Inotiyela metal: izinhlobo, ubuchwepheshe

Labo abahlanganyela nokuxhashazwa izindlela ezahlukene, ngezinye izikhathi ebhekene isidingo ukwenza inotiyela phezu indawo eqondile. Broken iziqobosho, izingxenye ezigugile ngesikhatsi operation ngokwengxenye noma ngokuphelele, onqenqemeni, le bushing bakhathale. Ngayinye yalezi zimo kudinga Reconstitution inotiyela izinto usebenzisa entsha ungqimba metal kanzima ingxenye bakhathale. Ukuphathwa kanjalo ngeke nje alulame, kodwa futhi inikeza imininingwane entsha, izakhiwo ligugu. Ngokwesibonelo, ngokwenza Welding Imbondela usebenzisa ungqimba Carbide ngesisekelo aphansi izingxenye carbon steel, ungamukela ngento ukuqina anda noma eminye imikhiqizo ukusebenza.

Lona elula, kodwa ngesikhathi esifanayo, indlela ephumelelayo kufanelekile hhayi kuphela wokubuyiselwa ukuqina (ukusebenza) metal izingxenye. Ngu kungenzeka esebenzisa sebethule metal electrode iphethini ukulungiswa ngokuyizama izici iyunifomu ukuthuthukisa izakhiwo ungqimba ebusweni, ukusebenza emandleni futhi ihlala isikhathi eside.

Izici kanye Kwamagama: Umqondo oyisisekelo "inotiyela"

Iyini imfihlo lobu buchwepheshe, yini izici it has nokuthi ungasebenzisa kanjani ekuphileni, sizama ukuqonda ndawonye. Industrial ubuchwepheshe umfundi neze anentshisekelo, ikakhulukazi nokusetshenziswa imishini kunendawo enkulu engahlolwa amarobhothi. Ngenxa ziphathelene okwengeziwe sebethule metal izici ngesandla, isb esebenzisa Welding electrode.

Ekuphileni kwansuku zonke, leli gama umuntu metal okungenzeka unayo ekuphimiseni umbono kanye ingxubevange, isibonelo, steel. Uma lawa magama kungaba ngamazwi fingqa, e ukusetshenziswa kobuchwepheshe eqondiwe metal / ingxubevange nemininingwane tekusebenta kuhluke.

Cabanga ngokuningiliziwe isihloko akunakwenzeka ngenxa umthamo impahla ezihlongozwayo, ngoba ukuqala yazi nge inqubo, uqale uhlole imininingwane ukusebenza uhlobo metal akhethiwe. Konkhe lesikwentako ukukunikeza kulesi sihloko - izincomo ngesikhathi sebethule.

Ngokuvamile, ambozwe metal has ezifana Welding, ngeke ukuvikele ukufunda ubuchwepheshe bamuva esetshenziselwa ekucubunguleni izinsimbi kanye Alloys ezifana nethusi, aluminium, insimbi, insimbi engagqwali, futhi kwezinye ngokuya imininingwane yalolu imisebenzi ehlongozwayo.

Ngu Welding kwakwakhe metal ehloselwe uhlamvu heterogeneous ngokusebenzisa metal oncibilikisiwe phezu komunye. Ubizwa ngokuthi impahla yamathebhu ukuthi sisetshenziswa, main - nokucwaningwa ukuvundulula impatho-indlela sebethule metal.

izici kwezobuchwepheshe inqubo

I interpenetration metal ashisayo ku nomunye kwenzeka ezingeni yamangqamuzana ezinto eziphilayo.
