MMA: āhuatanga me whakarōpū

Manual fehokotaki'anga pewa te pera ingoa hoki nga mahi e hiahiatia ana katoa welder mātanga ā. Ko ia te kawenga mō te takahi ia me te patururaa i te pewa, ko te kaupapa pewa o te whakapā i runga i te wā e hiahiatia ana, te supply o electrodes hou hei utu o whakamahia. Tei kounga Weld i runga i te pūkenga o te welder. Me ki whakakā hohoro te pewa, ki te āta aroturuki pera e ko te taua tona roa, me te ki te whakaputa i te fehokotakianga ōrite o te wahi e rua.

MMA kua he tetahi whakarōpū. Hei tauira, kia rite ki te maha o electrodes whakamahia ki te Weld wehewehe kotahi e rua ranei electrodes, me te maha-kawehiko. E toru-wāhanga, me te kotahi-wā pewa, kia te pūāhua nāianei AC DC ranei.

fehokotaki'anga tēnei wā whānui ki tauutuutu nāianei tika ranei te whakamahi i te kawehiko whakapau. O te akoranga, i reira e maha ngā huarahi rerekē ki te hono i te wahi i te kakano ia. Hei tauira, ki te hanga i ngā momo rerekē o te hononga (flanged taha). Hei whakanui i hua tūtohutia te whakamahi o electrodes o te kurupae, me fehokotaki'anga o ngā alloys me konganuku kore-ferrous he electrodes Tungsten.

MMA kua he tukanga ahumahi motuhake. A, no te e whakamahia kakano ia electrodes ngā wahi, e taea e whakapau me te nonconsumable. Ko te mua kia hanga o te waea ki te paninga motuhake. he tika taua riringi mo te tohu tiketike o te pūmautanga o te pewa hiko whakarato i tētahi para mata whakarewa me waikura e tiaki te poka Weld i pāhekoheko ki te taiao, me ki te tiaki i te pewa i te rohe o te pāhekoheko ki te rangi.

Ka taea te whakamana Manual fehokotaki'anga TIG i ngā āhuatanga ambient me ngā hau. Hei tauira, ā hauhauhā-pewa fehokotaki'anga (i roto i te taiao o hauhauhā), fehokotaki'anga i roto i te rangi, me te t. D.

E ai ki a GOST 9466-75, kua wehea nga electrodes ki te maha momo.

1. Na roto i te whakarite:

• me waro iti-koranu steels hanganga;
• alloys maitai;
• wera-ātete maitai koranu;
• nui-koranu steels hanganga.

2. E ai ki te momo me te waitohu:

• kara;
• ritenga.

3. Ka rite ki te matotoru o te paninga maputia e:

• kikokore;
• toharite;
• matotoru;
• rawa matotoru.

4. Na momo paninga kawehiko:

• waikawa;
• rutile;
• cellulose;
• pani paura rino.

5. tūranga mokowā whakaaetia o nga electrodes:

• mo tetahi kai;
• mo tetahi, ki te kahore fehokotaki'anga ā-poutū;
• mo te whakapae raro me runga i te waka rererangi poutū;
• mo te raro "i roto i te kaipuke."

6. te wehenga tawhiti o te nāianei fehokotaki'anga whakamahia:

• tika;
• whakataka;
• tetahi.

7. Na te āhua o te nāianei fehokotaki'anga:

• pūmau;
• AC.

fokotu'u MMA e whakarewa paiherea nei te electrodes, me whai i te hanganga matū e ōrite ana ki ona whakaritenga. Ko te āhuatanga pūkaha o te hua Weld me kawea reira me Weld whakarewa kia rite ki GOST 9467-75.
