Ukunyuka ngokuzenzekelayo: iintlobo kunye neenzuzo

Okwangoku, inani elinyukayo lezityalo libandakanya ukuguqulwa kunye nokuhlaziywa kweevenkile zabo, ukuphucula izixhobo zobuchwepheshe. Kwaye, ke, kukho ukutshintshwa ngokuqhelekileyo kwee- arc zokurhambisa iimashini zokuxhoma kunye nezixhobo ezifakela ngokuzenzekelayo. Ezi zixhobo kwakhona zivumela ukwandisa umveliso, kwaye kunika amathuba amaninzi okubuyiselwa kwamalungu ngokweendlela zorhwebo kwiimveliso zorhwebo.
Iyona ndlela isetyenziswa ngokuqhelekileyo yi-arc welding. Oku kuvumela ukutyunjwa kweengxenye, ezibhekwa njengesisombululo esisemgangathweni esisenza sibe nemveliso, kwaye siphucula umgangatho wesigxobo esiphezulu.

Ukuba ukunyuka ngokuzenzekelayo kwamalungu kuqhutyelwa emoyeni ovulekile, kodwa ngexesha elifanayo kukho ukuqhutyelwa kwe-flow to the seam formed, kuthiwa ukutshiswa kwe-arc kwenzeka kwindawo efihliweyo. Le ngxaki ichazwa ngolu hlobo lokuba uhla lwe-flux luhlobo lwe-electrode coating, kwaye ke lukhusela isayithi lokumisa kwiindawo eziyingozi zomoya. Ukongezelela, ukuchithwa kwe-flux kusetyenziswa ukukhusela ukutshatyalaliswa kwentsimbi etyhidiweyo.

Ukunyuka ngokuzenzekelayo phantsi kocwangco lwe-flux ngokuqhelekileyo kwenziwa ngetambo ye-electrode ngaphandle kokubhinqa. Le ndlela ivumela ukuphelisa inani elininzi lokungaphumeleli oluhambelana nokunyuka kwe-arc kagesi. Ngexesha elifanayo, isinyithi seendawo ezixhasiweyo ziba zihambelana kakhulu, ezibangela ukuba umgangatho kunye nokuxininisa kwesigxobo esinezantsi.

Ukuba uqwalasela ngononophelo inkqubo yokudlula ukuhambisa i-welding kwiindawo ezifudumeleyo, kuya kubonakala ukuba i-arc iyatshisa isikhewu esincinane phakathi kwecandelo le-electrode kunye nomsebenzi owenziwe. Ngokuqinisekileyo, kufuneka kuphawulwe ukuba le fowuni isondliwa kwikhoyili engabonakaliyo ngokuzenzekelayo kwaye ifakwe kwinqanaba le-weld njengoko i-welding ends. Kule miba, kwindlela yokwakha eyakhelwe kumshini wokulondoloza. Ngaloo ndlela, umkhuhlane uvela kwisitya esincinci - umgcini. Iqhezu elincinci lithe qhekeza ngaphantsi kwefuthe le- arc yombane . Nangona kunjalo, emva kokuba i-weld ikhuhliwe kwaye iqiniswe, i-flux yangaphambili ichithwa isuswa kalula. Ukungasetyenziswanga kubuya kwisigxina se-hopper kwaye sisetyenziswe kwiinkqubo zokulumala ezilandelayo.

Ukunyuka ngokuzenzekelayo kubandakanya iindlela ezininzi eziphucula iimpawu zayo.

1. Ukwandisa i-welding current. Isetyenziselwa ukwandisa ubunzulu be-welding, okubizwa ngokuba yi-depth of metal penetration. Kule meko, kubalulekile ukuba ububanzi be-weld abuguqukanga.

2. Ukwandisa i-cross cross section. Oku, ngokuchasene noko, kukhokelela ekunyuseni ububanzi kunye nokuhla kwe-weld. Ngaloo ndlela, ukuguqulwa okuphazamisayo, oko kukuthi, ukunciphisa kwicandelo eliphambano lucingo, kufaka ukunyusa okunyanisekileyo nokunciphisa ububanzi be-weld.

3. Izifundo zibonise ukuba nangona kunyuka kwenyuka kwezinga le-arc kwangaphambili, ukuphakama kwe-weld bead kwanda kakhulu, ngelixa ububanzi bokungena kunye nobubanzi bomthungo buncipha.

Ngaloo ndlela, kunokuthi kuqaphele ukuba ukunyuka ngokuzenzekelayo kuphezulu kunokuba kuphakanyiswe ukunyuka kombane.
