I weld on the API X65 with Nickel consumble(N06625) use auto-TIG(hot wire), the surface prepared clearly with machining and acetone. The parameter : 200A ,10.1V,travel speed100mm/min, feeding speed 2.0m/min,wave width 6mm,wave speed 1500mm/min,dwell time bothside0.5s, 99.99%Argen shielding flow 12L/min. During welding, I can see some flotage(colour is offwhite) on the melt metal. who know what it is? And how to eliminate it during welding? |
