Uhlalutyo lweMathiriyeli ye-Electrode ye-Resistance Spot Welding Machines

I-Resistance spot welding yindlela esetyenziswa ngokubanzi kwishishini lemveliso, esetyenziselwa ukudibanisa amashiti esinyithi ngokwenza umbane wendawo kwindawo ye-weld point.Ukukhethwa kwezinto ze-electrode kudlala indima ebalulekileyo kwinkqubo ye-welding, izinto ezichaphazelayo ezifana nomgangatho we-weld, ukuqina, kunye neendleko-zokusebenza.

1. Ii-Electrodes zobhedu

I-electrode yobhedu yenye yezona zinto ziqhelekileyo zokukhetha koomatshini bokuwelda bamabala.Baziwa ngokugqwesa kwe-thermal kunye ne-electrical conductivity, enceda ekuveliseni ubushushu obufunekayo kwi-welding.Ii-electrode zobhedu nazo zibonelela ngokuzinzileyo kwaye zinokumelana namaqondo obushushu aphezulu.Nangona kunjalo, badla ngokuphelelwa lixesha kwaye banokufuna ukutshintshwa rhoqo okanye ukulungiswa.

2. IiTungsten Electrodes

I-electrodes ye-Tungsten yenye inketho yokumelana nendawo yokuwelda.Zinendawo ephezulu yokunyibilika kunye ne-conductivity egqwesileyo yombane, ezenza zilungele izicelo ze-welding ezibandakanya ukushisa okuphezulu kunye nokumelana nombane.Ii-electrode zeTungsten ziyaziwa ngokuphila ixesha elide, kodwa zinokubiza kakhulu ngaphambili xa kuthelekiswa nee-electrode zobhedu.

3. I-Refractory Metal Alloys

Ezinye iindawo ezixhathisayo zokuwelda zifuna iindawo eziphezulu zokunyibilika kunye nokuqina kunokuba i-tungsten inokubonelela.Kwiimeko ezinjalo, i-alloys yensimbi ephikisayo efana ne-molybdenum kunye ne-tantalum isetyenziswa.Ezi zixhobo zinika ukuxhathisa okukhethekileyo kubushushu kunye nomhlwa, zizenza zilungele imisebenzi ye-welding ekhethekileyo.Nangona kunjalo, iindleko zabo eziphezulu zinokuba yinto ethintela usetyenziso olubanzi.

4. Ii-Electrode ezihlanganisiweyo

I-electrodes edibeneyo idibanisa izinto ezahlukeneyo ukuphumeza ukulinganisela kweempawu.Ngokomzekelo, i-electrode ye-copper-tungsten composite idibanisa i-conductivity egqwesileyo yobhedu kunye nokumelana nokushisa okuphezulu kwe-tungsten.Ezi electrode zinika ulungelelwaniso phakathi kweendleko kunye nokusebenza, okwenza kube lukhetho oludumileyo kwizicelo ezininzi ze-welding.

5. Ii-Electrode Coatings

Kwezinye iimeko, ii-electrodes zigqunywe ngezinto ezifana ne-chromium okanye i-zirconium ukuphucula ukuxhathisa ukunxiba kunye nokubola.Ezi zambatho zinokukwandisa ixesha lokuphila kwe-electrode kunye nokuphucula umgangatho we-weld.

Ukuqukumbela, ukhetho lwezixhobo ze-electrode zokumelana noomatshini bokuwelda kuxhomekeke kwizinto ezahlukeneyo, kubandakanya nesicelo sokuwelda, ukuqwalaselwa kweendleko, kunye neempawu zokusebenza ezifunwayo.I-Copper, i-tungsten, i-alloys yensimbi ekhanyelayo, izinto ezidibeneyo, kunye ne-electrode coatings zonke zineengenelo kunye nemida yazo.Iinjineli kunye ne-welders kufuneka zivavanye ngokucophelela ezi zinto ukuze zikhethe ezona zinto zifanelekileyo ze-electrode kwiimfuno zabo, ekugqibeleni ziqinisekise impumelelo yenkqubo ye-welding.
