High-speed horizontal fillet gas shield arc welding process

摘要

PURPOSE: To provide a high-speed horizontal fillet gas shielded arc welding method which intensifies bead formability and primer resistance in high-speed horizontal fillet welding of shop primer coated steel sheets. ;CONSTITUTION: Welding is executed by using a flux cored wire contg., by total weight of the wire, 2.0 to 3.5% TiO₂, 3.0 to 6.5% slag forming agent (including TiO₂), 1.5 to 5.0% deoxidizing agent (including a sheath component), 0.3 to 1.0% iron oxide, 0.10 to 0.50% F and 0.10 to 0.40% Ni at least for a succeeding electrode in the 2-electrode horizontal fillet gas shielded arc welding method for the primer coated steel sheets to be executed by forming one pool. By this, high efficiency of the welding and lowering the cost are obtd.;COPYRIGHT: (C)1995,JPO
