Momwe Mungasinthire Ma Parameters mu CO2 Welding

Kusintha magawo ndondomeko kwa mpweya woipa wotetezedwa kuwotcherera: Pali magawo ambiri ndondomeko zimene zimakhudza mpweya woipa wotetezedwa kuwotcherera, koma okhawo welders akhoza kusintha okha ndi kuwotcherera voteji, kuwotcherera panopa, waya awiri, mpweya otaya mlingo, ndi kukulitsa waya. kutalika; Mfundo mfundo zowotcherera ndondomeko magawo: The ambiri ntchito waya diameters ndi 1.2mm ndi 1.0mm, kuwonjezera 1.6mm ndi 0.8mm. Ndizovuta kukumana ndi mawaya owotcherera a ma diameter ena. Mpweya wotetezedwa ndi mpweya wotsekemera wa carbon dioxide umagwiritsa ntchito kusintha kwafupipafupi, kotero kuti malo opangira mawotchi amtundu uliwonse wa waya wowotcherera ndi waukulu. M'derali, mphamvu zowotcherera pano ndi zowotcherera ziyenera kufananizidwa.

Njira yogwiritsira ntchito makina opangira kuwotcherera: Sinthani mawotchi amakono ndi magetsi a makina otsekemera malinga ndi ndondomekoyi;

1. Tsegulani valavu yoteteza gasi ya silinda ndikutsimikizira kuti kuthamanga kwa silinda ya gasi ndikoyenera; Yatsani mphamvu yamakina akuwotcherera ndikutsimikizira kuti kutentha ndi kuchepetsa kuthamanga kwa flowmeter kukugwira ntchito; Kutentha kwa mphindi 5;
2. Tsegulani zoikamo za waya wowotcherera, ikani chowotcherera cha waya wowotcherera pa shaft ya waya wodyera, tsegulani chogwiriracho, ndikugwiritsa ntchito pliers kudula mutu wa waya wowotcherera mumutu wathyathyathya. Waya wowotcherera mutu uyenera kulowetsedwa mopingasa mu gudumu la poyambira la wodzigudubuza mawaya kuchokera pansi pa chowotcherera waya; Ikani waya wodyetsa payipi;
3. Tsekani chogwirira cha clamping, ikani mfuti yowotcherera pansi ndikuyikulitsa. Dinani batani loyatsira mawaya achangu pabokosi lowongolera kuti mudyetse waya wowotcherera mpaka itawonekera kuchokera pamphuno ya conductive. Ngati ndi mfuti yakale yowotcherera, mutha kuchotsa kaye mphuno ya conductive, kenako dinani chosinthira chaching'ono kuti mudyetse waya, kuwulula, ndikuyiyikanso; Gwiritsani ntchito pliers kudula mapeto a waya wowotcherera mu ngodya yakuthwa ya madigiri 45;

4.Konzani mbale yachitsulo yoyesera, fufuzani voltmeter ndi ammeter ya makina otsekemera, tsitsani mwachidwi mphamvu pa bokosi lakutali ndi dzanja lanu lamanzere, gwirani mfuti yowotcherera ndi dzanja lanu lamanja, ndikuyambitsa kuwotcherera kwa arc pazitsulo zoyesera. mbale; Ngati votejiyo ilidi yotsika, dzanja lamanja lomwe likugwira mfutiyo lidzamva kugwedezeka kwamphamvu kwa mutu wa mfuti yowotcherera ndikumva phokoso la arc. Izi ndizomwe zimamveka pamene voteji imakhala yochepa kwambiri, liwiro la kudyetsa waya ndilothamanga kwambiri kuposa liwiro losungunuka, ndipo arc imayatsidwa ndikuzimitsidwa ndi waya wowotcherera; Ngati magetsi ali okwera kwambiri, arc imatha kuyaka, koma ngati kutalika kwa arc kuli kotalika, mpira waukulu wosungunuka umapanga kumapeto kwa waya wowotcherera. Ngati liwiro losungunuka liposa liwiro la kudyetsa waya kwambiri, arc idzapitirizabe kuwotcha kumbuyo kwa phokoso la conductive, kusungunula waya wotsekemera ndi phokoso la conductive pamodzi, kuthetsa kudyetsa waya, ndi kuzimitsa arc. Izi zidzachititsa kuwonongeka kwa phokoso la conductive komanso njira yodyetsera waya, choncho ziyenera kutsimikiziridwa kuti magetsi sali okwera kwambiri poyambitsa arc;

