Mkulu zamakono argon kuwotcherera

The ya mankhwala ntchito kunyumba makampani, anapanga zitsulo ndi kasakaniza wazitsulo awo. Kwa cholimba ndi apamwamba kugwirizana okhazikika katundu zitsulo njira bwino - ndi maphatikizidwe kuwotcherera. Mwa njira, ndi wotsika mtengo ndipo amalola kupeza yabwino china chotulutsa, argon kuwotcherera akhoza dzina lake. Umenewu ndi mtundu wa kuwotcherera Arc. Zagwiridwa ndi Arc moto pakati pa anthu osakhala consumable (kawirikawiri - tungsten) elekitirodi ndi workpiece zitsulo. The elekitirodi yakwera mu burner ndi kunja amaperekedwa kwa zone limatsogolera zakuthupi filler si mbali ya dera magetsi. M'mbali mwa zitsulo m'munsi ndi chuma filler isungunuke ndi plasma Arc ndi kupanga msoko. Kuti china chotulutsa dziwe mwa burner nozzle mu mode basi umaperekedwa mpweya inert ndi argon. Ndi pafupifupi samalowa mu mogwirizana mankhwala ndi zitsulo lamkuwa ndi mpweya anapanga m'dera Arc. Chifukwa chakuti Ari ndi 38% yolemera kuposa mpweya, izo adzatsika, chimakankhira mpweya wa mlengalenga m'dera china chotulutsa, motero kuteteza ndi kuteteza pakutchulidwa ya zopindika olowa welded. Kuchepetsa china chotulutsa porosity, mwina zidzawonjezedwa kwa argon wa 3-5% mpweya, ndiye chitetezo zitsulo ukugwirira.

Argon kuwotcherera amapereka mapangidwe china chotulutsa ndi inki ndege kapena kutengerapo globular zitsulo. Globular kutengerapo zimachititsa kupezeka onse ndipo sangathe kukwaniritsa ndondomeko zisathe kuwotcherera. makhalidwe zopangapanga analandira pamene msoko uyu aipa koposa mu zoopsa zoyenera kuwotcherera mu NKHA _2. Inkjet zitsulo kutengerapo amapereka argon kuwotcherera pa kuwotcherera mafunde pa kulankhulana Ine = 260A. Mu ndondomekoyi ndi kuwotcherera amakhala khola china chotulutsa khalidwe liti bwino. Koma kugwiritsa ntchito mkulu amperage zambiri ikufanana ndi zofunika zamakono za ndondomeko (mwachitsanzo, mosayenera likamatenthetsa workpiece ndi chimasintha katundu zitsulo alloyed). Choncho m'pofunika kugwiritsa ntchito kusintha amapereka mphamvu. Zimenezi zimathandiza kusinthana ndi ndege za zitsulo kutengerapo kale mafunde kulankhulana bwino Ine = 100A.

poyatsira ntchito sanali consumable elekitirodi adatengedwa ndi chipangizo wapadera - ndi oscillator olumikizidwa ku kufanana ndi gwero mphamvu. Pamene argon kuwotcherera amachitidwa pa alternating panopa, pambuyo poyatsira waku Arc ndi kugwiritsa ntchito mode oscillator stabilizer, kudyetsa mu nyemba Arc ndi kusintha polarity. Izi zipangitsa mtendere wa Arc lapansi.

Ngati ntchito panopa zonse, ndi cathode ndi anode amapezeka m'goli kutentha kutulutsidwa (70% - pa anode a). Choncho, steels, kasakaniza wazitsulo titaniyamu ndi miyala ina kuposa zotayidwa, ntchito molunjika polarity kudzapeza preform isungunuke. Al kuwotcherera amachitidwa pa alternating panopa, amene amalola kuononga okusayidi film, popanda kutenthedwa mankhwala.

Magawo unapangidwa zosapanga steels kuwotcherera, zotayidwa ndi kasakaniza wazitsulo ake Angagwiritsidwenso ntchito argon-Arc kuwotcherera ndi elekitirodi consumable. Komabe, ukulu ndi kuchepera kwambiri kuposa ndi maelekitirodi tungsten.

Izo ntchito zonse zamanja ndi zodziwikiratu argon kuwotcherera. Mwa ubwino wake monga kubereka pawiri mankhwala a makulidwe kakang'ono popanda zipangizo china chotulutsa filler, ntchito njira kupeza pamwamba. Njira kwambiri kuwotcherera mbuyo malo a mipope zitsulo. Popangidwa ndi china chotulutsa ali magawo zabwino zamakono. Argon Arc kuwotcherera - luso, mankhwala abwino kwambiri steels alloyed, titaniyamu kasakaniza wazitsulo, zotayidwa.

Chifukwa kuphweka wachibale njira, argon kuwotcherera manja palibe okha owotcherera akatswiri. Pankhaniyi, chifukwa cha kuchuluka ka ntchito, osati zofunika otsika zokolola za ndondomeko, amene zimasokoneza ntchito yopanga zikuluzikulu.
