Uhlalutyo lweMathiriyeli ye-Electrode ye-Resistance Spot Welding Machines

I-Resistance spot welding yindlela esetyenziswa ngokubanzi kwishishini lemveliso, esetyenziselwa ukudibanisa amashidi 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 ukushisa okufunekayo 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. I-Tungsten 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 nokuchasana kombane. 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. Iingubo ze-Electrode

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.
