Zvinokonzera Electrode Kunamira Phenomenon muMedium-Frequency Inverter Spot Welding yeGalvanized Simbi Sheets?

Mashizha esimbi ane galvanized anowanzo shandiswa mumaindasitiri akasiyana siyana nekuda kwekunaka kwawo kwegora. Nekudaro, kana welding galvanized simbi uchishandisa yepakati-frequency inverter spot welding muchina, chiitiko chinonzi electrode sticking chinogona kuitika. Ichi chinyorwa chine chinangwa chekuongorora zvikonzero zvekunamira kwe electrode mukati me-frequency inverter spot welding yemarata ane galvanized simbi uye kupa ruzivo rwekurerutsa nyaya iyi.

1. Zinc Vapor uye Kusvibiswa: Chimwe chezvikonzero zvakakosha zvekunamira kwe electrode muwelding galvanized steel sheets ndiko kuburitswa kwe zinc vapor panguva yewelding. Iyo tembiricha yakakwira inogadzirwa panguva yewelding inogona kunyungudutsa zinc coating, iyo inobva yanamira uye inonamatira kune electrode nzvimbo. Iyi zinc kusvibiswa inoumba dhizaini inoita kuti maelectrodes anamate kune workpiece, zvichikonzera kunetsa mukuparadzaniswa kwe electrode.
2. Kuumbwa kweZinc Oxide: Kana iyo zinc mhute inoburitswa panguva yekupisa inosangana nemhepo yemhepo, inoumba zinc oxide. Kuvepo kwe zinc oxide panzvimbo ye electrode kunowedzera nyaya yekunamatira. Zinc oxide ine zvimiro zvekunamatira, zvichibatsira mukunamira pakati pe electrode uye galvanized simbi sheet.
3. Electrode Material uye Coating: Sarudzo ye electrode zvinhu uye coating inogonawo kukanganisa kuitika kwekunamira kwe electrode. Zvimwe zvemagetsi emagetsi kana machira anogona kunge ane hukama hwepamusoro kune zinc, zvichiwedzera mukana wekunamira. Semuenzaniso, maelectrodes ane copper-based composition anowanzo kunamatira nekuda kwehukama hwayo hwepamusoro kune zinc.
4. Kusakwana Electrode Kutonhodza: ​​Kusakwana electrode kutonhora kunogona kuita kuti electrode inamira. Welding mashandiro anoita kupisa kwakanyanya, uye pasina nzira dzekutonhodza dzakafanira, maelectrode anogona kupisa zvakanyanya. Iyo tembiricha yakakwira inosimudzira kunamatira zinc mhute uye zinc oxide kune electrode nzvimbo, zvichikonzera kunamira.

Mitigation Strategies: Kudzikisira kana kudzivirira electrode kunamatira kana welding galvanized steel sheets ane medium-frequency inverter spot welding muchina, akati wandei anogona kushandiswa:

1. Electrode Kupfeka: Kugara uchipfeka emagetsi kwakakosha kubvisa zinc kuvaka uye kuchengetedza yakachena electrode nzvimbo. Kugadziriswa kwe electrode kwakakodzera kunobatsira kudzivirira kuunganidza zinc vapor uye zinc oxide, kuderedza kuitika kwekunamatira.
2. Electrode Coating Selection: Kusarudza ma electrode coatings ane low affinity ye zinc anogona kubatsira kuderedza kunamatira. Mabatiro ane anti-stick zvivakwa kana machira akagadzirirwa chaizvo kusungirira galvanized simbi anogona kutariswa.
3. Kutonhodza Kwakaringana: Kuve nechokwadi chekutonhodza kwakakwana kwemagetsi panguva yewelding kwakakosha. Maitiro ekutonhodza akakodzera, akadai sekutonhodza kwemvura, anogona kunyatso bvisa kupisa uye kudzivirira yakawandisa tembiricha ye electrode, kuderedza mukana wekunamira.
4. Optimization of Welding Parameters: Fine-tuning welding parameters, seazvino, welding time, uye electrode force, inogona kubatsira kuderedza kunamatira. Nekutsvaga iyo yakakwana parameter marongero, iyo welding process inogona kugadzirwa kuti ideredze zinc vaporization uye kunamatira.

Kuitika kweelectrode inonamira mukati me-frequency inverter spot welding yemarata esimbi inonyanya kukonzerwa nekuburitswa kwe zinc mhute, kuumbwa kwezinc oxide, electrode zvinhu uye coating factor, uye kusakwana electrode kutonhora. Nekushandisa nzira dzakaita seyenguva dzose kupfeka electrode, kusarudza akakodzera emagetsi emagetsi, kuve nechokwadi chekutonhodza kwakakwana, uye nekugadzirisa maparamendi ewelding, nyaya yekunamira inogona kudzikiswa. Matanho aya anozobatsira mukutsetseka kwekushanda kwewelding, kuvandudzwa kwechigadzirwa, uye emhando yepamusoro welds kana uchishanda nemarata ane galvanized simbi.
