Izvo zvakakosha kune vatsva vanogadzira welding kuti vamise nzira dzakakwana dzeMIG kuitira kuti uwane yakanaka weld mhando uye nekuwedzera chibereko. Maitiro ekuchengetedza akanyanya kukosha, zvakare. Zvakangokoshawo, zvisinei, kune vane ruzivo welding operators kuti vayeuke izvo zvakakosha kuitira kuti vadzivise kutora maitiro anogona kukanganisa kuita welding.
Kubva pakushandisa yakachengeteka ergonomics kusvika pakushandisa iyo yakakodzera MIG pfuti angle uye welding yekufamba kumhanya uye nezvimwe, yakanaka MIG welding matekiniki anopa mhedzisiro yakanaka. Heano mamwe mazano.
Yakakodzera ergonomics
A comfortable welding operator ndiyo yakachengeteka. Ergonomics yakakodzera inofanira kunge iri pakati pezvakakosha kutanga muMIG maitiro (pamwe chete nemidziyo yekudzivirira yemunhu, hongu).
A comfortable welding operator ndiyo yakachengeteka. Ergonomics yakakodzera inofanira kunge iri pakati pekutanga kutanga muMIG welding process (pamwe chete nemidziyo yekudzivirira yemunhu, hongu). Ergonomics inogona kutsanangurwa, zviri nyore, se "chidzidzo chekuti midziyo inogona kurongeka sei kuti vanhu vagone kuita basa kana zvimwe zviitiko zvakanyatsonaka uye zvakanaka."1 Kukosha kweergonomics kune welding operator kunogona kuva nemhedzisiro inosvika kure. Nzvimbo yebasa kana basa rinoita kuti mushandisi we welding adzokorore kusvika, kufamba, kubata kana kumonyoroka nenzira isiri yechisikigo, uye kunyange kugara muchimiro chakamira kwenguva yakareba pasina kuzorora. Zvese zvinogona kutungamira mukudzokororwa kushushikana kunetseka nemhedzisiro yehupenyu hwese.
Yakakodzera ergonomics inogona kuchengetedza vanogadzira welding kubva mukukuvadzwa uku ichivandudza chibereko uye pundutso yekushanda kwewelding nekuderedza kusavapo kwevashandi.
Dzimwe ergonomic mhinduro dzinogona kuvandudza kuchengetedzeka uye kubudirira dzinosanganisira:
1. Kushandisa MIG welding pfuti ine chigadziro chekuvhara kudzivirira "trigger finger". Izvi zvinokonzerwa nekushandisa kumanikidza kune trigger kwenguva yakareba.
2. Kushandisa pfuti yeMIG ine mutsipa unotenderera kuti ubatsire welding operator kuti afambe nyore nyore kuti asvike pajoini nekunetseka kuduku pamuviri.
3. Kuchengeta maoko paurefu hwegokora kana kuti pazasi zvishoma paunenge uchiwelding.
4. Kuisa basa pakati pechiuno cheanopisa welding nemapfudzi kuti ave nechokwadi chekuti welding iri kupedzwa mukati mepedyo nekusarerekera kwazvinoita.
5. Kuderedza kushushikana kwekudzokorora mafambiro nekushandisa MIG pfuti ine kumashure swivels patambo yemagetsi.
6. Kushandisa misanganiswa yakasiyana-siyana yemakona emubato, makona emutsipa uye urefu hwemutsipa kuchengetedza wrist yewelding welding munzvimbo isina kwayakarerekera.
Kona yebasa yakakodzera, kona yekufamba uye kufamba
Iyo yakafanira welding pfuti kana kona yebasa, kona yekufamba uye MIG welding tekinoroji zvinoenderana nehupamhi hwesimbi yepasi uye chinzvimbo chewelding. Basa rekona ndiro "hukama pakati peaxis ye electrode kune welders workpiece". Makona ekufamba (Trave angle) zvinoreva kushandisa kungave kona yekusundidzira (inongedza munzira yekufamba) kana kona yekukweva, apo electrode yakanongedzwa zvakapesana nekufamba.

Flat position
Paunenge uchipinza chidimbu chebutt (180-degree joint), welding operator anofanira kubata MIG welding gun pa90-degree work angle (maererano nebasa rekushanda). Zvichienderana nehupamhi hwezvinhu zvepasi, shandisa pfuti pakona yetochi pakati pe5 ne15 degrees. Kana iyo yakabatanidzwa ichida kudarika kwakawanda, zvishoma-kurutivi-kurutivi kufamba, kubata pazvigunwe zve weld, inogona kubatsira kuzadza chibatanidza uye kuderedza njodzi ye undercutting.
PamaT-joints, bata pfuti pakona yebasa ye45 degrees uye pamakumbo ejoint angle yebasa yakatenderedza 60 degrees yakakodzera (15 degrees kumusoro kubva 45 degrees).
