MIG welding, senge chero imwe maitiro, inotora kudzidzira kunatsiridza hunyanzvi hwako. Kune avo vatsva kwairi, kuvaka rumwe ruzivo rwekutanga kunogona kutora yako MIG welding oparesheni kune inotevera nhanho. Kana kuti kana wanga wave welding kwekanguva, hazvimbokuvadzi kuva nerefresher. Funga nezve iyi mibvunzo inowanzo bvunzwa, pamwe nemhinduro dzadzo, sematipi ekukugidzira ekukutungamira.
1. Ndeipi dhiraivha roll yandinofanira kushandisa, uye ndinoisa sei tension?
Iyo welding waya saizi uye mhando inosarudza drive roll kuti iwane yakatsetseka, inopindirana waya yekudyisa. Pane zvitatu zvakajairika sarudzo: V-knurled, U-groove uye V-groove.
Pair gasi- kana self-shield waya dzine V-knurled drive rolls. Waya dzewelding idzi dzakapfava nekuda kwekugadzirwa kwayo tubular; mazino ari padhiraivha anotapudza waya uye oisundira kuburikidza nedhiraivha. Shandisa U-groove drive rolls yekudyisa aluminium welding waya. Chimiro chemadhiraivha aya chinodzivirira kuparara kwewaya iyi yakapfava. V-groove drive rolls ndiyo yakanakisa sarudzo kune yakasimba waya.
Kuseta tension yedhiraivha, tanga waburitsa madhiraivha. Zvishoma nezvishoma wedzera tension paunenge uchidyisa waya muruoko rwako rwegirovhosi. Ramba kusvikira tension yave imwe half-turn past wire slippage. Munguva yekuita, chengetedza pfuti yakatwasuka sezvinobvira kudzivirira kinking tambo, izvo zvinogona kutungamirira kune hurombo hwekudya.
Kutevera mamwe makiyi akanakisa maitiro ane chekuita newelding waya, drive rolls uye kudzivirira gasi zvinogona kubatsira kuve nemhedzisiro yakanaka muMIG welding process.
2. Ndinowana sei mibairo yakanaka kubva kune yangu MIG welding waya?
MIG welding waya dzinosiyana muhunhu hwavo uye welding paramita. Gara uchitarisa iyo waya yakatarwa kana data sheet kuti uone kuti amperage, voltage uye waya yekudyisa kumhanya inokurudzirwa nemugadziri wesimbi. Mashiti chaiwo anowanzo kutumirwa newaya yewelding, kana iwe unogona kuadhawunirodha kubva kune yekuzadza simbi webhusaiti webhusaiti. Aya mapepa anopawo kudzivirira gasi zvinodiwa, pamwe nekusangana-kune-basa kure (CTWD) uye welding waya yekuwedzera kana stickout kurudziro.
Stickout inonyanya kukosha kuti uwane mhedzisiro yakanaka. Kurebesa kwekunamira kunoita kutonhora kunopisa, kunodonhedza amperage uye kunoderedza kupinda kwemajoini. Chinamira chipfupi chinowanzopa arc yakagadzikana uye nani yakaderera-voltage kupinda. Sekutonga kwechigunwe, iyo yakanakisa yekunamatira kureba ndiyo ipfupi inotenderwa kunyorera.
Yakafanira welding waya kuchengetedza uye kubata kwakakosha kune yakanaka MIG welding mhinduro. Chengetedza spool munzvimbo yakaoma, sezvo hunyoro hunogona kukuvadza waya uye hunogona kutungamirira kune hydrogen-induced cracking. Shandisa magirovhosi paunenge uchibata waya kuti uidzivirire kubva kuhunyoro kana tsvina kubva mumaoko ako. Kana waya iri pawaya yekudyisa, asi isiri kushandiswa, vhara spool kana kuibvisa woiisa mubhegi repurasitiki rakachena.
3. Ndeipi yekubata recess yandinofanira kushandisa?
Bata tip recess, kana chinzvimbo chetipi yekubata mukati meMIG welding nozzle, zvinoenderana newelding mode, welding waya, application uye kudzivirira gasi rauri kushandisa. Kazhinji, sezvo ikozvino inowedzera, iyo yekubata tip recess inofanirawo kuwedzera. Heano mamwe mazano.
