Mfundo yogwirira ntchito:
The kuwotcherera nyali ntchito kutentha kwaiye ndi mkulu panopa ndi mkulu voteji panopa kusonkhanitsa pa mapeto a kuwotcherera nyali, ndi waya wosungunuka amalowa mu gawo kuti welded.Pambuyo kuzirala, chinthu chowotchereracho chimalumikizidwa mwamphamvu kukhala chimodzi.
Mphamvu ya nyali imadalira mphamvu ya welder ndi zinthu zowotcherera.
Kuwotcherera tochi kuwotcherera zotsatira oyenerera, kuwotcherera chitetezo, kudya liwiro.
Tochi yowotcherera imakhala ndi magwiridwe antchito odalirika, kukonza kosavuta komanso kusintha kosavuta.
Kuwotcherera mfuti sagwiritsa ntchito magetsi, kupulumutsa chitsulo, zida ndalama ndi yaing'ono ndi ubwino zina.
Kugwiritsa ntchito tochi yowotcherera:
Pamene tikufuna kuwotcherera, choyamba tiyenera kusankha yoyenera chitsanzo ndi osiyana caliber kuwotcherera nozzle malinga ndi kukula, makulidwe ndi matenthedwe matenthedwe matenthedwe osiyana.Opaleshoni, choyamba masulani acetylene lophimba, ndiyeno pang'ono unscrew lophimba mpweya, anayatsa acetylene chipika, ndiye kutentha lawi si mkulu, nozzle amapereka zigawo ziwiri za woyera lawi pachimake, kuwonjezera, chifukwa acetylene kwambiri kuyaka si wathunthu, nthawi zambiri utsi wakuda, kuwala pang'ono patsogolo zotsatira zina za okosijeni ndi kuchepetsa utsi wakuda.Kuti kuwotcherera, kusintha mpweya lophimba, kuti mpweya ndi acetylene mpweya zoyenera, kuyaka okwanira, kutentha.Pamene kuwotcherera, cholumikizira chowotchereracho chimayamba kuwotchedwa mpaka kutentha kofiyira, ndiyeno ndodo yowotcherera imatenthedwa pa weld ndikudzazidwa ndi olowa.Pambuyo kusungunuka pamodzi, lawi la oxyacetylene likhoza kuchotsedwa, ndipo kuwotcherera kumatsirizidwa ndi kuzizira.
Kusankhidwa kwa electrode:
Kaya kuwotcherera kapena kukonza, ndikofunikira kusankha electrode yoyenera ngati chitsulo chodzaza.Mphamvu ndi ntchito ya olowa si zogwirizana ndi kuwotcherera ndondomeko, komanso mwachindunji zinthu za elekitirodi timagwiritsa ntchito.
Nthawi zambiri, kusungunuka kwa ndodo yowotcherera sikuyenera kukhala kokwera kuposa kusungunuka kwa mbali zowotcherera, apo ayi sikwabwino kudziwa bwino dziwe lachitsulo pakuwotcherera, kotero kuti kuwotcherera kumawonongeka.
