I-Resistance spot welding yinkqubo yokuvelisa esetyenziswa ngokubanzi ebandakanya ukudibanisa amashiti esinyithi amabini okanye ngaphezulu kunye ngokufaka ubushushu kunye noxinzelelo kwiindawo ezithile. Ukwenza lo msebenzi ngokufanelekileyo, oomatshini bokuwelda indawo yokumelana bafuna umthombo othembekileyo wamandla ombane. Kweli nqaku, siza kuphonononga iindlela ezahlukeneyo zobonelelo lwamandla ezidla ngokusetyenziswa koomatshini bokuwelda bamabala okumelana.
- Ubonelelo lwaMandla lwangoku (DC):
- Amandla e-DC yeyona ndlela ixhaphakileyo kunye neyemveli esetyenziswa kwi-welding spot yokumelana. Inika ulawulo oluchanekileyo kwiiparamitha ze-welding.
- Kwi-DC spot welding, i-current ngqo idlula kwi-electrodes ye-welding. Le yangoku ivelisa ubushushu kwindawo yokuwelda, ibangela ukuba intsimbi inyibilike kwaye idibanise kunye.
- Ubonelelo lwaMandla lwangoku (AC):
- Ubonelelo lwamandla e-AC aluqhelekanga ukusetyenziswa kodwa luneenzuzo zalo, ngakumbi kwizicelo apho i-weld ethambileyo ifunwayo.
- I-AC spot welding ibonelela ngefuthe elifanayo lokufudumeza, elinokunciphisa umngcipheko wokutshisa kunye ne-warping kwizinto ezithile.
- Ubonelelo lwaMandla oluSekwe kwi-Inverter:
- Itekhnoloji ye-inverter iye yanda kakhulu kumatshini wokuwelda kwindawo yokumelana ngenxa yokusebenza kakuhle kwamandla kunye nokuguquguquka.
- Unikezelo lwamandla olusekwe kwi-inverter luguqula amandla angenayo e-AC abe yimveliso ye-DC elawulwayo, enikezela ngeenzuzo ze-DC kunye ne-AC welding.
- I-Capacitor Discharge Welding (CDW):
- I-CDW yindlela ekhethekileyo efanelekileyo kwimisebenzi ethambileyo kunye nencinci ye-welding.
- Kwi-CDW, amandla agcinwa kwibhanki ye-capacitor kwaye emva koko akhutshwe ngokukhawuleza nge-electrode ye-welding, ukudala i-arc emfutshane kodwa eqinile.
- I-Pulsed Welding:
- I-Pulsed welding yinto entsha yanamhlanje edibanisa iingenelo ze-DC kunye ne-AC welding.
- Ibandakanya ukugqabhuka kwamandla okwethutyana okuvumela ulawulo oluchanekileyo kwinkqubo ye-welding ngelixa unciphisa igalelo lobushushu.
- Ukuwelda kwi-Inverter ePhakathi:
- Le ndlela isetyenziswa ngokuqhelekileyo kwimveliso yeemoto kunye nezinye izicelo ze-welding ezikhawulezayo.
- I-welding ye-Medium-frequency welding inikezela ngokukhawuleza ukuhanjiswa kwamandla, ukunciphisa ixesha lomjikelo jikelele we-spot welding.
Nganye kwezi ndlela zonikezelo lwamandla zinamandla kunye nobuthathaka, okwenza ukuba zilungele izicelo ze-welding ezithile. Ukhetho lonikezelo lwamandla luxhomekeke kwizinto ezinje ngodidi lwezixhobo ezidityanisiweyo, umgangatho ofunekayo we-weld, isantya semveliso, kunye neemfuno zokonga amandla.
Ukuqukumbela, oomatshini bokuwelda banokuthi banikwe amandla ngeendlela ezahlukeneyo, nganye ibonelela ngeenzuzo ezizodwa ukuhlangabezana neemfuno ezahlukeneyo zokwenziwa kwemizi-mveliso. Ukukhethwa kwendlela efanelekileyo yokubonelela ngombane kubalulekile ekuqinisekiseni umgangatho kunye nokusebenza kakuhle kwenkqubo ye-spot welding.
