Ingxube yethusi ne-CopperUkushiselaI-Electrode
T107
GB/T ECu
I-AWS A5.6 ECu
Incazelo: I-T107 iyi-electrode yethusi ehlanzekile enethusi elihlanzekile njengomnyombo futhi embozwe nge-low-hydrogen uhlobo lwe-sodium.Sebenzisa i-DCEP (i-electrode yamanje eqondile eqondile).Izakhiwo ezinhle zemishini, ukumelana nokugqwala okuhle emkhathini nasemanzini olwandle, akufanelekile ukushisela ithusi eline-oxygen ne-electrolytic.
Isicelo: Isetshenziselwa kakhulu ukushisela izingxenye zethusi ezifana nezinsimbi zethusi eziqhutshwayo, izishintshisi zokushisa zethusi, namapayipi amanzi olwandle emikhumbi.Ingase futhi isetshenziselwe ukushisela izingxenye ze-carbon steel ukumelana nokugqwala kwamanzi olwandle.
Ukwakheka kwamakhemikhali ensimbi ye-weld(%):
| Cu | Si | Mn | P | Pb | Fe+Al+Ni+Zn |
| 95.0 | ≤0.5 | ≤3.0 | ≤0.30 | ≤0.02 | ≤0.50 |
Izici zemishini ye-weld metal:
| Into yokuhlola | Amandla aqinile Mpa | Ukwelula % |
| Kuqinisekisiwe | ≥170 | ≥20 |
Okwamanje okunconyiwe:
| Ububanzi benduku (mm) | 3.2 | 4.0 | 5.0 |
| UkushiselaOkwamanje (A) | 120 ~ 140 | 150 ~ 170 | 180 ~ 200 |
Isaziso:
1. I-electrode kufanele ibhakwe cishe ku-200 ° C ihora elingu-1 ngaphambi kokushisela, futhi umswakama, amafutha, ama-oxides nokunye ukungcola ebusweni be-weldment kufanele kususwe.
2. Ngenxa ye-thermal conductivity yethusi, kanye nezinga lokushisa langaphambi kokhuni oluzoshiselwa ngokuvamile liphakeme ngokuqhathaniswa, ngokuvamile ngaphezu kuka-500 °C.Ubukhulu be-welding current kufanele buhambisane nokushisa kwangaphambi kokushisa kwensimbi eyisisekelo;Zama ukushisela i-arc emfushane eqondile.Ingasetshenziselwa ukuphindaphinda ukunyakaza komugqa ukuthuthukisa ukwakheka kokushisela.
3. Ukuze uthole ama-welds amade, zama ukusebenzisa indlela ye-welding ye-back step, futhi isivinini sokushisela kufanele sibe ngokushesha ngangokunokwenzeka.
Lapho i-welding enezingqimba eziningi, i-slag phakathi kwezingqimba kufanele isuswe ngokuphelele;ngemuva kokushisela, gaya i-weld ngesando sekhanda eliyisicaba ukuze unciphise ukucindezeleka,
Thuthukisa ikhwalithi yokushisela.
