Ucwaningo olusha lugqamisa ukucatshangelwa okubalulekile kokushisela okuqondile nokuphezulu, okuveza izinselele abashiselayo ababhekana nazo ekuzuzeni imiphumela emihle kulezi zikhundla.
Amandla adonsela phansi emvelo ensimbi encibilikisiwe adala ubunzima obukhulu ngoba avame ukugeleza aye phansi phakathi nenqubo yokushisela, okwenza kube nzima kakhulu ukwakha i-weld ehlanzekile nenhle. okuholela ezindabeni ze-fusion kanye nokufakwa kwe-slag.
Ukuze unqobe lezi zinselele, ochwepheshe bagcizelela isidingo sokukhethwa ngokucophelela kwemingcele ye-welding efanelekile.Kunconywa ukusebenzisa indlela yokushisa yamanje ephansi, i-arc welding eqhubekayo kanye nokusebenza kwe-arc emfushane.Le ndlela isiza ukulawula ukushisa futhi ithuthukise amathuba okuphumelela. weld.
I-engeli yokushisela nayo idlala indima ebalulekile ekushiseleni okuqondile.Ukugcina i-engeli engu-80 kuya ku-90 degree phakathi kwe-electrode ne-weld kuqinisekisa ukusatshalaliswa kokushisa okufanele kanye nokungena.Ngaphezu kokukhetha imingcele ye-welding efanele ngesikhathi sokushisela okuqondile nokuphezulu, kufanele futhi kukhokhwe ekukhetheni izindlela zokuthutha ezifanele.Uma i-welding isendaweni eqondile, ochwepheshe batusa ukusebenzisa ama-electrode e-crescent noma ama-zigzag.Lawa ma-electrode ahlinzeka ngokulawula okungcono nokuzinza ngesikhathi sokushisela.Ngokwe-welding ephezulu, kunconywa ukusebenzisa i-arc emfushane eqondile noma i-inclined ring conveyor ukuze uthuthukise umphumela. lolu cwaningo alugcini nje ngokugqamisa ubunzima be-vertical and overhead welding, kodwa futhi lunikeze isiqondiso esisebenzayo sabashiseli ukuze bathuthukise amasu abo.
Ngokusebenzisa imingcele ye-welding enconyiwe kanye namaphethini okuthutha, ama-welders angathuthukisa ikhwalithi ye-weld, anciphise amaphutha, futhi andise ukusebenza kahle.
Ukwengeza, ukulandela izimiso zokuphepha ezifanele kanye nokusebenzisa izinto zokuzivikela ezifanele kubalulekile ekuvikeleni abashisela ezingozini ezingaba khona phakathi nenqubo yokushisela.Ngokugcina lezi ziqondiso engqondweni, abashiseli bangathuthukisa amakhono abo futhi bazuze imiphumela ephezulu yokushisela ezikhundleni eziyinselele.
