Oomatshini bokuwelda indawo ephakathi-frequency basetyenziswa ngokubanzi kumashishini ahlukeneyo okudibanisa amacandelo esinyithi. Aba matshini basebenzisa iindlela ezahlukeneyo zokulawula ukuqinisekisa ukuwelda okuchanekileyo kunye nokusebenza kakuhle. Kweli nqaku, siza kungena kwimigaqo yolawulo yeendlela ezahlukeneyo zolawulo ezisetyenziswa kumatshini wokuwelda amabala aphakathi.
- Ulawulo oluSekwe kwixesha: Ulawulo olusekelwe kwixesha yenye yezona ndlela zilula kwaye zisetyenziswa ngokuqhelekileyo kumatshini wokuwelda amabala aphakathi. Le ndlela ixhomekeke ekumiseleni ixesha lokuthunga elimiselweyo, ngexesha apho i-welding current kunye ne-voltage isetyenziswa kwii-workpieces. Iiparamitha ze-welding, ezifana nobukhulu bangoku kunye nobude, zikhethwa ngokusekelwe kwizinto ezidibeneyo kunye nomgangatho odibeneyo ofunekayo.
- Ulawulo oluSekwe ngoku: Ulawulo olusekwe ngoku lujolise ekugcineni i-welding eqhubekayo yangoku kuyo yonke inkqubo ye-welding. Le ndlela iqinisekisa ukuhanjiswa kobushushu obufanayo kunye nomgangatho we-weld. Ngokubeka iliso kunye nokulungelelanisa i-welding yangoku, abaqhubi banokufikelela kwii-welds ezihambelanayo kunye nezithembekileyo, nangona zijongene nokuhluka kwezinto eziphathekayo okanye ukuchasana.
- Ulawulo oluSekwe kwiVoltage: Ulawulo olusekwe kwi-Voltage lusetyenziswa ikakhulu ukuwelda indawo. Kubandakanya ukugcina i-voltage ezinzileyo kwii-electrodes ngexesha lenkqubo ye-welding. Le ndlela yokulawula iqinisekisa ukuba i-welding current ihlala ngaphakathi koluhlu olufunwayo, okubangela ukuba i-welds echanekileyo kunye nekhwalithi ephezulu.
- Ulawulo oluguquguqukayo: Iindlela zokulawula eziguquguqukayo zisebenzisa ingxelo yexesha langempela ukusuka kwi-sensor kunye neenkqubo zokubeka iliso ukulungelelanisa iiparamitha ze-welding njengoko inkqubo iqhubeka. Ezi nkqubo zinokusabela kwiinguqu zezinto eziphathekayo, ukugqoka i-electrode, okanye ezinye izinto eziguquguqukayo, ezivumela ukulungelelanisa kunye nokuzilungisa iinkqubo ze-welding. Le ndlela iluncedo kakhulu kuyilo oludityanisiweyo okanye oluguquguqukayo oludibeneyo.
- I-Pulsed Current Control: Ulawulo lwangoku lwe-Pulsed lubandakanya ukusebenzisa ii-pulses ezingapheliyo zangoku ngexesha lenkqubo ye-welding. Le ndlela inceda ukunciphisa ukubunjwa kobushushu kunye nokunciphisa umngcipheko wokuphazamiseka kwezinto okanye umonakalo. Ulawulo lwangoku lwe-pulsed lusetyenziswa ngokuqhelekileyo xa u-welding ebhityileyo okanye izinto ezinobushushu.
- Ulawulo oluSekwe ngokunyanzeliswa: Iisistim zolawulo ezisekwe ngamandla zibeka iliso kumandla oqhagamshelwano phakathi kwee-electrode kunye nezinto zokusebenza. Ngokugcina amandla ahambelanayo, ezi nkqubo ziqinisekisa ukuba i-electrode idibanisa ngokuqinileyo kunye nezinto ezixutywayo. Le ndlela yokulawula ibalulekile ekuveliseni i-welds ethembekileyo kwaye ehambelanayo.
- Ukujongwa kweNkqubo ye-Welding: Uninzi lwee-medium-frequency spot welding machines zibandakanya ukubeka iliso okuphambili kunye neenkqubo zokulawula umgangatho. Ezi nkqubo zinokuquka iimpawu ezifana nokuhlolwa kwe-weld seam, ukubhaqwa kwesiphene, kunye nokuloga kwedatha. Bavumela abaqhubi ukuba babeke iliso kwinkqubo ye-welding ngexesha langempela, bachonge iziphene, kwaye benze uhlengahlengiso oluyimfuneko ukuze kuqinisekiswe i-welds ephezulu.
Ukuqukumbela, oomatshini bokuwelda bamaxesha aphakathi basebenzisa iindlela ezahlukeneyo zokulawula ukufezekisa ukuwelda okuchanekileyo kunye nokusebenza kakuhle. Ukukhethwa kwendlela yokulawula kuxhomekeke kwisicelo esithile se-welding kunye neempawu zezinto eziphathekayo. Nokuba kusekwe kwixesha, kusekwe ngoku, kusekwe kwivoltheji, ukuguquguquka, ipulsed current, iforce-based, okanye iinkqubo zokubeka iliso ezihlanganisiweyo, ezi ndlela zolawulo zidlala indima ebalulekileyo ekuveliseni amajoyinti adityanisiweyo akumgangatho ophezulu kuluhlu olubanzi lwamashishini.
