I-Resistance spot welding yinkqubo esetyenziswa ngokubanzi kumashishini ahlukeneyo, kuquka iimoto, i-aerospace, kunye ne-electronics. Obu buchule bubandakanya ukudibanisa iziqwenga zentsimbi ezimbini okanye ngaphezulu ngokufaka ubushushu kunye noxinzelelo kwiindawo ezithile. Umgangatho we-spot weld ubalulekile ekusebenzeni ngokubanzi kunye nokuqina kwemveliso egqityiweyo. Kweli nqaku, siza kuphonononga izinto ezintathu eziphambili eziphembelela ukuxhathisa indawo ye-welding kunye nefuthe labo kwinkqubo ye-welding kunye nemveliso yokugqibela.
- Ubunzulu bangoku (Amperage)
Ukuqina kwangoku, kulinganiswe nge-amperes, yiparameter esisiseko kwi-resistance spot welding. Inquma ubungakanani bobushushu obuveliswa kwindawo ye-welding. Xa i-current iphantsi kakhulu, ukushisa okunganeleyo kuveliswa, okukhokelela kwi-welds ebuthakathaka kwaye engaphelelanga. Ngokuchasene noko, ukugqithisa kwangoku kunokubangela ukushisa, okukhokelela ekutshiseni okanye ukonakala kwezinto zokusebenza.
Ukufezekisa umgangatho we-weld ogqwesileyo, kubalulekile ukukhetha ubunzulu obufanelekileyo ngoku ngokusekwe kuhlobo lwemathiriyeli kunye nobukhulu. Iinjineli ze-welding kunye neechwephesha kufuneka zibale ngononophelo kwaye zisete okwangoku ukuze kuqinisekiswe i-welds engaguqukiyo kwaye ethembekileyo.
- Ixesha le-Welding
Ixesha le-welding, elihlala lilinganiswa ngee-milliseconds, yenye into ebalulekileyo ekuxhathiseni ukuwelda kwendawo. Inquma ukuba ixesha elingakanani elikhoyo lihamba kwiindawo zokusebenza, ezichaphazela ubungakanani kunye namandla e-weld nugget-inxalenye enyibilikisiweyo kunye nedibeneyo yezinto eziphathekayo.
Amaxesha amafutshane e-welding asenokunganikeli ubushushu obaneleyo bokudala i-weld eyomeleleyo, ngelixa amaxesha amade kakhulu anokukhokelela ekuthomalalisweni kwezixhobo kunye nokunciphisa amandla e-weld. Ukufumana ibhalansi efanelekileyo kubalulekile ekufezekiseni i-weld kunye neempawu ezifunwayo.
- Uxinzelelo (i-Electrode Force)
Uxinzelelo, olusetyenziswa ngee-electrode zokuwelda, ludlala indima ebalulekileyo kwi-welding spot yokumelana. Izisa ii-workpieces kuqhagamshelwano olusondeleyo, iqinisekisa uqhagamshelwano olulungileyo lombane kunye nokukhuthaza ukuhanjiswa kobushushu. Uxinzelelo olusetyenzisiweyo lufanele lwanele ukubamba izinto kunye ngexesha nangemva kwenkqubo ye-welding.
Uxinzelelo olungonelanga lunokukhokelela kumgangatho ophantsi we-weld, njengoko kunokubangela izithuba phakathi kwezinto zokusebenza okanye ukungena ngokwaneleyo. Ngakolunye uhlangothi, uxinzelelo olugqithisileyo lunokuphazamisa okanye lonakalise izinto eziphathekayo, luchaphazela kakubi ukunyaniseka kwesakhiwo.
Ukuqukumbela, umgangatho wokumelana ne-welding spot uphenjelelwa kakhulu zizinto ezintathu eziphambili: ukuqina kwangoku, ixesha le-welding, kunye noxinzelelo. Ukulinganisa ezi parameters kubalulekile ekufezekiseni iiwelds ezihlangabezana nemigangatho efunekayo yamandla, ukuqina, kunye nenkangeleko. Abaqhubi be-welding kunye neenjineli kufuneka baqwalasele ngononophelo ezi zinto kwaye bahlale bebeka iliso kwaye bahlengahlengise ukuqinisekisa ezona ziphumo zibalaseleyo ze-welding kwizicelo ezahlukeneyo.
