AWS A5.5 E9015-B9

Tsananguro: R717 ielectrode yesimbi inodzivirira kupisa ine hydrogen sodium coating shoma ine 9% Cr - 1% Mo-V-Nb. Shandisa DCEP (direct current electrode positive) uye inogona kusungirirwa munzvimbo dzese. Nekuda kwekuwedzera kweNb neV shoma, simbi yakachengetwa ine resistance yakanaka kwazvo yekukwira tembiricha.

 

Mashandisirwo: Inoshandiswa pakunamira machubhu anopisa zvakanyanya uye misoro yemaboiler anodziya zvakanyanya uye ane simba guru, akadai seA213-T91/A335-P1 (T/P91), A387Cr, 91 nedzimwe simbi dzisingapisi.

Cherechedza:

1. Electrode inofanira kubikwa kweawa imwe pa350℃ isati yashandiswa pakunamira;

2. Zvakakosha kuchenesa ngura, mafuta, mvura, uye tsvina pazvikamu zvekunamira usati wanamira.

3. Pisa chikamu che weld pa 200 ~ 260°C usati wa welding, uye chengetedza tembiricha inoenderana ne interpass;

4. Tonhodza zvishoma nezvishoma kusvika pa80 ~ 100°C kwemaawa maviri mushure mekunamira; kana kurapwa kwekupisa kusingaitwe nekukurumidza sezvinobvira, kurapwa kwekubvisa hydrogenation kunogona kuitwa pa350°CX kwemaawa maviri.
