Waea Toka GMAW AWS ER70S-6 CO2 migwaea whakapiri
NGĀ TONO:
Whakamahia mo te whakapiri 500MPa iti koranu maitai kotahi me te maha-haere fehokotaki'anga;hoki mo te tere tiketike pereti kikokore, paipa raina maitai fehokotaki'anga.
He pai mo te whakapiri a-ringa, te raima aunoa me te miihini karetao, penei i te miihini hinu, nga miihini warou taumaha, nga oko pehanga,
oko hinu-matū, tinana kaipuke,, hanganga maitai hanga, etc.
NGĀ KAUPAPA:
Ko tenei waea GMAW mo te Rm 500MPa taumata waro maitai me te hau maru CO2, M21 ranei.
He iti te mokowhiti, he ahua ataahua, he pai te whakatakotoranga me te ngawari o te porosity whakarewa.He pai nga tuunga katoa.
WHAKATOKANGA:
1. Ko te waikura, te hinu, te wai me etahi atu poke o te waahi weld me tango i mua i te whakapiri.
2. Ko nga ahuatanga miihini o nga konganuku weld katoa ka whakatauhia ma te whakauru wera, ko te tikanga ka pai ake te whakauru wera iti i te rahi.
NGA TUNGA WELDING: PA, PB, PC, PD, PE, PF
