Iwe unoziva here matanho mangani akabatanidzwa muwelding process yepakati frequency spot welding michina?Nhasi, mupepeti anokupa sumo yakadzama kune welding maitiro epakati frequency nzvimbo welding muchina.Mushure mekufamba nematanho akati wandei, ndiko kutenderera kutenderera kwepakati frequency nzvimbo welding muchina.
1. Ita preloading preloading simba risati ratanga.
Chinangwa cheiyo preloading nguva ndeyekuita hukama hwepedyo pakati pezvikamu zvakashongedzwa, zvichikonzera deformation yepurasitiki yezvikamu zvakabudikira pane yakasangana, kukuvadza iyo oxide firimu pamusoro, uye kugadzira yakagadzikana yekubata kuramba.Kana dzvinyiriro yakadzikira, zvikamu zvishoma chete zvakabudikira zvinogona kuita mahwekwe, zvichigadzira kupikisa kukuru.Kubva pane izvi, simbi ichakurumidza kunyunguduka panzvimbo yekusangana, ichiputika kunze kwemhando yemoto, uye mumatambudziko akaoma, chikamu chakasungirirwa kana electrode inogona kupiswa.Nekuda kwehupamhi uye kukwirira kwemaitiro kuomarara kwezvikamu zvakashongedzwa, kunaka kwepamusoro kwezvikamu zvakashongedzwa hazvina kunaka.Naizvozvo, kuitira kuti zvidimbu zvakashongedzwa zvibatane zvakanyanya uye kudzikamisa kushorwa kwenzvimbo yewelding, yakawedzera ikozvino inogona kuwedzerwa panguva ye pre pressing stage kana panguva ye pre pressing stage.Panguva ino, pre-pressing pressure inowanzoita 0.5-1.5 times the normal pressure, uye imwe yazvino ndeye 1/4-12 yewelding current.
2. Kuita kupisa kwemagetsi.
Mushure mekutanga kudzvanya, zvikamu zvakasungwa zvinogona kusungirirwa zvakasimba.Kana iyo welding parameter yakwana, simbi inogara ichitanga kunyunguduka pane yekubata kumeso pakati pezvikamu zviviri zvakashongedzwa panzvimbo ye electrode clamping, pasina kuwedzera, zvishoma nezvishoma ichigadzira nucleus yakanyungudutswa.Pasi pekumanikidzwa panguva yewelding, iyo nucleus yakanyungudutswa inopenya (panguva yewelding), ichigadzira chisungo chakasimba pakati pezvikamu zviviri zvakasungwa.
3. Kufemba nekutsikirira.
Iyi nhanho inozivikanwa zvakare seyekutonhodza crystallization nhanho, zvinoreva kuti mushure mekunge iyo yakanyungudutswa yasvika pachimiro uye saizi yakakodzera, ikozvino welding inogurwa, uye iyo yakanyungudutswa yepakati inotonhorera uye crystallizes pasi pekumanikidzwa.Iyo yakanyungudutswa yakakosha crystallization inoitika muyakavharwa simbi firimu uye haigone kubvumirana zvakasununguka panguva yecrystallization.Nekushandisa nzira iyi, simbi dzakacheneswa dzinogona kusunganidzwa pamwe chete pasina kana shrinkage kana kuputika, zvichibvumira simbi yakanyungudutswa kupenya zvachose isati yamira kushandiswa.
