1. Core Functions

1. Multi-material compatibility

   • Special welding rods for carbon steel/stainless steel/cast iron : suitable for different base materials (such as J422 for Q235 steel, A102 for 304 stainless steel)

   • Special welding rods : heat-resistant steel (R307), low-temperature steel (W707), surfacing (D667) and other special working conditions

2. Welding process optimization

   • High-efficiency iron powder welding rod : deposition efficiency ≥130% (compared to ordinary welding rod), reducing the number of welding layers

   • Low hydrogen welding rod (such as J507): diffusible hydrogen content ≤ 5ml/100g, to prevent cold cracks

3. Improved operating performance

   • Cellulose electrodes (such as E6010): suitable for vertical downward welding, strong arc blowing force and deep penetration

   • Titanium calcium type welding rod (such as J422): easy to strike arc, small spatter, suitable for novice operators

4. Special environmental adaptation

   • Underwater welding rod : waterproof coating can operate in water depth of 100m

   • Anti-moisture absorption welding rod : resistant to high temperature baking (350℃×1h), performance does not decay in humid environment

2. Core Advantages

Strength guarantee :

• Weld tensile strength ≥490MPa (J507), matching the parent material performance
  Defect Control :

• Low sulfur and phosphorus formula (S≤0.015%, P≤0.025%), reducing the risk of thermal cracking
  Energy-saving and efficient :

• Iron powder welding rods save 30% of electricity and have a deposition rate of 12kg/h
  Environmental protection and safety :

• ISO 14001 certified, welding fume toxicity index ≤ 3.0 (GB/T 25777)

3. Professional inspection methods

We can provide professional inspection services, factory inspection, testing and certification services, and can also help with product procurement.
