Iindidi zeegesi ezikhuselayo
Igesi ezikhuselweyo ezisetyenziselwa i-laser welling yi-nitrogen (N2), iArgon (i-ARGON (i-ARGON), kunye ne-helium (yena). Ezi gesi zineepropathi ezahlukeneyo zomzimba kunye nekhemikhali, ezikhokelela kwiziphumo ezahlukeneyo kumthungo we-wel.
I-1. I-Nitrogen (N2)
I-N2 inommandla we-ions ophakathi, ophezulu kune-AR kwaye asezantsi kunaye. Phantsi kwesenzo se-laser, kuyo i-IIIRDE YOKUGQIBELA, UKUHLAZIYWA KOKUSETYENZISWA KWE-PLASMA LESS kunye NOKUFUNDA UKUSETYENZISWA KWE-Laser. Nangona kunjalo, i-nitrogen inokuphinda iphendule ngokulandelelana kunye ne-allomium ye-alloys kunye ne-carbon yensimbi kumaqondo obushushu, enza i-nitrides. Oku kunganyusa ubuchwephesha kwaye kunciphise ubunzima bomthungo we-Wold, buchaphazela kakubi iipropathi zayo. Ke ngoko, ukusetyenziswa kwe-naitrogen njengegesi yokukhusela izabelo ze-aluminium kunye ne-carbon ye-carbon steel ayicetyiswa. Kwelinye icala, i-nitrogen inokuphendula ngentsimbi engenasimo, yenza i-nitrides ephucula amandla okuphikisana kwe-weld. Ke ngoko, i-nitrogen ingasetyenziswa njengegesi yokukhusela ngenxa yentsimbi engenasibala.
I-2. I-Argon igesi (i-ar)
Igesi ye-Argon inamandla aphantsi kakhulu, okukhokelela kwinqanaba eliphezulu le-ionis phantsi kwesenzo se-laser. Oku akulunganga ukulawula ukwenziwa kwamafu ePlasma kwaye kunokuba nefuthe elithile ekusebenziseni kakuhle ii-lars. Nangona kunjalo, i-argon inendawo ephantsi kakhulu kwaye akunakulindeleka ukuba iphendule ngemali yekhemikhali ngeentsimbi eziqhelekileyo. Ukongeza, i-argon isebenza ngendleko. Ngapha koko, ngenxa yento yalo ephakamileyo, i-argon sinks ngaphezulu kwechibi le-weld, libonelela ngokhuseleko olungcono lwechibi le-weld. Ke ngoko, inokusetyenziswa njengegesi yokukhusela eqhelekileyo.
I-3. Irhasi yeHelium (Ye)
Igesi yeHelrium inamandla aphezulu, ekhokelela kwinqanaba lokuchithwa kwe-ions ephantsi kwesenzo se-laser. Ivumela ukulawulwa okungcono kweplasma yelifu, kwaye i-lars inxibelelane ngokufanelekileyo nezinyithi. Ngapha koko, i-helium inendawo ephantsi kakhulu kwaye ayihambi lula i-sccocictions kunye neentsimbi, zenza irhasi ebalaseleyo yokufikelelwa kwe-weld. Nangona kunjalo, iindleko ze-helium iphezulu, ngoko ayisetyenziswanga kwimveliso yezininzi zeemveliso. Ihlala isetyenziswa kuphando lwesayensi okanye kwiimveliso ezixabisekileyo zexabiso eliphezulu.

Iindlela zokwazisa igesi yokukhusela igesi
Okwangoku, zimbini iindlela eziphambili zokwazisa irhasi yokukhusela igesi: I-Off-Axis-I-Axis-Igesi ekhuselweyo, njengoko kubonisiwe kumzobo 1 kunye ne-2, ngokwahlukeneyo.
Umzobo 1: I-Off-Axis I-Axing Irhasi yokukhusela igesi
Umzobo 2: Igesi yokukhusela igesi
Ukukhetha phakathi kweendlela ezimbini zokuvutha kuxhomekeke kuqwalaselo ezahlukeneyo. Ngokubanzi, kuyacetyiswa ukuba isebenzise indlela yokuvutha ecaleni kwe-Axis ye-Axis ye-Axis yokukhusela igesi.

