Tsanangudzo yakadzama yeWelding Current Curve muMedium Frequency Inverter Spot Welding Machines.

Iyo welding yazvino curve inoita basa rakakosha muwelding process yepakati frequency inverter spot welding michina. Iyo inomiririra kusiyanisa kwe welding ikozvino nekufamba kwenguva uye ine yakakosha kukanganisa pamhando uye hunhu hweinoguma weld. Ichi chinyorwa chinopa tsananguro yakadzama yeiyo welding ikozvino curve mune yepakati frequency inverter spot welding michina.

1. Current Ramp-Up: Iyo welding yazvino curve inotanga ne ramp-up phase, apo welding ikozvino inowedzera zvishoma nezvishoma kubva pazero kuenda kune yakafanotemerwa kukosha. Ichi chikamu chinobvumira kugadzwa kwekugadzikana kwemagetsi kusangana pakati pe electrode uye workpieces. Iyo ramp-up nguva uye chiyero chinogona kugadziridzwa zvichienderana nechinhu, ukobvu, uye inodiwa welding paramita. Iyo inodzorwa uye yakatsetseka yazvino ramp-up inobatsira mukudzikisa spatter uye kuwana inowirirana weld nugget kuumbwa.
2. Welding Current Pulse: Kutevera ikozvino ramp-up, iyo welding ikozvino inopinda muchikamu chekupuruzira. Munguva yechikamu ichi, nguva inogara iripo inoshandiswa kwenguva yakati, inozivikanwa senguva yewelding. Iyo welding yazvino pulse inoburitsa kupisa panzvimbo dzekusangana, zvichikonzera kunyungudika kwenzvimbo uye kunotevera kusimba kuumba weld nugget. Kureba kweiyo welding ikozvino pulse inotarwa nezvinhu zvakaita semhando yezvinhu, ukobvu, uye inodiwa weld mhando. Kudzora kwakaringana kweye pulse nguva inovimbisa kukwana kwakaringana kwekupisa uye inodzivirira kupisa kana kudziyisa kweanoshanda.
3. Ikozvino Kuora: Mushure me welding ikozvino pulse, ikozvino zvishoma nezvishoma inoora kana kuderera kudzokera ku zero. Ichi chikamu chakakosha pakudzora kusimba uye kutonhora kweiyo weld nugget. Chiyero chekuora chazvino chinogona kugadziridzwa kuti chiwedzere kutonhora uye kudzivirira yakawandisa kupisa kupinza kunzvimbo dzakatenderedza, kuderedza kukanganisa uye kuchengetedza zvinhu zvezvinhu.
4. Post-Pulse Yazvino: Mune mamwe mawelding application, post-pulse ikozvino inoshandiswa mushure meiyo welding ikozvino pulse uye isati yaora yakazara yezvino. Iyo post-pulse ikozvino inobatsira mukunatsa iyo weld nugget uye kuvandudza ma mechanic zvimiro nekusimudzira solid-state diffusion uye kukwenenzvera zviyo. Kureba uye ukuru hweiyo post-pulse ikozvino inogona kugadziridzwa zvichibva pane chaiyo welding zvinodiwa.

Kunzwisisa iyo welding yazvino curve mune yepakati frequency inverter spot welding michina kwakakosha kuti uwane emhando yepamusoro uye akavimbika welds. Iyo inodzorwa ramp-up, welding ikozvino pulse, kuora kwazvino, uye inogona kushandiswa yepost-pulse ikozvino inobatsira kune yakazara welding process, kuve nechokwadi chekupisa kwakakodzera, kusimba, uye kutonhora. Nekugadzirisa iyo welding yazvino curve zvichibva pane zvinhu, ukobvu, uye yaidiwa weld hunhu, vagadziri vanogona kuwana inowirirana uye inogutsa mhedzisiro mune yavo spot welding application.
