I roto i te ahumahi hanga, ko te kounga o te whakarewa te mea e whakatau tika ana i te roa o te hua, te haumaru, me ngā utu whakahaere. Mō ngā kaihoko me ngā kaiwhakahaere wheketere e rapu ana i ngā rauemi whakarewa maha, ko te waea totoka te mea nui hei whakarerekētanga kēmu e whakanui tonu ana i te kounga o te whakarewa me te hangai ki ngā tono whakaputa hou. Ka whakamāramahia e tēnei tuhinga te whakapai ake a te waea totoka i te kounga o te whakarewa, ā, ka aro atu ki ngā pātai matua e pā ana ki te ahumahi e tino arohia ana e koe.
He Tirohanga Poto mō te Waea Totoka mō te Whakarewa Ahumahi
Ko te waea totoka e pā ana ki tētahi waea konganuku ōrite e whakamahia ana hei rauemi whakakī me te hiko kawe i roto i ngā tukanga whakarewa pēnei i te whakarewa GMAW me te MIG. He rerekē ki te waea he pūtake-rerenga, he totoka te wāhanga whakawhiti me te hanganga matū ōrite, e whakatakoto ana i te turanga mō te mahi whakarewa pumau. Ahakoa he tino māmā te tukanga whakaputa ki te whakataurite ki ētahi atu waea whakarewa, me tino whakahaere te kounga o te parakore o ngā rauemi me te tika o ngā āhuatanga kia tutuki ai ngā paerewa ahumahi—he mea nui tēnei mō ngā kaihoko e arotake ana i ngā kaiwhakarato.
Ngā Painga Matua: Me pēhea teWaea MārōWhakarei ake i te Kounga Whakarewa
1. Te Hanganga Pūmau o te Whakarewa me te Whakaiti i ngā Koha
Mā te hanganga ōrite o te waea totoka ka pumau te mura o te pewa me te whakawhiti pata ōrite i te wā e whakarewa ana. Mā tēnei ōritetanga ka whakaitihia ngā hapa noa pēnei i te porosity, ngā kapiti, me ngā pīrere whakarewa kāore i te ōrite—ngā take e pāngia ana e te maha o ngā rauemi whakarewa kounga iti. Mō ngā ahumahi e hiahiatia ana pēnei i te hanga motuka me te hanga mīhini taumaha, ko te tikanga he iti ake ngā mahi anō, he iti ake ngā tere para, me ngā whakarewa e tutuki ana i ngā whakaritenga āhuatanga miihini tino kaha. Hei tauira, i te wā e whakarewa ana i te maitai kaha-teitei 1000 MPa, me whiriwhiri tikawaea totokaka taea te whakatutuki i te kaha kume neke atu i te 1080 MPa me te pakari pānga pāmahana iti tino pai.
2. Hototahi ki te Whakaputa Aunoa
Kei te neke haere te hanga ahumahi hou ki te aunoatanga, ā, nā te mata maeneene o te waea totoka me te whānui ōrite e pai ai mō ngā pūnaha whakarewa karetao. Ka taea te whāngai waea pumau, ka whakaiti i te wā kore mahi i puta mai i ngā taura waea, ā, ka whakarite i te kounga whakarewa ōrite puta noa i ngā oma whakaputa nui. Mō ngā kaihoko e haumi ana ki ngā raina whakarewa aunoa, ka puta he pai ake te pai o te whakaputa, he iti ake ngā utu mahi, me te kounga putanga e taea te matapae - he mea nui mō ngā mahi tauine.
3. Te Whakapai Ake i te Kounga Whai Hua
Ki te whakataurite ki te waea he anga-rerenga,waea totokaHe iti ake te utu whakaputa, ā, kāore e hiahiatia he whakamaroke i mua. Ina honoa ki ngā hau tiaki utu iti pēnei i te CO₂, ka whakaitihia ngā utu whakarewa katoa mā te 40-50% ki te whakataurite ki te whakarewa ā-ringa, ki te whakarewa ā-ruku rānei. Mō ngā kaihoko e whakataurite ana i te kounga me te tahua, ka tukuna e te waea totoka he otinga utu-pai e kore e whakararu i te kounga whakarewa—ina koa mō ngā kaupapa whakaputa waenga ki te rahi.
Ngā Auahatanga Waea Totoka me te Whakarewa Ahumahi: Ngā Mea Me Mōhio Ngā Kaihoko
1. Ngā tono motuhake mō te ahumahi
Nā te maha o ngā whakamahinga o te waea totoka, he pai mō te whānuitanga o ngā rāngai ahumahi. I roto i te hanga waka, ka whakamahia mō te whakarewa i ngā anga tinana me ngā wāhanga nā te mea he kaha teitei me te mahi pumau. I roto i te hanga kaipuke me te hanga, he tino pai ki te whakarewa i te maitai hanganga me ngā paipa, he mea e kore e taea te tautohetohe i te roa o te whakarewa. He whānuitia hoki te whakamahi i roto i te hanga taputapu rererangi me te pūngao mō te whakarewa tika o te maitai kore waikura me te konumohe. Mō ngā kaihoko, mā te mārama ki ēnei āhuatanga tono ka āwhina i te whakarite kia rite te waea totoka kua tīpakohia ki ā rātou hiahia whakaputa motuhake.
2. Te Whakahāngaitanga o te Whakaputa Kakariki
Kei te whakawhāiti haere ngā ture taiao puta noa i te ao, ā, kei te anga whakamua te umanga whakarewa ki ngā mahi matomato. Mā ngā hua waea totoka matatau, pērā i te waea totoka kore-parahi, ka whakaitihia ngā tukunga paowa me te whakakore i te parahanga puehu parahi i te wā whakarewa, ka waihangahia he taiao mahi hauora ake. Mō ngā kaihoko e mahi ana i ngā rohe he tino pakari ngā paerewa taiao, mā te whiriwhiri i te waea totoka hoa-taiao ka āwhina i te whakarite kia tutukihia ngā whakaritenga me te whakarei ake i ngā tohu pumau a te kamupene.
Tohutohu Whaihua mō ngā Kaihoko: Te Kōwhiri me te Whakamahi i te Waea Totoka
I te wā e whiriwhiri ana i te waea totoka mō ō hiahia hangahanga, arotahi ki ngā āhuatanga matua e toru: 1) Te hototahitanga o ngā rauemi—te whakataurite i te hanganga matū o te waea ki te konganuku turanga Ngā whakaritenga o te tukanga whakarewa—te whakarite kia tika te waea mō ō taputapu o nāianei Te pono o te kaiwhakarato—te whakatairanga i ngā kaiwhakarato me ngā tukanga whakahaere kounga tino pakari kia kore ai e rerekē te mahi o ia puranga.
I te whakamahinga, kia mau tonu te rere o te hau ārai kia kore ai e poke te whakarewa, ā, kia whakarerekētia te ia whakarewa me te pāmahana whakamahana i mua i runga i te matotoru o te konganuku turanga. Hei tauira, ko te whakarewa i te maitai kaha-teitei 1000 MPa me te waea totoka ka tutuki i ngā hua tino pai i te ia 260 A me te pāmahana whakamahana 100 ℃.
Whakamutunga: Waea Totoka hei Poutokomanawa mō te Whakarewa Ahumahi Kounga Teitei
