IKE NUI WELDING
Mai ʻae i nā nīnau
E hoʻomau mau iā ʻoe
Paʻa ʻole ʻo Arc
ʻO ka hoʻoheheʻe ʻana
ʻO ka pipiʻi nui
He kūpono no ke kila kila a me ke kila kalapona,
ʻoihana petrochemical reactor i loko o ka paia i hoʻoneʻe ʻia i ka metala hoʻololi;
A i ʻole i hoʻohana ʻia i ka ʻino ʻino o ka martensite, ferritic stainless steel welding.
Maikaʻi ka ripple
ʻAno ʻakika lima kila kila, jet arc,
ʻO ka mea nui he haʻahaʻa C-22% Cr-12% Ni, maikaʻi ke kū'ēʻana
ʻO ka hana kuʻi ʻana maikaʻi, kūpaʻa arc, hoʻohua maikaʻi, ripple palupalu, paʻi liʻiliʻi, wehe ʻia ka slag maʻalahi;
Loaʻa ka pale ahi maikaʻi, kūpaʻa porosity maikaʻi,
paʻa mechanical waiwai o ka metala hehee, a kiʻekiʻe X-Ray pass rate.
ʻO ka slagging maʻalahi
