Kenyelletso ea Mefokolo le Morphologies e Khethehileng ho Mechini ea Welding ea Medium-Frequency Inverter Spot Welding

Mechineng ea ho tjheseletsa sebakeng sa maqhubu a mahareng, ho bohlokoa ho utloisisa mefokolo e fapaneng le li-morphology tse ikhethileng tse ka hlahang nakong ea ts'ebetso ea welding. Ho hlwaya mefokolo ena le ho utloisisa lisosa tsa bona ho ka thusa ho ntlafatsa boleng ba ho cheselletsa, ho ntlafatsa tlhahiso, le ho netefatsa ho ts'epahala ha manonyeletso a cheselitsoeng. Sengoliloeng sena se fana ka kakaretso ea liphoso tse tloaelehileng le morphologies e khethehileng e ka hlahang mochining oa tjheseletsa oa maqhubu a mahareng a maqhubu a mahareng.

1. Mefokolo ea Welding: 1.1 Porosity: Porosity e bolela boteng ba lipokotho tsa khase kapa likheo ka har'a lenonyeletso le cheselitsoeng. E ka etsahala ka lebaka la lintlha tse 'maloa, ho kenyelletsa le khase e sirelletsang e sa lokelang, tšilafalo, kapa ho se kenelle ha chese ka mokhoa o sa lekaneng. Ho fokotsa porosity, ho bohlokoa ho netefatsa tšireletso e nepahetseng ea khase, libaka tse hloekileng tsa mosebetsi, le ho ntlafatsa liparamente tsa welding.

1.2 Fusion e sa Phethahalang: Ho kopanngoa ho sa fellang ho etsahala ha ho se na maqhama a lekaneng pakeng tsa tšepe ea motheo le tšepe ea weld. Bothata bona bo ka lebisa ho manonyeletso a fokolang le ho fokotsa matla a mochine. Lintlha tse tlatsetsang ho kopanngoeng ho sa fellang li kenyelletsa ho kenya mocheso o sa lokelang, ho se lokisetsoe ka mokhoa o sa lokelang, kapa ho beoa ha li-electrode ho fosahetseng. Tekanyetso e nepahetseng ea li-electrode, ho kenya mocheso o loketseng, le ho netefatsa moralo o nepahetseng oa lenonyeletso la weld ho ka thusa ho thibela ho kopana ho sa phetheheng.

1.3 Cracks: Mapetso a cheseletso a ka hlaha ka lebaka la mabaka a fapaneng, joalo ka khatello e phahameng ea masala, ho kenya mocheso o feteletseng, kapa ho se lokisetsoe ka manonyeletso. Ho bohlokoa ho laola liparamente tsa tjheseletsa, ho qoba ho phophoma ka potlako, le ho etsa bonnete ba hore manonyeletso a lekana hantle le ho itokisa pele ho tjheseletsa ho fokotsa ho hlaha ha mapetso.

2. Special Morphologies: 2.1 Spatter: Spatter e bolela ho lelekoa ha tšepe e qhibilihisitsoeng nakong ea ts'ebetso ea ho cheselletsa. E ka bakoa ke lintlha tse joalo ka bongata bo phahameng ba hona joale, boemo bo fosahetseng ba li-electrode, kapa khase e sa lekaneng ea ho sireletsa. Ho fokotsa spatter, ho ntlafatsa liparamente tsa welding, ho boloka tekano e nepahetseng ea li-electrode, le ho netefatsa tšireletso e sebetsang ea khase e bohlokoa.

2.2 Undercut: Undercut ke groove kapa khatello ea maikutlo mathokong a sefaha sa weld. E hlaha ka lebaka la ho kenya mocheso o feteletseng kapa mokhoa o sa lokelang oa welding. Ho fokotsa undercut, ho bohlokoa ho laola ho kenya mocheso, ho boloka angle e nepahetseng ea elektrode le lebelo la ho tsamaea, le ho netefatsa hore ho na le tšepe e lekaneng ea ho tlatsa tšepe.

2.3 Ho Kena ho Feteletseng: Ho kenella ka mokhoa o feteletseng ho bolela ho qhibiliha ho feteletseng le ho kenella ka har'a tšepe ea motheo, e lebisang setšoantšong se sa rateheng sa weld. E ka bakoa ke nako e phahameng ea hona joale, linako tse telele tsa ho tjheseletsa, kapa khetho e sa lokelang ea li-electrode. Ho laola ho kenella ho feteletseng, ho ntlafatsa liparamente tsa welding, ho khetha li-electrode tse loketseng, le ho lekola letamo la weld ho bohlokoa.

Ho utloisisa mefokolo le li-morphology tse khethehileng tse ka hlahang mochining oa tjheseletsa oa maqhubu a mahareng a maqhubu a mahareng ho bohlokoa bakeng sa ho fihlela li-welds tsa boleng bo holimo. Ka ho tseba lisosa tsa mefokolo ena le ho kenya ts'ebetsong mehato e nepahetseng, joalo ka ho ntlafatsa likarolo tsa welding, ho netefatsa boitokiso bo nepahetseng bo kopaneng, le ho boloka tšireletso e lekaneng ea khase e sireletsang, bahlahisi ba ka fokotsa likoli, ba ntlafatsa boleng ba weld, le ho ntlafatsa ts'ebetso e akaretsang ea sebaka se mahareng sa maqhubu a inverter. metjhini ya ho tjheseletsa. Tlhahlobo ea khafetsa, koetliso ea basebetsi, le ho latela mekhoa e metle ea ho cheselletsa litšepe li bohlokoa ho fihlela li-welds tse tšepahalang le tse se nang sekoli.
