I-Welders ayifuni ukwazi iimpawu zenkqubo yokushisa i-welding

Ngexesha lenkqubo ye-welding, isinyithi esidityanisiweyo sifudumala, sinyibilika (okanye sifikelele kwi-thermoplastic state) kunye nokuqina okulandelayo kunye nokupholisa okuqhubekayo ngenxa yokufakelwa kobushushu kunye nokuhanjiswa, okubizwa ngokuba yinkqubo yokushisa i-welding.

Inkqubo yobushushu be-welding ihamba kuyo yonke inkqubo ye-welding, kwaye iba yenye yezona zinto ziphambili ezichaphazela kwaye zimisela umgangatho we-welding kunye nemveliso ye-welding ngokusebenzisa le miba ilandelayo:

1) Ubungakanani kunye nokusabalalisa ubushushu obusetyenziswa kwintsimbi ye-weldment bumisela ubume kunye nobukhulu bedama elityhidiweyo.

I-2) Iqondo le-metallurgical reaction kwi-welding pool ihambelana ngokusondeleyo nefuthe lobushushu kunye nobude bexesha le-pool ekhoyo.

3) Ukutshintsha kwe-welding ukufudumeza kunye nokupholisa iparameters kuchaphazela ukuqina kunye nesigaba sokuguqulwa kwenkqubo yesinyithi etyhidiweyo, kwaye kuchaphazela ukuguqulwa kwe-microstructure yesinyithi kwindawo echaphazelekayo ubushushu, ngoko ke ulwakhiwo kunye neepropati ze-weld kunye ne-welding echaphazelekayo ngubushushu. zone nazo ezinxulumene umsebenzi ubushushu ezinxulumene.

I-4) Ekubeni inxalenye nganye ye-welding ixhomekeke ekufudumeni okungalinganiyo kunye nokupholisa, okubangelwa imeko yoxinzelelo olungalinganiyo, okubangelwa kwiidigri ezihlukeneyo zoxinzelelo kunye noxinzelelo.

5) Ngaphantsi kwesenzo sokushisa kwe-welding, ngenxa yempembelelo edibeneyo ye-metallurgy, imiba yoxinzelelo kunye nesakhiwo setsimbi ukuba sidityaniswe, iintlobo ezahlukeneyo zokuqhekeka kunye nezinye iziphene zetsimbi zingenzeka.

6) Ubushushu begalelo le-welding kunye nokusebenza kwayo kumisela isantya sokunyibilika kwesiseko sesinyithi kunye nentonga ye-welding (i-welding wire), ngaloo ndlela ichaphazela imveliso ye-welding.

Inkqubo yobushushu be-welding inzima kakhulu kunoko iphantsi kweemeko zonyango lobushushu ngokubanzi, kwaye inezi mpawu zine zilandelayo:

a. Ugxininiso lwengingqi lwenkqubo yokushisa i-welding

I-weldment ayitshisi xa iyonke ngexesha le-welding, kodwa umthombo wobushushu utshisa kuphela indawo ekufutshane nendawo yesenzo esithe ngqo, kwaye ukufudumeza kunye nokupholisa akulingani ngokugqithisileyo.

b. Ukushukuma komthombo wobushushu we-welding

Ngethuba lenkqubo ye-welding, umthombo wokushisa uhamba ngokumalunga ne-weldment, kwaye indawo eshushu ye-weldment ihlala iguquka. Xa umthombo wokushisa we-welding usondele kwindawo ethile ye-weldment, iqondo lokushisa kwinqanaba likhuphuka ngokukhawuleza, kwaye xa umthombo wokushisa uhamba ngokuthe ngcembe, inqaku liphola kwakhona.

c. Ukudlula kwenkqubo yobushushu be-welding

Ngaphantsi kwesenzo somthombo wokushisa ogxininisiweyo, isantya sokufudumeza sikhawuleza kakhulu (kwimeko ye-arc welding, inokufikelela ngaphezu kwe-1500 ° C / s), oko kukuthi, ubungakanani obukhulu bamandla obushushu adluliselwa kubushushu. umthombo kwi-weldment ngexesha elifutshane kakhulu, kwaye ngenxa yokufudumeza Izinga lokupholisa liphezulu ngenxa yendawo kunye nokuhamba komthombo wokushisa.

d. Ukudibanisa inkqubo yokudlulisa ubushushu be-weldment

Ulwelo lwesinyithi kwi-weld pool ikwimo yentshukumo eqatha. Ngaphakathi kwidama elinyibilikisiweyo, inkqubo yokuhambisa ubushushu ilawulwa yiconvection yolwelo, ngelixa ngaphandle kwedama elityhidiweyo, ukuhanjiswa kobushushu obuqinileyo kukongamela, kwaye kukho ukuhanjiswa kobushushu obuguqukayo kunye nokuhanjiswa kobushushu bemitha. Ke ngoko, inkqubo yobushushu be-welding ibandakanya iindlela ezahlukeneyo zokuhambisa ubushushu, okuyingxaki yokuhambisa ubushushu obudibeneyo.

Iimpawu zale miba ingasentla zenza ingxaki yokuhanjiswa kobushushu be-welding ibe nzima kakhulu. Nangona kunjalo, ngenxa yokuba inefuthe elibalulekileyo kulawulo lomgangatho we-welding kunye nokuphuculwa kwemveliso, i-XINFA icebisa ukuba abasebenzi be-welding kufuneka balawule imithetho yayo esisiseko kunye nokutshintsha iindlela phantsi kweeparameters zenkqubo ezahlukeneyo.
