Hauhauhā pewa fehokotaki'anga, ona momo me ngā āhuatanga

Hauhauhā Welding - he ahua o hiko fehokotaki'anga pewa. Ko tōna āhuatanga Ko e e wahi te tukanga fehokotaki'anga i roto i te hau e mangere, e ārai hāora o te whakarewa.

Ko te wāhi tukatuka e te i roto i te hau paruru, ngā o te huānga e whai ake nei: te matamata kawehiko me te wahi Weld rauemi filler tautuhi me te wera pānga rohe. Hauhauhā - hau e mangere kūpapa e kore nei e tauhohe ki te whakarewa i roto i te fehokotaki'anga me te whangai i roto i te rama pupuha kawehiko motuhake. ingoa Gas whai wāhi i roto i te tukanga, ka i te ingoa tenei momo o ngā wāhanga hononga.

TIG taputapu fehokotaki'anga ngā te kawehiko kore-whakapau, i hanga nei e ngā te o Tungsten. He tenei whakarewa whakangutungutu nga huru maitatai e hiahiatia katoa me ngā āhuatanga, na te maha whakamahia te reira i roto i tenei momo o te fehokotaki'anga.

I roto i te take i taua tukua te rauemi filler e i roto i te puka o te waea tokotoko ranei, i roto i te tukanga e wā rumakina ki te kaukauranga whakarewa. I roto i te mahi tū te kawehiko e te taiapa motuhake, eke nei i roto i te pupuha, hangaia hoki kai hauhauhā hau ki te rohe i reira kawea te fehokotaki'anga hauhauhā-pewa te roto. Taputapu, aua, a me te tu i te nāianei hiko e rere i roto i nga electrodes, me te pānga ngāwhā i te whakamahi o te hauhauā.

Heoi, e kore anake e whakaputaina i electrodes Tungsten. taea hoki te hanga ratou o kowiri tira me te konumohe. I roto i tenei whakaaro, e tahuri iho fehokotaki'anga pewa hauhauhā ki 2 momo:

1. Ki te kawehiko whakapau.
2. Ki te kawehiko kore-whakapau.

He ā, me te aunoa hauhauhā pewa fehokotaki'anga. Ki te whakamahia kawehiko fehokotaki'anga aunoa te anake toia me fehokotaki'anga ā- taea te whakamana kawehiko kore-whakapau.

Ko te tukanga hangarau o TIG fehokotaki'anga.

No te mea te hau e mangere e kore e tauhohe ki konganuku, me te te meka i ratou i runga i toharite 38% taimaha atu te hāora whakamahia mō te fehokotaki'anga, hauhauā ngāwari teke'i te rangi ki te poke houhou i te rohe fehokotaki'anga. mawehe tenei te hāora houhou o te Weld hua, e tino whakanuia ana te kounga o te hua, me ona huru maitatai rerehua.

Na roto i nāianei hiko kawehiko haere te i wahi paiherea. Tukutahi ki te tīmatanga o te wahi o tūemi nāianei tīmata rere hauhauhā roto i te pupuha pūwera. rere tukanga Taumai i te rohe o kakano ia rauemi filler, rewa nei e te wera tipu i haere nāianei.

Mai ārai hauhauhā arcing, he mea e tika ana ki te whakamahi i te pūrere motuhake i huaina he oscillator. Tenei pūrere whakarato te pātīmata pono o te pewa i te tikanga o ngātere nui-auau, me hoki faarahi te stabilization o rere pewa i te wa o te wehenga tawhiti hokinga whakamuri.

Ko te painga e nohoia ana e hauhauhā pewa fehokotaki'anga, he:

1. Te kaha.
2. Ko te matotoru iti o te Weld.
3. Ko te taea o kakano ia wahi, kahore rauemi filler.
