DSAW kuwotcherera mfundo:
Kuwotcherera kwa arc kumadzi ndi kugwiritsa ntchito kuwotcherera kwa arc, Ndipo kuwotcherera kwa ma elekitirodi kumasiyana: waya wakuwotcherera wa arc umawonekera pamwamba popanda utoto, komabe, zomwe nthawi zambiri zimawona ma elekitirodi owotcherera pamwamba ndi zokutira wandiweyani kwambiri, kumiza kwa arc flux. kale anaika kukhala welded, kumizidwa arc kuwotcherera waya chimafikira mu flux, arc ikuyaka pansi flux.

Njira yowotcherera ya DSAW:
Wowotcherera waya kukhudzana ndi workpiece ndi kukanikiza chiyambi pambuyo kukanikiza batani, mphamvu ya mphindi ya waya ndi workpiece, waya Kuchotsa anayatsa arc kuwotcherera galimoto kupita patsogolo, waya mosalekeza zoyendera pansi, kupitiriza arc kuyaka mu solder. wosanjikiza pansipa arc mapangidwe weld dziwe.Kuzungulira arc, flux imasungunuka kuti ipange dzenje.Izi patsekeke ndi dziwe akupitiriza patsogolo, kupanga mosalekeza weld chithaphwi kumbuyo kulimba zitsulo.Njirayi ikuchitika pansi pa flux.Diso lamaliseche silingathe kuwona.

Spiral steel pipenjira kuwotcherera ndi ntchito basi kumizidwa arc kuwotcherera, ndondomeko kuwotcherera ndi dzuwa mkulu kupanga;kupanga nthawi yocheperako, kupulumutsa nthawi ya Rod;malo oyeretsera opanda spatter, sungani nthawi yoyeretsa;weld khalidwe.Komanso chikhalidwe chofunika kwa ozungulira zitsulo chitoliro wopanga Kutumiza ndi kungakupatseni, kotero kuti kuchuluka kwa malamulo kupanga nthawi, mbali ziwiri kumizidwa arc kuwotcherera ndondomeko chimagwiritsidwa ntchito pakupanga kuwotcherera chitoliro zitsulo.
