Application of Microscopes in Weld Penetration Analysis of Automotive Components
Welding, as a core material processing technology, is widely applied in industrial production. With the continuous advancement of welding processes and technologies, industries across all sectors have imposed increasingly stringent requirements on welding quality, driving the growing adoption of weld penetration analysis systems and dedicated microscopes.
Industrial upgrading has become an urgent priority, and weld penetration inspection plays a vital role in the industrial upgrading of the machinery manufacturing sector. To address this demand, Shanghai Yihong Optical Laboratory Equipment Factory has developed a welding quality inspection system built on industry-standard weld penetration measuring microscopes, compliant with the following specifications:
HB 5282-1984: Quality Inspection for Resistance Spot Welding and Seam Welding of Structural Steel and Stainless Steel
HB 5276-1984: Quality Inspection for Resistance Spot Welding and Seam Welding of Aluminum Alloys by Penetration Testing Microscopes
The system is equipped with sample preparation units for weld cutting, pre-grinding, polishing and chemical treatment, as well as the ZOOM-660E weld penetration microscope system and the CF-2000C planar image measurement system. It supports imaging, editing, dimensional measurement, data export and report printing for penetration analysis of butt, corner, lap and T-joint welds.
It is particularly suitable for weld penetration testing of a wide range of automotive welded components, including tooling fixtures and dies, automotive checking gauges, seat parts, safety belts, filters and other auto parts.
The following presents actual cut specimens and measurement results captured by the weld penetration measuring microscope from Shanghai Optical Instrument Factory. Compared with similar products, this computerized weld seam penetration measuring microscope features clear imaging, high contrast and high measurement accuracy, enabling intuitive true-color observation and photographic documentation.
