1.Bohlokoa ba ho tjheseletsa ka lesela la masela
Ts'ebetso ea ho tjheseletsa e bohlokoa haholo tlhahisong ea tšepe ea lakane kaha e phetha karolo ea bohlokoa ho kopanya likarolo tsa tšepe ho theha mehaho e rarahaneng le lihlahisoa.
Lintlha tse ling ke tsena tse totobatsang bohlokoa ba lits'ebetso tsa welding hoho etsa lesela la tšepe:
1.1.Ho kopanya likarolo:Welding ke ea bohlokoa bakeng sa ho kopanya likarolo tsa tšepe tsa sheet sheet ho theha meaho e meholo joalo kamatlo, liforeimi, lelikopano.E etsa likamano tse matla le tse tšoarellang pakeng tsa likarolo tsa tšepe, tse nolofalletsang ho etsoa ha lihlahisoa tse rarahaneng le tse sebetsang.
1.2 Botšepehi ba sebopeho:Boleng ba ts'ebetso ea tjheseletsa bo ama ka ho toba botšepehi ba sebopeho sa likarolo tsa tšepe tse entsoeng.Welding e entsoeng ka nepo e tiisa hore likarolo tse kopaneng li ka mamella khatello ea mochini, maemo a tikoloho le litlhoko tse ling tsa ts'ebetso.
1.3 Ho tenyetseha ha moralo:Welding e fana ka sebopeho se feto-fetohang bakeng sa tlhahiso ea tšepe ea sheet, e lumellang ho theoa ha meaho e rarahaneng ea moetlo.E ka etsa likarolo tse nang le li-geometri tse rarahaneng, e lumellang bahlahisi ho fihlela litlhoko tse khethehileng tsa moralo le litlhaloso tsa ts'ebetso.
1.4 Tšebelisano 'moho:Mekhoa ea ho cheselletsa e bohlokoa bakeng sa ho kopanya mefuta e fapaneng ea lisebelisoa tsa tšepe, ho kenyeletsoa tšepe, aluminium, tšepe e sa hloekang le lisebelisoa tse ling.Ho feto-fetoha hona ho lumella ho etsoa ha lihlahisoa tse nang le mefuta e fapaneng ea lisebelisoa ho kopana le mefuta e mengata ea lits'ebetso tsa indasteri.
1.5 Tlhahiso e bolokang chelete e ngata:Mekhoa e metle ea li-welding e thusa ho boloka litšenyehelotlhahiso ea tšepeka ho nolofalletsa kopano e potlakileng le tlhahiso ea likarolo.Mokhoa o reriloeng hantle oa tjheseletsa o ka nolofatsa ts'ebetso ea tlhahiso, ka hona o fokotsa nako ea tlhahiso le ho theola litšenyehelo tsa kakaretso tsa tlhahiso.
1.6 Tiisetso ea Boleng:Ts'ebetso ea welding e bohlokoa ho netefatsa boleng le ts'epahalo ea lihlahisoa tsa letlapa la tšepe.Mekhoa e nepahetseng ea ho cheselletsa, ho kenyelletsa tlhahlobo le tlhahlobo ea weld, e bohlokoa ho boloka maemo a holimo a ts'ebetso le ts'ebetso ea sehlahisoa.
1.7 Likopo tsa Indasteri:Welding ho pharaletseng sebelisoa liindasteri tse sa tšoaneng, ho akarelletsa lekoloi, sefofane, kaho letlhahiso, kaelikarolo tsa tšepeke karolo ea bohlokoa ea tlhahiso ea likoloi, mechini, meaho le thepa ea bareki.
Ts'ebetso ea ho tjheseletsa e bohlokoa haholo tlhahisong ea tšepe ea letlapa kaha e lumella ho theoa ha lihlahisoa tse tšoarellang, tse sebetsang le tse sebetsang ka bongata.Ka ho utloisisa bohlokoa ba ho cheselletsa le ho kenya ts'ebetsong mekhoa e metle, bahlahisi ba ka fana ka likarolo tsa tšepe tsa boleng bo phahameng, tse theko e tlaase, le tse ka tšeptjoang bakeng sa mefuta e fapaneng ea lisebelisoa.
2. Ts'ebetso ea ho cheselletsa tšepe ea pampiri:
2.1 Boitokisetso:Mohato oa pele oa ho cheselletsa tšepe ke ho lokisa bokaholimo ba tšepe ka ho hloekisa le ho tlosa litšila leha e le life tse kang oli, mafura kapa mafome.Sena se bohlokoa bakeng sa ho fumana weld e matla le e hloekileng.
2.2JOint Design:Moralo o nepahetseng oa kopanelo o bohlokoa bakeng sa welding e atlehileng.Tlhophiso e kopaneng, ho kenyelletsa le mofuta o kopaneng (lenonyeletso la lap, lenonyeletso la butt, joalo-joalo) le kopano, li tla ama ts'ebetso ea welding le monyetla oa ho sotha.
