Ukukhetha izixhobo ze-Electrode zoomatshini bokuwelda beNdawo ePhakathi?

Ukukhetha izinto ezifanelekileyo ze-electrode sisigqibo esibalulekileyo ekuqinisekiseni ukusebenza kunye nokuqina koomatshini be-welding spot welding. Eli nqaku lixubusha izinto ezinokuthi ziqwalaselwe xa ukhetha izinto ze-electrode kwaye zibonelela ngengqiqo kwinkqubo yokukhetha.

1. Ukuhambelana kwezinto eziphathekayo:Izinto ze-electrode kufuneka zihambelane nezinto ezixutywayo. Kubalulekile ukuqwalasela izinto ezinje nge-conductivity, ukwanda kwe-thermal, kunye nokuphinda kusebenze iikhemikhali ukuthintela ukuhanjiswa kwezinto kunye nokungcoliseka ngexesha le-welding.
2. I-Electrode Wear Resistance:Khetha izinto ezinokumelana nokunxiba okuphezulu ukumelana noxinzelelo lomatshini kunye nobushushu obufunyenwe ngexesha lomsebenzi we-welding. Izinto ezinje ngeealloyi zethusi, ubhedu lwechromium, kunye neentsimbi eziphikisayo zaziwa ngokuxhathisa kwazo.
3. Ukuxhathisa ubushushu kunye nokuqhuba kweThermal:Ii-Electrodes kufuneka zibe nokumelana kakuhle nobushushu ukuthintela ukuguquka kwangaphambi kwexesha okanye ukunyibilika ngexesha lokuwelda. Ukongezelela, umgangatho ofanelekileyo we-thermal conductivity unceda ekukhupheni ngokufanelekileyo ukushisa okwenziwa ngexesha lenkqubo ye-welding.
4. Ukuqhutywa koMbane:Ukuhanjiswa kombane okuphezulu kubalulekile ekugqithiseni amandla ngokufanelekileyo ukusuka kumatshini wokuwelda ukuya kwindawo yokusebenza. I-Copper kunye ne-alloys yayo, ngenxa ye-conductivity egqwesileyo, isetyenziswa ngokuqhelekileyo izinto ze-electrode.
5. Ukuxhathisa ukonakala:Qwalasela indawo ye-welding ukukhetha izinto ezinikezela ukuchasana kokubola okwaneleyo. Oku kubaluleke ngakumbi xa kusetyenzwa ngemathiriyeli esengozini yokubola okanye kwiimeko ezifumileyo.
6. Iindleko kunye nokufumaneka:Ukulungelelanisa ukusebenza kunye neendleko kubalulekile. Ngelixa izinto ezifana ne-tungsten yethusi zibonelela ngeempawu ezikhethekileyo, zinokubiza ngakumbi. Ukuvavanya iimfuno ze-welding kunye nokunyanzeliswa kwebhajethi xa ukhetha izinto ze-electrode.
7. Ukugqitywa komphezulu kunye noKwaleka:Ezinye izicelo zixhamla kwiingubo ze-electrode eziphakamisa ukuxhathisa ukunxiba, ukuthintela ukuncamathela, okanye ukunciphisa isipatter. Iingubo ezifana ne-chrome plating okanye i-electrode dressing inokwandisa ubomi bokusebenza kwe-electrode.

Ukukhetha izixhobo ze-Electrode:

1. Iingxube zeCopper kunye neCopper:Ezi zisetyenziselwa ngokubanzi ukuhanjiswa kombane okugqwesileyo, ukuhanjiswa kakuhle kwe-thermal, kunye nokumelana nokunxiba. I-alloys efana neClass 2 (C18200) kunye neClass 3 (C18150) i-alloys zethusi zikhetho eziqhelekileyo.
2. Ubhedu lweChromium:I-Chromium copper alloys (CuCrZr) inikezela ukumelana nokunxiba okuphezulu, ukuhanjiswa kombane okulungileyo, kunye nokuzinza kwe-thermal. Zifanelekele izicelo ze-welding ezifunayo.
3. I-Tungsten-Copper Alloys:I-electrodes ye-tungsten-copper idibanisa iimpawu ze-tungsten ephezulu yokunyibilika kunye ne-copper conductivity. Zifanelekile kwizicelo ezifuna ukuchasana nobushushu obuphezulu.
4. I-Molybdenum:Ii-electrode ze-Molybdenum zisetyenziselwa izicelo ezikhethekileyo ezifuna ukumelana nobushushu obuphezulu kunye nokwandiswa kwe-thermal ephantsi.

Ukukhethwa kwezinto ze-electrode kumatshini wokuwelda amabala aphakathi kuxhomekeke kwizinto ezahlukeneyo, kubandakanya ukuhambelana nezixhobo zokusebenza, ukumelana nokunxiba, ukumelana nobushushu, ukuqhutywa kombane, kunye neendleko. Ngokuphonononga ngononophelo ezi zinto kunye nokuqonda iimfuno ezithile ze-welding, abavelisi banokukhetha izinto ezifanelekileyo ze-electrode ezinegalelo ekusebenzeni ngokufanelekileyo kunye nomgangatho ophezulu we-welding.
