Whakaahuatanga: Ko te konutai hauwai iti e hipokina ana te hiko motuhake mo te maitai aluminized.Whakamahia te DCEP (te hiko tika o naianei), ka taea te paihere ki nga waahi katoa me te mahi pewa poto.Ka taea e J557SLA te paihere tika me te kore e tango i te paparanga aluminized i runga i te mata o te haehae i mua i te whakapiri.Engari me tango e te J557SLB te paparanga aluminized i runga i te mata haehae i mua i te whakapiri.

Taupānga: Kei te whakamahia mō te fehokotaki'anga i te hanganga maitai aluminized i raro i te reo waikura o hauwai sulfide, whanariki, haukinia, haukinia bicarbonate me te hauwai hauota ki te pāmahana mahi i raro i 540°C.Pērā i ngā paipa kōhua, taputapu para hinu, taputapu tongi me nga paipa mamaoa, aha atu.

Panui:

1. Me tunuhia te electrode mo te 1 haora i te taha o te 350 ℃ i mua i te mahi whakapiri;

2. He mea nui ki te horoi i te waikura, te unahi hinu, te wai, me nga poke i runga i nga waahanga whakapiri i mua i te whakapiri.
