AWS: SFA 5.5 E9015-B3Nā Electrodes no nā kila kū'ē kolo
ʻO ka electrode hydrogen haʻahaʻa e waiho ana i ka 2.25Cr - 1Mo metala weld, hōʻike i ka ikaika kupaianaha o a me ke kūpaʻa kolo i nā mahana kiʻekiʻe a hiki i 575 C. Hoʻohana ʻia ia no ka wili ʻana i ke kila 2 1/4 Cr-1 Mo kūpaʻa kolo a me nā kila Cr-Mo-V kūpaʻa i ka hydrogen ma lalo o ke kaomi a me nā kila i hoʻolei ʻia o kahi ʻano like me ka metala weld. ʻO nā noi maʻamau e pili ana i ke kūkulu ʻana i ka paila mahu, ka wili ʻana i nā paipu mahu a me ka super-heater, nā mea kanu mana, ka hale hoʻomaʻemaʻe aila a me nā mea kanu kemika.

Ka mālama pono ʻana
1. E hoʻomaloʻo hou i nā electrodes ma 250-300 C no hoʻokahi hola, e like me kā mākou hana maʻamau i ʻōlelo ʻia.
2. E hoʻohana i ke aʻo pōkole a me ka lei kaula.
