Iwelding rectifier nedivaysi yayo

Kunzima ukuba nomfanekiso ishishini lokwakha okanye oomatshini ngaphandle ukuwelda. Yahlulahlulwe yaba iintlobo ezimbini: ngoku ngqo kunye nokuxuba.

Ukusebenzisa DC inika umgangatho ophezulu weld. Oku kungenxa yokusilela zero ngoku, yaye kungeso arcing uba uzinze, kunciphisa otshiza ukusuka kokutsha electrode, umthondo intsimbi onzulu ifunyenwe, kwizakhiwo weld amandla ngcono.
Ukongeza, izinto ezifana kwesinyithi, yodidi oluphezulu-ingxubevange, aluminiyamu nickel-based, ikopolo, titanium, ingasetyenziselwa ukuwelda kuphela current ngqo.

Ukuze ukuguqula yangoku nokuxuba kokuba rhoqo 50 Hz, a rhoqo wasebenzisa iwelding rectifier. Isebenzisa valve semiconductor ezizodwa izixhobo zolawulo transformer. Kukho iintlobo ezahlukeneyo izinto ezinjalo. Ngamnye kubo kubume bayo iyunithi ekulungiseni, iyunithi zokulinganisa ngenxa ekukhuseleni lezixhobo kunye namandla sombane.

Iwelding rectifier lisetyenziswa manual arc welding xa electrode linyibilike kwaye idaleka arc welding, apho lunceda angxamele xa ukwahlulwa kwicingo electrode amathontsi yesinyithi.

Ukunenzela lula, mechanical iwelding rectifier uhlobo olulodwa iwelding vd sombane, ukuba imo iswitshi ekude. converters olunjalo luphawulwa izisombululo eziziiprayimari zobugcisa:

• kuluhlu efanayo ukuwelda hlengiso yangoku ziindlela ezigudileyo;
• uqhekeko shunt Imagnethi uyilo tyaba enokususwa, inika hlengahlengiso mechanical le weld, iye isakhiwo elula;
• engathi transformer ezenziwe ngobhedu;
• akukho ezihambayo coil;
• zokupholisa umoya;
• ucinezelo lulula lwenziwa, i arc uzinzile;
• iklasi yokwambathisa - H;
• izihlanganisi zangoku ngokukhuselekileyo ngokukhawuleza ivula;
• kwemiqathango welding ukuhlela rectifier yale hlobo kulula ukuhamba.

Ngamanye amaxesha, ekhaya kukho imfuneko yokuba enze umsebenzi welding. Kule meko kukho ezimbini iinketho - ukuthenga umatshini esele zenziwe okanye benze iwelding rectifier ngezandla zabo.

Into ephambili i sombane rectifier ngcono lokuguqula ombane AC umgca nokubonelela ubungakanani oluyimfuneko nomgangatho weld yangoku. Ixhume kuyenzeka ukunxibelelana ombane ka-220 V, kwaye imveliso kufuneka inike 40-70 V.

Ecaleni iterminal transformer kufuneka solder intambo malunga omise 2.5 isikwere ubukhulu, kunye nobude malunga kweemitha ezi-5, intshukumo lula kumatshini welding. Le cingo Kungcono usebenzise bodwa kabini.

Inqanaba elilandelayo - ukulungiselela iintambo welding. Ukulungiselela le njongo kubhetele ukusebenzisa wire ethambileyo ngerabha yokugquma, ubuncinane ezimbini ubude. Kwenye Ekupheleni cable zibambene clothespin "izihlwele" (ngamanye amaxesha imoto "kulula" zingasetyenziswa) Kwelinye intambo - umnini electrode.

Ngoku ke kufuneka ukuba uhlanganise rectifier welding. Ukusuka oku kuxhomekeka kwindlela ifowuni lula ukusebenza. Xa umsebenzi, iya kuba shushu, ngoko ke izindlu kufuneka zinikwe ezinemingxuma ofaka umoya. Kuba izithuthi lula kwi izindlu Bopha isiphatho uze usete kweevili. yokubekwa kunokwenzeka of kwiingcingo kunye neengcingo ifake amacandelo owongezelelweyo ngendlela ngamagwegwe, washer, kwizibiyeli.
