SOLID WIRE FOR GAS SHIELD ARC WELD FOR THIN STEEL PLATE

摘要

PROBLEM TO BE SOLVED: To provide a solid wire for gas shield arc weld for thin steel plate which is used for CMT weld, in which arc is stabilized especially in weld of a thin steel plate to reduce spatter generation amount, and which can acquire good bead shape and a weld part without high temperature crack.;SOLUTION: Provided is the solid wire for gas shield arc weld for thin steel plate, which is used for weld in which wire feed and energization control are performed between a molten pool and a contact tip. The wire includes: 0.05-0.12% of C, 0.1-0.3% of Si, 1.9-3.0% of Mn, 0.1-0.4% of Cu, 0.030% or less of P, 0.020% or less of S, and balance of Fe and inevitable impurities, by mass% to total mass of the wire. A value of A represented in the following formula: A=(Mn+S×10²)/Si is 10-35.;COPYRIGHT: (C)2015,JPO&INPIT
