Title:
被覆アーク溶接棒用Mg合金粉および低水素系被覆アーク溶接棒
Document Type and Number:
Japanese Patent JP5133089
Kind Code:
B2
Abstract:
To provide a Mg alloy powder for a coated electrode for arc welding which has the good low-temperature toughness of a weld metal, and is excellent in the anti-dropout property of a coating agent while satisfying welding operatability, and a low-hydrogen type coated electrode for arc welding using the same.
The Mg alloy powder is added to the coating agent when manufacturing the coated electrode for arc welding and includes 13-36 mass% Mg, 33-56 mass% Si and 15-45 mass% Fe, and has an average particle diameter of 50-200 μm. The low-hydrogen type coated electrode for arc welding includes 3-17 mass% of Mg alloy powder based on the whole mass of the coating agent.
