Yintoni iSpot Welding

Spot welding luhlobo lweukumelana welding. Kubandakanya ukubeka ii-workpieces ezimbini phakathi kwee-electrode eziphezulu kunye nezisezantsi, ukuzifudumeza ngomsinga wombane, kunye nokufaka uxinzelelo lokudala i-plastic state kwindawo yokudibanisa yezinto zokusebenza, ezivumela ukuba zidibanise. Umgaqo wayo ulula: ngokuqhuba umbane ngee-electrode ezimbini zobhedu, ukuchasana kwandisa ubushushu bezinto zokusebenza, kubangele ukuba bancibilike kwaye badibanise. Yiyo loo nto ikwabizwa ngokuba yi-resistance welding. Xa kuthelekiswa nezinyeiinkqubo welding, i-spot welding ayifuni ukongeza izinto ze-welding, kwaye ukusebenza kulula.

Indlela yokubona iWeld?

1: Umsebenzi wokucoca uMphezulu

Spot Welding Ngokuqhelekileyo Materials

Aluminiyam: I-Aluminiyam ixhaphake kakhulu kwi-welding yendawo, ngakumbi kwishishini leemoto, apho iimpawu zayo ezikhaphukhaphu zinokuthatha indawo yezakhiwo eziqinileyo. Nangona kunjalo, i-aluminiyam ye-welding inzima kakhulu ngenxa ye-conductivity ephezulu, ifuna malunga nokuphindwe kabini okwangoku kwezinto eziqhelekileyo. Ke ngoko, xa udibanisa i-aluminium, kufuneka ukhethe izixhobo ezinamandla aphezulu.

Intsimbi: Intsimbi yeyona nto ixhaphakileyo kwiwelding yendawo. Yimpahla enzima, kwaye izinto ezininzi zeemoto zisebenzisa intsimbi. I-Spot welding isetyenziselwa ukuwelda imizimba yemoto kunye nezinto eziqinileyo ze nut.

Ubhedu: Spot welding ubhedu kufuna ubuchule obukhethekileyo. I-Copper ine-conductivity ephezulu ye-thermal kunye nombane, okwenza kube lula ukunamathela kwi-electrodes. Ngoko ke, sikhetha i-tungsten okanye i-molybdenum electrodes. Ngexesha le-welding, i-brazing material kufuneka yongezwe phakathi kwezinto ezimbini zokusebenza, ngoko ke ubhedu lusetyenziswa ngokuqhelekileyo.

Intsimbi yegalvanized: I-Welding intsimbi ye-galvanized inzima ngakumbi kunentsimbi ye-welding, efuna i-current ephezulu. Indawo yokuncibilika kwengubo ye-galvanized iphantsi kuneyentsimbi, ngoko kulula ukugqithisa kunye nokwenza i-splashes ngexesha le-welding.

Umsebenzi wokucoca uMphezulu woMphezulu

Phambi kwewelding, kubalulekile ukujonga ukuba i-workpieces inomhlwa okanye i-oxidation. Ukuba benjenjalo, ii-workpieces kufuneka zinyangwe. Ungasebenzisa i-sandpaper okanye i-grinder ukwenza umphezulu ube mpuluswa. Ngaphandle koko, kuya kubakho i-splatter eninzi, enokuchaphazela umgangatho we-welding.

Uxinzelelo

Ukukhetha uxinzelelo olufanelekileyo kubalulekile. Ukuba uxinzelelo lwe-electrode luphezulu kakhulu okanye luphantsi kakhulu, lunokunciphisa amandla e-weld kwaye lwandise ukusasazeka kwayo. Xa i-welding, kubalulekile ukuqwalasela iimpawu ze-workpiece xa ubeka uxinzelelo.

Ixesha le-Welding

Ukumisela ixesha elifanelekileyo le-welding kubalulekile. Ukuba ixesha le-welding lifutshane kakhulu, i-workpiece ayinakunyibilika ngokwaneleyo ukuhlangabezana neemfuno ze-welding. Kwelinye icala, ukuba ixesha lokuwelda lide kakhulu, i-workpiece ithambekele kwi-deformation, ekhokelela kumanqaku amakhulu e-weld.

I-Welding yangoku

I-welding yangoku kunye nexesha ziyancedisana, kodwa nazo zinemida yazo. Ukufumana ibhalansi elungileyo phakathi kwezi zibini ngundoqo ekuveliseni i-welds egqibeleleyo.

3: Spot Welding Machine

Isixhobo esifunekayo ukuwelda indawo aumatshini wokuwelda indawo, eza kwiimodeli ezahlukeneyo. Ukukhetha umatshini we-welding efanelekileyo kuxhomekeke kwiimpawu ze-workpiece kunye neemfuno ze-welding. Umzekelo, ukuba ufuna ukuwelda kunye iipleyiti ezimbini zentsimbi estainless 2mm ukufezekisa amandla afunekayo omzali, kuya kufuneka ukhethe umatshini wokuwelda onamandla aphezulu. Umatshini wokuwelda indawo osemgangathweni kunye ne-130KVA unokufeza oku. Nangona kunjalo, ukuba ufuna ukuwelda iipleyiti ze-aluminiyam eziyi-2mm, uya kufuna umatshini we-welding oqhelekileyo one-260KVA.

4: Beka i-Workpiece phakathi kwe-Electrodes kwaye uqalise i-Welding

Nje ukuba ukhethe umatshini wokuwelda ofanelekileyo, lixesha lokuba uqale ukuwelda. Emva kokudibanisa ukunikezelwa kwamandla kunye nokulungelelanisa iiparitha, faka i-workpiece elungiselelwe phakathi kwezi zibinii-electrode cap. Cinezela iqhosha le-pedal yeenyawo, kwaye i-electrode iya kucinezela phantsi, ifudumeza kwaye icinezele i-workpieces, ngaloo ndlela idibanisa iindawo zokudibanisa ezimbini zokusebenza kunye.

I-5: Uvavanyo lwe-Peel Emva kwe-Welding

Emva kokutshisa i-workpiece, kunzima ukuvavanya amandla e-weld ngeso lenyama lodwa. Kulapho kufuneka usebenzise izixhobo zokuvavanya amandla e-weld. Ukuvavanya i-Peel yindlela enkulu. Ngexesha lovavanyo lwe-peel, jonga amandla aphezulu afikelelekayo xa uxobula i-workpiece. Ezinye ii-workpieces zineemfuno ezithile zolu xabiso ukuze kubonwe ukuba i-weld yamkelekile.
