Application of Microscope in Welding Penetration Testing Technology
Testing method:
1. Pre-welding inspection penetration depth and penetration width analyzer
Pre-welding inspection includes inspection of raw materials (such as base metal, welding rod, flux, etc.), penetration microscope, inspection of welded structure design, etc.
2. Inspection of penetration depth and width of molten pool during welding
Including inspection of welding procedure specification, inspection of weld size, inspection of fixtures and structural assembly quality, etc.
3. Inspection of finished products after welding Computerized Penetration Measuring Microscope-
There are many methods for post-welding finished product inspection, and the commonly used ones are as follows:
4. Appearance inspection welding penetration depth measurement
The appearance inspection of welded joints is a simple and widely used inspection method. The penetration depth of the weld is an important content of the inspection of the finished product. The weld width is mainly to find defects on the weld surface and dimensional deviations. Generally, the measurement of weld penetration is carried out through visual observation and with the help of standard templates, gauges and magnifying glasses. If there is a defect on the surface of the weld, there is a possibility of a defect inside the weld.
5. The effective penetration of the weld is tested for compactness
Welding vessels for storage of liquid or gas, the non-dense defects of the weld are measured by the measurement of penetration width and penetration depth, such as penetration depth of cracks, pores, slag inclusion, incomplete penetration and loose structure. Deep, can use the compactness test to find the welding depth test of the seat connector of the auto parts. The compactness test methods include hot plate welding test of auto parts: kerosene test, water-carrying test, water-washing test, etc.
