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.

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.
