ERW pipe welding technology adopts skin effect principle produced by high frequency current to heat hot rolled coil to molten state, then through the mechanical extrusion method to weld. Adopting this welding technology, ERW pipe welding seam center will have a white fusion line, and the heat affected zone on both sides of the fusion line will produce metal flow from the central to the extension direction to the surface.
During the welding process, tube metal will round the heat cycle process cold, hot and cold again. So, parent metal physic-chemical properties, grain size and non-metallic inclusion as well as forming and welding conditions and heat treatment process will have an impact on the performance of the welded seam especially impact toughness.
In the process of ERW pipe, choosing the impact toughness of the plates ensure the performance of welded steel pipes, combination of control and adjustment of the welding process ensure to reduce defects as far as possible and improve the weld seam performance.
