I-AWS A5.1 E7015 i-low-hydrogen sodium coated carbon steel electrode.
I-E7015 ye-welding electrode kufuneka iqhutywe kwi-DCEP.Inokusebenzisa kakuhle i-welding eyenza ukuba yenze i-welding-position yonke, ine-arc ezinzileyo, ukususa i-slag kulula kwaye ine-spatter ephantsi.Intsimbi egciniweyo inokusebenza kakuhle koomatshini kunye nokumelana nokuqhekeka, okubonelela ngokuqina okuhle kobushushu obuphantsi.
Isicelo
I-AWS A5.1 E7015 isetyenziswa kwi-welding medium-carbon steel kunye nezakhiwo ezine-alloy ephantsi ezifana ne-16Mn, 09Mn2Si, 09Mn2V kunye neentsimbi ezisetyenziselwa ukwakha iinqanawa ezifana ne-A, B, D, E. Ikwasetyenziswa kwiipleyiti zentsimbi kunye izakhiwo zentsimbi zekhabhoni ekunzima ukuzidibanisa.

Amanqaku:
1. I-electrode kufuneka ifudunyezwe kwiqondo lokushisa lama-350 ° C ngeyure eli-1.Preheat intonga nanini na xa isetyenziswa.
2. Ukungcola okufana nomhlwa, amabala e-oyile kunye nokufuma kufuneka kususwe kwindawo yokusebenza.
3. I-arc emfutshane iyadingeka ukwenza i-welding.Indlela ye weld emxinwa iyakhethwa.
