Why Choose KOBELCO LB-52-18?

The LB-52-18 stands out from ordinary E7018 electrodes by offering enhanced workability and mechanical integrity

• 20% Higher Deposition Rate: Containing high iron powder content in the coating, the LB-52-18 delivers approximately 20% higher deposition rates than standard E7016 electrodes, significantly reducing labor costs and welding time. 
   
• Superior Mechanical Properties: Specifically formulated for 490MPa class high tensile steel, it provides excellent toughness and crack resistibility.
• Unsurpassed Arc Stability: Highly reputed for over 35 years, it offers unsurpassed arc stability and a superior weld bead profile, especially in DC all-position pipe welding.
• Low-Temperature Reliability: With high Charpy impact values, it is suitable for low-temperature applications down to -20°C.

Essential Usage Tips for Professionals

To achieve the best weld quality and prevent defects like porosity or cold cracking, follow these manufacturer guidelines:

• Redrying: Always re-dry electrodes at 300–350°C for 30–60 minutes before use to maintain a moisture content of 0.5% maximum.

• Backstep Technique: Use the backstep method at the arc start to prevent blowholes and porosity.
• Arc Length: Keep the arc length as short as possible during operation
