Title:
HIGH-SPEED HORIZONTAL FILLET GAS SHIELDED ARC WELDING METHOD
Document Type and Number:
Japanese Patent JPH07314175
Kind Code:
A
Abstract:
PURPOSE: To provide a high-speed horizontal fillet gas shielded arc welding method which prevents bit generation by a primer cracking gas at the time of welding primer coated steel sheets and makes it possible to stably obtain good bead shapes.
CONSTITUTION: A flux cared wire having a flat section of a minor axis/major axis 0.05 to 0.40 and contg. TiO2 at 2.0 to 6.0wt.% by the total weight of the wire is used at least for a preceding electrode and welding is executed by arranging the wire in such a manner that its major axis direction is a weld line direction in the two-electrode horizontal fillet gas shielded arc welding method to be executed by forming one pool.
