Umbhobho wentsimbi odityanisiweyoyahlulwe yaba ziindidi ezimbini ngokutsho ukuwelda kwayo imilo yomthungo-ethe tye umthungo umbhobho yentsimbi kunye spiral steel pipe.

Umbhobho wentsimbi umthungo we-porosity awuchaphazeli kuphela ukuxinana kokudityaniswa kwemibhobho, okubangela ukuvuza kombhobho, kwaye iya kuba yindawo ebangelwa kukuhlwa, inciphisa ngokuqatha ukomelela kweweld kunye nokuqina.

Imiba ye-weld porosity zezi: ukuhamba kwamanzi, ukungcola, kunye ne-oxide yentsimbi, ubukhulu bamacandelo adibeneyo kunye nokugubungela, kunye nomgangatho womphezulu we-steel sheet processing side plates, inkqubo ye-welding kunye nenkqubo yokwenza umbhobho njalo njalo.

Amanyathelo olawulo afanelekileyo ngala alandelayo:

1.Icandelo le-flux.Xa iqulethe isixa esifanelekileyo se-CaF2 kunye ne-SiO2, i-welding processing iya kuthabatha izixa ezikhulu ze-H2, kwaye ivelise i-HF enozinzo oluphezulu kwaye ayinyibiliki kwintsimbi engamanzi, ngaloo ndlela inqanda ukubunjwa kwegesi ye-hydrogen. imingxuma.

2.Ubuninzi be-Accumulation of flux ngokubanzi yi-25-45mm.Xa i-Flux inedigri yamasuntswana amakhulu kunye noxinano oluncinci, thatha ubukhulu bokuqokelelana okuphezulu, ngelixa ixabiso elincinci;yangoku ephezulu, isantya esisezantsi se-welding sithatha ubukhulu obukhulu, ngelixa ixabiso elincinci.Ngaphandle koko, xa ehlotyeni okanye kwiintsuku zokufuma okuphezulu, ukubuyiswa kwe-flux kufuneka yomiswe ngaphambi kokusetyenziswa.

3 Unyango lomphezulu wentsimbi.Ukuze ugweme ukukhupha umgangatho we-iron oxide kunye nolunye udoti oluwela kwinkqubo yokubumba, isixhobo sokucoca ibhodi kufuneka simiselwe.

4 Steel plate edge unyango.Isixhobo sokususa i-rust kunye ne-burrs kufuneka sibekwe kumda wepleyiti yentsimbi ukunciphisa amathuba okwenza i-porosity.Eyona ndawo ilungileyo yokufakela isixhobo ecacileyo ikufutshane idiskhi ukusika edge oomatshini bokusila, isakhiwo isixhobo ivili ucingo esebenzayo ngelixa umsantsa ezimbini isithuba adjustable phantsi, phezulu naphantsi imiphetho ipleyiti yoxinzelelo.

5 Iprofayili yomgca we-Welding.I-welding form factor incinci kakhulu, imilo ye-weld imxinwa kwaye inzulu, igesi kunye nokufakwa akukho lula ukuvuza kwaye kulula ukwenza iipores kunye ne-slag.Ulawulo lwe-weld factor jikelele kwi-1.3-1.5, umbhobho ongqindilili ongqindilili khetha elona xabiso liphezulu, kunye nexabiso elincinci le-thin-walled.

6 Ukunciphisa indawo yesibini yemagnethi.Ukunciphisa imiphumo yokuvuthela kwamagnetic, indawo yokudibanisa kwi-workpiece kufuneka igcine kude ne-terminal ye-welding cable ukuphepha indawo yesibini yemagnethi eyenziwe kwindawo yokusebenza.

7 Iteknoloji:Ngaba ngokufanelekileyo ukunciphisa isantya welding okanye ukwandisa yangoku, ngaloo ndlela ulibazisa izinga crystallization bath metal weld, ukwenzela ukuba kube lula ukukhulula igesi, ngelixa ukuba indawo yonikezelo ayizinzanga, umcu kufuneka uhlengahlengiswe kwangexesha ukuphelisa igesi. I-asi yangaphambili ngokucheba rhoqo okanye iBridge egciniweyo isenziwa, ibangela ukuba irhasi ibaleke nzima.
