01.Inkcazo emfutshane
I-Spot welding yindlela yokumelana ne-welding apho iinxalenye ze-welding zidityaniswa kwi-lap joints kwaye zicinezelwe phakathi kwee-electrode ezimbini, usebenzisa ubushushu bokumelana nokunyibilikisa isiseko sesinyithi ukwenza i-solder joints.
I-Spot welding isetyenziswa kakhulu kule miba ilandelayo:
1. Ukudityaniswa kweendawo zokutsibela iipleyiti ezicekethekileyo, ezinje ngeekhabhi zemoto, iikhompatimenti, izikrini zokuvuna iintlanzi, njl.njl.
2. Ipleyiti encinci kunye nezakhiwo zentsimbi ezimile kunye nezakhiwo zesikhumba, ezifana neendonga ezisecaleni kunye neesilingi, iipaneli zokuthwala iinqwelwana, ukudibanisa iifuneli zokuvuna, njl.
3. Izikrini, iifreyimu zendawo kunye nemivalo yentsimbi enqamlezayo, njl.
02.Iimpawu
Ngexesha le-welding, i-weldment yenza i-joint edibeneyo kwaye icinezelwe phakathi kwee-electrode ezimbini. Iimpawu zayo eziphambili zezi zilandelayo:
1. Ngexesha lokutshisa indawo, ixesha lokufudumala kwendawo yokudibanisa lifutshane kakhulu kwaye isantya se-welding sikhawuleza.
2. I-Spot welding idla kuphela amandla ombane kwaye ayifuni izinto zokuzalisa, i-flux, igesi, njl.
3. Umgangatho wokuwelda indawo uqinisekiswa ikakhulu ngumatshini wokuwelda. Inomsebenzi olula, inqanaba eliphezulu lomatshini kunye ne-automation, kunye nemveliso ephezulu.
4. Amandla aphantsi abasebenzi kunye neemeko ezilungileyo zokusebenza.
5. Ekubeni i-welding igqityiwe ngexesha elifutshane kwaye idinga umbane omkhulu kunye noxinzelelo, ukulawulwa kwenkqubo yenkqubo kunzima ngakumbi, umatshini we-welding unomthamo omkhulu wombane, kwaye ixabiso lesixhobo liphezulu kakhulu.
6. Kunzima ukwenza uvavanyo olungonakaliyo lwamalungu e-solder.

03. Inkqubo yokusebenza
Ngaphambi kwe-welding, umphezulu we-workpiece kufuneka ucocwe. Unyango oluqhelekileyo lokucoca olusetyenziswayo luyi-pickling, oko kukuthi, i-pickled kuqala kwi-asidi ye-sulfuric evuthayo kunye ne-concentration ye-10%, kwaye ihlanjwe ngamanzi ashushu. Inkqubo ethile yokuwelda imi ngolu hlobo lulandelayo:
(1) Yondla i-workpiece edibeneyo phakathi kwee-electrode eziphezulu nangaphantsi zomatshini we-welding kwaye uyibambe;
(2) Xa umbane usetyenziswa, iindawo zokudityaniswa kwezinto ezimbini zokusebenza ziyafudunyezwa, zinyibilike ngokuyinxenye, kwaye kwenziwa i-nugget;
(3) Gcina uxinzelelo emva kokucima kombane, ukwenzela ukuba i-nugget etyhidiweyo iphole kwaye iqiniswe phantsi koxinzelelo ukwenza i-solder joints;
(4) Susa uxinzelelo kwaye ukhuphe i-workpiece.
04.Imiba enempembelelo
Izinto eziphambili ezichaphazela umgangatho we-welding ziquka i-welding yangoku kunye nexesha lokunika amandla, uxinzelelo lwe-electrode kunye ne-shunt, njl.
1. I-Welding yangoku kunye namandla-ngexesha
Ngokobukhulu be-welding yangoku kunye nobude bamandla-ngexesha, ukuwelda kwendawo kunokwahlulwa ibe ziindidi ezimbini: i-gauge enzima kunye ne-soft gauge. Inkcazo edlula umsinga omkhulu ngexesha elifutshane libizwa ngokuba yinkcazo enzima. Ineenzuzo zemveliso ephezulu, ubomi obude be-electrode, kunye ne-deformation encinci ye-weldment, kwaye ifanelekile kwiintsimbi ze-welding ezine-conductivity efanelekileyo ye-thermal. Igeyiji egqithisa umsinga omncinci kwixesha elide ibizwa ngokuba yigeji ethambileyo, enemveliso ephantsi kwaye ifanele ukuwelda iintsimbi ezithanda ukuqina.
