TIG welding yakatanga kugadzirwa muAmerica (USA) muna 1936, inozivikanwa seArgon arc welding.TIG inobvumira majoini emhando yepamusoro-welded kuti agadzirwe ane inert gasi anotsigira ane akachena welding mhinduro.Iyi nzira yewelding ndeye-se-chinangwa-welding maitiro maererano nemidziyo inoshandiswa, ukobvu hwemadziro, uye nzvimbo dzewelding.
Mabhenefiti eiyi nzira yewelding arikugadzira zvisingaite chero spatter uye mashoma anosvibisa uku achivimbisa yepamusoro-giredhi welded joint kana ikashandiswa nemazvo.Kudyiswa kwezvinodyiwa zvewelding uye zvazvino hazvina kupindirana, saka izvi zvinoita kuti TIG ikwane kune welding root pass uye positional welding.
Nekudaro, TIG welding inoda welder akanyatso dzidziswa kuti aishandise neruoko rune hunyanzvi uye ruzivo rwemashandisirwo chaiwo emagetsi uye amperage.Izvo zvichatsigira yakachena uye yakanakisa TIG welding mhedzisiro.Uye ini ndinofunga aya ndiwo mapoinzi eTIG welding disadvantages.
Sezvauri kuona mumufananidzo uyo, mushure mekunge wadzvanya switch yetochi gasi rinotanga kuyerera.Uye kana muromo wemwenje unobata pamusoro pesimbi, pfupi pfupi inoitika.nekuda kwehuremu hwazvino kumucheto wetochi, simbi inotanga kunyungudika painobatika uye arc inobatidza, hongu, yakafukidzwa nekudzivirira gasi.
KUGADZIRA GASI ZVINODZORERA / KUFAMBA
Mwero wekuyerera kwegasi uri mul/min uye zvinoenderana nekukura kwedziva reweld, dhayamita ye electrode, dhayamita yemuromo wegesi, chinhambwe chemuromo wesimbi, mafambiro emhepo akatenderedza uye rudzi rwegasi rinodzivirira.
Mutemo wakajeka ndewokuti 5 kusvika ku10 malita ekudzivirira gasi inofanira kuwedzerwa kune argon sekudzivirira gasi uye kune inonyanya kushandiswa tungsten electrode diameters, pamwero we 1 kusvika 4 mm paminiti.
TOCH POSITION
Sezvo muMIG Welding, nzvimbo yemwenje, paunoshandisa nzira yeTIG Welding, inokoshawo zvikuru.Nzvimbo yemwenje uye tsvimbo ye electrode ichakanganisa mhedzisiro yewelding.
Iyo Electrode pachayo ndeye welding inodyiwa inoshandiswa panguva yeTIG welding.Welding consumables inowanzosarudzwa nenzira imwechete nemhando yesimbi.Nekudaro, nekuda kwezvikonzero zvemetallurgical, zvinodikanwa kuti izvo zvinobatisa zvinoshandiswa zvitsauke kubva kune simbi yemubereki kana zvimwe zvinhu zvealloying zvichishandiswa.
Kudzokera kunzvimbo yematochi.Iwe unogona kuisa nzvimbo dzakasiyana dzeTIG torch uye tsvimbo ye electrode paunenge uchitsvaira majoini akasiyana esimbi.Saka chinzvimbo chemwenje chinoenderana nerudzi rwemajoini esimbi.Ndinoreva kuti kune mana ekutanga simbi majoini akadai se:
T- Joint
Corner Joint
Butt Joint
Lap Joint
Iwe unogona kuisa mamwe eaya ma torch zvinzvimbo kumabasa aunoda kupedzisa.Uye kana iwe uchinge wajaira akasiyana simbi majoini welding torch zvinzvimbo, ipapo iwe unogona kudzidza nezve welding paramita.
WELDING PARAMETERS
Paunenge uchisarudza iyo welding parameters, zvinofanirwa kucherechedzwa kuti ikozvino chete yakaiswa pamushini we welding.Iyo voltage inotarirwa nearc kureba, iyo inochengetwa neanopisa.
Naizvozvo, iyo yakakura arc kureba inoda yakakwira arc voltage.Welding current ye45 amperage per mm yehukobvu hwesimbi inoshandiswa sereference value yezvino inokwana simbi yewelding kuti ipinde zvizere.
