HJ431A
HJ431(Type A) is a special flux for smelting electroslag pressure welding, which has three glassy particles of light green, dark green and reddish-brown in color, and the particle size is 6-30 mesh, 8-14 mesh and 8-20 mesh. The reddish-brown flux is a new variety specially designed for the welding of various grades of steel bars in building construction.
This product has the following features:
1. the arc is easy to weld, can use the steel bar itself to arc, no need to lead the arc ball.
2. arc welding process is stable, the voltage adjustment range is wide, the adjustment range is 35-45V.
3. In the welding process, the welding bag is moderate in size, good in shape, the bag is smooth and bright, without adhesion, edge biting, porosity and other defects.
4. easy to construct, can use a small power welding machine, welding larger diameter steel bar.
Note:
1.Before construction, the steel bars used should be tested, and the performance indexes between the diameter of the steel bars and the pressure flux for the current and voltage of the welding power supply and the duration of the arc process and the current process should be mastered to determine the parameters.
2.The butt surface of the steel bar should be smooth, the steel bar is vertical and the axis is concentric, effectively preventing the uneven welding bag and partial bag phenomenon caused by this.
3.Before welding, it is necessary to weld the surface of oil, water and excessive rust and other impurities, while extending the welding time or current, master the extrusion time. Can prevent poor welding and porosity phenomenon.
4.The flux should be kept waterproof. The flux should be baked at 200-300ºC for 2 hours before welding. When welding, the filling flux should be uniform to prevent bias and uneven welding package.
5.Pay attention to adjust the welding specifications when the power supply voltage changes and welding grade III and other external steel bars.
