Indlela yokuVuthuza yeGesi eKhuselayo

Okwangoku, kukho iindlela ezimbini eziphambili zokuvuthela igesi yokukhusela: enye i-paraxial side-blowing gas ekhuselayo, njengoko kuboniswe kuMzobo 1; Enye igesi yokukhusela i-coaxial.Ukhetho oluthile lweendlela ezimbini zokuvuthela luqwalaselwa kwiinkalo ezininzi.Ngokubanzi, kuyacetyiswa ukuba kusetyenziswe ukuvuthela ecaleni ukukhusela igesi

igesi ekhuselayo evuthela iparaxial

igesi ekhuselayo evuthela i-coaxial

Okokuqala, kufuneka kucace ukuba into ebizwa ngokuba yi-weld "i-oxidized" kuphela igama eliqhelekileyo.Ngokwethiyori, ibhekiselele kwindlela yokusabela kweekhemikhali phakathi kwe-weld kunye nezithako eziyingozi emoyeni, ezikhokelela ekuwohlokeni komgangatho we-weld.Kuqhelekile ukuba i-weld metal isabele ngeoksijini, initrogen kunye nehydrogen emoyeni kwiqondo lobushushu elithile.

Ukuthintela i-weld ekubeni "i-oxidized" kukunciphisa okanye ukuphepha ukudibanisa kwezithako ezinobungozi kunye nentsimbi ye-weld kwindawo yokushisa ephezulu.Lo mbuso ubushushu eliphezulu hayi kuphela metal etyhidiweyo pool, kodwa lonke ixesha inkqubo ukususela kwixesha xa intsimbi weld inyibilika ekuqinisweni pool metal kunye lobushushu yayo kuncitshiswe ubushushu ethile ngezantsi.

Umzekelo, i-titanium alloy welding, xa ubushushu bungaphezulu kwe-300 ℃ inokufunxa i-hydrogen ngokukhawuleza, ngaphezu kwe-450 ℃ inokufunxa ioksijini ngokukhawuleza, ngaphezu kwe-600 ℃ inokufunxa ngokukhawuleza i-nitrogen, ngoko ke i-titanium alloy welding seam emva kokuqina kunye nokunciphisa ubushushu ukuya kuma-300 ℃ ngezantsi kwesi sigaba kufuneka sibe nefuthe lokukhusela elisebenzayo, ngaphandle koko liya kuba "i-oxidized".

Ukusuka kule nkcazelo ingasentla akukho nzima ukuqonda, ukukhuselwa kwerhasi evuthelayo akufuneki kuphela ngexesha elifanelekileyo ukukhusela i-weld pool etyhidiweyo, kwakhona kufuneka idityaniswe kwindawo enomkhenkce yokukhusela, ngoko ngokubanzi yamkele i-paraxial eboniswe kumfanekiso we-1 kwicala lokukhusela. igesi, kuba le ndlela inxulumene neendlela zokukhusela uluhlu lokhuseleko lwe-coaxial yokhuseleko lwe-2 lubanzi ngakumbi, Ingakumbi kwindawo ye-weld eqinisiweyo inokhuseleko olungcono.

Icala leParaxial elivuthela kwizicelo zobunjineli, ayizizo zonke iimveliso ezinokusebenzisa indlela ye-shaft side evuthela igesi yokukhusela, kwezinye iimveliso ezithile, inokusebenzisa kuphela igesi yokukhusela i-coaxial, iimfuno ezithile ezivela kwisakhiwo semveliso kunye nefom edibeneyo yokukhetha okujoliswe kuyo.

1. Iiwelds ezithe ngqo

Njengoko kubonisiwe kuMzobo 3, imilo ye-weld yemveliso ilungile, kwaye ifom edibeneyo ingaba yi-butt joint, i-lap joint, i-joint yekona engafanelekanga okanye i-welding joint joint.Kolu hlobo lwemveliso, kungcono ukwamkela icala le-sideshaft elivuthela indlela yegesi yokukhusela njengoko kubonisiwe kuMfanekiso 1.

2. Umzobo ovaliweyo weld

Njengoko kubonisiwe kwi-Figure 4, imilo ye-weld yemveliso iyimilo ye-plane circumferential, i-plane shape multilateral shape, i-plane multi-segment line shape kunye nezinye iimilo ezivaliweyo.Ifom edibeneyo ingaba yi-butt joint, i-lap joint, i-welding edibeneyo kunye nokunye.Ngolu hlobo lwemveliso, kungcono ukwamkela imowudi yegesi ekhuselayo ye-coaxial eboniswe kuMfanekiso 2.

Ukukhethwa kwegesi ekhuselayo kuchaphazela ngokuthe ngqo umgangatho we-welding, ukusebenza kakuhle kunye neendleko zemveliso, kodwa ngenxa yokwahluka kwezinto ze-welding, kwinkqubo yokudibanisa i-welding, ukukhethwa kwegesi ye-welding kunzima kakhulu, kufuneka kuqwalaselwe ngokubanzi izinto zokuwelda, indlela yokuwelda. , indawo yokuwelda, kunye neemfuno zempembelelo ye-welding, ngokusebenzisa iimvavanyo ze-welding ukukhetha ezifanelekileyo ngakumbi kwi-welding igesi, i-welding ukufezekisa iziphumo ezingcono.
