Amaxesha aphakathioomatshini bokuwelda amabalazifuna i-electrodes ukugqiba inkqubo ye-welding. Umgangatho we-electrodes uchaphazela ngokuthe ngqo umgangatho wee-welds. Ii-electrodes zisetyenziselwa ukuhambisa okwangoku kunye noxinzelelo kwi-workpiece. Nangona kunjalo, ukusebenzisa izinto ezingaphantsi kwe-electrode kunokukhawulezisa ukunxiba ngexesha lokusetyenziswa, okukhokelela ekwandeni kwexesha lokusila kunye nokumoshakala kwezinto ezikrwada. Ngoko ke, kubalulekile ukukhetha i-electrodes ngokusekelwe kwizinto ezidityanisiweyo.
I-Electrodes kufuneka ibe nenqanaba elithile lobunzima bobushushu obuphezulu, ngakumbi ukugcina obu bunzima kumaqondo obushushu aphakathi kwe-5000-6000 ° C. Ubulukhuni obuphezulu bobushushu obuphezulu buthintela ukupakishwa kwe-electrode ngexesha lenkqubo ye-welding. Ngokuqhelekileyo, iqondo lokushisa kwindawo yokudibanisa phakathi kwe-workpiece kunye ne-electrode ngexesha le-welding li malunga nesiqingatha sendawo yokunyibilika kwentsimbi edibeneyo. Ukuba izinto ze-electrode zinobunzima obuphezulu kumaqondo aphezulu kodwa ubunzima obuphantsi ngexesha le-welding, ukupakishwa kusengenzeka.
Isiphelo sokusebenza se-electrode siza kwiimilo ezintathu: i-cylindrical, i-conical, kunye ne-spherical. Iimilo ezi-Conical kunye ne-spherical zisetyenziswa kakhulu kuba ziphucula ukupholisa kunye nokunciphisa ubushushu be-electrode. Nangona i-electrodes engqukuva inobomi obude, ukutshatyalaliswa kobushushu okukhawulezayo, kunye nenkangeleko engcono ye-weld, ukuveliswa kunye nokulungisa ngakumbi kunokuba ngumngeni. Ke ngoko, i-conical electrode ikhethwa ngokubanzi.
Ukukhethwa kwendawo yokusebenza kuxhomekeke kuxinzelelo olusetyenzisiweyo. Indawo enkulu yokusebenza iyadingeka xa uxinzelelo luphezulu ukukhusela umonakalo ekupheleni kwe-electrode. Ngoko ke, njengoko ubukhulu beplate bukhula, ububanzi bomsebenzi osebenzayo kufuneka bunyuke. Umphezulu wokusebenza ngokuthe ngcembe unxiba kwaye uyanda ngexesha lokusebenza. Ke ngoko, ukulungiswa kwangexesha kuyafuneka ngexesha lemveliso ye-welding ukunqanda ukuhla koxinaniso lwangoku olukhokelela ekunciphiseni ukungena kwe-fusion okanye kungabikho nucleus yokudibanisa. Ukwamkela indlela apho i-current inyuka ngokuzenzekelayo ngokunyuka kwenani le-welds inokwandisa ixesha phakathi kokulungiswa ezimbini.
UziSombulula njani iimpazamo ezincinci koomatshini bokuwelda bamaxesha aPhakathi?
Isixhobo asinamandla: ukungaqhelekanga kumatshini we-thyristor, impazamo kwibhokisi yokulawula i-P ibhodi.
Isixhobo asisebenzi emva kokusebenza: uxinzelelo lwegesi olungonelanga, ukungabikho komoya ocinezelweyo, i-valve ye-solenoid engaqhelekanga, ukutshintshwa kokusebenza okungaqhelekanga, okanye umlawuli ongasetyenziswanga, ukusebenza kwe-relay yokushisa.
Iintanda zivela kwi-welds: i-oxidation layer over over the workpiece surface, i-welding current ephezulu, uxinzelelo lwe-electrode ephantsi, iziphene kwintsimbi edibeneyo, ukungahambi kakuhle kwe-electrode ephantsi, ukulungiswa kwezixhobo ezingachanekanga.
Amandla angonelanga amanqaku e-weld: uxinzelelo lwe-electrode olunganelanga, nokuba intonga ye-electrode ikhuselwe ngokuqinileyo.
Ukutshiza okugqithisileyo ngexesha le-welding: i-oxidation enzima yentloko ye-electrode, uqhagamshelwano olubi lweendawo ezidibeneyo, nokuba ukutshintshwa kohlengahlengiso kubekwe phezulu kakhulu.
Ingxolo enkulu evela kwi-welding AC contactor: ingaba i-voltage engenayo ye-AC contactor ngexesha le-welding ingaphantsi kune-voltage yayo yokukhululwa ngama-300 volts.
Izixhobo zigqithisa kakhulu: jonga uxinzelelo lokungena kwamanzi, izinga lokuhamba kwamanzi, ukubonelela ngobushushu bamanzi, nokuba ukupholisa kwamanzi kuvaliwe.: leo@agerawelder.com
