Nkọwa: Nke a bụ elektrọd pụrụ iche nke nwere obere hydrogen sodium kpuchiri maka ígwè aluminized. Jiri DCEP (elektrọd direct current positive), enwere ike ịgbado ya n'ọnọdụ niile yana ọrụ arc dị mkpụmkpụ. Enwere ike ịgbado J557SLA ozugbo na-ewepụghị oyi akwa aluminized n'elu oghere tupu ịgbado ya. Mana J557SLB kwesịrị iwepụ oyi akwa aluminized n'elu oghere tupu ịgbado ya.

Ngwa: A na-eji ya agbakọta ihe owuwu ígwè aluminized n'okpuru ihe na-emebi emebi nke hydrogen sulfide, sọlfọ, ammonia, ammonium bicarbonate na hydrogen nitrogen nke nwere okpomọkụ ọrụ dị n'okpuru 540°C. Dịka paịpụ boiler, ngwa nchacha mmanụ ala, ngwa fatịlaịza na paịpụ uzuoku, wdg.

 Ngwakọta kemịkalụ nke ígwè weld(%):

 Njirimara mekaniki nke igwe weld:

Ọdịnaya hydrogen nke ígwè e tinyere n'ime ya: ≤6.0mL/100g (usoro glycerin)
