Ukuba umtsha ekuchaseni i-welding okanye ujonge ukuqonda okucacileyo kwayo, kuya kufuneka ngokuqinisekileyo ulifunde eli nqaku ngononophelo. Eli nqaku liza kukuthatha ungene nzulu kwihlabathi le-resistance welding. Nokuba ungumqali okanye ujonge ukwandisa ulwazi lwakho, eli nqaku liza kukunika ulwazi oluxabisekileyo.
Yintoni i-Resistance Welding?
I-Resistance welding yindlela yokudibanisa isinyithi esinesantya esiphezulu, esinoqoqosho. Ubuchwephesha bokuwelda bufanelekile kumalungu emilenze, amalunga empundu, okanye adityanisiweyo angafuni kuxinana komoya, anobunzima obungaphantsi kwe-6mm kwizakhiwo zeshiti elibhityileyo. Ewe kunjalo, iyakwazi ukuwelda iintsimbi ezityebileyo nezikhudlwana, kodwa ukusebenza kwayo iyonke kusenokungabi kuhle njengezinye iindlela zokuwelda.
Inkcazo kunye neZiseko
Ukumelana ne-weldingyindlela apho izixhobo zokusebenza eziza kudityaniswa zibekwe phakathi kwee-electrode ezimbini. Ngokudlula okwangoku kwii-workpieces kunye namanqaku oqhagamshelwano, ukufudumeza ukuchasana kwenzeka, ukuvelisa ubushushu ekudibaneni kwezinto zokusebenza. Oku kufudumeza kwendawo kubangela ukuba indawo inyibilike okanye ibe pliable, ngelixa uxinzelelo oluvela kwii-electrode ezimbini ludibanisa isinyithi kunye.
Xa ikhoyo ngoku ihamba nge-conductor, ivelisa ubushushu ngenxa yokumelana. Ukuphakama kokuchasana xa ikhoyo ngoku isigxina, ubushushu obuninzi buveliswa. Kwinqanaba apho iintsimbi zidibene khona, ukuchasana kukhulu kakhulu kunokuba ngaphakathi kwentsimbi ngokwayo. Ngoko ke, xa umsinga omkhulu udlula kuqhagamshelwano phakathi kwesinyithi kunye ne-electrode, isinyithi sitshisa ngokukhawuleza ngenxa yobushushu obukhulu. Ngeli xesha, isinyithi siba yi-ductile kakhulu, kwaye ngoxinzelelo olusetyenzisiweyo, iziqwenga ezimbini zetsimbi zibophene ngokukhuselekileyo.
Resistance Welding Umgaqo wokuSebenza
Umgaqo we-resistance spot welding kunye nokwakheka kwamalungu kuboniswe kuMzobo 1-1. Isinyithi A kunye nentsimbi B zibekwe phakathi kwee-electrode ezimbini, kwaye uxinzelelo lusetyenziswa kwii-electrodes. Umbane onamandla ugqithiswa phakathi kwee-electrode ezimbini nge-transformer ye-resistance welder. Imiphezulu yoqhagamshelwano yeendawo zokusebenza zenza indawo yokudibanisa ngokomzimba, eyandisa ngokuthe ngcembe njengoko ikhoyo ngoku ishushu. I-deformation yeplastiki kunye nokushisa ngokuqhubekayo kusebenze ii-athomu kwindawo yoqhagamshelwano, ekhokelela ekubunjweni kwesiseko esityhidiweyo. Undoqo otyhidiweyo ukhula ngendlela yeekristale zekholomu, ukutyhala izinto eziphezulu zoxinzelelo lwealloy ukuya komnye. Xa i-electrodes ye-welder isuka kumphezulu wesinyithi, kwaye isinyithi sipholile, i-workpieces idityaniswe kunye, idala ibhondi yentsimbi eyomeleleyo. Umphezulu odibeneyo uyanyamalala, ushiye emva kwe-weld nugget.

Izinto ezichaphazela i-Resistance Welding
Ukumelana ne-weldingyindlela yokuwelda esebenzisa umsinga wombane ukuvelisa ubushushu ukudibanisa amacandelo esinyithi. Njengoko kukhankanyiwe ngaphambili, umgaqo wokuxhathisa i-welding ngokuyinhloko uvela kumthetho kaJoule wokufudumeza, apho isizukulwana sokushisa kwe-welding ngokuyinhloko sinqunywe yiparameters ezifana nangoku, ukuxhathisa, kunye nexesha le-welding. Inokubonakaliswa ngale fomyula ilandelayo:
Q = I²Rt
Intsingiselo yepharamitha yewelding nganye:
Q - Ubushushu (J)
Mna - Welding current (A)
R — Ukuchasa (Ω)
t - Ixesha lokuwelda (s)
I-Welding yangoku
Ikhoyo ngoku inempembelelo enkulu ekushiseni okwenziwa ngexesha le-welding, njengoko kuboniswe kwifomula. Ixabiso lesikwere sangoku lichaphazela ukushisa, oku kuthetha ukuba ukuphakama kwangoku, ngokukhawuleza ukushisa kuya kwanda. Ke ngoko, xa uhlengahlengisa iiparitha ze-welding ngaphambi kwe-welding, kubalulekile ukuseta umsinga ofanelekileyo. Ukuba i-welding current incinci kakhulu, i-weld ayiyi kunyibilika, kwaye akukho ngundoqo we-fusion uya kwenza. Ukuba i-current inkulu kakhulu, i-fusion core iya kukhula ngokukhawuleza, ibangele ukutshiza ngokugqithiseleyo ngexesha le-welding kunye nokonakalisa i-electrodes.
