Manual arc welding: Ukuhlelwa, isicelo, ingakumbi

arc Manual segesi ne electrode camera yinkqubo, lo mthombo uphambili ubushushu leyo yenza njengoko i arc yombane. ucinezelo sokunikela isixa esikhulu ubushushu, oko kukhokelele kukunyibilikisa ngokukhawuleza iinxalenye eziphambili kunye nezinto welding - electrode.

circuit Ngokwemveli segesi iqulathe izinto eziliqela ezisisiseko zokusebenza: umthombo wamandla, welding cable kunye intambo phantsi, kwakunye kwesibambi kunye electrode umnikazi okhethekileyo.

Umbane ukuze anike efunekayo ngoku ukuze ucinezelo nokugcina inkqubo arcing. Manual arc welding udla kuxhaswe ivela kumthombo DC. Oku kuthetha ukuba ubonelelo ngoku kufuneka rhoqo naxa i electrode kwaziswa iindawo welding. Oku kugqalwa imfuneko enkulu kombane.

Hlala ngoku ifana inkqubo welding luchaphazela ngqo uzinzo arc, ngokwenjenjalo lula zentsimbi umsebenzi-abanezakhono. Enye inkalo uwunike apho izixhobo iwelding zahlulwa, - isixhobo olawula ubukhulu ye welding yangoku. Kunokuba elektroniki okanye mechanical. uhlengahlengiso Electronic, yena, yahlulwe kwi inverter kunye thyristor, mechanical nga kumelwa inductors Ukwanda okanye shunt ngemagnethi.

Kuxhomekeka kuhlobo imveliso ngoku uyazimela amaqela amabini eziphambili kwezixhobo: AC ne DC.

Imithombo AC zisetyenziselwa iwelding electro. DC isetyenziselwa inverter amandla kunye thyristor nezixhobo.

arc Manual segesi kwindawo ethile ngoku rhoqo wahlulwe indlela kokuxhuma kwipali ukuya ezimbaxa phambili kunye wokwephuka umva.

umnini electrode lenza umsebenzi elula ngokufanelekileyo kodwa ebalulekileyo - ubambe electrode ngelixa ngokunika qha zombane ezinqwenelekayo. Ukongeza, umnikazi sikhusela zentsimbi ukusuka yintshukumo yangoku yombane.

Manual arc welding na kwenziwa electrode ezikhethekileyo camera. Ezo zinto electrode olungundoqo uphathwa Ipeyinti ezahlukeneyo. Oku ukukhusela echibini weld, kwakunye ukuzinzisa le arc.

Iintambo kunye yamasango inkqubo welding esetyenziselwa elibaleka ngoku kwimiqolo abasebenza kunye nokukhuselwa kulo.

Kwakhona, musa phelisa "isixhobo" abangabancedani (amacebo leyo ethintela adhesion ukwenza ucinezelo oshushu afterburner arc). Umsebenzi omkhulu izixhobo ezinjalo kukuba lula ukusebenza kwezithuthi.

Njengoko kukhankanyiwe ngaphambili, manual arc welding kufuneka wenziwe usebenzisa electrode kunye ukutyabeka ekhethekileyo (ebizwa ngokuba yi-ukutyabeka). Le yokugqibela yenzelwe ukukhusela amacandelo ingenamthungo welding ukuba ukuthetha izinto eziphambili air yokucoca kwanangamacandelo alo.

Xa izinto eziphindaphindiweyo 4 uyazimela electrode amaqela eziphambili. Uluhlu lwabo - ngezantsi.

1. An coating asidi.
2. Rutile ngeso lenyama.
3. Le neselulosi ngeso lenyama.
4. Isiseko idyasi.

Manual arc welding lwenziwa yi nganye yezi ntlobo electrode, na iimpawu yesicelo, ukuba iingcali ukuze ukhethe ukhetho best for injongo ethile.
