Application Technology of Welding 600 Alloy Steel covered electrode

Covered electrode of 1 and WEWELDING 600 alloy steel has very favorable thermal expansion and cold shrinkage, which can minimize cracks and deformation.

2. When welding surface hardened metal which is sensitive to cracks, low-level welding is an ideal choice.

3. Cut the heavier parts into 90-degree V-shaped grooves.

4. Preheat 200℃ before welding high carbon steel; When welding spring steel, control the welding temperature to prevent the spring from softening.

5. Keep the arc length short and use narrow weld bead to prevent overheating.

6, before removing slag, let the welding parts cool.
