Umgaqo:
Izixhobo zokuwelda zombane kukusetyenziswa kwamandla ombane, ngokufudumeza kunye noxinzelelo, oko kukuthi, i-arc yobushushu obuphezulu obuveliswa yi-electrode elungileyo nengalunganga kwisekethe emfutshane yangoko, ukunyibilikisa i-solder kunye nezinto ezidityanisiweyo kwi-electrode, ngoncedo lokudibanisa kunye nokusasazwa kwee-athomu zetsimbi, ukuze ii-welds ezimbini okanye ngaphezulu zidityaniswe ngokuqinileyo kunye. Ngokukodwa iqulethwe nge-electrode, umatshini we-welding wombane, i-tong ye-welding yombane, i-grounding clamp kunye nentambo yokudibanisa. Ngokohlobo lonikezelo lwamandla ombane, lunokwahlulwa lube ziindidi ezimbini, enye ingumatshini we-AC welding kwaye enye yi-DC welding machine.
Umatshini wokuweldauqhagamshelwano:
• Iintambo ze-welding zidibaniswe kunye ne-welding tongs edibanisa imingxuma kumatshini we-welding ngokusebenzisa iingcingo zokudibanisa;
• I-grounding clamp idibaniswe kunye ne-grounding clamp yokudibanisa umgodi kumatshini we-welding ngocingo lokudibanisa;
• Beka i-weldment kwi-flux pad kwaye ubambe iqhosha lomhlaba kwelinye icala le-weldment;
• Emva koko cinezela isiphelo sentsikelelo ye-electrode kwimihlathi ye-welding;
• Isiseko esikhuselayo okanye uqhagamshelo lwe-zero lweqokobhe lomatshini wokuwelda (isixhobo sokumisa singasebenzisa umbhobho wobhedu okanye umbhobho wentsimbi ongenamthungo, ubunzulu bokungcwatywa kwawo emhlabeni kufuneka bube> 1m, kunye nokumelana nomhlaba kufuneka kube <4Ω), oko kukuthi, sebenzisa ucingo ukudibanisa isiphelo esinye kwisixhobo sokumisa kunye nesinye isiphelo ukuya kwisiphelo sokumisa iqokobhe leqokobhe.umatshini wokuwelda.
• Emva koko udibanise umatshini we-welding kunye nebhokisi yokusabalalisa ngomgca wokudibanisa, kwaye uqinisekise ukuba ubude bomgca wokudibanisa buyi-2 ukuya kwi-3 yeemitha, kunye nebhokisi lokusabalalisa kufuneka lixhotyiswe ngesixhobo sokukhusela ukugqithiswa komthwalo kunye nomtshini wokutshintsha ummese, njl., Enokulawula ukunikezelwa kwamandla omatshini welding ngokwahlukileyo.
• Phambi kwewelding, umqhubi kufuneka anxibe iimpahla zokuwelda, izihlangu zerabha ezigqunyiweyo, iiglavu zokhuselo, iimaski ezikhuselayo kunye nezinye izixhobo zokhuseleko, ukuze kuqinisekiswe ukhuseleko lobuqu lwalowo uqhubayo.
Ukudityaniswa kwegalelo lamandla kunye nemveliso yomatshini wokuwelda:
Ngokuqhelekileyo kukho izisombululo ezi-3 zomgca wokufakwa kwamandla: 1) intambo ephilayo, intambo engathathi hlangothi, kunye nocingo oluphantsi; 2)Iingcingo ezimbini eziphilileyo kunye nocingo olunye oluphantsi; 3)Iingcingo ezi-3 eziphilayo, ucingo olunye oluphantsi.
Umgca wokuphuma kumatshini wokuwelda wombane awahlulwanga ngaphandle komatshini wokuwelda we-AC, kodwa umatshini wokuwelda we-DC wahlulwe ube yinto elungileyo nengalunganga:
Umatshini we-DC welding uxhulumaniso olulungileyo lwe-polarity: Indlela yokudibanisa i-polarity ye-DC welding machine isekelwe kwi-workpiece njengereferensi, oko kukuthi, i-workpiece ye-welding idibaniswe ne-electrode ephumayo yomatshini we-welding yombane, kunye ne-welding handle (i-clamp) idibaniswe kwi-electrode engalunganga. I-arc yoqhagamshelwano olulungileyo luneempawu ezinzima, i-arc imxinwa kwaye ingumnqantsa, ubushushu bugxininise, ukungena kunamandla, ukungena okunzulu kunokufumaneka nge-current encinci, i-weld bead (weld) eyenziwe incinci, kwaye indlela ye-welding ilula ukuyilawula, kwaye ikwayeyona nto isetyenziswa kakhulu.
