Nā ʻano a me ka noi
ʻO nā koʻokoʻo wiliwili AWS A5.1 E7018-1 H4, ʻo ka electrode wiliwili he electrode ʻano haʻahaʻa hydrogen haʻahaʻa hao-pauka no ka wiliwili ʻana i nā kūlana āpau o ke kila tensile kiʻekiʻe 490N/mm2. Ua hoʻolālā ʻia no nā noi pass hoʻokahi a me nā noi he nui. Loaʻa i ka huahana ka hoʻopiʻi maikaʻi a hana i kahi arc paʻa me ka hanauna spatter haʻahaʻa. Hana ia i nā metala wiliwili me nā waiwai mechanical maikaʻi loa a me ka paʻakikī hopena ma ka mahana haʻahaʻa (-45 ℃) a me ka hydrogen diffusible haʻahaʻa. ʻO kona mau hiʻohiʻona e kūpono ai ka huahana no nā kila alloy haʻahaʻa, nā kila kalapona waena, nā papa kila kaumaha, nā kila i hoʻolei ʻia, ke kila alumini pepehi ʻia o LPG a ʻoi aku hoʻi no ka wiliwili ʻana o nā kila me ka weldability maikaʻi ʻole.

Nā memo no ka hoʻohana ʻana:
1. Inā ʻaʻole i hoʻopaʻa pono ʻia ke kūlana mālama a ʻaʻole i hōʻino ʻia ka hoʻopili ʻana, paipai nui mākou e hoʻomaloʻo i nā electrodes ma 350-400℃ no 1-2 mau hola ma mua o ka hoʻohana ʻana.
2. E hana i ke ʻano hana hope e pale aku i nā lua puhi ma ka hoʻomaka ʻana o ke arc.
3. Paipai nui ʻia ka mālama ʻana i ka lōʻihi pōkole o ke aʻo ʻana e pale aku i ka hōʻiliʻili ʻana o ka makū.