Horizontal position
Munzvimbo yakatsetseka yewelding, kona yebasa ye30 kusvika ku60 degrees inoshanda zvakanaka, zvichienderana nerudzi uye ukuru hwejoini. Chinangwa ndechekudzivirira simbi yekuzadza simbi kuti isarembera kana kukunguruka nechepazasi pejoint yeweld.
Vertical position
Kubva pakushandisa yakachengeteka ergonomics kusvika pakushandisa iyo yakakodzera MIG pfuti angle uye welding mafambiro ekufambisa uye nezvimwe, maitiro akanaka eMIG anopa mhedzisiro yakanaka.
Kune T-joint, welding opareta anofanirwa kushandisa kona yebasa inopfuura 90 madhigirii kujoinhi. Cherechedza, kana welding munzvimbo yakatwasuka, pane nzira mbiri: weld mukwidza kana kudzika nzira.
Iyo nzira yekukwira inoshandiswa kune yakakora zvinhu kana kupinza kwakanyanya kunodiwa. Nzira yakanaka yeT-Joint inodana kumusoro-pasi V. Iyi nzira inovimbisa welding operator inochengetedza kuwirirana uye kupinda mukati memudzi we weld, iyo iyo zvidimbu zviviri zvinosangana. Iyi nzvimbo ndiyo inonyanya kukosha ye weld.Imwe hunyanzvi ndeyekudzika kwewelding. Izvi zvakakurumbira muindasitiri yepombi yekuvhurika midzi welding uye kana welding dzakatetepa geji zvinhu.
Overhead chinzvimbo
Chinangwa kana MIG welding pamusoro ndechekuchengeta yakanyungudutswa weld simbi mujoini. Izvo zvinoda kukurumidza kumhanya kwekufamba uye makona ebasa anozotemwa nenzvimbo yejoint. Chengetedza 5 kusvika ku15 madhigirii ekufamba. Chero unyanzvi hwekuruka hunofanira kuitwa hushoma kuti bhiza rive diki. Kuti uwane budiriro yakanyanya, welding opareta anofanirwa kunge ari munzvimbo yakagadzikana zvine chekuita nekona yebasa uye gwara rekufamba.
Wire stickout uye kuonana-tip-to-basa kure
Wire stickout ichachinja zvichienderana newelding process. Kukuchidzira-kupfupi-sekiti welding, zvakanaka kuchengetedza 1/4- kusvika 3/8-inch waya yekunamira kuti uderedze spatter. Chero nguva yakareba yekunamatira ichawedzera kusagadzikana kwemagetsi, kuderedza ikozvino uye kutungamirira kune spatter. Paunenge uchishandisa spray arc transfer, iyo stickout inofanira kunge yakatenderedza 3/4 inch.
Yakakodzera yekubata-tip-to-basa kure (CTWD) yakakoshawo kuti uwane yakanaka welding performance. Iyo CTWD inoshandiswa inotsamira pane welding process. Semuenzaniso, kana uchishandisa spray transfer mode, kana CTWD ipfupi, inogona kukonzera kupisa. Kana yakarebesa, inogona kukonzera weld discontinuities nekuda kwekushaikwa kwekudzivirira kwakaringana gasi kufukidzwa. Nekupfapfaidza kutamisa welding, 3/4-inch CTWD yakakodzera, nepo 3/8 kusvika 1/2 inch ingashanda kupfupi wedunhu welding.
Welding kufamba kumhanya
Kumhanya kwekufamba kunokanganisa chimiro uye kunaka kweweld bead kusvika padanho rakakura. Welding vanoshanda vachada kuona kwakaringana welding yekufamba kumhanya nekutonga weld dziva saizi zvine chekuita nekukora kwemajoini.
Nekumhanyisa kwekufamba kwewelding kunomhanya zvakanyanya, vagadziri vewelding vanozopedzisira vaine bhero nhete, ine convex isina kukwana kusungirira pazvigunwe zveweld. Kusakwana kwekupinda, kukanganisa uye kusingawirirani weld bead kunokonzerwa nekufamba nekukurumidza. Kufamba zvishoma nezvishoma kunogona kuunza kupisa kwakawandisa mukati meweld, zvichikonzera kuwanda kweweld bead. Pazvinhu zvitete, zvinogona kukonzera kupisa.
Pfungwa dzekupedzisira
Kana zvasvika pakuvandudza kuchengetedzeka uye kugadzira, zviri kune ane ruzivo veteran welding opareta senge iyo nyowani welding yekumisikidza uye kutevedzera chaiyo MIG nzira chaiyo. Kuita izvi kunobatsira kudzivirira kukuvara kunogona kuitika uye nguva isingakodzeri yekudzikira yekugadzirazve hurombo husina kunaka welds. Ramba uchifunga kuti hazvimborwadze kune vanogadzira welding kuti vazorodze ruzivo rwavo nezveMIG welding uye zviri mune yavo uye nekambani kufarira kwavo kuramba vachitevera maitiro akanaka.
