Ukugqwesa iZakhono zeZakhono zokuWelding ezithe nkqo kunye nangaphezulu

Uphando olutsha lugxininisa imiba ebalulekileyo ye-welding ethe nkqo kunye ne-overhead, ebonisa imiceli mngeni abajongene nayo i-welders ekufezekiseni iziphumo ezilungileyo kwezi zikhundla.

Ubunzima bendalo besinyithi esityhidiweyo budala ubunzima obukhulu ngenxa yokuba buhlala buhamba phantsi ngexesha lenkqubo ye-welding, okwenza kube nzima kakhulu ukudala i-weld ecocekileyo kunye nenhle. ekhokelela kwimiba ye-fusion kunye nokufakwa kwe-slag.

Ukoyisa le mingeni, iingcali zigxininisa imfuneko yokukhethwa ngokucokisekileyo kweeparamitha ezifanelekileyo ze-welding.Kucetyiswa ukuba kusetyenziswe indlela ye-welding ye-low current, i-arc i-welding eqhubekayo kunye nokusebenza kwe-arc emfutshane.Le ndlela inceda ukulawula ukushisa kunye nokuphucula amathuba okuphumelela. weld.

I-angle ye-welding nayo idlala indima ebalulekileyo kwi-welding ethe nkqo.Ukugcina i-angle ye-80 ukuya kwi-90 degree phakathi kwe-electrode kunye ne-weld iqinisekisa ukusabalalisa ubushushu obufanelekileyo kunye nokungena.Ukongeza ekukhetheni iiparamitha ezifanelekileyo ze-welding ngexesha lokukhwela ngokuthe nkqo kunye ne-overhead, ingqwalasela kufuneka ihlawulwe ekukhetheni iindlela ezifanelekileyo zokuthutha.Xa i-welding kwindawo ethe nkqo, iingcali zincoma ukusebenzisa i-crescent okanye i-zigzag electrodes.Ezi electrode zibonelela ngolawulo olungcono kunye nokuzinza ngexesha le-welding.Ukunyusa i-welding ephezulu, kucetyiswa ukuba usebenzise i-arc emfutshane echanekileyo okanye i-inclined ring conveyor ukuphucula umphumo. olu phononongo alubonakalisi kuphela ubunzima be-welding ethe nkqo kunye ne-overhead, kodwa inika isikhokelo esisebenzayo kubashicileli ukuphucula ubuchule babo.

Ngokusebenzisa iiparitha ezicetyiswayo ze-welding kunye neepatheni zokuthutha, i-welders inokuphucula umgangatho we-weld, ukunciphisa iziphene, kunye nokwandisa ukusebenza kakuhle.

Ukongeza, ukulandela iiprothokholi ezifanelekileyo zokhuseleko kunye nokusetyenziswa kwezixhobo ezifanelekileyo zokukhusela kubalulekile ekukhuseleni abashiseli kwiingozi ezinokubakho ngexesha lenkqubo ye-welding.Ngokugcina ezi zikhokelo engqondweni, i-welders inokuphucula izakhono zabo kwaye ifezekise iziphumo eziphezulu ze-welding kwizikhundla ezinzima.
