Mai ʻae i nā nīnau
E hoʻomau mau iā ʻoe
Paʻa ʻole ʻo Arc
ʻO ka hoʻoheheʻe ʻana
ʻO ka pipiʻi nui
Hana maikaʻi ke kaʻina hana kuʻi
ʻOi aku ka maikaʻi o ka intergranular corrosion ma muli o ka hoʻohui ʻana o Nb
Maikaʻi ka ripple
He kūpono no ka welding kiʻekiʻe wela
nā ʻāpana kūʻokoʻa e koi ana i ka mālama wela kūpaʻa
Kuʻi kalapona kiʻekiʻe 18% Cr-8% Ni-Nb kila kila a me kalapona kiʻekiʻe 18% Cr-8% Ni-Ti kila kila, etc.
ʻO ka slagging maʻalahi
