AWS A5.4 E317-16
Nqe lus piav qhia: A242 yog cov pa roj carbon tsawg Cr19Ni13Mo3 stainless hlau electrode nrog titanium-calcium txheej.Nws tuaj yeem siv rau AC thiab DC nrog kev ua haujlwm zoo heev.Cov hlau tso tawm muaj cov ntsiab lus molybdenum ntau dua li A202, thiab nws muaj kev tiv thaiv zoo dua rau cov tsis-oxidizing acids, xws li sulfuric acid, sulfurous acid, phosphoric acid thiab organic acids.Nws kuj muaj qhov zoo tiv thaiv pitting corrosion.
Daim ntawv thov: Siv rau kev sib txuas ntawm tib hom stainless hlau cov ntaub ntawv nrog rau cov hlau sib xyaw thiab cov hlau tsis sib xws.
Tshuaj muaj pes tsawg leeg ntawm weld hlau (%):
| C | Mn | Si | Cr | Ni | Mo | Cu | S | P |
| ≤ 0.08 | 0.5 ~ 2.5 hli | ≤0.90 | 18.0-21.0 Nws | 12.0 ~ 14.0 Nws | 2.0 ~ 4.0 | ≤ 0.75 | ≤ 0.030 | ≤ 0.040 |
Mechanical zog ntawm weld hlau:
| Cov khoom kuaj | Tensile zog Mpa | Elongation % |
| lav | ≥550 | ≥ 25 |
Pom zoo tam sim no:
| Qws txoj kab uas hla (mm) | 2.5 | 3.2 | 4.0 | 5.0 |
| Vuam tam sim no (A) | 50 ~ 80 | 80 ~ 110 ib | 110 ~ 160 ib | 160-200 Nws |
Daim ntawv ceeb toom:
1. Cov electrode yuav tsum tau ci rau 1 teev ntawm 150 ℃ ua ntej vuam ua haujlwm;
2. Vim tias qhov nkag mus tob tob yog ntiav thaum lub sij hawm AC vuam, DC fais fab mov yuav tsum tau siv ntau npaum li qhov ua tau kom nkag mus tob dua.thiab tam sim no yuav tsum tsis txhob loj dhau kom tsis txhob muaj qhov liab ntawm lub vuam pas nrig.
