Yuav Ua Li Cas Weld Titanium Tube Ntawm Lub Kub Exchanger?

Titanium tubes ntawm cov cua kub exchangers yog welded nyob rau hauv tus txheej txheem, los ntawm kev tshawb nrhiav tas li, cov kev paub hauv qab no tau sau tseg.
Raws li titanium melting fluidity zoo heev, siab dua lwm cov hlau tshwj tsis yog nyiaj, yog li nyob rau hauv tag nrho txoj hauj lwm welding, nws yog pom zoo kom lub arc pib ntawm ib teev, counterclockwise welding rau 11 teev siv high-frequency arc extinguishing. , nce qhov zaus ntawm arc extinguishing, kom tsis txhob ntws ntawm molten droplets yog ceev heev, cuam tshuam qhov zoo ntawm titanium raj weld thiab cov tsos ntawm weld shaping, kom tsis txhob sib npaug weld thinning thiab thickness. Arc extinguishing yuav tsum dhau lub arc point 4 ~ bmm, thiab arc extinguishing ntawm tus pas nrig tooj liab kom tsis txhob arc crater.

Nyob rau hauv cov ntsiab lus, nyob rau hauv lub titanium raj welding, kev xaiv ntawm loj nozzle dej-txias welding torch, siv cov ntshiab tooj liab qws cua sov-absorbing ceev yam ntxwv, kom ceev tus nqi cua txias ntawm lub weld yog ib tug proven txoj kev. Cov txheej txheem ntsuas thiab cov txheej txheem kev khiav hauj lwm siv los tiv thaiv tag nrho cov vuam zoo ntawm cov khoom siv hluav taws xob, tau txais txiaj ntsig zoo, thiab tau txais txiaj ntsig kev lag luam tseem ceeb.
