Tataiso ea Motheo ea ARC Welding Electrodes

LIEKETSENG

Ho na le mefuta e mengata e fapaneng ea li-electrode tse sebelisoang ts'ebetsong ea tšepe e sirelelitsoeng ea arc, (SMAW).Sepheo sa tataiso ena ke ho thusa ka ho khetholla le ho khetha li-electrode tsena.

LEHLOHONOLO ELECTRODE

Li-electrode tsa li-arc welding li khetholloa ho sebelisoa mokhoa oa ho bala oa AWS, (American Welding Society) 'me o entsoe ka boholo ho tloha 1/16 ho ea ho 5/16.Mohlala e ka ba molamu oa ho cheselletsa o tsejoang e le electrode ea 1/8" E6011.

Electrode ke 1/8" bophara.

"E" e emetse arc welding electrode.

E latelang e tla ba nomoro ea 4 kapa 5 e hatisitsoeng holim'a electrode.Linomoro tse peli tsa pele tsa nomoro ea 4 le linomoro tsa pele tse 3 tsa nomoro ea 5 li bonts'a matla a fokolang (ka liponto tse likete ka lisenthimithara tse lisekoere) ea weld eo molamu o tla e hlahisa, khatello ea maikutlo e imolohile.Mehlala e ka ba ka tsela e latelang:

E60xx e ne e tla ba le matla a matla a 60,000 psi E110XX e ne e tla ba 110,000 psi.

Nomoro e latelang ho isa ho ea ho qetela e bontša boemo boo eleketrode e ka sebelisoang ho eona.

1.EXX1X ke ea ho sebelisoa maemong ohle

2.EXX2X ke ea ho sebelisoa maemong a bataletseng le a rapameng

3.EXX3X ke ea ho tjheseletsa sephara

Linomoro tse peli tsa ho qetela hammoho, li bonts'a mofuta oa ho roala holim'a eleketrode le hona joale oa welding eleketrode e ka sebelisoang le eona.Tse kang DC straight, (DC -) DC reverse (DC+) kapa AC

Ha ke na ho hlalosa mofuta oa liaparo tsa li-electrode tse fapaneng, empa ke tla fana ka mehlala ea mofuta oa hona joale oo e mong le e mong a tla sebetsa le oona.

LIEKETSENG LEKHOANE

SMAW e etsoa ho sebelisoa AC kapa DCcurrent.Kaha DC hajoale e phalla ka lehlakoreng le le leng, DC ea hona joale e ka ba DC e otlolohileng, (electrode negative) kapa DC reversed (electrode positive).Ha DC e khutlisetsoa morao, (DC+ KAPA DCRP) ho kenella ha weld ho tla teba.DC straight (DC- KAPA DCSP) weld e tla ba le lebelo la ho qhibiliha le depositi kapele.Weld e tla ba le ho kenella ha mahareng.

Ac e fetoha polarity makhetlo a 120 ka motsotsoana ka boeona 'me e ke ke ea fetoloa joalo ka ha DC ea hajoale.

BOKOLO BA ELECTRODE LE AMPS SEBELISA

Lintlha tse latelang li tla sebetsa e le tataiso ea motheo ea mefuta ea amp e ka sebelisoang bakeng sa li-electrode tsa boholo bo fapaneng.Hlokomela hore litekanyetso tsena li ka fapana pakeng tsa lihlahisoa tse fapaneng tsa li-electrode bakeng sa molamu oa boholo bo tšoanang.Hape mofuta oa ho roala holim'a electrode o ka ama mefuta e mengata ea amperage.Ha ho khoneha, hlahloba lintlha tsa moetsi oa eleketrode eo u tla e sebelisa bakeng sa litlhophiso tsa bona tse khothaletsoang.
