Carbon Steel Welding Electrode J425G GB/T E4310 AWS A5.1 E6010
Description: J425G is a high cellulose sodium-coated vertical downward electrode. Use DCEP (direct current electrode positive), which is suitable for all-position vertical downward welding of the circular seam on the pipeline site. When welding the bottom layer, it can be welded on one side and formed on both sides, and the welding speed is fast. Application: Used for circumferential seam welding of various carbon steel pipes. Chemical composition of weld metal(%): | C | Mn | Si | S | P |
| ≤0.20 | 0.30~0.60 | ≤0.20 | ≤0.035 | ≤0.040 |
Mechanical properties of weld metal: | Test item | Tensile strength Mpa | Yield strength Mpa | Elongation % | Impact value (J) （-30℃） |
| Guaranteed | ≥420 | ≥330 | 22 | ≥27 |
X-ray inspection: II grade Recommended current: | Rod diameter （mm） | 2.5 | 3.2 | 4.0 | 5.0 |
| Welding current （A） | 40 ~ 70 | 70 ~ 110 | 110 ~ 160 | 160 ~ 190 |
Notice: 1. Unpack the welding rod before use, and use it up as much as possible after unpacking; 2. Generally, there is no need to dry it again before welding, and it can be dried at 70~90°C for 1 hour when it is damp. Wenzhou Tianyu Electronic Co., Ltd. was established in 2000.
