I-AWS E7015-A1 I-Electrode yentsimbi enganyangekiyo bubushushu i-R107 Iintambo zokuWelda zeHydrogen eziphantsi ezinamathelayo Umfanekiso obonisiweyo
  • I-AWS E7015-A1 I-Electrode yentsimbi enganyangekiyo bubushushu i-R107 Iintambo zokuWelda zeHydrogen eziphantsi ezinamathelayo

I-AWS E7015-A1 I-Electrode yentsimbi enganyangekiyo bubushushu i-R107 Iintambo zokuWelda zeHydrogen eziphantsi ezinamathelayo

Inkcazo emfutshane:

I-R107 (AWS E7015-A1) yi-electrode yentsimbi enganyangekiyo bubushushu ye-pearlitic ene-hydrogen sodium coating ephantsi equlethe i-0.5% Mo.

I-GB/T E5015-A1

I-AWS A5.5 E7015-A1

Inkcazo: I-R107 yi-electrode yentsimbi enganyangekiyo bubushushu ene-hydrogen sodium coating ephantsi equlethe i-0.5% Mo. Sebenzisa i-DCEP (i-electrode yangoku ngqo) kwaye ingadityaniswa kuzo zonke iindawo. I-weldment kufuneka ifudunyezwe ukuya kuthi ga kwi-90 ~ 110 ℃ ngaphambi kokuba idityaniswe.

Ukusetyenziswa: Isetyenziselwa ukuwelda imibhobho yebhoyila enobushushu obuphantsi kwama-510°C (njenge-15Mo, njl.njl.), kwaye ingasetyenziselwa ukuwelda intsimbi enamandla aphantsi.

Isaziso:

1. I-electrode mayibhakwe iyure e-1 kwi-350℃ ngaphambi kokuba isebenze nge-welding;

2. Kubalulekile ukucoca umhlwa, isikali seoyile, amanzi, kunye nokungcola kwiindawo zokuwelda ngaphambi kokuba uwelda.
