Kawa-atete ki te mata o te mata o te waea rewharewha
Kei te mohiotia ano te waea a Flux-cored hei waea paura, waea tubular, ka taea te wehewehe ki nga waahanga e rua o te tiaki hau me te tiaki hau kore.Ko te mata o te waea rewharewha he mea hanga ki te maitai waro iti, te rino koranu iti ranei me te kirihou pai.Ko te tikanga whakangao, ka hurihia te tira maitai ki te ahua o te waahanga U-ahua, katahi ka whakakiia te paura whakarewa ki roto i te riu maitai U-ahua i runga i te inenga, ka hurihia te tira maitai e te mira pehanga, ka mutu ka toia. ki nga korero rereke o te waea rewharewha.I roto i te katoa, ka taea te wehewehe i te waea rewharewha ki te waea rewharewha whakamarumaru whaiaro me te waea rewharewha whakamarumaru hau.I te nuinga o te wa ka wehea te waea rewharewha kua parea te hau ki nga punaha parapara e rua, ara, te waikawa me te taketake (T 1 me T 5).He pai te mahi o te waea rewharewha o te waikawa slag, a ka taea te whakamahi i nga waahi katoa.Ko te mea tino whanui te whakamahi i nga rawa whakaraerae tino pai i roto i te umanga hanga kaipuke.He pai te purenga o te whakarewa whakarewa o te waea rewharewha taketake, a ka taea e ia te whiwhi i nga mahi tino pai ma te whakatika i te tikanga tika, he pai mo te tuunga o te whakapiri papatahi me te whakakii awhi.
