-2.I-Chromium insimbi engenasici ine-corrosion resistance resistance (i-asidi i-oxidizing, i-asidi ye-organic, i-cavitation) ukumelana nobushushu kunye nokumelana nokugqwala.Idla ngokukhethwa njengezixhobo zesixhobo sesikhululo samandla, ishishini lamachiza, i-petroleum njalo njalo.Nangona kunjalo, isakhono se-weld ye-chromium yensimbi engenasici siqhelekile, kwaye kufuneka ilumke ihlawulwe kwinkqubo ye-welding, iimeko zonyango lobushushu kunye nokukhethwa kwee-electrode zokuwelda ezifanelekileyo.
I-3.I-Chromium-nickel i-electrodes yensimbi engenasici ine-corrosion resistance resistance kunye nokumelana ne-oxidation, kwaye isetyenziswa ngokubanzi kwimichiza, isichumisi, i-petroleum, kunye nokuveliswa koomatshini bezonyango.Ukuze kuthintelwe i-intergranular corrosion ngenxa yokufudumeza, i-welding current ayifanele ibe nkulu kakhulu, malunga ne-20% ngaphantsi kwe-carbon steel electrode. kufanelekile.
Amanqaku e-Stainless Steel Welding kunye neSaziso
Unikezelo lwamandla oluneempawu zangaphandle ezithe nkqo luyamkelwa, kwaye i-polarity elungileyo isetyenziselwa i-DC (intambo ye-welding iqhagamshelwe kwipali engalunganga)
1.Kufanelekile ngokubanzi ukuwelda intsimbi yentsimbi ebhityileyo ngaphantsi kwe-6mm.Ineempawu zemilo ebalaseleyo ye-welding kunye ne-welding deformation encinci.
I-2.I-gas yokukhusela i-argon kunye nokuhlambuluka kwe-99.99%.Xa i-welding yangoku i-50 ~ 150A, izinga lokuhamba kwegesi ye-argon yi-8 ~ 10L / min, xa ikhoyo ngoku i-150 ~ 250A, isantya sokuhamba kwegesi ye-argon yi-12 ~ 15L / min.
3.Ubude obuphumayo be-electrode ye-tungsten ukusuka kwi-nozzle ye-gas ngokukhethekileyo i-4 ~ 5mm.Yi-2 ~ 3mm kwiindawo ezikhuselwe kakubi ezifana ne-fillet welding, kunye ne-5 ~ 6mm kwiindawo apho i-slot inzulu.Umgama ukusuka kwi-nozzle ukuya emsebenzini awukho ngaphezu kwe-15mm.
4. Ukuze ukhusele i-welding porosity, ukuba kukho i-rust kunye ne-oil stains kwiindawo ze-welding, kufuneka ihlambuluke.
5. Ubude be-arc welding kukhethwa ukuba yi-2 ~ 4mm xa udibanisa intsimbi eqhelekileyo, kunye ne-1 ~ 3mm xa u-welding steel stainless.Ukuba lide kakhulu, umphumo wokukhusela awuyi kuba mhle.
6. Xa i-butt-bottoming, ukuze kuthintelwe umva we-weld bead engezantsi ekubeni i-oxidized, umva kufuneka ukhuselwe ngegesi.
7. Ukuze wenze i-argon gas ikhusele kakuhle i-welding pool kwaye iququzelele ukusebenza kwe-welding, umgca ophakathi we-electrode ye-tungsten kunye ne-workpiece kwindawo ye-welding kufuneka igcine i-angle ye-80 ~ 85 °, kunye ne-angle phakathi ucingo lokuzalisa kunye nomphezulu we-workpiece kufuneka ibe yincinci kangangoko.Ngokuqhelekileyo, malunga ne-10 °.
8. Ukuthintela umoya kunye nokungena komoya.Apho kukho umoya, nceda uthathe amanyathelo okuthintela inethi, kwaye uthathe amanyathelo afanelekileyo okungenisa umoya ngaphakathi endlini.
