I-Spot welding iyinqubo yokujoyina esetshenziswa kakhulu ezimbonini zokukhiqiza, okuhlanganisa imboni yezimoto kanye ne-aerospace.Emishinini yokushisela i-inverter ephakathi, ukumelana kwe-spot welding kudlala indima ebalulekile ekunqumeni ikhwalithi nokuthembeka kwe-weld.Lesi sihloko sihlola ukumelana okuhilelekile ekushiseleni kwendawo kanye nokubaluleka kwakho ekuzuzeni ama-welds aphumelelayo.
Incazelo yokumelana nokushisela indawo:
Ukumelana ne-spot welding kusho ukuphikiswa okuhlangatshezwana nakho amandla kagesi njengoba edlula ezintweni zokusebenza ezihlanganiswayo.Ukumelana kuthonywa yizici ezahlukahlukene, kufaka phakathi izakhiwo zezinto ezibonakalayo, izimo ezingaphezulu, ukwakheka kwe-electrode, nokumelana nokuxhumana phakathi kwama-electrode nezinto zokusebenza.
Izinto ezithinta ukumelana nokushisela endaweni:
Izinto ezibonakalayo: Izinto ezihlukile zibonisa ukuguquguquka kukagesi okuhlukahlukene, okuthinta ukumelana kwazo nokugeleza kwamanje kagesi ngesikhathi sokushisela.Izinto ezinokumelana nogesi okuphezulu, njengensimbi engagqwali, ngokuvamile zinokumelana okuphezulu uma kuqhathaniswa nezinto ezifana nekhopha noma i-aluminium.
Izimo ezingaphezulu: Ukuhlanzeka kanye nesimo sobuso bezinto zokusebenza kuthinta kakhulu ukuthintana kukagesi, ngenxa yalokho, ukumelana nokushiselwa kwendawo.I-oxidation, ama-coatings, noma ukungcola endaweni yokusebenza kungakhuphula ukumelana futhi kuvimbele ukwakheka kwe-weld eqinile.
Idizayini ye-Electrode: Idizayini nokuma kwama-electrode kuthonya indawo yokuxhumana kanye nengcindezi esetshenziswa ezintweni zokusebenza.Idizayini efanele ye-electrode iqinisekisa ukudluliswa kwamanje okusebenzayo futhi inciphisa ukumelana kusixhumi esibonakalayo se-electrode-workpiece.
Ukumelana nokuxhumana: Ukumelana nokuxhumana phakathi kwama-electrode nezinto zokusebenza kuthinta ukumelana okuphelele kwenqubo yokushisela indawo.Kubalulekile ukusungula ukuxhumana okuhle kukagesi phakathi kwama-electrode nezinto zokusebenza ukuze unciphise ukumelana nokwenza kube lula ukugeleza kwamanje okusebenzayo.
Ukubaluleka kokulawula ukumelana ku-spot welding:
Ukulawula ukumelana ekushiseleni kwendawo kubalulekile ukuze kuzuzwe ukushisela okungaguquki nokusezingeni eliphezulu.Ukumelana kuthinta ngqo isizukulwane sokushisa, ukwakheka kwe-nugget, namandla weld weld.Ukumelana okufanelekile kuqinisekisa okokufaka okwanele kokushisa ukuze kuncibilike indawo yokusebenza futhi kudale ibhondi eqinile ye-metallurgical.Ukuchezuka kokumelana kungaholela ekuhlanganisweni kwe-weld okwanele, amalunga abuthakathaka, noma ukulimala kwe-electrode.
Emishinini yokushisela i-frequency inverter ephakathi, ukumelana okubandakanyekayo ekushiseleni kwendawo kudlala indima enkulu enqubweni yokushisela.Ukuqonda izici ezithonya ukumelana nokuyilawula phakathi kwebanga elifunekayo kubalulekile ukuze kukhiqizwe izinto zokushisela ezithembekile neziqinile.Ngokulungiselela ukukhetha kwezinto ezibonakalayo, ukugcina izindawo zokusebenza ezihlanzekile, ukuklama ama-electrode afanele, kanye nokuqinisekisa ukuthintana okufanele kwe-electrode-to-workpiece, opharetha bangakwazi ukuphatha ngempumelelo ukumelana futhi bazuze ukushisela kwamabala okuphumelelayo ngekhwalithi nokusebenza okufiselekayo.
