  • I-AWS E9016-B3 I-Electrode ye-Welding yentsimbi enganyangekiyo bubushushu i-R406 I-Electrode ye-Welding enganyangekiyo bubushushu

I-AWS E9016-B3 I-Electrode ye-Welding yentsimbi enganyangekiyo bubushushu i-R406 I-Electrode ye-Welding enganyangekiyo bubushushu

Inkcazo emfutshane:

I-R406 (AWS E9016-B3) yi-electrode yentsimbi enganyangekiyo bubushushu ye-pearlitic ene-hydrogen potassium coating equlethe i-2.5% Cr – 1% Mo.

I-AWS A5.5 E9016-B3

Inkcazo: I-R406 yi-electrode yentsimbi enganyangekiyo kubushushu be-pearlitic ene-hydrogen potassium coating equlethe i-2.5% Cr – 1% Mo. Zombini i-AC kunye ne-DC zingasetyenziswa, kwaye zinokudityaniswa kuzo zonke iindawo. I-weldment kufuneka ifudunyezwe ukuya kwi-160 ~ 200°C ngaphambi kokuba idityaniswe.

Ukusetyenziswa: Isetyenziselwa ukuwelda izakhiwo zentsimbi ezimelana nobushushu ze-Cr2.5Mo, ezifana nemibhobho enobushushu obuphezulu kunye noxinzelelo oluphezulu enamaqondo obushushu angaphantsi kwama-550 ° C, oomatshini beekhemikhali zokwenziwa, kunye nezixhobo zokuqhekeka kwepetroliyam.

Isaziso:

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

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