ISICELO:
Ukuwelda kweentsimbi ze-9% Cr-1% Mo kunye neentsimbi ze-9% Cr – 2% Mo ezisetyenziselwa umbane kunye nesitya soxinzelelo oluphezulu.
IINKCAZELO:
I-PA-8016-B8 yi-electrode ye-hydrogen ephantsi enesinyithi se-weld esenziwe yi-9%Cr-1%Mo. Yenzelwe intsimbi eshushu kakhulu kunye neentsimbi ezisetyenziswa kwiinkonzo ze-hydrogen eshushu, ingakumbi kushishino lwe-petrochemical. I-electrode ingavunywa ngenxa yamandla ayo aphezulu okutsalwa, ukuqina okuhle kunye nokumelana nobushushu okukhulu.
AMANQAKU NGOKUSETYENZISWA:
1. Yomisa ii-electrode kwi-350-400°C malunga neyure enye ngaphambi kokuba uzisebenzise kwaye ugcine ii-electrode kwi-100-150°C emva kokuzomisa ngononophelo ukuze zingabi namanzi.
2. Sebenzisa indlela yokubuyela umva okanye ubethe i-arc kwipleyiti encinci yesinyithi elungiselelwe le njongo ukuthintela ukuvuthuza kwi-arc ukuqala.
3. Gcina i-arc imfutshane kangangoko.
4. Fudumeza kwi-100-150°C. Ubushushu obuza kusetyenziswa buyahluka ngokuhambelana nobukhulu bepleyiti kunye nohlobo lwentsimbi eza kudityaniswa.
5. Nika ingqalelo ukuba ungadluli kwi-heat-input efanelekileyo kuba i-heat-input egqithisileyo ibangela ukonakala kwexabiso lempembelelo kunye namandla emveliso yesinyithi esitshixiweyo.
IV. UKWAKHIWA KWEKHEMIKHALI OKUQHELEKILEYO KWESINYITHI ESIWELDWE (%):
| C | Si | Mn | Cr | Mo |
| 0.06 | 0.42 | 0.68 | 9.38 | 1.05 |
V. IIPROPATHI ZOKWENZA EZIQHELEKILEYO ZE-WELD STEAL:
| Amandla okuThamba N/mm2(Ksi) | Incopho yokuKhula N/mm2 (Ksi) | Ukwandiswa % | I-PWHT |
| 705 (102) | 560 (81) | 24 | 740°C x iyure e-1 |
VI. IINDLELA ZOKUWELDA: ZONKE IINDLELA
VII. UBUKHULU NOLUHLU LWANGOKU LUCETYISWAYO (AC/DC+):
| Ububanzi (mm) | 2.5 | 3.2 | 4.0 | 5.0 | |
| Ubude (mm) | 350 | 350 | 400 | 400 | |
| I-Ampere | Iflethi | 55 – 85 | 90 – 130 | 130 – 180 | 180 – 240 |
| V kunye ne-OH | 50 – 80 | 80 – 115 | 110 – 170 | 150 – 200 |
