Chiyambi cha Nozzle

Ma nozzles nthawi zambiri amanyalanyaza kuwotcherera pakuwotcherera. M'mbuyomu ntchito zaukadaulo, tidapeza kuti zolakwika zowotcherera nthawi zambiri zimachitika chifukwa chogwiritsa ntchito molakwika ma nozzles. Kusankha zida zoyenera za nozzle, kukula ndi mtundu kungathandize kuchepetsa nthawi yochepetsera, kutsika mtengo komanso kukulitsa luso la weld ndi zokolola.

Ntchito ya nozzle ndikuwongolera mpweya wotchinga ku dziwe losungunuka ndikuteteza dziwe losungunuka kuti lisaipitsidwe. Kusankha nozzle kungathe kuonetsetsa kuti mpweya woyenda bwino umalowa mu dziwe losungunuka losungunuka. Ngati nozzle yoyenera sinasankhidwe, kuwotchererako kumatha kukhala ndi zovuta zingapo kuphatikiza spatter yambiri ndi porosity, zomwe pamapeto pake zingayambitse kutsika chifukwa cha kukonzanso. Choncho kusankha nozzle yolondola n'kofunika kwambiri. Zotsatirazi zikuwonetsa ma nozzles angapo wamba komanso zabwino ndi zovuta zake.
mphuno yowongoka

#StraightNozzles

Mphuno zowongoka ndiye mtundu wodziwika bwino wa nozzles. Ubwino wake ndi wakuti amagwiritsidwa ntchito kwambiri ndipo angagwiritsidwe ntchito pazochitika zosiyanasiyana zowotcherera, ndipo mphamvu yotetezera mpweya ndi yabwino; kuipa kwake ndikwakuti chifukwa chakumapeto kokhuthala kwa mphuno, sikungalowe mwakuya pamene poyambira ndi yopapatiza, ndipo kutalika kwa waya wowotcherera kumapangitsa kuti arc ikhale yosakhazikika komanso kukhudza mpweya. Nthawi yomweyo, kutsogolo kutsogolo kutsekereza mzere wowonera kudzakhudzanso kuyang'ana kwa dziwe losungunuka ndi arc panthawi yowotcherera.

#ConeNozzle

Mipope ya conical imagwiritsidwa ntchito kwambiri powotcherera panjira yopapatiza. Mbali yakutsogolo ndi ya conical. Ubwino wake ndikuti kumapeto kwake kuli kochepa, kumatha kulowa mkati mozama, ndipo ndikosavuta kuwona mawonekedwe a dziwe losungunuka ndi arc; kuipa kwake ndikuti m'mimba mwake yakunja ndi yaying'ono, yomwe ingakhudze kutuluka kwa gasi. Kuteteza khalidwe, mabowo mpweya akhoza kwaiye pa kuwotcherera, ndi sipatter pa kuwotcherera ndi zotheka kutsekereza nozzle, ndipo m'malo pafupipafupi adzawonjezeka pa kuwotcherera kwa nthawi yaitali, zomwe zidzawonjezera mtengo.

Kuchokera pamphuno kupita ku nsonga yolumikizana

Ubale pakati pa nozzle ndi nsonga yolumikizana umakhudza kwambiri ubwino wa weld. Nsonga yolumikizana imatha kukhala yotsika kuposa mphuno kapena yokwera kuposa mphuno. A kukhudzana nsonga m'munsi kuposa nozzle angapereke bwino mpweya kutchinga khalidwe, koma nthawi yomweyo adzafupikitsa kutalika kwa ndodo-kunja kwa waya kuwotcherera, kukhala kovuta kuti kuwotcherera nyali kulowa poyambira. Mosiyana ndi zimenezi, nsonga yolumikizana yomwe ili yokwera kuposa mphuno ndi yabwino kuti ifike kumalo oletsedwa kapena bevel, koma khalidwe la chitetezo cha gasi lidzakhala losauka.

Chifukwa chake, wowotchererayo ayenera kusankha mphuno yoyenera pambuyo poyesa zabwino ndi zovuta zake.
