Quality Control
HAIFEI follows a structured quality control process for welding equipment manufacturing, covering material inspection, component checking, machine assembly, welding performance testing, and final inspection before shipment. For customized projects, we review the customer’s workpiece, welding process, fixture requirements, and production needs to ensure the machine is suitable for actual production.
Our QC process includes incoming material inspection, electrical system checking, welding trial testing, fixture accuracy inspection, final machine testing, and packing confirmation. Customer inspection, sample testing, and technical support are also available before delivery.
