Kusarudza michina yekupa emhando yepamusoro uye kugadzirwa mukushanda kwewelding kunodarika simba remagetsi kana pfuti yemagetsi - zvinoshandiswa zvinotora basa rakakosha zvakare.Mazano ekuonana, kunyanya, anogona kuita mutsauko wakakura pakati pekumhanyisa maitiro uye kuwedzera nguva yekudzikisa kugadzirisa matambudziko.Kusarudza iyo chaiyo yekubata tipi yebasa kunogona kukanganisawo purofiti yekushanda kwewelding.
Mazano ekubata ane basa rekuendesa welding ikozvino kune waya sezvainopfuura nekugadzira iyo arc.Zvakakwana, waya inofanira kudyisa kuburikidza nekushomeka kushoma, ichiri kuchengetedza magetsi.
Mazano ekuonana anogona kuita mutsauko wakakura pakati pekumhanyisa mashandiro ewelding uye kuwedzera downtime kugadzirisa matambudziko, uye anogona zvakare kukanganisa pundutso yekushanda kwewelding.
Nechikonzero ichocho, zvinogara zvakakosha kuti usarudze yemhando yepamusoro yekusangana tipi.Nepo zvigadzirwa izvi zvichigona kudhura zvishoma pane zvigadzirwa zvegiredhi diki, pane kukosha kwenguva refu kuramba mutengo wekutenga wepamberi.
Uyezve, matipi emhando yepamusoro-soro anowanzo kugadzirwa kuti awedzere kushivirira kwemagetsi, achigadzira zvirinani kupisa uye magetsi.Vanogonawo kuve nepakati pepakati pakatsvedzerera, zvichikonzera kukweshana kushoma sezvo waya ichipinda.Izvi zvinoreva kuenderana kudyisa waya nekudhonza kushoma, izvo zvinobvisa zvingangoitika zvemhando.
Mazano epamusoro-soro ekuonana anogonawo kubatsira kuderedza kupisa (kuumbwa kweweld mukati metipi yekusangana) uye kubatsira kudzivirira arc inorasika inokonzerwa nekusaenderana kwemagetsi conductivity.Vanowanzogara kwenguva refu.
Kusarudza chinhu chakakodzera uye kubereka saizi
Mazano ekubata anoshandiswa semi-otomatiki MIG welding anowanzo kuumbwa nemhangura.Ichi chinyorwa chinopa yakanaka yekupisa uye yemagetsi conductivity kuti ibvumire kuchinjika ikozvino kuendesa kune waya, nepo ichive yakasimba zvakakwana kuti imirire kupisa kunogadzirwa panguva yewelding process.Kune marobhoti welding, mamwe makambani anosarudza kushandisa inorema-duty chrome zirconium contact tips, sezvo izvi zvakaoma kudarika mhangura uye zviri nani kutsungirira kuwedzera arc-on nguva ye automated application.
Muzviitiko zvakawanda, kushandisa zano rekusangana rinoenderana nehukuru hwewaya kunotungamira kune zvakanakisa mhedzisiro.Zvisinei, kana waya ichidyiswa kubva mudhiramu (semuenzaniso makirogiramu 500 zvichikwira) uye/kana pakushandisa waya yakasimba, chidimbu chekubata chinonatsiridza mashandiro anoita welding.Nekuti waya kubva pachigubhu inoita kunge isina kukandirwa kushoma, inodyisa kuburikidza netipi yekusangana ine kushoma kana kusabatana - kuve nediki bhora rinowedzera kudzvanywa pawaya, zvichiita kuti magetsi awedzere.Kuisa pasi petipi yekubata, zvisinei, kunogona kuwedzera kukakavara, zvichikonzera kusarongeka kwewaya kudya uye, pamwe, kutsva.
Sezvineiwo, kushandisa yakawandisa tipi kunogona kudzikisa ikozvino kutamiswa uye kuwedzera tipi tembiricha, izvo zvinogona zvakare kutungamira mukutsva kwewaya.Kana usina chokwadi chekusarudza saizi yakakodzera yekubata tipi, bvunza anovimbika anoshandisika mugadziri kana welding distributor.
Semaitiro akanakisa, gara uchitarisa kubatana pakati petipi yekubata uye gasi diffuser kuti uve nechokwadi kuti yakachengeteka.Saizvozvo, kubatana kwakachengeteka kunoderedza kusagadzikana kwemagetsi kunogona kutungamirira mukupisa.