2. Uxinzelelo lwe-electrode
Ngexesha le-welding yendawo, uxinzelelo olwenziwe kwi-weldment yi-electrode ibizwa ngokuba yi-electrode pressure. Uxinzelelo lwe-electrode kufuneka lukhethwe ngokufanelekileyo. Xa uxinzelelo luphezulu, i-shrinkage kunye ne-shrinkage cavities enokuthi yenzeke xa i-nugget iqina ingasuswa. Nangona kunjalo, ukuchasana kunye nokuxinana kwangoku kwe-electrode kuyancipha, okubangelwa ukufudumeza okwaneleyo kwe-weldment kunye nokunciphisa ububanzi be-nugget. Amandla okubambisana kwe-solder ayancipha. Ubungakanani boxinzelelo lwe-electrode bunokukhethwa ngokusekelwe kwezi zinto zilandelayo:
(1) Izinto ze-weldment. Ukuphakama kwamandla aphezulu obushushu bezinto eziphathekayo. Uxinzelelo olukhulu lwe-electrode olufunekayo. Ngoko ke, xa udiza intsimbi engatyiwayo kunye nentsimbi ekwaziyo ukumelana nobushushu, kufuneka kusetyenziswe uxinzelelo oluphezulu lwe-electrode kunaxa udityaniswa nentsimbi ephantsi yekhabhoni.
(2) Iiparamitha ze-Welding. Okukhona kunzima ukucaciswa kwe-welding, ngakumbi uxinzelelo lwe-electrode.
3. Ukuphazamiseka
Ngexesha le-welding yendawo, i-current flowing ngaphandle kwe-welding circuit i-welding ibizwa ngokuba yi-shunt. I-shunt inciphisa i-current ejikelezayo kwindawo ye-welding, okubangelwa ukufudumeza okunganeleyo, okubangela ukuncipha okukhulu kwamandla e-solder joint kunye nokuchaphazela umgangatho we-welding. Imiba echaphazela iqondo loluleko ikakhulu ibandakanya le miba ilandelayo:
(1) Ubukhulu be-weldment kunye neendawo zokubeka i-welding point. Njengoko umgama phakathi kwamalungu e-solder ukhula, ukuxhathisa kwe-shunt kuyanda kwaye iqondo lokunciphisa liyehla. Xa kusetyenziswa isithuba esiqhelekileyo se-30 ukuya kwi-50 mm, i-shunt yangoku i-akhawunti ye-25% ukuya kwi-40% yangoku iyonke, kwaye njengoko ubukhulu be-weldment buyancipha, i-degree of shunting nayo iyancipha.
(2) Ubume bomphezulu we-weldment. Xa kukho i-oxides okanye ukungcola ebusweni be-weldment, ukuchasana koqhagamshelwano phakathi kwee-weldments ezimbini kwanda, kwaye i-current passing kwindawo ye-welding iyancipha, oko kukuthi, i-degree of shunting iyanda. I-workpiece ingakhethwa, ifakwe isanti okanye ipolishwe.
05.Amanyathelo okhuseleko
(1) Ukutshintshwa kweenyawo zomatshini we-welding kufuneka kube nesikhuselo esinamandla sokukhusela ukuthintela ukusebenza ngengozi.
(2) Indawo ekusetyenzwa kuyo ifanele ixhotyiswe ngeebhaffles zokuthintela iintlantsi ezisebenzayo ukuba zibhabhe.
(3) Abashicileli bafanele banxibe iindondo ezisicaba zokuzikhusela xa bewelda.
(4) Indawo apho umatshini wokuwelda ubekwe khona kufuneka igcinwe yomile, kwaye umgangatho kufuneka ugalelwe iipleyiti ezichasene ne-skid.
(5) Emva kokuba umsebenzi we-welding ugqityiwe, umbane kufuneka ucinywe, kwaye ukutshintshwa kwamanzi okupholisa kufuneka kwandiswe imizuzwana ye-10 ngaphambi kokuvala. Xa iqondo lobushushu lisezantsi, amanzi aqokelelweyo kumzila wamanzi kufuneka asuswe ukuze kuthintelwe umkhenkce.
