MMA, sifooyinka iyo dirka

Buugga alxanka ARC waxaa sidaas la odhan jiray, maxaa yeelay, dhammaan falalka baahan yahay alxanka takhasus gacanta. Wuxuu mas'uul ka yahay hurinta iyo joogtaynta lagu bedello, dhaqdhaqaaqa ARC ee xiriirka ee ku yaalla bareeg loo baahan yahay, bixinta of electrodes cusub halkii isticmaalay. tayada Weld ku xiran tahay xirfad ah ee alxanka ah. U baahan tahay in si deg deg ah u guban lagu bedello, si ay ula socdaan si dhererkiisu wuxuu ahaa isku mid, iyo sidoo kale in ay soo saaraan alxanka direyska oo ka mid ah laba qaybood.

MMA ayaa soocidda gaar ah. Tusaale ahaan, sidii ay tirada of electrodes loo isticmaalo in lagu kala saaro Weld hal ama laba electrodes, iyo ku-koronto badan. Waxaa jira saddex waji iyo qaanso-hal wajiga, qof hadda laga yaabaa in AC ama DC.

alxanka Currently baahsan la talantaalli ama hadda si toos ah iyadoo la isticmaalayo koronto ah consumable. Dabcan, waxaa jira siyaabo badan oo kala duwan in ay ku xidhmaan waslad by alxanka. Tusaale ahaan, si ay u sameeyaan noocyada kala duwan ee kala goysyada (geesaha flanged). Si loo kordhiyo wax soo saarka talinayaa isticmaalka electrodes dharsameeyaha, iyo alxanka ee Alloys kala duwan iyo biraha non-ferrous waa electrodes tungsten.

MMA leeyahay geeddi-socodka ah wax soo saarka gaar ah. Marka electrodes alxanka qaybo kala duwan ayaa loo isticmaalaa, kaas oo noqon kara consumable iyo nonconsumable. hore ee laga sameeyey ee xarigga la daahan gaar ah. xereen noocan oo kale ah waa lagama maarmaan u ah heerka sare ah xasiloonida of ARC korontada bixiyaan wasakh bay dusha biraha iyo oxides oo ilaaliyo pool Weld ka soo dhexgalo deegaanka, iyo si ay u ilaaliyaan arc ka aagga wajahda hawada.

Buugga alxanka TIG lagu samayn karaa at xaaladaha kala duwan daarmayaay'e iyo gaasaska kala duwan. Tusaale ahaan, buuga alxanka argon-ARC (jawi of argon), alxanka hawada iyo t. D.

Sida laga soo xigtay GOST 9466-75, electrodes ku kala qaybsan yihiin dhawr nooc.

1. By balan:

• iyo carbon low-daawaha steels oo dhisme ah;
• Alloys steel;
• kulaylka u adkaysta steel daawaha;
• -Daawaha sare steels dhismaha.

2. Sida ku cad nooca iyo brand:

• Heerka;
• caadadii.

3. Sida dhumucda daahan ee lagu buufiyaa:

• khafiif ah;
• celcelis ahaan,
• qarada waaweyn;
• gaar ahaan qaro weyn.

4. By daahan koronto nooca:

• acid,
• rutile;
• cellulose,
• daahan budo bir ah.

5. meel aan ollogga la ogolaan karo ee electrodes ah:

• waayo qodobada kasta;
• waayo, wax kasta, marka laga reebo alxanka Buugga taagan;
• waayo hoose siman iyo diyaarad taagan;
• waayo, xagga hoose "doonnida."

6. polarity ee alxanka hadda loo isticmaalo:

• si toos ah;
• noqonaynin,
• kasta.

7. By dabiiciga ah ee alxanka hadda:

• joogtada ah;
• AC.

MMA soo jeedisay in biraha kaas oo la welded electrodes, waa in ay leedahay Halabuurka kiimikada u dhiganta shuruudaha ay. Sifooyinka farsamo ee keentay ku Weld iyo Weld birta waa in la keenay waafaqsan GOST 9467-75.
