PT inspection for what ?

Tint inspection is a method of nondestructive testing. It is a surface inspection method, mainly used to detect surface damage such as cracks that cannot be recognized by the naked eye, such as the detection of stainless steel near surface defects (cracks), pores, porosity, stratification, penetration and fusion defects (also known as PT inspection). It IS SUITABLE FOR INSPECTING COMPACT METAL MATERIALS (WELDS), NON-METALLIC MATERIALS (glass, ceramics, fluorine plastics) and defects (cracks, pores, etc.) on the surface of products. The basic principle of color detection: the surface of the material is coated with colorant, and the colorant penetrates the damaged part. Rinse the colorant off the surface after a period of time. The surface that has been cleaned is coated with a developer, and the damaged area can be seen clearly because the colorant has penetrated into it. The capillary phenomenon is mainly used to make the permeate into the defect, and the surface permeate is removed by cleaning agent, and the permeate remains in the defect, and the capillary action of imaging agent is used to adsorb the residual permeate in the defect to achieve the purpose of testing the defect. Pre-clean the workpiece surface Before applying penetrant inspection surface, should use cleaner clean surface clean, makes checked surface without oil, rust, chip, and other dirt lacquer layer (such as inspection of weld, on the surface of weld and weld edge should not be oxided surface scale, welding slag, spatter, etc), and then, makes the surface of the workpiece t

Characteristics of Sand Casting

There are 7 distinctive characteristics of sand casting you have to know if you are working in machinery industry. The strength of chemically hardened sand mold is much higher than that of clay sand mold, and after being made into sand mold, it is hardened to a relatively high strength and then demolded, and no repairing is required. Therefore, the mold can more accurately reflect the size and contour shape of the pattern, and it is not easy to deform in the subsequent process. The obtained casting has high dimensional accuracy. Because the viscosity of the binder and hardener used is not high, it is easy to mix with the sand particles. The sand mixing equipment is light in structure, low in power and high in productivity, and the sand processing part can be simplified. The mixed molding sand has good fluidity before hardening, and the molding sand is easy to be pounded during molding, so a large and complicated molding machine is not required. When modeling with chemically hardened sand, pattern materials such as wood, plastic and metal can be selected according to production requirements. The content of binder in chemically hardened sand is much lower than that of clay sand, and there is no powdery auxiliary material in it. If the original sand with the same particle size is used, the gap between sand particles is much larger than that of clay sand. In order to avoid metal infiltration between the sand grains during