Imigaqo yokukhetha indlela yokwazisa igesi yokukhusela igesi
Okokuqala, kubalulekile ukucacisa ukuba igama elithi "oxidation" le-wels yimbonakalo ye-colloquial. Kwithiyori, kubhekiselelwe ekuthandeni komgangatho we-weld ngenxa yokuphendula kweekhemikhali phakathi kwentsimbi ye-weld kunye nezinto eziyingozi emoyeni, njengeoksijini, i-nitrogen, kunye ne-hydrogen.
Ukuthintela i-oxidation ye-WAND kubandakanya ukunciphisa okanye ukuthintela unxibelelwano phakathi kwezi zinto ziyingozi kunye ne-Wigh yeTest ye-Wild ye-Weld. Lo mhlaba uphambili uquka kungekuphela nje i-chiel yechibi le-Woold ye-Woold kuphela kodwa nexesha lonke le-Wold inyibilikisiwe kude kube le chibi lincipha ngezantsi komda othile.
Umzekelo, kwi-welding ye-titanium ye-alloys, xa iqondo lobushushu lingaphezulu kwama-300 ° C ukuba ne-hydrogen yenzeke; ngaphezulu kwe-450 ° C, ukuphuma kweoksijini yeoksijini kwenzeka; Kwaye ngaphezulu kwe-600 ° C, ukufunxa kwe-nitrogen ngokukhawuleza kwenzeka. Ke ngoko, ukhuseleko olufanelekileyo luyafuneka kwi-Alotium Alo Allound Allold ngexesha lesigaba xa ikhula kwaye iqondo lobushushu layo lincipha ngezantsi kwe-300 ° C ukubathintela i-oxidation. Ngokusekwe kule nkcazo ingentla, kucacile ukuba ukhuselo lwegesi iqhuma kufuneka bakhuseleke kuphela kwiphuli ye-WED ye-WODT. Yiyo loo nto, indlela yokuvuthelwa ecaleni kwe-Axis eboniswe kumzobo 1 ithathelwa ingqalelo kuba inika indawo ebanzi yokhuseleko xa ithelekiswa nendlela yokukhusela i-coaial eboniswe kumgangatho we-weld. Nangona kunjalo, kwiimveliso ezithile ezithile, ukhetho lwendlela kufuneka lwenziwe ngokusekwe kubume bemveliso kunye nolungiselelo oludibeneyo.

Ukhetho olukhethekileyo lwendlela yokwazisa igesi yokukhusela igesi
I-1. I-Wight-Line
Ukuba imilo yemveliso yemveliso ithe tye, njengoko kubonisiwe kumzobo 3, kwaye ulungiselelo oludibeneyo lubandakanya amalungu e-Butt, i-Willlet Woods, indlela ekhethiweyo yolu hlobo lwemveliso iboniswe Umzobo 1.
Umzobo 3: Umgca othe tye
I-2. I-Cacet Gemetry efakiweyo
Njengoko kubonisiwe kumzobo 4, i-WOld kolu hlobo lwemveliso inemilo yedatha evaliweyo, efana nesetyhula, i-polygonal, okanye imozulu yemigca. Ukuqwalaselwa ngokudibeneyo kunokubandakanya ukudibanisa i-butt, amalungu e-lex, okanye i-stack yeds. Ngolu hlobo lwemveliso, indlela ekhethiweyo kukusebenzisa irhasi yokukhusela i-coaxial eboniswe kumzobo 2.
Umzobo 4: I-CELREAR efakwe i-geometry ye-geometry
Ukukhethwa kwegesi yokukhusela igesi ye-Plametri efakwe ngokuthe ngqo i-Woometry ye-Ilds ichaphazela ngokuthe ngqo umgangatho, ukusebenza kakuhle, kunye neendleko zemveliso ye-welding. Nangona kunjalo, ngenxa yokwahluka kwezixhobo ze-welding, ukhetho lwerhasi ye-welding lunzima kwiinkqubo zokwenyani. Ifuna ukuqwalaselwa ngokuqinileyo kwezixhobo ze-welding, iindlela ze-welding, izikhundla ze-welding, kunye nesiphumo seWoldlings esinqwenelekayo. Ukukhethwa kweyona gesi ifanelekileyo ye-welding kunokugqitywa ngeemvavanyo ze-welding ukufezekisa iziphumo zeWeldling.
