Ko te hikohiko he waea whakarewa kua pania, ā, ko te tikanga me hanga mai i tētahi rauemi he rite ngā āhuatanga me te hanganga ki te whakarewa e whakarewaina ana, ā, he maha ngā mea hei whakaaro māu mō te whiriwhiri i te hikohiko tika mō tāu kaupapa.
Ahakoa ka taea te whakamahi i ngā irahiko SMAW, "piri" rānei, ā, ka uru ki te whakarewa, ko ētahi atu irahiko (pērā i ērā e whakamahia ana mō te whakarewa TIG) kāore e taea te whakamahi, arā, kāore e rewa, ā, kāore e uru ki te whakarewa. He hononga. Me wehe te hononga, i ēnei wā, me whakamahi i te irahiko.
E mōhio ana mātou o Eng-weld he mea nui te whiriwhiri i te hiko tika mō te kaha o te whakarewa, te kounga o te whakarewa, te whakaiti i te tauhiuhi me te horoi.
Ko ngā irahiko cellulose he irahiko whakarewa kua pania ki te takotoranga kei roto ngā rauemi rauropi. Ko te tikanga he cellulose te 30% o te taumaha o te paninga, engari i ētahi wāhi o te ao ka tāpirihia pea te cellulose me te paraoa rakau ki te paninga hei whakaiti i te nui o te cellulose parakore.
Ka pirau ngā momo matū waro i roto i ngā irahiko i roto i te pewa hei hanga i te hauhā waro, te hauhā waro me te hauwai, ā, ka whakanuia e ēnei katoa te ngaohiko i roto i te pewa, ka hua ake he pewa kaha ake, he pewa mārō ake. Nō reira, ka taea e ngā irahiko cellulose te uru atu ki te 70% hohonu atu i ngā irahiko hototahi me te reiti iahiko ōrite.
He mea hanga noa iho tēnei me te paninga angiangi, waenga rānei, ahakoa ka puta he para ka taea te tango i muri i te otinga o te tukanga whakarewa, ka hua ake pea he nui ngā ngaronga o te paru. Heoi, he tino pai te kaha whakarewa poutū ki raro me te kaha uru o tēnei hiko nā te whakakī i te āputa i roto i te paninga.
Ko te irahiko hauwai iti he mea whakamahi mā te whakarewa pewa ārai hau (SMAW) me te ihirangi wai o raro iho i te 0.6%, ki te whakaritea ki te 4-6% o ngā irahiko cellulosic tuku iho.
Ko te tikanga, ko ngā irahiko iti te hauwai pērā i te irahiko tokotoko E7018 ka whakarato i te iti o te tauhiuhi ki ngā kaiwhakamahi me te pewa maeneene, pumau, me te marino. Nā ēnei āhuatanga ka waiho ēnei irahiko hei whiringa pai mō ngā kaiwhakarewa mohio me ngā tīmatanga. Mā ngā āhuatanga o ēnei irahiko whakarewa whakakī ka whakarato i te kaiwhakahaere pewa pai ki te kaiwhakarewa, ā, ka whakaitihia te hiahia mō te horoi i muri i te whakarewa.
He rerekē ngā irahiko iti-hauwai ki ētahi atu irahiko pērā i te E6010, i te E6011 rānei, he pai ake te tere o te whakatakotoranga me te urunga o ngā irahiko hauwai iti, e āhei ai te kaihārai ki te tāpiri atu i te konganuku ki te hononga i ngā wā katoa, e whakapai ake ana i te kaha o te whakarewa me te karo i ngā hapa whakarewa pērā i te kore urunga.
I te nuinga o te wā, ka whakaratohia e ngā hikohiko maitai ngawari he pewa marino, he pūmau hoki, he iti te urunga, he mea tino pai mō te hono i ngā āputa whānui me ngā tono pepa angiangi. Heoi anō, he rerekē ngā momo hikohiko maitai ngawari, he rerekē ngā āhuatanga o ia momo, ā, he pai ake mō ngā tono rerekē.
