I-Stainless Steel Electrodes CB-A102

Isaziso sokusebenzisa i-electrode yensimbi engagqwali

1. Insimbi engagqwali ye-chromium inokumelana nokugqwala okuthile (i-oxidizing acid, i-organic acid, i-cavitation), ukumelana nokushisa nokumelana nokugqoka.Imvamisa isetshenziswa ezitshalweni zamandla, amakhemikhali, i-petroleum nezinye izinto zokwakha.I-Chromium insimbi engagqwali i-weldability empofu, kufanele inake inqubo yokushisela, izimo zokwelashwa kokushisa nokukhethwa kwe-electrode efanele.

2. I-CR-13 insimbi engagqwali inokuqina okuphezulu ngemuva kokushisela futhi kulula ukuyikhiqiza i-crack.Uma uhlobo olufanayo lwe-electrode yensimbi engagqwali ye-chromium (G202, G207) lusetshenziselwa ukushisela, kufanele lushiswe kuqala ngaphezu kuka-300 ° C futhi lupholile cishe ngo-700 ° C ngemva kokushisela.Uma i-welding ingakwazi ukwenziwa ukwelashwa kokushisa kwe-post-weld, khona-ke ukukhetha kwe-chromium-nickel insimbi engagqwali electrode (A107, A207) .

3. I-Chromium 17 insimbi engagqwali, ukuze kuthuthukiswe ukumelana nokugqwala nokushisela futhi kwandiswe inani elifanele lezinto zokuzinza ezifana ne-Ti, Nb, Mo, njll., ukushisela kungcono kune-chromium 13 insimbi engagqwali.Uma kusetshenziswa uhlobo olufanayo lwe-electrode yensimbi engagqwali ye-chromium (G302, G307) kufanele ishiswe kuqala ngaphezu kuka-200 ° C futhi ifudumale ibe ngu-800 ° C ngemva kokushisela.Uma i-welding ingakwazi ukuphathwa ngokushisa, khona-ke ukukhetha kwe-electrode yensimbi engenasici ye-chromium-nickel (A107, A207).I-electrode yensimbi engenasici ye-CR-NI inokumelana nokugqwala okuhle nokumelana ne-oxidation, isetshenziswa kabanzi embonini yamakhemikhali, umanyolo, uphethiloli, ukukhiqizwa kwemishini yezokwelapha.

I-4. 0 nangaphansi ingasetshenziselwa ukushisela yonke indawo.

I-5. 0 nangaphezulu ye-welding flat kanye ne-fillet welding.

6. I-Chromium-nickel yensimbi engagqwali inohlobo lwe-titanium-calcium kanye nohlobo lwe-hydrogen oluphansi.Uhlobo lwe-Calcium titanate lungasetshenziswa ku-AC naku-DC, kodwa ukungena kokushisela kwe-AC okungajulile, kuyilapho kulula ukubomvu, ukuze kusetshenziswe ugesi we-DC.Ububanzi

7. I-electrode kufanele igcinwe yomile, uhlobo lwe-titanium-calcium kufanele lomiswe ku-150 ° C ihora eli-1, futhi uhlobo oluphansi lwe-hydrogen kufanele lomiswe ku-200 ° C kuya ku-250 ° C ihora elingu-1 (akukho ukomiswa okuphindaphindiwe, ngaphandle kwalokho. i-coating ilula ukuqhekeka nokukhipha) , vimbela amafutha okunamathela e-electrode kanye nokunye ukungcola, ukuze ungakhulisi okuqukethwe kwekhabhoni ye-weld futhi uthinte ikhwalithi ye-welding.

8. Ukuze uvimbele ukugqwala phakathi kwamehlo okubangelwa ukushisa, i-welding current akufanele ibe nkulu kakhulu, ingaphansi kwe-carbon steel electrode cishe ngo-20%, i-ARC akufanele ibe yinde kakhulu, ukupholisa okusheshayo phakathi kwezingqimba, ukuze ubuhlalu obuncane bufanele. .
