Matsakaicimitar tabo walda injiana amfani da su sosai a masana'antar zamani saboda babban inganci da kwanciyar hankali. Koyaya, samun daidaiton ingancin walda ya dogara sosai kan bincike na hankali da daidaita sigogin walda. Wannan labarin yana ba da taƙaitaccen jagora don inganta mahimman sigogin walda don ƙwararru.
Mabuɗin Mahimmanci da Muhimmancinsu
Mahimman sigogi sun haɗa da halin yanzu walda, lokacin walda, da matsa lamba na lantarki. Waɗannan kai tsaye suna shafar haɓakar walda nugget, ƙarfin haɗin gwiwa, da ingancin saman. Madaidaicin sarrafawa yana da mahimmanci don guje wa lahani kamar tafsiri, zafi mai zafi, ko rashin isashen shiga.
Hanyoyin Bincike
- Binciken Bayyanar Weld: Yi la'akari da siffar ƙugiya, santsin saman ƙasa, da daidaitawa don kimanta inganci da farko.
- Gwajin Injini: Yi gwaje-gwaje masu ƙarfi da ƙarfi don ƙididdige ƙarfin haɗin gwiwa.
- Kulawar thermal: Yi amfani da infrared thermography ko thermocouples don nazarin rarraba zafi da gano abubuwan da ba su da kyau.
Dabarun daidaitawa
- Welding Current: Ƙara halin yanzu don haɓaka shigarwar zafi da girman nugget, amma guje wa ƙima mai yawa don hana spatter da electrode stick. Rage halin yanzu don siraran kayan don rage murdiya.
- Lokacin walda: Tsara lokaci don zurfin shiga amma guje wa tsawan lokaci don rage zafi{0}} yankin da ya shafa (HAZ) da amfani da makamashi. Taqaitaccen lokaci don manyan kayan aiki -.
- Matsi na Electrode: Haɓaka matsa lamba don tabbatar da hulɗar fuska da sarrafa korar. Ƙananan matsa lamba na iya haifar da porosity, yayin da matsa lamba na iya haifar da nakasawa.
