Welding Techniques dzeMIG Welding

Chengetedza welding wire rod yekuwedzera ye 1/4 kusvika 3/8 inches (kureba kwewaya yewelding inobuda kubva mumusoro wepfuti).
Shandisa diki dhayamita welding waya paunenge uchipinza mahwendefa matete; Pakusecha mahwendefa akakora, waya dzakakura dzedhayamita dzewelding uye michina yekukwesha yakakwira ikozvino inoshandiswa.
Shandisa iyo chaiyo welding waya kuti weld workpiece. Stainless simbi welding wire welding Stainless simbi, aluminum welding wire welding aluminium, simbi welding wire welding simbi.
Shandisa gasi rekudzivirira rakakodzera. Carbon dioxide yakanyatsokodzera kune welding simbi, asi kana ikashandiswa kupinza mahwendefa matete, tembiricha inogona kunge yakanyanya kukwirisa. Musanganiswa we75% argon gasi uye 25% carbon dioxide gasi inofanira kushandiswa kupinza zvinhu zvitete. Welding aluminium inogona chete kushandisa argon gasi. Paunenge uchipinza simbi, unogona zvakare kushandisa musanganiswa wemagasi matatu (helium+argon+carbon dioxide).
Kuti uwane kudzora kwakanakisa kwe weld bead, iyo welding wire inofanirwa kuchengetwa yakanangana yakanangana neiyo yekubatanidza kumucheto kwechidziva chekunyungudika.
Kana iyo welding operation iri munzvimbo isina kujairika (vertical welding, horizontal welding, overhead welding), dziva diki rakanyungudutswa rinofanira kuchengetedzwa kuti riwane kutonga kwakaringana kweweld bead, uye diki dhayamita welding waya inofanira kushandiswa zvakanyanya sezvinobvira.
Ita shuwa kuti saizi yewaya yewelding yauri kushandisa inofanana nemuromo, liner, uye drive roller.
Gara uchichenesa iyo welding pfuti liner uye kutyaira rollers kuti uone kuti hapana spatter pamuromo wepfuti yemoto. Kana muromo wepfuti yakavharwa kana kuti waya yekudyisa isina kutsvedzerera, itsive.
Munguva yewelding, edza kuchengeta pfuti yekubatira yakatwasuka kuti udzivise nyaya dzekudyisa waya.
Shandisa maoko ese ari maviri panguva imwe chete panguva yekushanda kwewelding kuti uve nechokwadi chekugadzikana kwepfuti yewelding, uye ita saizvozvo nepaunogona napo. (Izvi zvinoshandawo kune electrode welding, TIG welding, uye plasma yekucheka)
Gadzirisa kusimba kwewaya yewelding spool uye dhiraivha yewaya yekudyisa kuti ingori yakaringana kudyisa waya, pasina kusimba zvakanyanya.
Kana isiri kushandiswa, chengetedza waya welding munzvimbo yakachena uye yakaoma kudzivirira kusvibiswa kunogona kukanganisa mhedzisiro yewelding.
Shandisa DC reverse polarity DCEP magetsi.
Iyo yekudhonza (kudhonza) welding pfuti tekinoroji inogona kuwana yakadzika kupinda uye yakamanikana welds. Iyo pfuti yekusundidzira tekinoroji inogona kuwana kudzika kupinza uye yakakura weld seams.
