Ha ho tluoa tabeng ea ho cheselletsa ka MIG, ho bohlokoa hore li-welders tse ncha li qale ka lintho tsa motheo ho theha motheo o tiileng oa katleho. Mokhoa ona ka kakaretso o tšoarela, o etsa hore ho be bonolo ho ithuta ho feta TIG welding, mohlala. E khona ho cheselletsa litšepe tse ngata, 'me joalo ka ts'ebetso e tsoelang pele e feptjoa, e fana ka lebelo le ts'ebetso e kholo ho feta ho cheselletsa lithupa.
Hammoho le ho itloaetsa, ho tseba lintlha tse ling tsa bohlokoa ho ka thusa li-welders tse ncha ho utloisisa hantle ts'ebetso ea welding ea MIG
Tšireletseho ea tjheseletsa
Ntho ea pele eo ho nahanoang ka eona bakeng sa li-welders tse ncha ke polokeho ea welding. Ho bohlokoa ho bala le ho latela lileibole kaofela le Bukana ea Mong'a thepa ka hloko pele u kenya, u sebetsa kapa u sebeletsa thepa ea ho cheseletsa. Li-welders li tlameha ho apara ts'ireletso e nepahetseng ea mahlo ho qoba ho chesoa ke arc flash le litlhase. Ka linako tsohle roala likhalase tsa tšireletso le helmete ea ho cheselletsa ho fihla boemong bo loketseng ba moriti. Liaparo tse nepahetseng tsa thepa ea ho itšireletsa li boetse li bohlokoa ho sireletsa letlalo ho tsosoa ke motlakase le ho chesa. Sena se kenyelletsa:
· Lieta tsa letlalo kapa lieta.
· Liatlana tsa ho cheselletsa letlalo kapa lelakabe tse sa cheseheng
· Baki ea tšubuhlellano e sa cheseheng kapa matsoho a tjheseletsang
Phefumoloho e lekaneng le eona ke ntlha ea bohlokoa ea polokeho. Ka linako tsohle ba cheselletsang litšepe ba lokela ho thibela hlooho ea bona hore e se ke ea lla le ho tiisa hore sebaka seo ba cheselletsang ho sona se na le moea o lekaneng. Ho ka 'na ha hlokahala mofuta o mong oa ho ntša mosi. Lithunya tse ntšang mosi tse ntšang mosi ho arc le tsona lia thusa, 'me li sebetsa hantle haholo ha li bapisoa le ho hapa fatše kapa siling.
Mekhoa ea phetisetso ea welding
Ho ipapisitsoe le lisebelisoa tsa motheo le khase e sireletsang, li-welders li ka tjheseletsa ka mekhoa e fapaneng ea phetisetso ea welding.
Potoloho e khuts'oane e tloaelehile bakeng sa lisebelisoa tse tšesaane 'me e sebetsa ka lebelo le tlase la welding le lebelo la phepelo ea terata, ka hona e lieha ho feta lits'ebetso tse ling. E boetse e atisa ho hlahisa spatter e hlokang ho hloekisa ka mor'a weld, empa ka kakaretso, ke mokhoa o bonolo oa ho o sebelisa.
Phetiso ea globular e sebetsa ka lebelo le phahameng la phepelo ea terata le li-voltages tsa welding ho feta potoloho e khuts'oane 'me e sebetsa bakeng sa welding ka terata e nang le flux-cored e nang le 100% carbon dioxide (CO2) (sheba lintlha tse mabapi le CO2 karolong e latelang). E ka sebelisoa ho lisebelisoa tsa motheo tsa 1/8-inch le tse teteaneng. Joalo ka welding ea MIG ea potoloho e khuts'oane, mokhoa ona o hlahisa spatter, empa ke ts'ebetso e potlakileng haholo.
Ho fetisoa ha spray ho fana ka arc e boreleli, e tsitsitseng, e etsang hore e ipiletse ho li-welders tse ngata tse ncha. E sebetsa ka li-amperage tse phahameng tsa welding le voltage, kahoo e potlakile ebile e hlahisa litholoana. E sebetsa hantle ho lisebelisoa tsa motheo tse 1/8 inch kapa ho feta.
Khase e sireletsang welding
Ntle le ho sireletsa letamo la weld ho tloha sepakapakeng, mofuta oa khase e sireletsang e sebelisoang bakeng sa welding ea MIG e ama ts'ebetso. Ho kenella ha weld, botsitso ba arc le thepa ea mochini e itšetlehile ka khase e sireletsang.
Khabone e otlolohileng ea carbon dioxide (CO2) e fana ka ts'ebetso e tebileng ea weld empa e na le arc e sa tsitsang le spatter e ngata. E sebelisoa bakeng sa tjheseletsa ea MIG ea potoloho e khuts'oane. Ho eketsa argon ho motsoako oa CO2 ho lumella tšebeliso ea phetiso ea spray bakeng sa tlhahiso e phahameng. Tekanyo ea 75% ea argon le 25% e tloaelehile.
Ka ntle ho lintho tsa motheo
Hammoho le ho itloaetsa, ho tseba lintlha tse ling tsa bohlokoa ho ka thusa li-welders tse ncha ho utloisisa hantle ts'ebetso ea welding ea MIG. Ho bohlokoa hape ho tloaelana le lisebelisoa, ho kenyeletsoa lithunya tse cheselletsang tsa MIG le lithapo tse chesellang. Ho utloisisa mokhoa oa ho khetha le ho boloka sesebelisoa sena ho ka lebisa hole ho theha ts'ebetso e ntle ea welding, boleng le tlhahiso.
