Ho hanyetsa weldingke setso ho fetamokhoa oa ho cheselletsa, ke ka hona joale ho hlahisa mocheso oa ho hanyetsa ho kopanya li-workpieces tsa tšepe hammoho, tse sebelisoang haholo indastering ea kajeno.

Ho tjheseletsa letheba

Spot welding e arotsoe ka tjheseletsa e lehlakoreng le le leng, ho tjheseletsa ka mahlakoreng a mabedi, ho tjheseletsa ka matheba a mangata le ho tjheseletsa matheba ka tsela e iketsang. Mekhoa e fapaneng ea tjheseletsa ea matheba e ipapisitse le boholo ba thepa ea karolo e lokelang ho chesetsoa le litlhoko tsa hau tsa welding.

Resistance spot welding e tsamaisa motlakase ka li-electrode tse ka holimo le tse ka tlase, ho beha workpiece pakeng tsa li-electrode, le ho sebelisa khatello ea ho tlatsa tjheseletsa ea lakane ea tšepe. Re lokela ho hlokomela hore workpiece e lokela ho hloekisoa pele ho tjheseletsa, 'me bokaholimo ba motsoako oa solder bo boreleli ebile ha bo na tšilafalo. Mokhoa ona oa ho tjheseletsa o potlakile, lenonyeletso la welding le matla, mme ho bonolo ho iketsetsa. Leha ho le joalo, e lekanyelitsoe ho tjheseletsa e fetang pakeng tsa lipoleiti tse batlang li le tšesaane, 'me mefuta e mengata ea lihlahisoa tsa welding e lekanyelitsoe.

Ho tjheseletsa projeke

Ho fapana le ho cheselletsa letheba, ts'ebetso ea ho tjheseletsa ha projeke e hloka hore lehlakore le le leng la sebaka sa tjheseletsa sa workpiece le hloka ho ba le lintlha tsa convex, ha likarolo tse nang le projeke le lipoleiti tse bataletseng li hatelloa ke motlakase, lintlha tsena tsa convex li tla theha naha ea polasetiki le ho putlama. dikarolo tse pedi tsa tshepe di hokahane mmoho. Mokhoa ona oa tjheseletsa ka kakaretso o sebelisa li-electrode tse bataletseng, 'me hona joale oa tjheseletsa o moholo ho feta oa ho cheselletsa matheba.

Seam welding

Seam tjheseletsa ke tsoela pele letheba tjheseletsa, seam tjheseletsa eleketrode rolara sebopeho, feela joaloka mochine oa ho roka sebetsa, seam tjheseletsa ho sebetsa mekhoa e na le tsoelang pele seam tjheseletsa, intermittent seam tjheseletsa le mohato seam tjheseletsa. Li-electrode tsa roller li phutha 'me li tobetsa holim'a workpiece ho theha motsoako. Mokhoa ona oa ho tjheseletsa o na le tiiso e ntle mme o loketse ho tiisa le ho tjheseletsa dikarolo tsa tshepe tse kang meropa le makotikoti.

Ho tjheseletsa butt

The butt welding e arotsoe ka mekhoa e 'meli ea ho tjheseletsa, ho tjheseletsa butt butt le flash butt welding.

Resistance butt welding: Phapang e kholo ka ho tjheseletsa letheba ke hore ha ho tjheseletsa butt butt, 2 workpiece e behiloe, hona joale ke mocheso oa ho hanyetsa o hlahisoang ke ntlha ea ho kopana ea workpiece, ho e-na le electrode. Ha workpiece lenonyeletso e theha boemo ba polasetiki ka lebaka la mocheso, overforging khatello e sebelisoa ho workpiece, e le hore workpiece lenonyeletso fuses ho theha lenonyeletso tiileng. Ka kakaretso e sebelisoa bakeng sa ho tjheseletsa melamu ea koporo le lithapo tsa tšepe tse nang le sebaka se batlang se le senyane sa ho tšela.

Flash butt welding: Foromo ea welding e tšoana le ea resistance butt welding, empa ts'ebetsong ea welding, tšepe e qhibiliha ka potlako 'me ho tla hlahisoa litlhase. Ts'ebetso ena ea ho tjheseletsa e loketse bakeng sa ho tjheseletsa lisebelisoa tse kholo tse nang le likarolo tse fapaneng, tse sebelisoang ka kakaretso bakeng sa litšepe tsa tšepe, li-alloys tsa aluminium, koporo le tšepe tse sa tšoaneng tsa aluminium.

Ka holimo ke kenyelletso e khutšoanyane ea mefuta e mene ea ho hanyetsa tjheseletsa, ho hanyetsa ho tjheseletsa ho amanang le mekhoa e meng ea ho tjheseletsa, ho batla ho le ka seoelo ho batho ba tloaelehileng, empa ka sebele ke ts'ebetso ea bohlokoa haholo. Haeba u thahasella ho hanyetsa welding, u ka re latela ho ithuta ho eketsehileng ka mokhoa oa ho hanyetsa.
