Disadvantages of composite board
1) Adhere to the incoming material re inspection system, and the bonding condition of composite plates shall be inspected one by one. Focus on transition joints, flanges, etc. For the composite plate of titanium material without considering the strength, the flaw detection requires 100% ultrasonic flaw detection within 50mm around, and the rest areas shall be subject to 200mm spacing flaw detection. 100% flaw detection for the rest.
2) When the plasticity of the composite plate is poor, it should be annealed from scratch to eliminate stress, improve its performance and avoid defects in subsequent manufacturing.
3) When winding operation is required for the pull plate such as drum and stamping head, when the temperature is low, the flame shall preheat the winding part to avoid bubbling or crack.
4) During the operations of gouging and drilling pipe holes, the blanking and drilling operations shall be processed from the titanium layer to the steel layer as far as possible to avoid tearing the composite plate or forming cracks.
2. Welding defects
1) Argon with purity no less than 99.99% shall be used as maintenance Gas for welding titanium layer. In addition, the welding wire is not allowed to have cracks and interlayer.
2) Carefully clean and treat the welding area of the workpiece before welding. When the ambient temperature is lower than 5 ℃, use flame to preheat the base steel surface.
3) As for the titanium steel clad plate equipment, the titanium weld processing process is strip bonding processing. The titanium layer within 15mm of the edge of the clad plate shall be removed. The steel weld shall be welded first, and then the steel weld shall be completely covered with 50mm wide titanium strip. The titanium layer shall be welded and maintained together with argon.
4) For the micro cracks on the surface of the composite plate, the defects must be removed and cleaned before repair welding. For small cracks, the direct repair welding method can be selected.
5) If the area is large, the material must be replaced. If the area is small, it can be made up. The unbound area shall be reinforced with titanium rivets, and the number of rivets shall be less.
Stainless steel composite plate has the characteristics of all kinds of carbon steel and stainless steel. It is welcomed by users with its excellent performance price ratio and has broad market prospects. But interestingly, since the 1950s, through the ups and downs of the development process for more than half a century, many people still don't know it. More people haven't used it. It should be said that the shopping mall of stainless steel clad plate is far from entering the mature stage and is still in the process of development. The exploration and efforts of scientific and technological workers to build a resource-saving society will never stop.
