Title:
TIG WELDING METHOD AND TIG WELDING CONSUMABLES
Document Type and Number:
Japanese Patent JPH11138262
Kind Code:
A
Abstract:
To provide a TIG welding method and welding consumables with which weld metal not requiring any heat treatment to raise strength and having a high strength and a high toughness as welded is obtained and at the same time weldability is improved.
TIG welding consumables contain 0.08-0.14 wt.% C, 0.01-0.15 wt.% Si, 0.01-0.4 wt.% Mn, 8-10 wt.% Ni, 0.7-1.5 wt.% Cr, 0.7-1.5 wt.% Mo, 0.05-0.4 wt.% Nb or V or Nb+V, 0.002-0.02 wt.% Al, 0.07-0.4 wt.% Cu, 150 wt.ppm≤N, and the balance Fe with inevitable impurities. In the inevitable impurities, the contents are regulated to be ≤0.008 wt.% P, ≤0.008 wt.% S, ≤0.01 wt.% Ti, ≤5 wt.ppm B, ≤50 wt.ppm Ca, ≤50 wt.ppm Mg, ≤40 wt.ppm O and ≤2 wt.ppm H.
