Welding penetration testing technology

Welding is widely used in industrial production as an important means of material processing. With the continuous development of welding technology and the improvement of welding technology, penetration depth analysis systems require higher and higher welding quality in various industries. Industrial upgrading is imminent. Welding penetration analyzer and welding quality detection are crucial to the industrial upgrading of the machinery manufacturing industry. In response to this situation, Shanghai Tiansheng Instrument Factory has developed a microscope that measures welding penetration according to industry standards (hb5282-1984 Structural steel and Stainless Steel resistance spot welding and seam welding quality inspection, hb5276-1984 penetration depth inspection microscope aluminum alloy resistance spot welding and seam welding quality inspection) Welding quality inspection system, welding penetration depth microscope This system is equipped with sample welding spot cutting, pre Grinding, polishing, chemical processing unit, penetration microscope system (ZOOM-700) and plane image measurement system (TX-3000c). The system can image, edit, measure, export data, and print reports on butt joints, handovers, overlaps, and penetration of t-welded parts. In particular: automotive tooling fixture molds, automotive inspection tools, fusion welding detector car seat parts, automotive seat belts, automotive parts welding penetration detection automotive filters, and other various welding devices, the following is Shanghai Tiansheng Instrument Factory The actual cutting of the product, the shooting and measurement results of the welding penetration measurement microscope. Compared with similar products, this system has the characteristics of clear imaging, computer-based weld penetration measurement microscope with high contrast and high precision. Can achieve the most perfect true color observation and photographic effect.

Welding inspection Weld penetration depth microscope includes materials, tools, equipment for measuring weld penetration depth microscope, process and finished product quality inspection from drawing design to product manufacturing. Weld penetration depth measurement microscope is divided into There are three stages: pre-weld inspection, inspection during welding, and inspection of finished products after welding. Welding penetration testing and inspection methods for pressure vessels can be divided into destructive testing and non-destructive testing for welding penetration of steel boiler pipes according to whether they cause damage to the product.

1) Pre-weld inspection penetration depth and width analyzer Pre-weld inspection includes inspection of raw materials (such as base metal, welding rod, flux, etc.), penetration depth microscope, inspection of welded structure design, etc.

2) Inspection of deep penetration and deep molten pool during the welding process, including inspection of welding process specifications, inspection of welding seam size, inspection of fixture conditions and inspection of structural assembly quality, etc.

3) Inspection of finished products after welding with computer-type solution depth measuring microscope-
There are many methods for the inspection of finished products after welding, and the following are commonly used:

4. Appearance inspection Welding penetration depth measurement The appearance inspection of the welded joint is a simple procedure and widely used inspection method. The penetration depth of the weld is an important content of the finished product inspection. Surface defects and dimensional deviations. Generally, through the naked eye observation, with the help of tools such as standard model, gauge and magnifying glass, the measurement of weld penetration depth is checked. If there is a defect on the surface of the weld, there may be a defect inside the weld.

5. Denseness inspection of the effective penetration of the weld seam. Welding containers storing liquid or gas. The non-density defects of the weld seam are measured by the melting width and penetration depth, such as the penetration depth of penetration cracks, pores, slag inclusions, Welding depth and loose tissue are measured by optical methods, and the penetration test can be used to detect the penetration depth of the seat connector of the auto parts. Denseness inspection methods include hot plate welding inspection of auto parts: kerosene test, water load test, water flush test, etc.
