Surface defect detection of seamless pipe production accessories
Through effective surface defect detection, non-conforming products in seamless pipe production accessories can be detected and removed in a timely manner, preventing them from entering the market and protecting the brand image and consumer interests of the enterprise. Meanwhile, surface defect detection can also provide a basis for improving product quality for enterprises, guiding the optimization and adjustment of production processes.
Methods for surface defect detection
Manual inspection: Although manual inspection can achieve precise surface inspection in some cases, its efficiency is low and the inspection results are easily influenced by subjective factors. Therefore, in the large-scale production of seamless pipe production accessories, manual inspection has gradually been replaced by automated inspection.
Machine vision inspection: Machine vision inspection uses optical imaging and image processing technology to perform non-contact inspection on the surface of seamless pipe production accessories. Through preset algorithms and models, machine vision systems can automatically identify and classify various surface defects. This method has the advantages of fast detection speed, high accuracy, and good stability, and has been widely used in surface defect detection of seamless pipe production accessories.
Laser detection technology: Laser detection technology uses a laser beam to scan the surface of seamless pipe production accessories, and detects surface defects by measuring the reflection or scattering characteristics of the laser beam. This technology has unique advantages in detecting small cracks, scratches, and other defects, and is not affected by environmental lighting conditions.
Eddy current testing technology: Eddy current testing technology infers the existence of surface defects by generating eddy currents on the surface of the object being tested and detecting changes in the eddy currents. This technology is very effective for detecting defects such as cracks and pits on metal surfaces, and does not require direct contact with the object being tested.