5. Sinthani kuwotcherera voteji mfundo, pang'onopang'ono kuwonjezera kuwotcherera voteji, imathandizira kusungunuka liwiro la kuwotcherera waya, ndi akulimbana phokoso la breakage pang'onopang'ono kukhala yosalala rustling phokoso;
6. Onani voltmeter ndi ammeter. Ngati panopa ndi wotsika kuposa mtengo anakonzeratu, kuwonjezera kuwotcherera panopa choyamba ndiyeno kuwonjezera voteji kuwotcherera; Ngati panopa ndi apamwamba kuposa mtengo anakonzeratu, choyamba kuchepetsa kuwotcherera voteji, ndiyeno kuchepetsa kuwotcherera panopa;
7. Kutalika kwa waya wowotcherera: womwe umatchedwanso kutalika kwa waya wowotcherera. Kwa kuwotcherera kotetezedwa ndi gasi, ndikofunikira kwambiri. Kutalika koyenera kwa waya wowotcherera kungapereke kutentha kokwanira kukana, kuti zikhale zosavuta kupanga ndi kusintha madontho osungunuka kumapeto kwa waya wowotcherera. Pamene kutalika kwa waya wowotcherera kuli kochepa kwambiri, nthawi zambiri pamakhala kuphulika kwakukulu. Kukhala motalika kwambiri sikumangotulutsa madontho akulu, komanso kumabweretsa chitetezo chochepa.
8. Chodabwitsa pamene kuwotcherera voteji ndi kuwotcherera panopa zikufanana: arc amayaka pang'onopang'ono, kupanga phokoso lomveka bwino, kuwotcherera mfuti mutu kunjenjemera pang'ono, kuuma ndi zolimbitsa, voltmeter kugwedezeka si upambana 5V, kugwedezeka kwa ammeter sikudutsa 30A, ndi pasakhale kugwedezeka pa dzanja; Ngati mutu wa mfuti yowotcherera umakhala wofewa kwambiri ndipo palibe kugwedezeka kulikonse, mfuti yowotcherera imatha kusuntha momasuka. Kupyolera mu kuyang'ana kwa chigoba kumaso, waya wowotcherera amayandama pamwamba pa dziwe losungunuka, kupanga mpira waukulu wosungunuka kumapeto, ndipo nthawi zina madontho akuluakulu amawombera, kusonyeza kuti magetsi ndi okwera kwambiri; Ngati mutu wa mfuti yowotcherera ukumva molimba ndikugwedezeka kwambiri, phokoso la phokoso limamveka, ndipo pali kukana pamene mukusuntha mfuti yowotcherera. Kupyolera mu kuyang'ana kwa chigoba cha nkhope, ngati waya wowotcherera walowetsedwa mu dziwe losungunuka ndikuphwanya kwambiri, zimasonyeza kuti magetsi ndi otsika; Ndikopindulitsa kukhala ndi magetsi okwera pang'ono kuti mupewe kusakanikirana kosakwanira.
9. Kuwotcherera mpweya wotetezedwa ndi elekitirodi yosungunuka, kusintha kwa kuwotcherera pakali pano ndikusintha liwiro la waya wodyera wa waya wowotcherera, komanso kusintha kwa voteji ndikusintha liwiro losungunuka la waya wowotcherera. Pamene liwiro la kudyetsa waya ndi liwiro losungunuka ndilofanana, arc imayaka mokhazikika.
