Kuve nechokwadi chekusimba kwewelding ye nut spot welding machines kwakakosha kuvimbisa kuvimbika uye kusimba kwemajoini akaiswa. Muchinyorwa chino, isu tichaongorora nzira dzekuyedza kusimba kwewelding ye nut spot welding michina. Nekuita bvunzo dzakakodzera, vagadziri vanogona kuonesa kunaka uye kutendeseka kweiyo welds, ichivagonesa kusangana nezvinodiwa uye zvakatemwa.
- Tensile Testing: Tensile bvunzo inzira inoshandiswa zvakanyanya yekuongorora kusimba kwewelding ye nut spot welds. Muedzo uyu unosanganisira kuisa axial load kujoinhi yakasungwa kusvika yasvika pakukundikana. Iyo yakanyanya simba yakatsungirirwa ne weld inoratidza simba rayo rekusimba. Tensile kuyedzwa kunogona kuitwa uchishandisa yakasarudzika yekuyedza michina, senge yepasirese yekuyedza muchina, inoyera mutoro uye deformation maitiro eiyo weld.
- Shear Testing: Kuveura bvunzo ndeimwe nzira yakajairika yekuongorora kusimba kwewelding ye nut spot welds. Muchiyedzo ichi, shear force inoiswa parallel kune weld interface kuti ione mutoro mukuru wejoint inogona kumira pamberi pekutadza. Kuyedzwa kweshear kunonyanya kukodzera maapplication ayo weld anosangana zvakanyanya nekuveura kushushikana, senge mufastener yekubatanidza.
- Peel Testing: Peel testing inonyanya kushandiswa kuongorora kusimba kwewelding yemajoini akaturikidzana, seaya anogadzirwa newelding nzungu pane sheet simbi. Muedzo uyu unosanganisira kuisa tensile load perpendicular kune ndege yejoint, zvichiita kuti weld iparare. Simba rinodiwa kutanga uye kuparadzira peel rinoratidza kusimba kweweld. Kuyedzwa kwepeel kunogona kuitwa uchishandisa midziyo yakasarudzika, senge peel tester, inoyera kupikisa kwepeel ye weld.
- Kuongorora Kwekuona: Kuongorora kwekuona kunoita basa rakakosha mukuongorora kunaka uye kutendeseka kwe nut spot welds. Vatariri vanoongorora nemeso mawelds ehurema hwakasiyana, senge isina kukwana fusion, porosity, makatsemuka, kana yakawandisa spatter. Kuongorora kwekuona kunofanirwa kuitwa zvinoenderana neyakagadzikwa zviyero uye zvakatemwa kuti ive nechokwadi chakaenderana kuongororwa kwesimba rewelding.
- Kusina-Kuparadza Kuyedzwa (NDT): Kusina-kuparadza nzira dzekuyedza, senge ultrasonic bvunzo kana radiographic bvunzo, inogona zvakare kushandiswa kuongorora kusimba kwewelding ye nut spot welds. Aya matekiniki anoshandisa matekinoroji epamberi kuti aone kukanganisa kwemukati kana kusawirirana mukati me weld, kupa ruzivo rwakakosha nezve weld mhando pasina kukanganisa.
Kuyedza kusimba kwewelding ye nut spot welding machines kwakakosha pakuona kutendeseka uye kuvimbika kwemajoini akasungwa. Nekushandisa nzira dzakaita sekutemesa kuyedza, kugera kuyedzwa, kuyedza peel, kuongorora kwekuona, uye kusaparadza kuyedza, vagadziri vanogona kuongorora kusimba uye mhando yewelds. Izvi zvinovatendera kuti vasangane nemiyero inodiwa uye zvakatemwa, zvichipa chivimbo mukuita kwe nut spot welding application.
