Resistance spot welding inzira inoshandiswa zvakanyanya yekubatanidza mukugadzira, uye iyo pre-welding nguva ndiyo yakakosha paramende inogona kukanganisa zvakanyanya kunaka kweiyo weld. Muchikamu chino, isu tichakurukura maitiro ekugadzirisa iyo pre-welding nguva yekupikisa nzvimbo welding muchina kuti uwane mhedzisiro yakanaka.
Kunzwisisa Pre-welding Nguva:
Usati wanyura mukati mekugadzirisa maitiro, zvakakosha kuti unzwisise kuti pre-welding nguva ndeyei uye nei ichikosha. Pre-welding nguva, inozivikanwawo sekuti kusvina nguva kana kubata nguva, ndiyo nguva iyo welding electrodes iri kusangana neanoshanda basa risati raiswa welding chaiyo. Iyi nguva inobvumira ma electrode kuti aite kumanikidza pane workpieces, kugadzira yakasimba yakabatana interface uye kubvisa chero kusvibiswa kwepamusoro, kuve nechokwadi chesimba uye rakavimbika weld.
Zvinhu Zvinokonzera Pre-welding Nguva:
Zvinhu zvakati wandei zvinogona kukanganisa iyo yakakodzera pre-welding nguva yeakapihwa welding application:
- Rudzi rwezvinhu:Zvinhu zvakasiyana-siyana zvine maitiro akasiyana-siyana ekupisa uye magetsi ekudzivirira. Nekuda kweizvozvo, ivo vangangoda dzakasiyana pre-welding nguva kuti uwane inodiwa weld mhando.
- Hukuru hwezvinhu:Zvishongo zvakakora zvinowanzoda nguva refu-yekutanga-welding kuti ive nechokwadi chekudziya kwakakodzera uye kuyerera kwezvinhu.
- Electrode Force:Simba rinoshandiswa nema electrode welding rinoita basa rakakosha pakuona inodiwa pre-welding nguva. Masimba epamusoro anogona kuda nguva refu isati yave welding.
- Electrode Geometry:Chimiro uye saizi yemagetsi emagetsi anogona kukanganisa kugoverwa kwekumanikidza uye ikozvino, izvo zvinogona, zvakare, kukanganisa inodiwa pre-welding nguva.
Kugadzirisa Pre-welding Nguva:
Kuti ugadzirise iyo pre-welding nguva yekupikisa nzvimbo welding muchina, tevera matanho aya:
- Nzwisisa Zvishandiso Zvako:Ziva rudzi uye ukobvu hwezvinhu zvauri welding. Tarisa kune welding nhungamiro kana kuonana nenyanzvi dzezvinhu kana zvichidikanwa.
- Funga nezveElectrode Force:Iva nechokwadi chokuti simba re electrode rakagadzirirwa zvakakodzera. Kana simba racho rakanyanya kuderera, iwe ungada kuwedzera pre-welding nguva kubhadhara kusakwana kudzvinyirira.
- Kuedza:Zvinowanzodikanwa kuitisa nhevedzano yebvunzo welds neakasiyana pre-welding nguva kuti uwane iyo yakakwana nguva yechishandiso chako chaicho.
- Ongorora Weld Hunhu:Mushure memuyedzo wega wega weld, nyatsoongorora iyo weld mhando. Tarisa zviratidzo zvekusakwana fusion, yakawandisa spatter, kana kumwe kukanganisa. Iyo yakakodzera pre-welding nguva inofanirwa kuguma nekuenderana, yemhando yepamusoro weld.
- Rekodha Zvawanikwa:Chengetedza rekodhi yenguva dzepre-welding dzinoshandiswa pabvunzo yega yega, pamwe chete nehunoenderana weld quality. Iyi data ichakubatsira iwe kuona yakanakisa pre-welding nguva yemangwana welds.
- Kunyatsogadzirisa:Ramba uchigadzirisa uye gadzirisa iyo pre-welding nguva kusvika iwe wagara wawana yaunoda weld mhando.
Kugadzirisa iyo pre-welding nguva yekupikisa nzvimbo welding muchina inhanho yakakosha mukuwana emhando yepamusoro welds. Nekufunga zvivakwa zvezvinhu, simba re electrode, uye kuita kuyedza kwakarongeka, unogona kuwana iyo yakakwana pre-welding nguva yeiyo yako chaiyo welding application. Uku kutarisisa kune zvakadzama kunoguma nekusimba, kwakavimbika welds uye nekuvandudzwa kwese kwekugadzira kunyatsoita.