Kunzwisisa contact tip recess
Bata tip recess inoreva chinzvimbo chetipi yekubata mukati memhino uye chinhu chakakosha chinopesvedzera weld mhando, kugadzirwa uye mutengo mukushanda kwewelding.Kunyanya, chaiyo yekubata tipi recess inogona kuderedza mukana wekunyanya spatter, porosity uye kupisa kana kuputika pazvinhu zvitete.Inogonawo kubatsira kuderedza kupisa kunopenya kunogona kukonzera kutadza kubata tip.
Bata tip recess inokanganisa zvakananga waya stickout, inonziwo electrode kuwedzera.Iyo yakakura kudzika, iyo yakareba iyo stickout iri uye yakakwirira yemagetsi.Nekuda kweizvozvo, izvi zvinoita kuti arc isanyanya kugadzikana.Nechikonzero ichocho, yakanakisa waya yekunamira kazhinji ndiyo ipfupi inotenderwa kushandiswa;inopa arc yakagadzikana uye zviri nani kudzika-voltage kupinda.Yakajairika yekubata tipi nzvimbo ndeye 1/4-inch recess, 1/8-inch recess, flush uye 1/8-inch yekuwedzera.Tarisa kuMufananidzo 1 wezvikumbiro zvinokurudzirwa kune yega yega.
| Recess/Extension | Amperage | Wire Stick-Out | Process | Notes |
| 1/4-in.Kuzorora | > 200 | 1/2 - 3/4in. | Spray, high-current pulse | Metal-cored wired, spray transfer, argon-rich rakasanganiswa gasi |

Kuwedzera hupenyu hwemazano
Kutadza kubata tip kunogona kubva kune akati wandei pesvedzero, zvinosanganisira kutsva, kupfekwa kwemagetsi nemagetsi, nzira isina kunaka yewelding operator (semuenzaniso, kusiyanisa kwemakona epfuti uye kubata-tip-to-work-distance [CTWD]), uye kupisa kunoratidza kubva base zvinhu, izvo zvinowanzoitika mukuomarara kuwana weld majoini kana nzvimbo dzakavharirwa.
Hunhu hwewaya iri kushandiswa hunogonawo kukanganisa hupenyu hwekusangana.Waya yemhando yakashata kazhinji ine yakakandwa isingadiwe kana helix inogona kuita kuti idye zvisina tsarukano.Izvo zvinogona kudzivirira waya uye yekubata tip kubva pakubatana zvakanaka kuburikidza nebore, zvichikonzera kuderera conductivity uye yakakwirira magetsi kuramba.Idzi nyaya dzinogona kukonzeresa kutadza kubata tip kutadza nekuda kwekupisa, pamwe nehurombo hwearc mhando.Kuti uwedzere hupenyu hwekuonana mazano, funga zvinotevera:
• Shandisa madhiraivha akakodzera kuti uve nechokwadi chekudyisa waya.
• Wedzera kumhanya kwewaya uye kurebesa CTWD kuderedza kutsva.
• Sarudza mazano ekuonana ane nzvimbo yakatsetseka kudzivirira kutsemuka kwewaya.
• Cheka liner yepfuti yeMIG kusvika pakureba kwayo kuitira kuti waya ipfuure nemazvo.
• Kudzikira tembiricha yekushandisa, kana zvichibvira, kuderedza kupera kwemagetsi.
• Shandisa tambo dzemagetsi mapfupi kana zvichiita kuti uwane kudya kwewaya kwakapfava.Kana tambo refu dzemagetsi dzichidikanwa, edza kuderedza zvishwe mukati madzo kudzivirira kinking.
Mune zvimwe zviitiko, zvingave zvinodiwa kuti uchinje kumvura-yakatonhorera MIG pfuti kuti ubatsire kuchengetedza kumberi-kumagumo zvigadzirwa, kusanganisira yekubata tip, inotonhorera uye inomhanya kwenguva yakareba.
Makambani anofanirwawo kufunga nezve kuteedzera mashandisiro avo ekushandisa tipi, achicherekedza shanduko yakawandisa uye kugadzirisa zvinoenderana nedzimwe nzira dzekuzvidzivirira.Kugadzirisa iyi nguva yekudzikira nekukurumidza kupfuura gare gare kunogona kuenda kure mukubatsira makambani kudzikisa mari isingakodzeri yekutenga, ukuwo uchivandudza mhando nekubudirira.
