Intshayelelo yokuWelding, Uxinzelelo lwangaphambili, kunye nokubamba ixesha kwiMedium-Frequency Inverter Spot Welding Machines

Oomatshini bokuwelda bamabala aphakathi-frequency inverter basetyenziswa kakhulu kumashishini ahlukeneyo ukuze bakwazi ukuvelisa iiwelds ezinamandla nezithembekileyo. Ukuqinisekisa umgangatho we-weld ogqwesileyo kunye nokusebenza, kubalulekile ukuqonda iikhonsepthi zokuwelda, uxinzelelo lwangaphambili, kunye nokubamba ixesha kwaba matshini. Eli nqaku libonelela ngamagqabantshintshi welding, pre-uxinzelelo, kwaye ubambe ixesha medium-frequency inverter spot oomatshini welding.

1. I-Welding: I-Welding yinkqubo yokuqala apho iziqwenga zentsimbi ezimbini okanye ngaphezulu zidityaniswa kusetyenziswa ubushushu kunye noxinzelelo. Kwi-medium-frequency inverter spot welding machines, inkqubo ye-welding ibandakanya ukudlula i-current high through workpieces ukuvelisa ubushushu kwindawo yoqhagamshelwano. Ubushushu bubangela ukuba intsimbi inyibilike kwaye yenze i-weld nugget, ethi iqine xa iphola. I-weld nugget inika amandla kunye nokunyaniseka kokudibanisa.
2. Uxinzelelo lwangaphambili: Uxinzelelo lwangaphambili, olukwabizwa ngokuba yi-squeeze okanye i-electrode force, ibhekiselele kuxinzelelo lokuqala olusetyenziswe kwizinto zokusebenza ngaphambi kokuba i-welding current isebenze. Uxinzelelo lwangaphambili luyimfuneko ekuqinisekiseni uqhagamshelwano olufanelekileyo kunye nokulungelelaniswa phakathi kwezinto zokusebenza kunye nee-electrode. Inceda ukuphelisa naziphi na izikhewu okanye ukungahambi kakuhle okunokuchaphazela umgangatho we-weld. Amandla oxinzelelo lwangaphambili kufuneka abe ngokwaneleyo ukuseka uqhagamshelwano oluzinzileyo ngaphandle kokubangela ukuguqulwa okugqithisileyo okanye umonakalo kwizinto zokusebenza.
3. Ixesha lokubamba: Ixesha lokubamba, elikwabizwa ngokuba lixesha le-welding okanye ixesha le-nugget, lixesha apho i-welding current igcinwa khona emva kwesigaba sangaphambili soxinzelelo. Ixesha lokubamba livumela ubushushu ukuba busasazeke ngokulinganayo kwaye buququzelele ukubunjwa kwe-weld nugget ephuhliswe kakuhle kwaye eyomeleleyo. Ubude bexesha lokubamba buxhomekeke kwizinto ezifana nesixhobo sokusebenza, ubukhulu, i-welding yangoku, kunye nomgangatho ofunekayo we-weld. Kubalulekile ukumisela elona xesha lifanelekileyo lokubamba ukufezekisa iiwelds ezingaguqukiyo nezithembekileyo.

I-Welding, i-pre-pressure, kunye nexesha lokubamba zizinto ezibaluleke kakhulu ekusebenzeni koomatshini be-inverter spot welding ephakathi. Ukuqonda imigaqo emva kwezi nkqubo kubalulekile ekufezekiseni i-welds ekumgangatho ophezulu ngamandla afanelekileyo kunye nokunyaniseka. Ngokulungisa iiparitha ze-welding, kubandakanywa amandla angaphambili kunye nokubamba ixesha, abaqhubi banokuqinisekisa i-welds ethembekileyo kunye ehambelanayo kwizicelo ezahlukeneyo.
