Kuʻihao kila kalaponaʻElekoda
J421
GB/T E4313
ʻAWS A5.1 E6013
Wehewehe: He electrode kila kalapona ʻo J421 me ka uhi titanium a me ka potassium kiʻekiʻe. Hiki ke hoʻohana ʻia no ka hoʻopili ʻana i nā kūlana āpau me AC a me DC. Loaʻa iā ia ka hana hoʻopili kiʻekiʻe a maʻalahi hoʻi e hoʻomaka hou i ke arc.
Noi: Kūpono no ka hoʻopili ʻana i nā hale kila kalapona haʻahaʻa, kūpono loa no ka hoʻopili ʻana i nā ʻāpana liʻiliʻi o nā papa lahilahi a me nā hoʻopili pōkole a me ka hoʻopili ʻana i ka uhi e pono ai nā ʻili laumania.
