Title:
HIGH-SPEED HORIZONTAL FILLET GAS SHIELDED METAL ARC WELDING METHOD
Document Type and Number:
Japanese Patent JPH09314383
Kind Code:
A
Abstract:
To provide a high-speed horizontal fillet gas-shielded metal arc by which no welding defects are generated even when the leg length is reduced to reduce the distortion of a welded structure in performing the horizontal fillet welding of a steel plate coated with shop primer.
In a horizontal fillet gas-shielded metal arc welding method of twoelectrode one-pool system using a flux-cored wire, the flux-cored wire which contains, by weight % to the total weight of the wire, 0.2-3.0% CaO, 0.2-2.0% MgO, 0.5-5.5% TiO2, 0.2-2.0% SiO2. and 0.03-0.5% metal fluoride (in terms of F), and satisfies the formulae (CaO+MgO)/(TiO2+SiO2)=0.30-1.50, (CaO+MgO)+(TiO2+SiO2)=2.0-8.0% is used at least for a preceding electrode.
