Tshuaj Tshuaj Muaj Zog Cov Lus
| Lub ntsiab | Aws A5.18 (E70S-6) | Tuam Tshoj GB / T 8110 (ER50-6) | Muaj nuj nqi & Cov yam ntxwv |
|---|---|---|---|
| C (carbon) | Tsawg dua los yog sib npaug rau 0.15% | 0.06-0.15% | Kev tswj hwm Weld lub zog thiab kev nruj; Cov ntsiab lus ntau dhau yuav ua rau tawg. |
| Mn (manganese) | 1.40-1.85% | 1.40-1.85% | Deagidizer thawj; Txhim kho Weld lub zog thiab tawg tawm. |
| Si (silicon) | 0.80-1.15% | 0.80-1.15% | AUXILIANIA DAGE; Txhim kho weld fluidity thiab kev tawm tsam rau porosity. |
| S (Sulphur) | Tsawg dua los yog sib npaug rau 0.035% | Tsawg dua los yog sib npaug rau 0.035% | Impurity lub caij; Cov txiaj ntsig dhau los txo qis zuj zus thiab tawg. |
| P (phosphorus) | Tsawg dua los yog sib npaug rau 0.025% | Tsawg dua los yog sib npaug rau 0.025% | Impurity lub caij; Ntau cov ntsiab lus ua rau txias brittleness. |
| CU (Tooj) | Tsawg dua los yog sib npaug rau 0.50% | Tsawg dua los yog sib npaug rau 0.50% | Qeb ntxiv txoj kev xaiv; Txhim kho corrosion tsis kam (tsis - yuav tsum tau ua qhov xav tau). |

|---|---|---|---|---|
| Lub zog tensile | Ntau dua los yog sib npaug rau 483 MPa (70 ksi) | 580 MPa (84 ksi) | Ntau dua los yog sib npaug rau 500 MPa | Chav Sov, 100% CO₂ Shielding Roj |
| Paib lub zog | Ntau dua los yog sib npaug rau 400 MPa (58 ksi) | 470 MPA (68 KSI) | Ntau dua los yog sib npaug rau 420 mpa | Chav Sov, 100% CO₂ Shielding Roj |
| Elongation | Ntau dua los yog sib npaug rau 22% | 28% | Ntau dua los yog sib npaug rau 22% | Chav sov, ntsuas ntsuas ntev 50 hli |
| Kev Cuam Tshuam Tais (Kv₂) | Ntau dua los yog sib luag rau 27 j (30 degree, 20 lab) | 81-95 J (-30 DEGREE, 60-70 LTP) | Ntau dua los yog sib npaug rau 27 j (-29 degree) | - 30℃(AWS) / -29℃(Suav teb), v-motch |
Daim Ntawv Thov Kev Pom Zoo
| Xwm txheej | Hlau Hlau | Raug tam sim no | Tiv Thaiv Roj | Weld Kev Ua Yeeb Yam |
|---|---|---|---|---|
| Nyias - phaj phaj vuam (tsawg dua los yog sib npaug rau 3 hli) | 0.8-1.0mm | 50-150A | Cov pa dawb lossis roj sib xyaw | Kev zoo nkauj zoo nkauj, tsis muaj zog |
| Tuab - phaj vuam (loj dua los yog sib npaug rau 6 hli) | 1.2-1.6mm | 200-350A | Cov roj sib xyaw (piv txwv li, 80% ar +20% con₂) | Siab nkag, tsawg - kub nruj |
| Tsawg - qhov chaw ib puag ncig (-30 degree) | 1.0-1.2mm | 120-250A | Cov Roj Sib xyaw | Qhov tseem ceeb ntawm kev cuam tshuam cov tawv |