I-Welding yangoku ihlulwe kakhulu ibe yi-alternating current (AC) kunye ne-direct current (DC), njengoko kuboniswe kumzobo ongezantsi. Ioomatshini bokuwelda amabalasisebenzisa nazo zahlulwe koomatshini bokuwelda bangoku ngokuthe ngqo kunye nokutshintshana koomatshini bokuwelda bangoku. Oomatshini bokuwelda bangoku ngokuthe ngqo basebenzisa isigaba sesithathu sonikezelo lwamandla, ukuqinisekisa ukuhanjiswa kwamandla okulinganayo, kwaye banokufikelela kwi-welding frequencies ezingaphezu kwe-1000 Hz, okukhokelela ekuchanekeni kwe-welding ephezulu. Bakwanayo nenzuzo yemfuno ephantsi yamandla ukusuka kwigridi yamandla, okwenza ezi welders zonga amandla zithandwa kakhulu phakathi kwabavelisi beshishini lokuvelisa. Ukutshintshana koomatshini bokuwelda bangoku banesigaba esinye semveliso ye-50Hz, umthamo ophezulu oqhubekayo womthwalo, kunye neemfuno eziphezulu zegridi yamandla. Ukongeza, banamandla okuwelda aphantsi, afuna amaxesha amade welding.
Qhagamshelana Ukumelana
Ukusuka kwifomula, kulula ukubona ukuba ukuxhathisa kuhambelana ngokuthe ngqo nobushushu obuveliswayo. Ukuphakama kokumelana, ubukhulu bobushushu obuveliswayo ngexesha le-welding. Ukuchasana kusasazwa kwiindawo ezahlukeneyo ze-electrode kunye ne-workpiece. Ngexesha le-welding, ukuchasana okuphezulu kwenzeka kwindawo yoqhagamshelwano ye-workpiece, okukhokelela kwisizukulwana esiphezulu sokushisa. Okulandelayo ukuchasana kwindawo yoqhagamshelwano phakathi kwe-workpiece kunye ne-electrode. Nangona kunjalo, ekubeni i-electrode ipholile ngamanzi kwaye ipholile ngokukhawuleza, ubushushu buyancipha ngokukhawuleza. Ngakolunye uhlangothi, ukuchasana koqhagamshelwano phakathi kwee-workpieces, nangona kuyanyamalala, kunokutshatyalaliswa kokushisa okungahambi kakuhle, okukhokelela kumaqondo aphezulu. Ke ngoko, indawo encinci kuphela phakathi kwezixhobo zokusebenza inokufikelela kubushushu obuyimfuneko ukwenza i-fusion core kunye ne-weld kunye.
Ukongezelela, ubushushu kunye noxinzelelo lwe-electrode luchaphazela ukuchasana. Njengoko iqondo lokushisa liphakama, amandla okuvelisa isinyithi ayancipha, ukwandisa indawo yoqhagamshelwano phakathi kwezinto zokusebenza kunye naphakathi kwendawo yokusebenza kunye ne-electrode, okubangela ukunyanzeliswa kwehle. Ukwandisa uxinzelelo lwe-electrode kwenza ukuba indawo yokusebenza ibe lula, ikhulise indawo yoqhagamshelwano kunye nokunciphisa ukuxhathisa. Ngenxa yoko, kukho isenzeko apho, ngexesha lokuwelda kwezixhobo eziqhelekileyo, ukuchasana kuyanda kamsinya emva kokukhanyisa, kwaye xa amandla ecinyiwe kunye neefom ze-fusion core, ukuchasana kuqala ukuncipha.
Ixesha le-Welding
Okukhona ixesha lokuwelda lide, kokukhona ubushushu buveliswa phezulu. Kule fomyula, okwangoku kunye nexesha zinokuncedisana. Xa ufuna i-weld eyomeleleyo, unokuseta umsinga ophezulu ixesha elifutshane ukuvelisa ubushushu ngokukhawuleza kwaye wenze i-fusion core ukugqiba i-welding. Kungenjalo, unokuseta umsinga ophantsi ixesha elide, kodwa kukho umda kule ndlela. Ukuba ixesha libekwe ixesha elide, kunokukhokelela ekutshizeni okugqithisileyo kwaye kunokubangela ukuba i-electrode ibambelele. Nokuba yeyangoku okanye lixesha, kukho imida. Xa ubeka iiparitha, kufuneka uqwalasele izinto kunye nobukhulu bomsebenzi, kunye namandla omatshini we-welding.
Iimpahla zeMathiriyeli
Izinto eziphathekayo ze-workpiece zichaphazela kakhulu ukumelana kwayo, okudlala indima ebalulekileyo ekuveliseni ukushisa kwe-welding. Xa welding steel stainless, ene-resistivity ephezulu kunye nokungahambi kakuhle kwe-thermal, kulula ukuvelisa ubushushu kodwa kunzima ukubuchitha, ngoko ke imisinga emincinci iyafuneka. Xa ukuwelda iialloyi ze-aluminiyam kunye ne-resistivity ephantsi kunye ne-thermal conductivity enhle, kunzima ukuvelisa ubushushu kodwa kulula ukubuchitha, ngoko ke imisinga emikhulu iyafuneka. Iintsimbi ezifana nesilivere kunye nobhedu zine-conductivity ephezulu ye-thermal kunye ne-resistivity ephantsi, ngoko ke kunye nemisinga ephezulu, ayenzi bushushu obuninzi kodwa inokubuhambisa kude. Ke ngoko, ezi zinyithi azifanelekanga kwi-welding yokumelana kodwa zinokusetyenziswa njengezinto ze-electrode.
Uyilo lwe-Electrode kunye neJometri
Ubume kunye nezinto eziphathekayo ze-electrode nazo zichaphazela ukuveliswa kobushushu. Indawo yoqhagamshelwano phakathi kwe-electrode kunye ne-workpiece ichaphazela ubuninzi bangoku.
