Kei te whakamahia whanui te kupenga welding i roto i te umanga, ahuwhenua, whakatipuranga, hangahanga, kawe waka, maina me etahi atu waahanga.Pērā i ngā whakangungu rakau, pene kararehe, pene puawai, tutaki matapihi, taiapa uru, whare heihei, kete hua manu me nga kete kai a te tari whare, kete pepa me nga taonga whakapaipai.
Te kupenga fehokongahe mea hanga o te kounga teitei iti waro maitai waea fehokotaki'anga, a ka whakakikorua matao (electroplating), whakakikorua wera, PVC kirihou me te tahi atu passivation mata, plasticizing maimoatanga, mata maeneene, mata kākahu, fehokotaki'anga wahi u, machining rohe pai pūmautanga mahi, te waikura. ātete, waikura ātete.Āhuatanga: kowiri tira kowiri tira kōwhiringa kupenga o te kounga teitei kowiri tira waea rarangi fehokotaki'anga, atu waikawa, ātete alkali, u fehokotaki'anga, ataahua, whakamahia whānuitia āhuatanga.
Ko te anticorrosive pai te rongonui i roto i te whangai, te maeneene me te maamaa o te kupenga, te whakanui ake i te ahua me te ahua, ka taea te whakapaipai, na tenei ahuatanga e whakaatu ana i roto i te umanga maina, na te kounga teitei me nga rauemi waro iti hei rauemi mata, ki te hanga ahurei mata rino mata mata kore e whai ngāwari, te whakatau i tona plasticity i roto i te tukanga whakamahi, Ka taea te whakamahi te reira mo te hanga hohonu tukatuka o te hangarau pūmārō, te piu puranga o te tinana taiepa matatini, ārai leakage raro me te ārai pakaru, kupenga marama tinana, kia iti ake tenei utu i te utu o te mata rino, ka nui ake te mohio ki tana ohanga me te painga.
