ʻO ke Alakaʻi Loa i nā Koʻokoʻo Kuʻi kila Haʻahaʻa

I ke kuʻi ʻana i nā kila haʻahaʻa haʻahaʻa, he mea koʻikoʻi ke koho ʻana i ka electrode kūpono no ka hoʻokō ʻana i nā welds kiʻekiʻe a paʻa. ʻO ka W107 (AWS E7015-C2L) kahi electrode i kū i waho ma ka mākeke. ʻO kēiaʻeleka kila haʻahaʻa welaUa hoʻolālā ʻia me kahi uhi sodium haʻahaʻa-hydrogen, e kūpono ana no nā noi wiliwili ma nā wahi haʻahaʻa haʻahaʻa. Hiki ke mālama i ka paʻakikī hopena maikaʻi a hiki i -100°C, ʻo ka electrode W107 kahi hopena hilinaʻi no nā papahana wiliwili e pono ai ka hana maikaʻi loa i nā kūlana anuanu loa.

Ua hana kūikawā ʻia ke koʻokoʻo wiliwili W107 no ka wiliwili kila haʻahaʻa a hāʻawi i nā hopena maikaʻi loa i ka ikaika a me ke kūpaʻa. ʻO kona uhi sodium haʻahaʻa-hydrogen e hōʻoiaʻiʻo ana i ka liʻiliʻi o ka omo ʻana o ka hydrogen i ka wā o ka wiliwili ʻana, he mea nui ia e pale aku i ka nahā ʻana a hōʻoia i ka pono o ka wiliwili. ʻO kēia ka mea e koho mua ai no ka wiliwili ʻana i nā hale koʻikoʻi a me nā ʻāpana i hōʻike ʻia i nā mahana haʻahaʻa, e like me nā pahu cryogenic, nā paipu a me nā lako i hoʻohana ʻia i nā aniau anuanu.

ʻO kekahi o nā hiʻohiʻona nui o ka electrode W107 ʻo ia kona versatility i nā kūlana wili. Inā paha he vertical, horizontal, overhead a i ʻole flat welding, hiki ke hoʻohana ʻia kēia electrode ma nā kūlana āpau, e hāʻawi ana i nā mea wili me ka maʻalahi a me ka maʻalahi e hana ana ma nā papahana like ʻole. Eia kekahi, ua hoʻolālā ʻia ka electrode no ka hoʻohana ʻana me DC Positive Electrode (DCEp) e hoʻokō i ka hana wili maikaʻi a paʻa hoʻi i nā noi wili like ʻole.

Mālama ka metala i waiho ʻia o ka electrode W107 i ka paʻakikī hopena maikaʻi loa ʻoiai ma nā mahana haʻahaʻa loa, e lilo ia i koho hilinaʻi no nā noi kahi i kau ʻia ai ka weld i nā kūlana anu koʻikoʻi. ʻO kēia paʻakikī kūikawā e hōʻoiaʻiʻo ana e mālama ka weld i kona kūpaʻa kūkulu a me ka hana ʻoiai ma nā wahi sub-zero, e hāʻawi ana i ka hilinaʻi lōʻihi a me ka palekana i nā ʻāpana i welded ʻia.

I ka hōʻuluʻulu manaʻo, ʻo ke koʻokoʻo wili kila wela haʻahaʻa ʻo W107 (AWS E7015-C2L) ka hopena maikaʻi loa no nā noi wili e pono ai ka hana maikaʻi loa i nā wahi mahana haʻahaʻa. ʻO kona uhi sodium hydrogen haʻahaʻa me kona hiki ke mālama i ka paʻakikī hopena maikaʻi ma -100°C e lilo ia i koho maikaʻi loa no nā mea wili e ʻimi nei i nā hopena kiʻekiʻe a hilinaʻi hoʻi i nā kūlana anuanu loa. Me kona ʻano hana wili a me ka hoʻohālikelike ʻana me DCEP, hāʻawi ka electrode W107 i nā mea wili i ka hilinaʻi a me ka hōʻoia e pono ai lākou e hoʻoponopono i nā papahana wili kila wela haʻahaʻa me ka pololei a me ka maikaʻi loa.
