Yini okufanele ngiyenze uma kunezimbobo zokushisela ekucubunguleni isakhiwo sensimbi?

Ekucutshungulweni kwezakhiwo zensimbi, ikakhulukazi ohlelweni lwe-welding, kunemininingwane eminingi okufanele iphawulwe futhi ivinjwe kusengaphambili, njengokuthi ungabhekana kanjani nama-pores welding, okukholelwa ukuthi kuyinkinga enameva ehlukumeza abakhiqizi abaningi besakhiwo sensimbi.Thola nawe ngokulandelayo.

Okokuqala, ake siqonde imithethonqubo efanele mayelana nama-pores welding ekucubungulweni kwesakhiwo sensimbi: ama-welds ebanga lokuqala nelesibili awavunyelwe ukuba nokukhubazeka kwe-porosity;amashisela ebanga lesithathu avunyelwe ukuthi abe namadayamitha angu-<0.1t kanye no-≤3mm ngobude obungama-50mm bokushisela.Kunezimbobo zomoya ezi-2;isikhala sembobo kufanele sibe ≥ izikhathi eziyisi-6 ububanzi bembobo.

Okulandelayo, sizohlaziya izizathu eziqondile zokwakheka kwalezi zimbotshana zokushisela ekucubungulweni kwezakhiwo zensimbi:

1. Kukhona amabala amafutha, amabala okugqwala, amabala amanzi kanye nokungcola (ikakhulukazi izimpawu zokupenda) emseleni kanye nobubanzi obuhlobene obuzungezile, okungenye yezizathu zokubonakala kwama-pores ku-weld;

2. Isendlalelo se-copper plating yocingo lwe-welding luhlutshiwe kancane, ukuze ingxenye igqwalile, futhi i-welding seam izophinde ikhiqize ama-pores;

3. I-post-heating (i-deoxidation) ye-workpiece ewugqinsi ayenziwa ngesikhathi ngemuva kokushiswa, noma izinga lokushisa elingemuva kokushisa akwanele, noma isikhathi sokubamba akwanele, okungase kubangele ama-pores asele ku-weld;

4. Kukhona ubudlelwano obuqondile phakathi kwama-pores angaphezulu kanye nokushisa kokubhaka kwe-welding material, isivinini sokushisa sishesha kakhulu, futhi isikhathi sokubamba asanele.

Ngemuva kokuqonda izimbangela ze-welding porosity ekucubunguleni isakhiwo sensimbi, kubaluleke kakhulu ukufunda izinyathelo zayo zokuvimbela:

1. Izimbotshana ezingaphezulu ezinenombolo encane nobubanzi obuncane zingagaywa ngesondo lokugaya elingu-angular, kuze kube yilapho le ngxenye ingashintsha kahle ngayo yonke i-weld futhi ishintshe ngokushelelayo kusisekelo sensimbi;

2. I-workpiece ewugqinsi kufanele ishiswe ngaphambi kokuba i-welding futhi ifinyelele izinga lokushisa elidingekayo ngokucaciswa.Ama-workpieces aminyene kufanele alawule ngokuqinile izinga lokushisa phakathi kwamathrekhi;

3. Izinto zokushisela kufanele zibhakwe futhi zigcinwe zifudumele ngokuvumelana nemithethonqubo, futhi akufanele zibe semkhathini isikhathi esingaphezu kwamahora angu-4 ngemva kokusetshenziswa;

4. Naka indawo yokushisela ngesikhathi sokushisela.Ukushisela kufanele kumiswe lapho umswakama ohlobene ungaphezu kuka-90%;i-arc welding manual yenziwa lapho isivinini somoya sidlula i-8m/s, futhi ukushisela okuvikelwe kwegesi kwenziwa lapho isivinini somoya sidlula i-2m/s.Lapho izinga lokushisa lingaphansi kuka-0 ° C, i-workpiece kufanele ifudunyezwe ibe ngu-20 ° C, futhi ucezu lomsebenzi okufanele lushiswe kuqala kufanele lushiswe ngo-20 ° C ngalesi sikhathi.

5. Naka imingcele yenqubo ye-welding futhi uthuthukise amakhono ama-welders.Umgqomo wokushisela okuvikelwe ngegesi kufanele uphephethwe ngomoya ocindezelwe njalo ukuze kukhishwe ukungcola.

Imininingwane inquma impumelelo noma ukwehluleka, futhi kunamathuba amaningi ezinkinga ekushiseleni, okuphawuleka kakhulu ekucubunguleni isakhiwo sensimbi.
