JQ.MH00Cr24Ni13 stainless steel submerged-arc welding wire
Features
Compared with manual welding, the deposition speed can be increased by 2-4 times, and the deposition efficiency is as high as 90%.
The adaptability of current and voltage is large, the setting of welding conditions is easy, and it is easy to carry out semi-automatic and automatic welding.
Good slag removal and glossy weld bead surface. In addition, there is little splash, the arc stability is excellent, and the X-ray is qualified.

Precautions for product use
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.
The above suggestions are for reference only, and the actual situation shall prevail in the specific operation. If necessary, process qualification should be carried out before determining the welding plan.
