Bakin Karfe Welding Electrode AWS E310-16 (A402)

APPLICATIONS:

Ana amfani da shi don walda irin nau'in bakin karfe mai jure zafi da ke aiki a ƙarƙashin yanayin zafi mai zafi, haka kuma don waldar ƙarfe na chrome mai tauri (kamar Cr5Mo, Cr9Mo, Cr13, Cr28 da sauransu).

HALAYE:

E310-16shine Cr26Ni21 bakin karfe na lantarki don kayan aikin matsa lamba na fata.Dukansu AC da DC za a iya amfani da su ga duk matsayi waldi.Wannan lantarki yana da kyau waldi tsari yi, da kuma ajiya karfe yana da kyau kwarai hadawan abu da iskar shaka juriya a karkashin 900-1100 ℃ high zazzabi yanayi.

HANKALI:

1. Kafin waldawa, da lantarki za a gasa a 300-350 ℃ for 1 hour da kuma amfani da yadda ake bukata.
2. Cire tsatsa, maiko, danshi da sauran datti kafin walda.
3. Ana ba da shawarar samar da wutar lantarki na DC, saboda zurfin walda a halin yanzu yana da ɗanɗano kaɗan, na yanzu bai kamata ya zama babba ba, don guje wa ja da fashe fata.
4. Rage shigarwar zafi gwargwadon yuwuwar, kuma girman girman wutar lantarki bai kamata ya zama babba ba.
5. Preheat kuma kiyaye zafin jiki tsakanin tashoshi ƙasa da 150 ℃.

MATSAYIN welding:

PA, PB, PC, PD, PE, PF

KASHIN KASHIN KARFE NA welding: (Wt. %)

KAYAN KIRKI NA DUKKAN KARFE WELD:

HANKALI NA AIKI: (AC ko DC+)

KISHI:

5kg/akwatin, 4akwatuna/kwali, 20kgs/kwali, 50kwali/kwali.21MT -26MT ta 1X20 ″ FCL.

Duban tsantsa na walda:

Ga welds waɗanda matsin aiki bai wuce 0.3MPa ba, ana iya amfani da kananzir don gwajin hatimi.Za a gudanar da gwajin bisa ga tanadi kamar haka: 5.1.1.1 Zazzabi yayin gwajin kada ya zama ƙasa da 5°C.

Rufe wajen gwajin da farin foda, sa'annan a sanya isasshen kananzir a ciki.Gabaɗaya, bayan mintuna 15 zuwa 30, idan babu tabo mai baƙar fata a saman farin foda, ana ɗaukar weld ɗin mara aibi.Akasin haka, wajibi ne a cire wurin da ba daidai ba kuma a sake siyar da shi, sannan a gudanar da gwajin.

Lokacin amfani da matsa lamba na hydraulic don gwada ƙarfin akwati, yakamata a aiwatar da shi daidai da ƙa'idodi masu zuwa:

Matsin gwajin ya kamata ya tashi a hankali zuwa ƙasa da sau 1.5 na matsi na aiki.

Lokacin da walƙiya ya isa matsa lamba na gwaji, dole ne a kiyaye matsa lamba na mintuna 5.Idan an sami yoyo ko damshi akan walda, dole ne a yiwa ɓangaren da ya lalace alama, cirewa, sake waldawa, sannan a gwada shi.

A lokacin gwajin matsa lamba na workpiece, ba a yarda a gyara weld;kuma a lokacin da workpiece ne a karkashin gwajin matsa lamba, shi ba a yarda ya bugi weld.

Gwajin aikin injiniya na walda:

Za a ɗauki samfurin gwaji daga samfurori tare da kayan aiki iri ɗaya da sigogin tsari na sassan welded.

Nau'in da girman gwajin aikin ya kamata ya bi ka'idodin GB/T 2649 ~ 2653 masu dacewa.