DC welding machine negative polarity connection connection (ekwabizwa ngokuba luqhagamshelo reverse polarity): workpiece iqhagamshelwe kwi electrode negative, kwaye umqheba welding idityaniswe kwi electrode positive. I-arc engalunganga ye-polarity ithambile, i-divergent, ukungena kwe-shallow, i-current enkulu kakhulu, i-spatter enkulu, kwaye ifanelekile kwiindawo ezineemfuno zenkqubo ye-welding ekhethekileyo, njenge-back cover surface of the cover back, i-welding ejongene nayo, apho i-welding bead ifuna iindawo ezibanzi kunye ne-flat, iipleyiti ezibhityileyo kunye neentsimbi ezikhethekileyo, njl njl. Ukongezelela, xa usebenzisa i-alkaline ephantsi-i-hydrogen electrode, uxhulumaniso olujikelezayo luzinzile ngakumbi kune-arc efanelekileyo, kwaye inani le-spatter lincinci.
Ngokubhekiselele kukusebenzisa uqhagamshelo olulungileyo lwe-polarity okanye indlela yokudityaniswa kwe-polarity engalunganga ngexesha le-welding, kufuneka kugqitywe ngokwenkqubo ye-welding,imeko weldingiimfuno kunye nezinto electrode.
Indlela yokugweba i-polarity yemveliso yomatshini we-welding we-DC: Umatshini we-welding oqhelekileyo uphawulwe nge- + kwaye - kwi-terminal ephumayo okanye kwibhodi ye-terminal, + ithetha ipali echanekileyo kwaye - ibonisa ipali engafanelekanga. Ukuba i-electrode e-positive kunye ne-negative ayibhalwanga, iindlela ezilandelayo zingasetyenziselwa ukuhlula.
1) Indlela yobuchule. Xa usebenzisa i-low-hydrogen (okanye i-alkali) i-electrodes ye-welding, ukuba ukutsha kwe-arc akuzinzile, i-spatter inkulu, kwaye isandi sinobudlova, kuthetha ukuba indlela yokudibanisa phambili isetyenzisiweyo; Kungenjalo, ibuyiselwa umva.
2) Indlela yentonga yamalahle. Xa indlela ye-carbon rod isetyenziselwa ukugqiba indlela yokudibanisa phambili okanye indlela yokudibanisa umva, inokugwetywa ngokuqwalasela i-arc kunye nezinye iimeko:
a. Ukuba ukutsha kwe-arc kuzinzile kwaye intonga yekhabhoni itshisa ngokukhawuleza, yindlela yokudibanisa efanelekileyo.
b. Ukuba ukutsha kwe-arc akuzinzile kwaye intonga yekhabhoni itshiswa kakhulu, yindlela yokudibanisa i-reverse.
3) Indlela yeMultimeter. Indlela kunye namanyathelo okusebenzisa i-multimeter ukugweba indlela yoqhagamshelwano lwangaphambili okanye indlela yoqhagamshelo ebuyela umva zezi:
a. Beka i-multimeter kuluhlu oluphezulu lwe-voltage ye-DC (ngaphezulu kwe-100V), okanye usebenzise i-voltmeter ye-DC.
b. Ipeni ye-multimeter kunye nomatshini we-welding we-DC zichukunyiswe ngokulandelanayo, ukuba kufunyaniswe ukuba isalathisi se-multimeter sijikisiwe nge-clockwise, ngoko i-terminal yomatshini we-welding edityaniswe nepeni ebomvu yi-polepositive pole, kwaye enye isiphelo sisibonda esibi. Ukuba uvavanya nge-multimeter yedijithali, xa kubonakala uphawu olubi, kuthetha ukuba ipeni ebomvu ixhunywe kwi-pole negative, kwaye akukho simboli ibonakala, oku kuthetha ukuba ipeni ebomvu ixhunyiwe kwi-polepositive pole.
Ngokuqinisekileyo, kumatshini wokuwelda osetyenziswayo, kusafuneka ujonge incwadi ehambelanayo.
Yiyo yonke iziseko ekwabelwana ngazo namhlanje kweli nqaku. Ukuba kukho nayiphi na into engafanelekanga, nceda uqonde kwaye ulungise
