Nugget offset, inozivikanwawo sekuti nugget shift, idambudziko rinowanzo sangana mumatanho ekuisa welding. Inoreva kusarongeka kana kutamiswa kweiyo weld nugget kubva panzvimbo yayo yainotarirwa, izvo zvinogona kuguma nekushaya simba welds kana kukanganisa kubatana kutendeseka. Ichi chinyorwa chinopa mhinduro dzinoshanda kugadzirisa nyaya ye nugget offsets mune yepakati-frequency inverter spot welding michina.
- Yakakodzera Electrode Alignment: Nyaya: Kurongeka kusina kunaka kwe electrode kunogona kubatsira kune nugget offsets panguva yekuputika.
Solution: Ita shuwa kuti maelectrodes anoenderana nemazvo nemaworkpieces asati atanga basa rewelding. Tarisa kurongeka kwe electrode nguva dzose uye ita zvigadziriso sezvinodiwa. Kurongeka kwakakodzera kunovimbisa kuti simba rewelding rinogovaniswa zvakaenzana, zvichideredza mukana wekuti nugget offsets.
- Yakakwana Electrode Force: Nyaya: Kusakwana kwemagetsi emagetsi simba kunogona kutungamirira kune nugget offsets nekuda kwekusakwana kwekubatana kwekumanikidza pakati pe electrode uye workpieces.
Solution: Rongedza simba re electrode kusvika padanho rakakodzera zvichienderana nehupamhi hwezvinhu uye welding zvinodiwa. Iyo yakakurudzirwa simba yekumisikidza inogona kuwanikwa mumushini wemushandisi bhuku. Simba re electrode rakakwana rinobatsira kuchengetedza yakakodzera electrode-to-workpiece kuonana, kuderedza mikana ye nugget offsets.
- Optimal Welding Parameters: Nyaya: Zvisizvo zvigadziriso zvewelding, zvakadai sezvino, voltage, uye nguva yewelding, inogona kubatsira kune nugget offsets.
Solution: Optimize the welding parameters zvichienderana nerudzi rwezvinhu, ukobvu, uye dhizaini yakabatana. Kuitisa bvunzo welds kuona akakodzera parameter marongero anoburitsa anowirirana uye akatarisana weld nuggets. Kunyatsogadzirisa maparamendi ewelding kunoderedza nugget offsets uye inova nechokwadi chepamusoro-soro welds.
- Kugadzirira Kwakakodzera Kwekushanda: Nyaya: Kusakwana kwepamusoro kugadzirira kwezvishandiso zvinogona kutungamirira kune nugget offsets.
Sarudzo: Chenesa nzvimbo yebasa zvakakwana usati welding kuti ubvise chero tsvina, mafuta, kana mapeji anogona kuvhiringidza maitiro ekugadzira. Shandisa nzira dzakakodzera dzekuchenesa, dzakadai sekudzikisira kana kukuya pamusoro, kuve nechokwadi chenzvimbo yakachena uye yakafanana. Kugadzirira kwakakodzera workpiece kunosimudzira zvirinani electrode kusangana uye inoderedza njodzi ye nugget offset.
- Regular Electrode Maintenance: Nyaya: Akasakara kana akakuvadzwa maelectrode anogona kubatsira kune nugget offsets panguva yewelding.
Mhinduro: Ongorora ma electrode nguva nenguva uye woatsiva pazvinenge zvichidiwa. Chengetedza mazano e electrode akachena uye asina kupfeka zvakanyanya. Pamusoro pezvo, ita shuwa kuti zviso zve electrode zvakatsvedzerera uye hazvinei nekukanganisa kana deformation. Maelectrode akachengetwa zvakanaka anopa kuwirirana kunoenderana uye anovandudza weld mhando, kuderedza kuitika kwe nugget offsets.
Kugadzirisa nyaya ye nugget offsets mune yepakati-frequency inverter spot welding michina inoda kutarisisa kune akasiyana zvinhu, zvinosanganisira electrode alignment, electrode simba, welding paramita, workpiece kugadzirira, uye electrode kugadzirisa. Nekushandisa mhinduro dzakatsanangurwa muchinyorwa chino, vashandisi vanogona kuderedza nugget offsets, kusimudzira mhando yewelding, uye kuwana akavimbika uye akarongeka anonzwika weld majoini. Rangarira kutevedzera nhungamiro dzekuchengetedza uye tarisa bhuku remushandisi wemuchina kuti uwane mirairo uye kurudziro.
