The composite plate has excellent performance and low cost. The common quality problems of the composite plate are mainly non bonding after explosion, insufficient bonding rate and strength, and local surface defects of titanium layer and steel layer, such as pits and cracks. In view of these problems of composite boards, Xiaobian of Jinan composite board factory believes that the precautions to be taken during manufacturing are mainly as follows:
1. Adhere to the incoming material reinspection system, and conduct nondestructive testing on the bonding condition of composite plates one by one. Mainly in the plate edge, initiation point and other areas.
2. For the micro cracks on the surface of the composite plate, the defects must be cleaned before repair welding. Direct repair welding can be used for small cracks.
3. Recheck the mechanical properties of the composite plates one by one to verify the shear properties after annealing and prevent defects in subsequent fabrication. At the same time, the surface to back bending test was carried out to verify the bonding performance.
4. During beveling and pipe drilling, blanking and drilling shall be conducted from the titanium layer to the steel layer as far as possible to prevent the composite plate from tearing or forming cracks.
5. When bending is required for composite plates such as drums and stamping heads, the edge joint of titanium composite plates shall be peeled off. When the temperature is low, it shall be heated to a certain temperature before bending to prevent edge cracking.
6. For the unfitness found in the inspection, if the area is large, the material must be replaced. If the area is small, it can be remedied, and the unbound area can be reinforced with titanium screws. The subsequent operations are performed after the first processing.
The precautions to be taken during the manufacture of composite boards are answered from six aspects. If you have any doubts or needs, you can come to our website at any time Consult and understand!
