Tig-welding: features isicelo

Argon welding tig (T ungsten I nert G nje ), okanye ezingezo-eziphelayo electrode welding - xa lakhanya arc phakathi Tungsten electrode kunye iindawo welding. Ngenxa yoko, ethubeni arc kwenzeka transfer etyhidiweyo. Oku kube lula eziko arcing nokwandisa kakhulu uyazinza. Ngaphezu koko, tig-welding ukuze kuncitshiswe ukulahleka komphunga, akubandakanyi uchaphazele kunokwenzeka kwaye ithintela igesi ukusuka ifuthe kwikholam arc kwi etyhidiweyo. Ngenxa yoko, umgangatho weld bavuselwa kwinqanaba entsha, nobunzima kakhulu.

Tig-welding AC okanye DC, kwaye, xa kwimeko yokugqibela isetyenziswa kuphela wokwephuka ngqo, oko kukuthi, xa yesiphelo "dibanisa" kwiplagi welding, iindawo, nakuyo terminal "a thabatha" - a non-eziphelayo electrode. Imfuneko ukudibanisa ngale ndlela ngenxa yokuba ukuba terminal ababini, amathuba nobushushu elivelayo Tungsten metal elinjubaqa, yaye ngenxa yoko ukuqina kwayo tsakisi kakhulu. Ukongeza, oku kungabangela NOKUCUKUCEZA okanye ukunyibilika i electrode, nto leyo kunqandwa iziphene le weld.

Tig welding kuthetha izinto zilandelayo ezinkulu kuyilo yezityalo: ngumthombo AC okanye DC, arc somfanekiso, i oscillator, isixhobo imali ekhoyo ngokulungelanisa imeko, ubume wenkunkuma lwangoku, igesi vana solenoid, yaye isixhobo abathintela amacandelo yangoku.

Tig-welding yeyona hlobo jikelele ngesinyithi compound, ekubeni ivumela ukuba weld izinto ezahlukeneyo na isikhundla isithuba.

welding iindawo inkqubo High ifunyanwa yinyaniso yokuba owenziwayo ixesha elincinane ngakumbi kunalo naluphi na olunye uhlobo iwelding. Kulo mba, tig-welding isetyenziswa kuphela xa iimpawu umgangatho wafumana weld zibaluleke ngokugqibeleleyo.

Olona phawu olwahlula olu hlobo iwelding yinto yokuba lo argon olunyulu isetyenziselwa ukudibanisa ngokupheleleyo naziphi na izinto, ngelixa kulungiselelwa iintlobo baseleyo segesi kufuneka zikhethwe ngokungqinelana iintsimbi welding.

Tig-welding yinkqubo kunokuba nzima kwaye onzima. Ngoko ke, intlanganiso efunwa zentsimbi abaqeqeshiweyo ngokwaneleyo. Inkqubo obutsha kuya kufuna kuye dexterity ngokwaneleyo, ekubeni kuyimfuneko enye ngesandla ukunika unikezelo ezaneleyo ngexesha kwemathiriyeli lokufaka, ngoxa kwelinye icala aya kuba itotshi ukuwelda.

Xa ukhetha umatshini welding elolu hlobo kufuneka akhokelwe ingqalelo oku kulandelayo:

1. Kuyimfuneko ukuba ngaba kunako unikezelo amandla kumatshini welding.

2. Lixabise ukuntsonkotha kunye nemali lomsebenzi.

3. Thatha ingqalelo uhlobo yokusebenzisa yangoku: DC or AC.

Kufuneka wazi ukuba ezinye abatyhidi zingasetyenziswa nangoko kunye current esisigxina kunye alternating. Oku kuyimfuneko kuba welding ngezinto ezahlukeneyo, ezifana aluminiyam nensimbi. Abatyhidi babe uluhlu olubanzi iimpawu zangoku ukususela nge-3 500 A.
