Weld chitoliro kuwotcherera porosity zimakhudza osati makulidwe mapaipi, chifukwa payipi kutayikira ndi dzimbiri adzakhala ananyengerera mfundo kwambiri kuchepetsa kuwotcherera mphamvu ndi kulimba.Zinthu kuwotcherera porosity ndi: ndi flux m'madzi, dothi, okusayidi ndi chitsulo filings, zosakaniza kuwotcherera ndi makulidwe chivundikirocho, pamwamba zitsulo ndi zitsulo mbali mbale processing, kuwotcherera luso ndi zitsulo akamaumba njira.

Njira zopewera:

1. Flux zosakaniza.CaF2 ndi SiO2 munali yoyenera kuchuluka kwa kuwotcherera, anachita adzakhala kuyamwa yambiri H2, kupanga mkulu bata wa HF insoluble mu madzi zitsulo, potero kupewa mapangidwe mabowo mpweya wa haidrojeni.

2. The makulidwe ambiri a flux zambiri 25-45mm, lalikulu solder tinthu kukula, chochuluka kachulukidwe ola kutenga pazipita makulidwe, pamene mtengo osachepera;mkulu panopa, otsika kuwotcherera liwiro kudzikundikira kutenga pazipita makulidwe, pamene osachepera mtengo Kuwonjezera, chilimwe kapena mpweya chinyezi, flux kuchira ayenera zouma pamaso ntchito.

3. Chitsulo chopangidwa pamwamba.Kupewa otsegula-bukhu kusalaza pa oxide sikelo ndi zinyalala mu akamaumba ndondomeko, bolodi ayenera kukhala kuyeretsa chipangizo.

4. Steel mbale m'mphepete processing.Chitsulo mbale m'mphepete ayenera kukhala dzimbiri ndi burr kuchotsa chipangizo kuchepetsa zotheka m'badwo mabowo.Kuchotsa chipangizo anaika pamalo abwino pambuyo makina mphero ndi kukameta ubweya chimbale, kapangidwe ka chipangizo ndi yogwira waya gudumu mbali ziwiri mmwamba ndi pansi udindo chosinthika kusiyana, chapamwamba ndi m'munsi clamping mbale m'mphepete.

5. Weld mbiri.Weld kupanga factor ndi yaying'ono kwambiri, yopapatiza komanso yozama yowotcherera mawonekedwe, gasi ndi kuphatikiza sikophweka kutulutsa, kosavuta kupanga pores ndi slag.General weld coefficient control mu 1.3-1.5, chitoliro chokhala ndi mipanda yokhuthala, mtengo wocheperako wokhala ndi mipanda woonda.

6. Kuchepetsa yachiwiri maginito.Kuchepetsa chikoka maginito kuwomba ayenera kupangidwa pa workpiece kuwotcherera chingwe kugwirizana malo zotheka kutali ndi kuwotcherera terminal, kupewa kuwotcherera chingwe yachiwiri maginito kwaiye mu workpiece.

7. Kupanga.Ziyenera kukhala zoyenera kuchepetsa kapena kuonjezera liwiro la kuwotcherera panopa, potero kuchedwetsa crystallization mlingo wa kuwotcherera zitsulo kusamba kuti atsogolere kuthawa kwa mpweya, pa nthawi yomweyo, ngati Mzere yobereka malo kusakhazikika, ayenera nthawi yake kusintha. Chotsani kukonzanso pafupipafupi pambuyo pa kukhazikitsidwa kwa exle yakutsogolo kapena mlatho kuti musunge kuumbidwa, zomwe zimapangitsa kuti mpweya uthawe movutikira.
