Inkcazo enzulu ye-Welding Curve yangoku kwii-Medium Frequency Inverter Spot Welding Machines

Ijiko langoku le-welding lidlala indima ebalulekileyo kwinkqubo ye-welding yomatshini wokuwelda we-medium frequency inverter spot. Imele ukuhluka kwe-welding yangoku ngokuhamba kwexesha kwaye inempembelelo ebalulekileyo kumgangatho kunye neempawu ze-weld ezibangelwayo. Eli nqaku linika inkcazo eneenkcukacha ye-welding yangoku igophe kumatshini we-welding we-medium frequency inverter spot.

1. I-Ramp-Up yangoku: I-welding current curve iqala nge-ramp-up phase, apho i-welding current inyuka ngokuthe ngcembe ukusuka kwi-zero ukuya kwixabiso elimiselweyo. Esi sigaba sivumela ukusekwa koqhagamshelwano lombane oluzinzile phakathi kwe-electrodes kunye ne-workpieces. Ubude be-ramp-up kunye nesantya sinokuhlengahlengiswa ngokusekwe kwimathiriyeli, ubukhulu, kunye neeparamitha ze-welding ezifunwayo. Iramp-up yangoku elawulwayo negudileyo inceda ekunciphiseni ukutshiza kunye nokufezekisa ukwakheka kwe-weld nugget engaguqukiyo.
2. I-Welding Current Pulse: Ukulandela i-ramp-up yangoku, i-welding current ingena kwisigaba se-pulse. Ngethuba lesi sigaba, umbane oqhubekayo usetyenziswa ixesha elithile, elibizwa ngokuba lixesha le-welding. I-welding yangoku i-pulse ivelisa ubushushu kwiindawo zoqhagamshelwano, ezibangela ukunyibilika kwendawo kunye nokuqiniswa okulandelayo ukwenza i-weld nugget. Ubude bexesha le-welding yangoku i-pulse imiselwa yimiba efana nohlobo lwempahla, ubukhulu, kunye nomgangatho ofunekayo we-weld. Ukulawulwa ngokufanelekileyo kobude be-pulse kuqinisekisa igalelo elaneleyo lokushisa kwaye ugweme ukufudumala okanye ukufudumala kwezinto zokusebenza.
3. Ukubola kwangoku: Emva kwe-welding yangoku i-pulse, yangoku ngokuthe ngcembe ibola okanye iyancipha ibuyele kwi-zero. Esi sigaba sibalulekile ekuqiniseni okulawulwayo kunye nokupholisa i-weld nugget. Isantya sokubola kwangoku sinokuhlengahlengiswa ukuze kulungiswe izinga lokupholisa kunye nokuthintela igalelo lobushushu obugqithisileyo kwiindawo ezijikelezileyo, ukunciphisa ukuphazamiseka kunye nokugcinwa kwezinto eziphathekayo.
4. I-Post-Pulse yangoku: Kwezinye izicelo ze-welding, i-post-pulse current isetyenziswa emva kwe-welding current pulse nangaphambi kokubola okupheleleyo kwangoku. I-post-pulse current inceda ekucoceni i-weld nugget kunye nokuphucula iimpawu zayo zomatshini ngokukhuthaza ukusabalalisa kwe-slid-state kunye nokulungiswa kweenkozo. Ubude kunye nobukhulu be-post-pulse current bunokulungiswa ngokusekelwe kwiimfuno ezithile ze-welding.

Ukuqonda i-welding yangoku ijika kwi-medium frequency inverter spot welding machines kubalulekile ekufezekiseni i-welds ekumgangatho ophezulu kunye nethembekileyo. I-ramp-up elawulwayo, i-welding current pulse, ukubola kwangoku, kunye nokusetyenziswa okunokwenzeka kwe-post-pulse yangoku igalelo kwinkqubo ye-welding jikelele, ukuqinisekisa igalelo elifanelekileyo lokushisa, ukuqina, kunye nokupholisa. Ngokulungisa ijiko langoku le-welding ngokusekwe kwizinto eziphathekayo, ubukhulu, kunye neempawu ezinqwenelekayo ze-weld, abavelisi banokufikelela kwiziphumo ezingaguqukiyo nezanelisayo kwizicelo zabo zokuwelda.
