JQ.MH00Cr21Ni10 stainless steel submerged-arc welding wire

1. The temperature between welds is recommended to be controlled at about 150°C. When multi-pass multi-layer welding of small and medium-sized specifications, pay attention to controlling the welding line energy. 2. The rust layer, moisture, oil, dust, etc. of the welding part must be cleaned up. 3. The flux must be baked at 300-350℃ for 2h before use.
