Me yasa Waya Copper Spot Welding Yana Bukatar Zaɓin Electrode na Musamman
Copper yana da ƙarfin lantarki da ƙarfin zafi sosai. Duk da yake wannan yana da fa'ida a aikace-aikacen lantarki, yana haifar da ƙalubale a cikin walda:
- High conductivity + m zafi watsawa: Makamashi da sauri ya bazu daga wurin walda, yana sa ya zama da wahala a cimma daidaitaccen haɗuwa.
- Oxidation da adhesion matsaloli: Copper yana sauƙaƙe oxidizes a ƙarƙashin babban zafin jiki kuma yana manne da lantarki, yana haifar da lalacewa da sauri da ingancin walda mara ƙarfi.
- High inji da thermal danniya: A lokacin waldawar tabo, na'urorin lantarki dole ne su yi tsayin daka, tasiri na yanzu, da kuma sake zagayowar zafi.
Don haka, dole ne kayan lantarki su samar da ƙarfin aiki mai ƙarfi, ɗorewa, juriya na zafi, da aikin mannewa don tabbatar da ingancin walda, ƙarfin walda, da tsawon kayan aiki.
Injin Welding Spot don Copper - MFDC & Capacitor Discharge Welders
A cikin masana'anta na zamani, ana amfani da nau'ikan kayan aiki iri biyu don walda wayar tagulla:
Samar da ingantaccen fitarwa na halin yanzu mai ƙarfi. Mafi dacewa don aikace-aikacen da ke buƙatar daidaiton ingancin walda.
Saki babban halin yanzu a cikin ɗan ƙanƙanin lokaci, manufa don sirararan wayoyi na jan karfe da samar da sauri mai sarrafa kansa-.
Ko da kuwa nau'in injin, zaɓin lantarki dole ne ya dace da kayan da aikace-aikace.
Abubuwan Electrode da Yanayin Aikace-aikace
| Electrode Material | Mabuɗin Siffofin | Shawarar Amfani / Kauri na Tagulla | Saitunan Injin da aka Shawarta |

Daidaita siga na daidai yana da mahimmanci don cimma ingantaccen ingancin walda:
1. Yanzu da Lokacin Walda
- Ƙananan wayoyi na jan karfe: Yi amfani da gajeriyar bugun jini (0.1-0.3 s) don rage zafi.
- Matsakaici/kauri sassa: Ƙara halin yanzu, ƙara lokacin walda, ko amfani da jeri na bugun jini da yawa.
2. Matsalolin Electrode
- Ƙananan wayoyi: kimanin.0.3 MPa
- Sassan jan karfe mai kauri:0.5 MPa ko mafi girma
3. Bukatun sanyaya
- KulaYafi ko daidaita 60 l/minkwararar sanyaya don C18150, CuW, da OD{1}}Cu electrodes.
- Hana zafi fiye da kima, nakasawa, da saurin lalacewa.
4. Kulawa na yau da kullun
- Sauya na'urorin lantarki lokacin da diamita na tip ya ragu daYafi ko daidai da 20%.
- Tsaftace saman lantarki akai-akai don cire oxidation da ajiyar tagulla.
- Yi amfani da saka idanu na PLC don halin yanzu, matsa lamba, da kwanciyar hankali.
Yadda Kayayyakin Electrode ke Shafi Inganci da Rayuwar Kayan aiki
- High conductivity → mafi kyawun canja wurin makamashi
- Sa juriya → tsawon rayuwar lantarki da ƙarancin maye
- Juriya mai zafi → daidaitaccen ƙirar walda nugget
- Anti{0}}adhesion → ƙarancin gurɓatacce da ingantaccen walda
Zaɓin madaidaicin na'urar lantarki yana rage sauye-sauye sosai, yana inganta daidaiton walda, kuma yana rage farashin samarwa.
Jagorar Zaɓin Electrode mai sauri
- Siraren wayoyi na jan karfe (1-2 mm) → Tsabtace Tagulla
- Matsakaicin -ƙarar jan karfe (3-6 mm) → C18150
- Ƙaƙƙarfan sassan jan karfe (Mafi girma ko daidai da 5 mm) → CuW70 / CuW80
- Daidaitacce ko anti{0}} aikace-aikacen mannewa → OD-Cu
Kuskuren gama gari don gujewa
- "Higher conductivity ne ko da yaushe mafi alhẽri."
Tagulla mai tsafta yana aiki da kyau amma yana sawa da sauri -wanda bai dace da babban walda ba{1}.
- "Electrodes baya buƙatar kulawa."
Lalacewar Electrode, oxidation, da nakasawa babu makawa.
- "Ma'auni ɗaya ya dace da duk waldi na jan karfe."
Kowane kauri da aikace-aikace na bukatar musamman waldi sigogi.
