Abin da ya kamata a biya hankali a lokacin da argon baka waldi bakin karfe?

Dole ne a kula da abubuwan da ke gaba yayin amfani da waldawar argon:

1. Ana amfani da wutar lantarki tare da halaye na waje na tsaye, kuma ana amfani da polarity mai kyau a cikin DC (an haɗa waya mai walda zuwa madaidaicin iyaka).

2. Gabaɗaya ya dace da walƙiya na faranti na bakin ciki da ke ƙasa da 6mm, tare da halayen kyawawan ƙirar weld da ƙananan nakasar walda.

3. Gas mai kariya shine argon tare da tsabta ≥ 99.95%.Lokacin waldi na yanzu shine 50 ~ 150A, kwararar argon shine 6 ~ 10L / min, kuma lokacin da na yanzu shine 150 ~ 250A, kwararar argon shine 12 ~ 15L / min.Jimlar matsa lamba a cikin kwalbar kada ta kasance ƙasa da 0.5MPa don tabbatar da tsabtar cikawar argon.

4. Tsawon tungsten electrode protruding daga gas bututun ƙarfe ne zai fi dacewa 4 ~ 5mm, 2 ~ 3mm a wuraren da matalauta garkuwa kamar fillet waldi, 5 ~ 6mm a wuraren da zurfin tsagi, da kuma nisa daga bututun ƙarfe zuwa aiki ne. kullum ba fiye da 15mm.

5. Don hana faruwar ramukan walda, dole ne a tsaftace tabon mai, sikelin da tsatsa a bangon ciki da waje na sassan walda.

6. Tsawon baka na bakin karfe na waldawa shine 1 ~ 3mm, kuma tasirin kariya ba shi da kyau idan yana da tsayi sosai.

7. A yayin da ake goyan bayan gindi, domin a hana bayan ƙwanƙarar walda ɗin da ke ƙasa yin iskar oxygen, bayan kuma yana buƙatar kariya da iskar gas.

8. Domin kare waldi pool da kyau tare da argon da sauƙaƙe aikin walda, kusurwa tsakanin tsakiyar layin tungsten lantarki da workpiece a matsayin waldi za a kiyaye gaba ɗaya a 75 ~ 85 °, da kusurwar da aka haɗa tsakanin filler. waya da workpiece surface ya zama ƙanƙanta kamar yadda zai yiwu, gaba ɗaya kasa da 10 ° na bango kauri kuma ba fiye da 1mm.Domin tabbatar da matsi na walda, kula da kyakkyawar haɗin haɗin gwiwa, da kuma cika tafki narkakkar a lokacin tsayawar baka.
