Bakin Karfe Welding Electrode AWS E308-16 (A102)
APPLICATIONS:
Ana iya amfani da ga lalata juriya na bakin karfe tsarin, kamar 06Cr19Ni9 da 06Cr19Ni11Ti, wanda aiki zafin jiki a kasa 300 ℃;Hakanan za'a iya amfani dashi don tsarin bakin karfe ta amfani da yanayin yanayin zafi na cryogenic, kamar akwati na ruwa na nitrogen, kwantena masu ruwa da ruwa, da dai sauransu.
HALAYE:
E308-16wani nau'in rutile ne mai rufi Cr18Ni9 bakin karfe.Dukansu AC da DC za a iya amfani da su kuma za su iya zama duk-wuri waldi.Zai iya kaiwa kyakkyawan aikin walda, barga baka, ƙaramin spatter, sauƙin cire slag da bayyanar walda mai kyau.Ƙarfin da aka ajiye yana da kyakkyawan juriya ga lalatawar ɓangarorin ɓangarorin.
HANKALI:
1. Dole ne a toya na'urorin lantarki da 320-350 ℃ na awa 1 kafin waldawa, bushe wutar lantarki lokacin amfani da shi.
2. Tsatsa, mai, ruwa da sauran dattin walda dole ne a cire kafin walda.
3.Recommended DC wutar lantarki, saboda AC waldi yana da m shigar azzakari cikin farji, halin yanzu kada ya zama ma girma, domin kauce wa shafi redness da fatattaka.
4. Don rage girman shigarwar zafi dawalda lantarkiamplitude oscillating kada yayi girma da yawa.
5. Preheat da interlayer-zazzabi ya kamata su kasance ƙasa da 150 ℃

Ƙirƙirar sassan sassa na walda za su bi tsari, takaddun tsari da tanadin wannan ma'auni.3.2 Abubuwan buƙatu don zafin yanayi yayin samar da walda:
Lokacin da aka gyara sassa da ƙãre kayayyakin, zafin jiki kada ya zama ƙasa da masu zuwa:
Low carbon karfe abu: -20 ℃;
Low gami tsarin karfe abu: -15 ℃.
Gabaɗaya, zafin zafin waldi da aka halatta na sassan walda yakamata ya dace da buƙatun Tebur.
Lokacin da sassa na walda ke waldawa a ƙarƙashin ƙananan yanayin zafi (kamar yadda aka jera a cikin Tebur 1), saman karfe ya kamata a riga ya yi zafi.Nisa na yankin preheating dole ne ya zama fiye da sau 4 na kauri na farantin da za a yi walda, kuma nisa preheating a kowane gefe kada ya zama ƙasa da 100mm.Welding za a iya yi kawai bayan dumama zuwa 100 ~ ~ 200 ℃.Idan ana amfani da preheating na harshen wuta, nisa tsakanin ginshiƙin harshen wuta da saman allo ya kamata ya fi 50mm.
A karkashin al'ada zazzabi yanayi, domin waldi sassa da high rigidity da matalauta weldability, preheating ya kamata kuma a za'ayi kafin waldi (da preheating zafin jiki ne a cikin kewayon 100 ~ 200 ℃), da zafi adana ko tempering ya kamata a za'ayi bayan waldi zuwa kawar waldi danniya.
