Inkcazo: I-R407 yi-electrode yentsimbi enganyangekiyo kubushushu ye-pearlitic ene-hydrogen sodium coating ephantsi equlethe i-2.5% Cr – 1% Mo. Sebenzisa i-DCEP (i-electrode yangoku ngqo) kwaye i-can welded kuzo zonke iindawo. I-weldment kufuneka ifudunyezwe ukuya kuma-200 ~ 300°C ngaphambi kokuba i-weld.

Ukusetyenziswa: Isetyenziselwa ukuwelda imibhobho enobushushu obuphezulu kunye noxinzelelo oluphezulu enobushushu obuphantsi kwama-550°C, oomatshini beekhemikhali zokwenziwa, izixhobo zokuqhekeka kwepetroliyam, njl.njl.

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.
