Rahi auau:
Ka tukuna e matou nga hua i roto i te ahua o te waea, te waea papaa, te tarai. Ka taea hoki e matou te hanga i nga mea e rite ana ki nga tono a nga kaiwhakamahi.
He waea kanapa, he waea ngawari–0.025mm~5mm
Acid pickeling waea ma:1.8mm~10mm
Waea waikura: 0.6mm~10mm
Waea papatahi:te matotoru 0.05mm~1.0mm,whanui 0.5mm~5.0mm
Tukanga:
Waea: Te whakarite i nga rawa → te whakarewa → te whakarewa ano → te hanga → te huri wera → te whakamahana wera → te maimoatanga o te mata → te tuhi (te huri) → te whakaoti i te maimoatanga wera → te tirotiro → te kete → te whare putunga
āhuatanga hua:
1) He pai te anti-oxidation me te kaha miihini i te pāmahana teitei;
2) He nui te parenga me te iti o te pāmahana o te parenga;
3) He pai te reelability me te hanga mahi;
4)He pai te mahi fehokotaki'anga
