Iimbangela zokubunjwa kwe-undercut enye enamacala amabiniumbhobho wentsimbi odityanisiweyo we-arc

I-Welding wire joint

Ngenxa yotshintsho kwidayamitha kunye nokuguda komdibaniso wocingo, isantya sokutya kocingo siya kutshintsha ngesiquphe xa umdibaniso wocingo udlula kwivili lokutya kocingo, ngaloo ndlela kubangele utshintsho olukhawulezileyo kumbane we-welding kunye nesantya sokunyibilika, ukwanda ngequbuliso kwe-weld. ichibi kunye nesinyithi esinyibilikisiweyo Ukungonelanga kongezelelo kunokubangela i-undercut enye ephindwe kabini kule solder joint.

Ukucaciswa kwe-welding

Kwiimeko eziqhelekileyo, akuyi kubakho utshintsho olukhulu kwiinkcazo ze-welding ngexesha lokuvelisa okuqhubekayo.Ngoko ke, ii-undercuts aziyi kwenzeka ngexesha lemveliso eqhelekileyo.Nangona kunjalo, phantsi kwefuthe lonikezelo lwamandla lwangaphandle, i-welding current kunye ne-voltage inokuthi iqhube ngokukhawuleza, kwaye umphumo wokutshintsha ngokukhawuleza uya kukhokelela ekugqibeleni kwi-undercuts.

Isiphaluka esifutshane esikhawulezileyo

Ngamanye amaxesha ngenxa ye-burr emaphethelweni ebhodi okanye i-metal burr exutywe kwi-flux, isiphaluka esifutshane ngokukhawuleza siya kwenzeka kwi-tip yoqhagamshelwano ngexesha lenkqubo ye-welding eqhelekileyo.Isiphaluka esifutshane ngokukhawuleza siya kubangela ukuba i-welding current kunye ne-voltage itshintshe ngokukhawuleza, ekugqibeleni iya kukhokelela kwi-undercut.Ukunyangwa kwe-undercut eyodwa ephindwe kabini kuyafana nendlela yonyango ye-undercut enye, enokuthi iqhutywe ngokugaya okanye ukulungiswa.
