1. Isishwankathelo
Uluhlu lwe-welding luhlobo lokumelana ne-welding. Yindlela ye-welding apho i-workpieces idityaniswa ukuze yenze i-lap joint okanye i-butt joint, kwaye ibekwe phakathi kwee-electrode ezimbini ze-roller. I-electrode ye-roller icinezela i-weldment kwaye ijikeleze, kwaye amandla ngokuqhubekayo okanye ngokuphindaphindiweyo asetyenziswe ukwenza i-weld eqhubekayo. I-Welding Roll isetyenziswa ngokubanzi ekwenzeni amajoyinti afuna ukutywinwa, kwaye ngamanye amaxesha isetyenziselwa ukudibanisa iinxalenye zentsimbi ezingatywinwanga. Ubukhulu bezinto zetsimbi ezidibeneyo zidla ngo-0.1-2.5 mm.
Imivumbo isetyenziswa kwiivalvu, ikakhulu ukutywina kunye nokwahlula. Kwiintlobo ezahlukeneyo zevalve, nokuba yivalve yokumisa, ivalve ye-throttle, ivalve elawulayo okanye ivalve yokunciphisa uxinzelelo, i-bellows isetyenziswa njengento yokupakisha ngaphandle kokutywina okukodwa kwesiqu sevalve. Ngethuba lokusebenza kwevalve, i-bellows kunye ne-valve stem zihanjiswa nge-axially kwaye zibuyiselwe kunye. Kwangaxeshanye, ikwamelana noxinzelelo lolwelo kwaye iqinisekisa ukutywinwa. Xa kuthelekiswa nokupakisha iivalve zokutywina, iivalve zebellows zinokuthembeka okuphezulu kunye nobomi benkonzo. Ke ngoko, iivalvu ze-bellows zisetyenziswe ngokubanzi kushishino lwenyukliya, i-petroleum, ishishini lemichiza, amayeza, i-aerospace, njl.njl. Kwizicelo ezisebenzayo, i-bellows isoloko idityaniswa kunye namanye amacandelo afana neeflange, imibhobho kunye neziqu zevalvu. Imivuno idityaniswe nge-welding roll, esebenza kakhulu kwaye isetyenziswa ngokubanzi.
Iivalvu zenyukliya zevacuum eziveliswe yinkampani yethu zisetyenziswa kwindawo ezingqongileyo zeuranium fluoride apho okuphakathi kunokutsha, uqhushumbo kunye neradioactive. Imibhobho yenziwe nge-1Cr18Ni9Ti enobunzima obuyi-0.12mm. Zidityaniswe kwidiski yevalve kunye nedlala ngokudibanisa i-roll. I-weld kufuneka ibe nokusebenza okuthembekileyo kokutywinwa phantsi koxinzelelo oluthile. Ukuze ukulungisa ingxaki kunye nokuguqula izixhobo esele zikho zokuwelda ukuhlangabezana neemfuno zemveliso, uyilo lwezixhobo kunye novavanyo lwenkqubo lwenziwa, kwaye iziphumo ezifanelekileyo zafunyanwa.
2. Izixhobo ze-welding roll
I-FR-170 capacitor yokugcina amandla umatshini we-welding roll isetyenzisiweyo, kunye nomthamo wokugcina amandla we-capacitor ye-340μF, uluhlu lohlengahlengiso lwe-voltage yokutshaja ye-600 ~ 1 000V, uluhlu lohlengahlengiso loxinzelelo lwe-electrode lwe-200 ~ 800N, kunye nokugcinwa okuphezulu kwe-170J. . Umatshini usebenzisa i-zero-evaliweyo yokubunjwa kwesekethe kwisekethe, esusa ubugwenxa bokuguquguquka kombane womnatha kwaye iqinisekise ukuba i-pulse frequency kunye ne-charge voltage ihlala izinzile.
3. Iingxaki ngenkqubo yokuqala
1. Inkqubo ye-welding engazinzanga. Ngethuba lenkqubo yokuguqa, umphezulu utshiza kakhulu, kwaye i-welding slag ibambelela ngokulula kwi-roller electrode, eyenza kube nzima kakhulu ukusebenzisa i-roller ngokuqhubekayo.
