1. Z308
Z308 is an alkaline welding rod suitable for welding ordinary medium carbon steel. This electrode has the characteristics of high strength, high hardness and good toughness after welding, so it is also suitable for welding spring steel plates. However, attention should be paid to controlling the current and electrode baking temperature during welding.
2.Z508
Z508 is a strong alkaline welding rod suitable for welding medium carbon steel and low alloy steel. The strength and toughness of this electrode after welding are better than Z308, so it can also be used to weld spring steel plates. However, attention should be paid to controlling the current and welding speed during welding.
3.Z408
Z408 is a perovskite composite electrode, suitable for welding cold work die steel, spring steel, etc. This electrode has the characteristics of high strength and good toughness after welding, which can ensure the quality of the weld. However, attention should be paid to the appropriate baking temperature when using it, and multiple heat treatments should be performed before welding.

Spring steel is best welded with WEWELDING600 electrodes with high crack resistance and tensile strength of 860MPA. Genuine WEWELDING600 electrodes are used for welding by cold welding process. WEWELDING 600 alloy steel welding rod is a special nickel-chromium alloy steel welding rod with low heat output and suitable for all-around welding. It has extremely wide versatility and is designed for high-strength general base metal strength, it has excellent welding process performance, stable arc, and uniform and beautiful welds, it has an excellent welding effect even in the presence of oil, water, and rust, and can weld different steels.
