IZICELO:
Ifanele ukushisela insimbi empunga enamandla aphezulu kanye nensimbi ehlanganisiwe enezimbotshana, njengesilinda, ibhulokhi yenjini, ibhokisi legiya, njll.
UKUHLELA:
I-AWS A5.15 / ASME SFA5.15 ENiFe-CI
I-JIS Z3252 DFCNiFe
IZIMALI:
I-AWS ENiFe-CI (Z408) iyi-electrode yensimbi ehlanganisiwe ene-nickel iron alloy core kanye nokunciphisa okukhulu kwe-graphite coating. Ingasetshenziswa ku-AC kanye ne-DC dual purpose, ine-arc ezinzile, futhi kulula ukuyisebenzisa. I-electrode inezici zamandla aphezulu, i-plasticity enhle, i-low linear expansion coefficient njalo njalo. Ukumelana nokuqhekeka kwensimbi ehlanganisiwe empunga kufana nalokho kwe-Z308, kanti ukumelana nokuqhekeka kwensimbi ehlanganisiwe empunga kungaphezu kwe-ENi-CI (Z308). Ngensimbi ehlanganisiwe ene-phosphorus ephezulu (0.2%P), nayo inemiphumela emihle futhi ukusebenza kwayo kokusika kuphansi kune-Z308 kanye ne-Z508 kancane. I-Z408 isetshenziswa ekuhlanganiseni insimbi ehlanganisiwe empunga kanye nensimbi ehlanganisiwe empunga endaweni.
QAPHELA:
Ngaphambi kokushisela, ama-electrode kudingeka abhakwe ihora eli-1 ngokushisa okungu-150±10℃ ngaphambi kokusebenzisa.
Uma ushisela, kufanelekile ukuthatha i-weld encane futhi ubude be-weld ngayinye akufanele budlule u-50mm. Shaya indawo yokushisela kancane ngesando ngokushesha ngemva kokushisela ukuze ususe ukucindezeleka futhi uvimbele imifantu.
Kunconywa ukufaka ukushisa okuphansi.
UKUBUMBEKA KWAMAKHEMIKI YENSIMBI EDIPHIWE (INGXENYE ENKULU): %

ISITHEMBISO SOKUSHINTSHA NGOKUSHINTSHA:(AC,DC+)
| Ububanzi be-electrode (mm) | 3.2 | 4.0 | 5.0 |
| Ubude (mm) | 350 | 350 | 350 |
| Ukushisela kwamanje (A) | 90-110 | 120-150 | 160-190 |
Izici Zokusetshenziswa:
I-arc eqinile kakhulu.
Ukususwa okuhle kakhulu kwe-slag.
Ukungena akujulile.
Ukumelana okuhle nokushisa nokugqwala.
Ukumelana okuhle kakhulu nokuqhekeka.