Hei tauira, ko te karaehe 6013 he hiko maitai ngawari whānui e whakarato ana i te urunga hohonu me te pupuri i te pewa maeneene me te pumau. He ngawari te hanga anō i te pewa, he ataahua te hononga whakarewa, he iti ake te tauhiuhi, he ngawari te whakahaere i te paru, he pai mo te whakarewa poutū ki raro.
Ko te hiko pewa 7018, i tētahi atu ringa, he hiko maitai ngawari i hangaia mō te whakarewa i ngā rauemi maitai waro kaha-teitei. He maha ngā wā ka whakamahia tēnei hiko mō te whakarewa hanganga nā te ātete o te whakarewa ki te pakaru. Engari he nui te para ka puta mai i tēnei, kāore e pai mō te whakarewa poutū ki raro.
Ko te hiko hiko rino ngawari whakamutunga ka kitea e tātou ko te 6011. Mā tēnei hiko hiko hohonu maha-whakamahinga ka puta he pewa maeneene, he pūmau hoki ina whakarewahia te rino ngawari kua whakapūmautia me ētahi atu rino koranu iti. Ka hangaia e tōna paninga he pewa kaha o te urunga hohonu, ā, he angiangi te paparanga para, ā, he ngāwari ki te tango.
Pērā i ngā irahiko kē atu i kitea i runga ake nei, he maha ngā momo irahiko kowiri tira, he rerekē paku nei ia momo i te mea o mua.
I konei ka tirohia e tātou ētahi momo hiko kowiri tira e toru, 308, 309 me te 316, me te wā me whakamahi ai.
Mena kei te whakamahi koe i ngā reanga 301, 302, 304, 305 me ngā koranu whakarewa CF-3 me CF8, ka tūtohu mātou kia whakamahia e koe te 308L, tae atu ki ngā irahiko ER308LSi. He pai rawa atu ēnei irahiko kowiri tira mō ngā maitai kowiri tira austenitic, engari mō ngā tono pēnei i te whakaputa hiko, ka tūtohu mātou i te irahiko 308H nā te mea he pai ake te ātete ngoki o tēnei irahiko waro teitei i ngā pāmahana teitei.
Mēnā ka honoa te maitai ngawari, te maitai ngawari rānei ki te maitai kore waikura, whakamahia te 309L, tae atu ki te ER309LSi. Pērā anō hoki mō te honoa o ngā maitai kore waikura rerekē pērā i te maitai kore waikura 409, 304L rānei. Haunga tēnei, me whakamahi hoki ēnei hei hono i ngā konganuku turanga 309.
Mēnā e whakamahia ana ngā konganuku turanga 316L me te 316 me ō rāua rite whakarewa CF-8m me te CF-3M, ko te 316L anake me whakamahi hei konganuku whakakī, tae atu ki te ER317LSi.
Ka taea e ētahi tono 308L te whakakapi i te 309L hei konganuku whakakī nā te mea kāore e hiahiatia he molybdenum, he rerekē ki ngā tono 316, 316L rānei e hiahiatia ana he molybdenum, nō reira kāore e taea te whakakapi i te 309 ki te 316.
E ai ki tā tātou i kite ai i runga ake nei, he whānuitia ngā momo irahiko e wātea ana. He rerekē ngā āhuatanga o ia irahiko, nō reira he rerekē, he ahurei hoki. I te wā e mahi ana i tētahi mahi whakatikatika me te tiaki, me tino tupato kei a ngā irahiko e whakamahia ana ngā āhuatanga e hiahiatia ana.
Tuatahi, whakatauhia te momo konganuku ka whakatikahia, ka tiakina rānei e koe. Kātahi ka whakatau koe mēnā he hiko whānui, he hiko motuhake rānei e hiahiatia ana. Kia whiwhi koe i ēnei mōhiohio katoa, ka taea e koe te tīmata ki te whakapiripiri. Ki te kore, ā, ki te whakamahi koe i ngā hiko hē, tera pea ka pakaru tō whakapiripiri, ka tahuna rānei te konganuku e mahi ana koe.
