What is the welding quality testing standard of automatic hobbing welding machine for steel bar frame?

The welding quality testing standard of the automatic hob-welding machine mainly includes the following aspects: the quality requirements of the solder joints: reliable electrical connection: welding should ensure good electrical contact to ensure the stable transmission of current. Sufficient mechanical strength: The solder joint should have sufficient mechanical strength to prevent it from falling off or loosening when subjected to vibration or impact. Clean and neat appearance: the appearance of the solder joint should be good, the amount of solder should be just right, no pulling tip, bridge, crack, pinhole, slag inclusion and other phenomena, and does not damage the insulation layer of the wire and adjacent components. Weld quality standards: Guarantee items: welding materials should meet the design requirements and relevant standards, welders must pass the examination, I, II welds must pass the inspection, and should meet the design requirements and construction and acceptance specifications. Basic items: The shape of the weld should be uniform, the transition between the weld pass and the weld pass, the weld pass and the base metal should be smooth, and the welding slag and splash should be cleared. Allowable deviation items: the size of the weld should be consistent with the size specified in the design, or the weld molding should be good, and there should be no high or low, wide or narrow situations. In order to ensure the quality of welding, the welding process should be strictly in accordance with the operating procedures, and the welding quality should be regularly tested and evaluated. At the same time, when using the automatic hobbing welding machine for the steel pole skeleton, attention should also be paid to the maintenance and maintenance of the equipment to ensure its normal operation and the stability of the welding quality.
