Tšebeliso ea Mahlaseli a Infrared ho Tlhahlobo ea Boleng ba Mechini ea Welding Spot Welding?

Mahlaseli a infrared ke sesebelisoa sa bohlokoa se ka sebelisoang ts'ebetsong ea tlhahlobo ea boleng ba mochini oa welding oa maqhubu a mahareng. Ka bokhoni ba eona ba ho lemoha le ho sekaseka mekhoa ea mocheso, mahlaseli a infrared a nolofalletsa tlhahlobo e sa senyeheng ea manonyeletso a weld, e fanang ka lintlha tsa bohlokoa mabapi le boleng ba welding. Sengoliloeng sena se hlahloba ts'ebeliso ea mahlaseli a infrared tlhahlobo ea boleng ba mechini ea welding spot welding ea maqhubu a mahareng.

1. Infrared Thermography for Weld Temperature Analysis: Infrared thermography e sebelisoa ho lekanya le ho sekaseka kabo ea mocheso holim'a lenonyeletso la weld nakong le ka mor'a ts'ebetso ea ho cheselletsa. Ka ho nka litšoantšo tsa mocheso, libaka tse chesang kapa ho fapana ha mocheso ho ka bonoa, ho bontša mathata a kang ho kopanngoa ho sa fellang, ho tlatsa fatše, kapa ho kenya mocheso o feteletseng. Sena se lumella basebelisi ho lekola boleng ba weld le ho etsa liphetoho tse hlokahalang ho ntlafatsa liparamente tsa welding.
2. Ho Khetholla Bofokoli le Tlhahlobo: Mahlaseli a mahlaseli a kotsi a ka thusa ho tseba le ho lekola mefokolo e fapaneng ea weld, joalo ka mapetsong, porosity le ho hloka ho kenella. Litšitiso tsena hangata li bonts'a li-signature tse fapaneng tsa mocheso ka lebaka la thepa ea tsona e fapaneng ea ho fetisa mocheso. Mekhoa ea ho nahana ka infrared e thusa ho bona mefokolo ena, e fana ka mokhoa o sa senyeheng oa ho lemoha le ho lekola liphoso. Basebelisi ba ka sebelisa tlhahisoleseling e fumanoeng litšoantšong tsa infrared ho tseba libaka tse amehang le ho nka mehato e nepahetseng ea ho lokisa.
3. Sebaka se Amehiloeng ke Mocheso (HAZ) Tlhahlobo: Sebaka se anngoeng ke mocheso se pota-potileng lenonyeletso la weld se bapala karolo ea bohlokoa ho fumana boleng ba kakaretso ea weld. Mahlaseli a infrared a lumella ho hlahlojoa ha HAZ ka ho hapa mekhoa ea mocheso le likhahla tsa mocheso sebakeng se haufi le weld. Tlhahlobo ena e thusa ho tseba liphetoho leha e le life tse sa rateheng linthong tse bonahalang, tse kang ho kenya mocheso o feteletseng o lebisang ho senyeha ha thepa kapa ho folisa ho sa lokelang ho bakang libaka tse brittle. Ka ho utloisisa litšoaneleho tsa HAZ, basebetsi ba ka fetola li-parameter tsa welding ho fokotsa liphello tsa eona tse mpe ho motsoako oa weld.
4. Tlhokomelo Sekhahla sa Pholiso ea Weld: Mahlaseli a infrared a ka sebelisoa ho lekola sekhahla sa ho pholisa ha lenonyeletso la weld kamora ts'ebetso ea welding. Ho pholisa ka potlako kapa ho sa leka-lekaneng ho ka lebisa ho thehoeng ha li-microstructures tse sa rateheng, tse kang boima bo feteletseng kapa khatello e setseng. Ka ho lekola phapang ea mocheso nakong ea ho pholisa, basebetsi ba ka lekola sekhahla sa ho pholisa le ho etsa litokiso ho netefatsa hore ho na le mocheso o nepahetseng, o hlahisang boleng bo ntlafetseng ba weld.

Ts'ebeliso ea mahlaseli a mahlaseli a kotsi tlhahlobong ea boleng ba mechini ea welding ea maqhubu a mahareng e fana ka leseli la bohlokoa mabapi le ts'ebetso ea welding le lithuso ho hlwaya litaba tse ka amang boleng ba weld. Ka ho sebelisa infrared thermography bakeng sa tlhahlobo ea mocheso, ho lemoha sekoli, tlhahlobo ea HAZ, le ho lekola litekanyetso tsa ho pholisa, basebelisi ba ka ntlafatsa maemo a ho tjheseletsa, ho tseba le ho rarolla mathata a welding, le ho netefatsa boleng bo tsitsitseng le bo tšepahalang ba weld. Ho kopanya mahlaseli a infrared e le karolo ea ts'ebetso ea tlhahlobo ea boleng ho ntlafatsa ts'ebetso le ts'ebetso e felletseng ea mechini ea welding ea maqhubu a mahareng a maqhubu a mahareng.
