Welding System

FEATURES Used for the synchronous processing of the spigot at both ends of the steel pipe. The vertical and horizontal feeding of the tool is driven by hydraulic pressure, which produces smooth feeding with high precision. The workpiece’s clamping, positioning, tool feeding and withdrawing are automatically done in sequence with high productive efficiency.
