Welding mathata a tloaelehileng le mekhoa ea thibelo

1. Morero oa ho annealing ka tšepe ke ofe?

Karabo: ① Fokotsa ho thatafala ha tšepe le ho ntlafatsa polasetiki, e le ho thusa ho itšeha le ho sebetsa ha serame;② Hloekisa lijo-thollo, seaparo sa tšepe se tšoanang, ntlafatsa ts'ebetso ea tšepe kapa u lokisetse phekolo ea mocheso nakong e tlang;③Felisa masala ka tšepe khatello ea ka hare ho thibela deformation le ho peperana.

2. Ho tima ke eng?Morero oa eona ke ofe?

Karabo: Mokhoa oa ho futhumatsa mocheso oa tšepe ho mocheso o itseng ka holimo ho Ac3 kapa Ac1, ho o boloka ka nako e itseng, ebe o o pholile ka lebelo le loketseng ho fumana martensite kapa bainite o bitsoa quenching.Sepheo ke ho eketsa ho thatafala, matla le ho apara ho hanyetsa ha tšepe.mosebetsi wa ho tjheseletsa

3. Melemo le melemo ea ho tjheseletsa arc ka letsoho ke efe?

Karabo: A. Melemo

 

(1) Mokhoa ona oa tenyetseha ebile oa tenyetseha;(2) Boleng bo molemo;3) Ho bonolo ho laola deformation le ho ntlafatsa khatello ea kelello ka ho fetola ts'ebetso;(4) Thepa e bonolo ebile e bonolo ho sebetsa.

B. Mathata

(1) Litlhoko tsa li-welders li phahame, 'me tsebo ea ts'ebetso le phihlelo ea li-welders li ama ka ho toba boleng ba lihlahisoa.

(2) maemo a mabe a mosebetsi;(3) tlhahiso e tlaase.

4. Melemo le melemo ea ts'ebetso ea ho tjheseletsa arc e ka tlas'a metsi ke efe?

Karabo: A. Melemo

(1) Ts'ebetso e phahameng ea tlhahiso.(2) Boleng bo botle;(3) Boloka thepa le matla a motlakase;(4) Ntlafatsa maemo a mosebetsi le ho fokotsa matla a mosebetsi

B. Mathata

(1) E loketse feela bakeng sa tjheseletsa e rapameng (e tloaelehileng) ea boemo.(2) Ho thata ho tjheseletsa litšepe tse nang le oxidizing haholo le lialloys joalo ka aluminium le titanium.(3) Thepa e rarahane haholoanyane.(4) Ha motlakase o le ka tlase ho 100A, botsitso ba arc ha bo botle, 'me ha boa lokela ho tjheseletsa lipoleiti tse tšesaane tse nang le botenya bo ka tlase ho 1mm.(5) Ka lebaka la letamo le tebileng le entsoeng ka ho qhibilihisoa, le khona ho mamella li-pores haholo.

5. Melao-motheo e akaretsang ea ho khetha groove ke efe?

Karabo:

① E ka etsa bonnete ba ho kenella ha sesebelisoa sa mosebetsi (botebo ba ho kenella ha li-arc welding hangata ke 2mm-4mm), 'me e loketse ts'ebetso ea welding.

②Sebopeho sa groove se lokela ho ba bonolo ho sebetsa.

③ Ntlafatsa tlhahiso ea licheso le ho boloka lithupa tsa welding ka hohle kamoo ho ka khonehang.

④ Fokotsa deformation ea workpiece ka mor'a welding ka hohle kamoo ho ka khonehang.

6. Sebopeho sa weld ke eng?Kamano ea eona ke efe le boleng ba weld?

Karabo: Nakong ea tjheseletsa ea fusion, karo-karolelano pakeng tsa bophara ba weld (B) le botenya bo baliloeng (H) ba chesella karolong e ka holimo ea tjheseletsa e le 'ngoe, ke hore, ф=B/H, e bitsoa. mofuta oa weld form.E nyenyane ea li-weld shape coefficient, e fokolang le e tebileng ea weld, 'me li-welds tse joalo li na le tšekamelo ea ho kenya li-pore slag le mapetsong.Ka hona, sebopeho sa weld se lokela ho boloka boleng bo itseng.

7. Lisosa tsa undercut ke life le mokhoa oa ho li thibela?

Karabo: Lisosa: haholo-holo ka lebaka la khetho e sa nepahaleng ea li-parameter tsa ts'ebetso ea welding, ho chesa haholo hona joale, nako e telele ea arc, lebelo le sa lokelang la ho tsamaisa le lithupa, joalo-joalo.

Mokhoa oa thibelo: khetha lebelo le nepahetseng la welding hona joale le lebelo la welding, arc ha e khone ho otlolloa nako e telele haholo, 'me u tsebe mokhoa o nepahetseng le sekhutlo sa ho tsamaisa mohala.

8. Ke mabaka afe le mekhoa ea thibelo ea boholo ba weld surface e sa fihlelle litlhoko?

Karabo: Lebaka ke hore groove angle ea weldment e fosahetse, lekhalo la kopano ha le lekane, lebelo la ho tjheseletsa ha lea nepahala kapa mokhoa oa lipalangoang oa hlobo o fosahetse, molamu oa welding le angle li khethiloe ka tsela e fosahetseng kapa li fetotsoe.

Mokhoa oa ho thibela Khetha sekhutlo se nepahetseng sa groove le sebaka sa kopano;ka nepo khetha paramethara tshebetso tjheseletsa, haholo-holo tjheseletsa boleng hona joale le ho amohela mokhoa o nepahetseng oa tshebetso le angle ho etsa bonnete ba hore sebopeho tjheseletsa ke junifomo.
