Resistance spot kuwotcherera ndi njira yomwe imagwiritsidwa ntchito kwambiri pamakampani opanga zinthu, pomwe zidutswa ziwiri kapena zingapo zazitsulo zimalumikizidwa palimodzi pogwiritsa ntchito kutentha ndi kukakamiza. Kuti mukwaniritse ma welds osasinthika komanso odalirika, ndikofunikira kumvetsetsa zinthu zitatu zazikuluzikulu zamakina omwe amawotcherera. M'nkhaniyi, tikambirana za zigawo zofunika izi ndi kufunika kwake pa ntchito kuwotcherera.
- Ma electrode
Ma electrode ndi mtima wa makina owotcherera omwe amakana. Iwo ali ndi udindo wopereka magetsi kuzinthu zogwirira ntchito komanso kukakamiza kuti apange weld wamphamvu. Ma elekitirodi amapangidwa ndi mkuwa chifukwa cha kusinthasintha kwake komanso kukana kutentha. Electrode yapamwamba, yotchedwa "electrode cap," imagwirizana mwachindunji ndi workpiece, pamene electrode yapansi ikugwirizana ndi workpiece kuchokera kumbali ina. Kukonzekera koyenera kwa ma elekitirodi, kuyanjanitsa, ndi kukonza ndizofunikira kuti zitsimikizire kuti ma welds osasinthasintha komanso ogwira mtima.
- Magetsi
Gawo lamagetsi limapereka mphamvu yamagetsi yofunikira pakuwotcherera malo oletsa. Imatembenuza magetsi okhazikika kukhala magetsi oyendetsedwa ndi magetsi ofunikira komanso magawo anthawi. Mphamvu yamagetsi imatsimikizira nthawi yowotcherera, nthawi yowotcherera, komanso mphamvu zonse zolowera mu weld. Kusiyanasiyana kwa magawowa kungakhudze kwambiri ubwino ndi mphamvu za weld. Makina owotcherera amakono oletsa kukana nthawi zambiri amakhala ndi zida zamagetsi zotsogola zokhazikika, zomwe zimalola kuwongolera bwino njira yowotcherera.
- Control System
Dongosolo loyang'anira ndi ubongo wa makina owotcherera omwe amakana. Imayang'anira ntchito yonse yowotcherera, kuphatikiza nthawi, kuthamanga kwapano, komanso kukakamiza komwe kumagwiritsidwa ntchito. Dongosolo lowongolera lopangidwa bwino limatsimikizira kubwereza komanso kusasinthika kwa ma welds. Limaperekanso zinthu zofunika zachitetezo, monga kuyimitsa mwadzidzidzi komanso kuzindikira zolakwika. Kupita patsogolo kwaukadaulo waukadaulo kwapangitsa kuti pakhale makina owongolera otsogola omwe amatha kuyang'anira ndikusintha magawo azowotcherera munthawi yeniyeni, zomwe zimapangitsa kuti pakhale ma welds apamwamba kwambiri, opanda chilema.
Pomaliza, makina owotcherera amakanema amadalira kulumikizana kogwirizana kwa maelekitirodi, magetsi, ndi makina owongolera kuti apange ma welds amphamvu komanso olimba. Kumvetsetsa zinthu zitatu izi ndizofunikira kwa ogwira ntchito ndi mainjiniya omwe amagwira ntchito ndiukadaulo uwu. Kukonzekera koyenera ndi kusanja kwa zigawozi ndizofunikanso kuti zitsimikizire kuti ntchito yowotcherera ndi yotetezeka komanso yotetezeka. Pamene ukadaulo ukupitilira kupita patsogolo, gawo la resistance spot welding latsala pang'ono kukhala lolondola kwambiri komanso logwirizana ndi zomwe opanga amakono apanga.
