Significant Process Advantages
High welding efficiency: Utilizes resistance heat generated by electric current passing through the pipe seam to melt the metal, which is then extruded to form a weld joint. This allows for fast welding speeds, making it suitable for large-scale industrial production.
Stable welding quality: The welding process is automatically controlled by equipment, with precisely adjustable parameters (e.g., current, pressure, welding speed), minimizing human error and ensuring consistent weld quality.
Narrow heat-affected zone (HAZ): Concentrated heat input limits the heating range of the base metal, reducing thermal damage such as grain coarsening or hardness changes, and maintaining the pipe’s mechanical properties.
Controllable Dimensions and Precision
Wide size range: Capable of producing pipes with diameters from a few millimeters to thousands of millimeters, and flexible wall thicknesses to meet various engineering needs (e.g., small-diameter fluid pipes or large-diameter structural pipes).
High precision: Pipe diameter, wall thickness, and straightness are accurately controlled via rolling mills and sizing equipment, with tight dimensional tolerances—ideal for applications requiring high installation precision (e.g., mechanical components, pipeline systems).
Smooth surface finish: The weld seam is flat both inside and outside after welding, requiring minimal additional processing and suitable for applications with aesthetic requirements.
