How are steel lined planer knives welded? What kind of electrode is used for milling machine planer

Milling machine planer knife sitting should be cast iron with wewelding777 cast iron electrode welding, the cost of this electrode is relatively high, but the crack resistance will be excellent, welding cast iron, cast iron and carbon steel dissimilar welding strength to reach 480MPa tensile strength is better, generally suitable for welding quality special requirements or the importance of the product is more important to use, if considering the cost of welding rod can also use low-cost J506 or Z308 electrode, preheating 550 degrees after welding insulation and slow coolingHowever, there is a certain risk of cracks, and the cost of welding rods will be relatively low.

What kind of welding rod is wewelding777 cast iron electrode for maintenance?

1. AWS SFA standard.

2. It is suitable for all kinds of cast iron (including ductile iron, gray iron, high CR maintenance welding), as well as dissimilar welding of cast iron and steel.

3. It is used for low-pressure water welding of cast iron pipes.

4. Alloy metal welding core design, coated with unique flux, with anti-cracking function.

5. The weld deposition layer can be machined.

2. What is wewelding777 used for?

Welded cast iron and steel, welded with different cast irons Transmission gearbox.

Grey cast iron, malleable cast iron or ductile iron sewer pipes.

3. Wewelding777 technical parameters.

Tensile strength: 70,000 psi (482 Nv. mm²).

Yield strength: 62,000 (427 Newtons square mm²).

Hardness (HB): 185HB Color matching with base metal: similar.

Power selection: AC and DC dual-purpose, DC reverse connection when DC.

Fourth, process parameters.

Diameter (mm).

Current (amps) 60-100 85-110 90-140

5. Tips for the use of wewelding777.

1. It is necessary to do proper surface cleaning before welding, and it is recommended to cut the welded joint into a U-shaped groove.

2. Crack holes at both ends of the crack to prevent the expansion of the crack during the welding process.

3. When the repair angle is not good, you can choose the wewelding100 electrode cold slotting to form an effective U-shaped or V-shaped groove.

4. Weld with as little current as possible, medium arc length, and slightly inclined to the welding direction.

5. It is recommended that the weld bead should be short, thin and narrow transversely oscillating torch to fill the weld before stopping the arc welding, usually without heat treatment, allowing the parts to cool slowly.
