Kuqhelekile ukuba imibhobho yentsimbi yekhabhoni edityanisiweyo ibe namaqamza omoya kwiweld, ngakumbi i-carbon-diameter enkulu engenamthungo yentsimbi yombhobho we-weld pores ayichaphazeli nje ukuqina kwe weld yepayipi kwaye ibangele ukuvuza kwemibhobho, kodwa kwakhona ibe yindawo yokurhweba. kunciphisa kakhulu amandla kunye nokuqina kwe-weld. . Izinto ezibangela i-porosity kwi-weld zezi: ukufuma, ukungcola, isikali se-oxide kunye nokufakwa kwentsimbi kwi-flux, amacandelo e-welding kunye nobukhulu bokugquma, umgangatho ophezulu wepleyiti yentsimbi kunye nokunyangwa kwepleyiti yecala yentsimbi, inkqubo yokuwelda kunye nombhobho wentsimbi. inkqubo yokwenza, njl. Ukuqulunqwa kwe-Flux. Xa i-welding iqulethe ixabiso elifanelekileyo le-CaF2 kunye ne-SiO2, iya kusabela kwaye ithathe inani elikhulu le-H2, kwaye ivelise i-HF ngokuzinza okuphezulu kunye ne-insolble in metal liquid, enokuthintela ukubunjwa kwe-hydrogen pores.

Amaqamza avela kumbindi we weld bead. Esona sizathu sesokuba i-hydrogen isafihlwe ngaphakathi kwintsimbi ye-weld ngendlela yamaqamza. Ngoko ke, umlinganiselo wokuphelisa esi siphene kukuqala ukususa i-rust, ioli, ukufuma kunye nomswakama kwi-welding wire kunye ne-weld. kunye nezinye izinto, ezilandelwa yi-flux kufuneka zomiswe kakuhle ukususa ukufuma. Ukongeza, kukwasebenza kakuhle ukunyusa okwangoku, ukunciphisa isantya se-welding, kunye nokucothisa isantya sokuqina kwesinyithi esityhidiweyo.

Ubuninzi bokuqokelelana kwe-flux ngokuqhelekileyo yi-25-45mm. Ubuninzi be-particle ubukhulu be-flux kunye nobuninzi obuncinci buthathwa njengexabiso eliphezulu, ngaphandle koko ixabiso elincinci lisetyenzisiweyo; isantya esiphezulu sangoku kunye nesantya esisezantsi se-welding sisetyenziselwa ubuninzi bokuqokelela, kwaye ixabiso elincinci lisetyenziswe ngokuchaseneyo. Xa ukufuma kuphezulu, i-flux efunyenweyo kufuneka yomiswe ngaphambi kokusetyenziswa. Ukuqhekeka kwesulfure (iintanda ezibangelwa yisulfure). Ukuqhekeka okubangelwa yi-sulfide kwibhendi yokwahlulwa kwesulfure ukungena kwintsimbi ye-weld xa iipleyiti ze-welding ezineebhanti eziqinileyo zokwahlula isulfure (ingakumbi intsimbi ethambileyo ebilayo). Isizathu salokhu kubukho be-hydrogen kwi-iron sulfide kunye nentsimbi enendawo ephantsi yokunyibilika kwindawo yokwahlula isulfure. Ngoko ke, ukwenzela ukuthintela oku kungenzeki, kukwasebenza ngokufanelekileyo ukusebenzisa isinyithi esibuleweyo okanye intsimbi ebuleweyo kunye neebhanti zokucalula ezinesulfure ezincinci.
