AWS A5.13 ECoCr-A e thata-thata Manual electrode weld fabrication jointing
GEH-SL6 ke electrode e holim'a cobalt ho latela maemo a AWS A5.13 ECOCRA-A.E sebelisoa haholo-holo bakeng sa ho phahamisa mocheso o phahameng le li-valve tsa khatello e phahameng, likhahla tse chesang tsa ho kuta, li-valve tsa enjene, li-blades tsa turbine, joalo-joalo. E ka sebelisoa bakeng sa AC le DC ka bobeli.Ho bohlokoa ho sebelisa khokahano ea DC reverse le khokahano e ntle ea electrode.Arc e tsitsitseng, sekoahelo se setle sa slag, sebopeho se setle.Lera le ka holimo le na le lisebelisoa tse phethahetseng tsa mochini mochesong o phahameng oa mocheso o ka tlase ho 800 ℃, 'me le na le khanyetso e ntle ea kutu, ho hanyetsa oxidation le ho hanyetsa moaparo oa intermetallic.Lera le ka holimo le ka etsoa ka mechine.
Kopo & Maemo
GEH-SL6 ke mofuta oa tjheseletsa e holimo bakeng sa valve ea enjene, lehare la turbine, mocheso o phahameng le valve ea khatello e phahameng, mochini o chesang o chesang le likarolo tse ling tsa mocheso o phahameng oa ho hanyetsa le likarolo tsa ho hanyetsa kutu.Ts'ebetsong ea welding, e le hore e ka kopanngoa ka thata le substrate, ho hlokahala hore ho kenelle ka botebo ho kena.Ka hona, ho ka sebelisoa mokhoa o mokhuts'oane oa welding oa arc.Taba ea bobeli, molemong oa ho rarolla bothata ba letamo le tebileng le lisebelisoa tse feteletseng tse qhibilihang ka har'a weld nakong ea welding e khuts'oane ea arc, sekhahla sa dilution se phahame.Ho haella ha likarolo tse sebetsang karolong ea weld ho fokotsa bothata ba ho hanyetsa ho apara.E tlameha ho sebelisa mokhoa oa ho etsa li-multiple-layers.Ka tsela ena, ha se feela likarolo tse sebetsang hantle le ho itšoarela ho hanyetsa mokokotlong oa backsurfacing ho eketsa lera ka lera.Ho feta moo, likarolo tse 'maloa tsa pele tsa holimo le tsona li bapala karolo ea lera la phetoho, ho fokotsa ho phatloha ho bakoang ke phapang ea coefficient ea ho atolosa mocheso pakeng tsa lihlopha tse peli tse haufi.Ho sa le joalo, mokhoa oa ho tsamaea o otlolohileng, mokhoa oa ho sisinyeha ha litlhapi, mokhoa oa ho sisinyeha ha herringbone kapa mokhoa o mokhuts'oane oa ho sisinyeha oa arc o lokela ho amoheloa.
Likaroloana
Ena ke titanium calcium coating cobalt base surfacing electrode, e loketseng khokahano ea reverse ea DC, tšepe e kaholimo e ntse e ka boloka khanyetso e ntle ea ho roala le ho hanyetsa kutu ho 650 ℃, ho hanyetsa ka matla le ho hanyetsa mokhathala le ho chesa.E ka sebelisoa litlhoko tsa ho pota-pota 650 ℃ mosebetsi o ntse o ka boloka ho hanyetsa ho apara hantle le ho hanyetsa ho itseng ha kutu, hammoho le tšusumetso le serame le mocheso o tsitsitseng, o ka ba le tshebetso e ntle.