2.3 Mekhoa ea ho cheseletsa:Ho na le mekhoa e mengata e sebelisoang ho tjheseletsa bakeng sa sheet metal, ho kenyeletswaTIG(khase ea tungsten inert) ho chesoa,MIG(khase ea inert ea tšepe) welding,resistance spot welding, joalo-joalo Mokhoa o mong le o mong o na le melemo le mathata a oona.
3.Mathata a tobaneng letjheseletsa la tshepe:
3.1 Deformation:Mocheso o hlahisoang nakong ea ts'ebetso ea welding o ka baka deformation ea tšepe le warping, haholo-holo bakeng sa aluminium e nang le conductivity e phahameng ea mocheso.Sena se ka lebisa ho se nepahaleng ha li-dimensional le ho ama boleng bohle ba karolo.
3.2 Ho qhekella:Ka lebaka la katoloso e phahameng ea mocheso le sekhahla sa ho honyela ha aluminium, e na le tšekamelo ea ho phatloha haholo nakong ea ts'ebetso ea welding.Taolo e nepahetseng ea li-parameter tsa welding e bohlokoa ho thibela mapetsong.
4.Laola ho khopama 'me u qobe mathata a li-welding:
Ho fokotsa ho khopama ha li-welding, maqheka le mekhoa e fapaneng e ka sebelisoa nakong ea ts'ebetso ea ho tjheseletsa ka lakane.Mona ke mekhoa e meng ea bohlokoa ea ho thusa ho laola le ho fokotsa ho khopama ha li-welding:
4.1 Tokiso e Nepahetseng:Ho sebelisa mekhoa e metle ea ho lokisa le ea clamping ho tšoaraworkpiecesebakeng sa ts'ebetso ea welding e thusa ho fokotsa motsamao le deformation.Sena se tiisa hore karolo e boloka sebopeho le boholo ba eona bo reriloeng nakong ea ts'ebetso ea welding.
4.2 Tatelano ea welding:Ho laola tatellano ea welding ho bohlokoa ho laola deformation.Ka ho rera ka hloko tatellano ea welding, ho kenya mocheso ho ka ajoa ka mokhoa o ts'oanang, ka hona ho fokotsa ho sotha ka kakaretso ha workpiece.
4.3 Phekolo ea mocheso oa preheating le post-weld:Ho futhumatsa mosebetsi pele ho tjheseletsa le ho etsa kalafo ea mocheso ka mor'a weld ho ka thusa ho fokotsa khatello ea maikutlo le ho fokotsa deformation.Sena se sebetsa ka ho khetheha bakeng sa lisebelisoa tse kang aluminium tse atisang ho senyeha nakong ea ho cheselletsa.
4.4 Mekhahlelo ea welding:Khetho e nepahetseng le taolo ea liparamente tsa welding joalo ka hona joale, voltage le lebelo la maeto li bohlokoa ho fokotsa ho khopama.Ka ho ntlafatsa litekanyo tsena, welding e ntle e ka finyelloa ka ho fokotsa mocheso o fokolang, o thusang ho laola ho khopama.
4.5 Theknoloji ea welding ea morao-rao:Ho sebelisa morao-mohato tjheseletsa thekenoloji, eo tjheseletsa e etsoa ka lehlakoreng le fapaneng ho tjheseletsa ho qetela, ho ka thusa offset deformation ka ho leka-lekanya liphello mocheso le ho fokotsa khatello ea kelello masala.
4.6 Tšebeliso ea li-jigs le lisebelisoa:Ho sebelisa li-jigs le li-fixtures tse etselitsoeng ka ho khetheha bakeng sa ts'ebetso ea welding ho thusa ho boloka ho lumellana le sebopeho se nepahetseng sa workpiece le ho fokotsa monyetla oa ho senyeha nakong ea ts'ebetso ea welding.
4.7 Khetho ea thepa:Ho khetha lisebelisoa tse nepahetseng tsa tšepe le li-filler le tsona li tla ama deformation ea welding.Ho bapisa tšepe ea ho tlatsa le tšepe ea motheo le ho khetha lisebelisoa tse nang le coefficient e tlase ea katoloso ea mocheso ho ka thusa ho fokotsa ho khopama.
4.8 Khetho ea mokhoa oa welding:Ho itšetlehile ka kopo e itseng, ho khetha mokhoa o nepahetseng ka ho fetisisa oa ho tjheseletsa, joalo ka TIG (tungsten inert gas) kapa MIG (metal inert gas) welding, ho ka thusa ho fokotsa ho khopama ka ho laola ho kenya mocheso le lebelo la ho tjheseletsa.
Ka ho kenya ts'ebetsong mekhoa le maano ana, ho khopama ha li-welding ho ka fokotsoa, haholo-holo ha ho sebetsa ka thepa e kang aluminium.E 'ngoe le e' ngoe ea mekhoa ena e phetha karolo ea bohlokoa ho laola deformation le ho netefatsa boleng ba weldment.