A 1/8- kana 1/4-inch recess inoshanda zvakanaka pakugadzira maamps anopfuura mazana maviri muspray kana high-current pulse welding, paunenge uchishandisa simbi-cored wire uye argon-rich shielding magasi. Iwe unogona kushandisa waya stickout ye 1/2 kusvika 3/4 inches mune izvi zviitiko.
Chengetedza kutitipi yako yekubata inonyunguduka nemuromo kana welding isingasviki mazana maviri amps mupfupi wedunhu kana yakaderera-ikozvino pulse modes. A 1/4- kusvika 1/2-inch waya stickout inokurudzirwa. Pa 1/4-inch stick out in short circuit, kunyanya, inokubvumira kuti uite weld pazvinhu zvitete zvine ngozi shoma yekutsva-kuburikidza kana kurwisana.
Kana welding zvakaoma-kusvika-kusvika majoini uye ari pasi pe200 amps, unogona kuwedzera yekubata tip 1/8 inch kubva pamuromo uye kushandisa 1/4-inch stickout. Iyi gadziriso inobvumira kupinda kukuru kune yakaoma-ku-kuwana majoini, uye inoshanda zvakanaka kune pfupi dunhu kana yakaderera-ikozvino pulse modes.
Rangarira, kuzorora kwakakodzera ndiko kudzikisa mukana weporosity, kusakwana kwekupinda uye kupisa-kuburikidza uye kuderedza spatter.
Iyo yakakodzera yekubata tip recess chinzvimbo inosiyana zvichienderana nekushandisa. Mutemo wakawanda: Sezvo ikozvino inowedzera, iyo recess inofanirawo kuwedzera.
4. Ndeipi gasi rekudzivirira rakanakira waya yangu yeMIG welding?
Iyo yekudzivirira gasi yaunosarudza zvinoenderana newaya uye mashandisirwo. CO2 inopa kupindira kwakanaka kana welding zvinhu zvakakora, uye unogona kuishandisa pazvinhu zvitete nekuti zvinogara zvichitonhorera, izvo zvinoderedza njodzi yekutsva-kuburikidza. Kuti uwedzere kupinda mukati uye kubereka kwakanyanya, shandisa 75 muzana argon / 25 muzana CO2 gasi musanganiswa. Musanganiswa uyu unoburitsawo spatter shoma pane CO2 saka pane kushoma post-weld kuchenesa.
Shandisa 100 muzana CO2 yekudzivirira gasi kana 75 muzana CO2/25 muzana argon musanganiswa pamwe chete nekabhoni simbi yakasimba waya. Aluminium welding wire inoda argon shielding gasi, nepo Stainless simbi waya inoshanda zvakanyanya netri-mix yehelium, argon uye CO2. Gara uchinongedzera waya's spec sheet kune zvinokurudzirwa.
5. Ndeipi nzira yakanakisa yekudzora dhiri rangu re weld?
Pazvinzvimbo zvese, zvakanakisa kuchengetedza waya welding yakananga kumucheto unotungamira we weld puddle. Kana iwe uri welding kubva panzvimbo (yakatwasuka, yakachinjika kana pamusoro), kuchengeta weld puddle idiki kunopa yakanakisa kutonga. Uyezve shandisa dhayamita diki yewaya iyo icharamba ichizadza weld joint zvakakwana.
Iwe unogona kuyera kupisa kwekuisa uye kumhanya kwekufamba neiyo weld bead inogadzirwa uye kugadzirisa zvinoenderana kuti uwane kutonga kuri nani uye zvirinani mhedzisiro. Semuenzaniso, kana iwe ukagadzira weld bead iyo yakareba uye yakapfava, inoratidza kuti kupisa kwekuisa kwakadzikira uye / kana kukurumidza kwako kwekufamba kunokurumidza. Bhero rakati sandara, rakafara rinoratidza kupisa kwakanyanya uye/kana kunonoka kwekumhanya kwekufamba. Rongedza maparamita ako uye hunyanzvi zvinoenderana kuti uwane iyo yakanakira weld, ine kakorona kadiki inongobata simbi yakaitenderedza.
Iyi mhinduro kumibvunzo inowanzo bvunzwa inongobata pane mashoma eakanakisa maitiro eMIG welding. Gara uchitevera yako welding maitiro kuti uwane mibairo yakakwana. Zvakare, akawanda emagetsi emagetsi uye vagadziri vewaya vane nhamba dzekutsigira tekinoroji kubata nemibvunzo. Vanogona kushanda sechinhu chakanakisa chekushandisa kwauri.
