Piling steel surface treatment process

Piling pipe uses a dual wire, double submerged arc welding under the flux layer of the method using the wire and solder layer between the flux produced by the combustion heat of the arc, the molten solder and base metal wire is formed. The main features of the product one-sided submerged arc welding, not only the deposition rate, but also has deep penetration capability; Second, the arc and the weld zone is well protected, weld quality, compact, good weld appearance and smooth, able to meet various performance requirements of the weld.

Piling steel surface treatment process:
1 steel surface treatment, piling steel pipe manufacturer in order to avoid formation of oxide scale unwinding and formation process, shall establish a board cleaning device.
2 steel edge processing, steel side piling up rust and deburring devices to reduce the porosity may occur. The location of the best cleaning device installed in edge milling machine, cutting disc, the device structure is a plane wave can adjust the position of the gap capstan, fluctuating pressure plate edges.
3 weld profile, weld factor is too small, narrow and deep weld, gas and inclusion is not easy come, easy formation porosity and slag. General weld coefficient control at 1.3 - 1.5, thick-walled pipe welding maximum, minimum, thin walls.
4. Reduce secondary magnetic field in order to reduce the impact of magnetic blow, to make the position of the workpiece welding cable connections only from the solder terminals, avoiding some welding cable to the workpiece to produce secondary magnetic fields.