2. Ukusebenza kakubi. Ngenxa yokuba i-bellows i-elastic, i-weld ilula ukuphambuka ngaphandle kokubeka i-welding tooling ngokufanelekileyo, kwaye i-electrode kulula ukuyibamba kwezinye iindawo ze-bellows, ibangela iintlantsi kunye ne-splashes. Emva kweveki ye-welding, iziphelo ze-weld azihambelani, kwaye ukutywinwa kwe-weld akuhambelani neemfuno.
3. Umgangatho we-weld ongalunganga. I-weld point indentation inzulu kakhulu, umphezulu ushushu ngokugqithisileyo, kwaye nokutshisa okuncinci kuyenzeka. Umgangatho we-weld owenziweyo umpofu kwaye awukwazi ukuhlangabezana neemfuno zovavanyo loxinzelelo lwegesi.
4. Ukuthintelwa kweendleko zemveliso. Imibhobho yevalvu yenyukliya iyabiza. Ukuba ukutshisa kwenzeka, imivumbo iya kuchithwa, okonyusa iindleko zemveliso.
Izixhobo zokuwelda iXinfa zineempawu zomgangatho ophezulu kunye nexabiso eliphantsi. Ngeenkcukacha, nceda undwendwele:Abavelisi beWelding & Cutting-China Welding & Cutting Factory & Suppliers (xinfatools.com)
4. Uhlalutyo lweeparamitha eziphambili zenkqubo
1. Uxinzelelo lwe-electrode. Ukudibanisa i-welding, uxinzelelo olusetyenziswe yi-electrode kwi-workpiece yiparameter ebalulekileyo echaphazela umgangatho we-weld. Ukuba uxinzelelo lwe-electrode luphantsi kakhulu, luya kubangela ukutshiswa kwendawo yendawo, ukuphuphuma, ukutshiza komhlaba kunye nokungena ngokugqithiseleyo; ukuba uxinzelelo lwe-electrode luphezulu kakhulu, ukunyanzeliswa kuya kuba nzulu kakhulu, kwaye i-deformation kunye nokulahlekelwa kwe-electrode roller iya kukhawuleziswa.
2. Isantya se-welding kunye ne-pulse frequency. Kwi-weld roll etywiniweyo, i-denser amanqaku e-weld, ngcono. I-coefficient ye-overlap phakathi kwamanqaku e-weld ikhethwa ukuba yi-30%. Ukutshintsha kwesantya se-welding kunye ne-pulse frequency kuchaphazela ngokuthe ngqo utshintsho lwesantya sokugqitha.
3. Ukutshaja i-capacitor kunye ne-voltage. Ukutshintsha i-capacitor yokutshaja okanye i-voltage yokutshaja itshintsha amandla athunyelwe kwindawo yokusebenza ngexesha le-welding. Indlela ehambelanayo yeeparitha ezahlukeneyo zemibini inomahluko phakathi kweenkcukacha ezinamandla kunye nezibuthathaka, kunye neenkcukacha ezahlukeneyo zamandla ezifunekayo kwizinto ezahlukeneyo.
4. I-roller electrode isiphelo sefom yobuso kunye nobukhulu. Iifom ze-roller electrode ezisetyenziswa ngokuqhelekileyo luhlobo lwe-F, uhlobo lwe-SB, uhlobo lwe-PB kunye nohlobo lwe-R. Xa ubukhulu bobuso besiphelo se-electrode ye-roller ayifanelekanga, kuya kuchaphazela ubungakanani be-weld core kunye nesantya sokungena, kwaye kuya kuba nefuthe elithile kwinkqubo ye-welding.
Ekubeni iimfuno zomgangatho we-roll weld joints zibonakaliswa ngokukodwa ekutywinweni okulungileyo kunye nokuxhatshazwa kwe-corrosion of joints, impembelelo yokungena kunye nesantya sokugqithisa kufuneka siqwalaselwe xa simisela iiparitha ezingentla. Kwinkqubo ye-welding yangempela, iiparitha ezahlukeneyo zichaphazela omnye nomnye kwaye kufuneka zilungelelaniswe ngokufanelekileyo kwaye zilungelelaniswe ukuze zifumane i-high-quality roll weld joints.
