Disadvantages of composite board

1）坚持来料复验制度，复合板的结合状况应逐张检验。是过渡接头、法兰等。对钛材不考虑强度的复合板，探伤要求周边50mm宽的范围内接连100%超声波探伤，其余区域做200mm间距探伤。其余，100%探伤。

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)复合板塑性差时，要从头退火，应力，进步其性能，避免后续制造发生缺点。

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)对卷筒、冲压封头等牵扯板需要曲折操作时，当温度低时，要火焰预热曲折部位，避免发生鼓泡或裂纹。

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)在刨破口、钻管孔操作时，下料和钻孔操作要尽量从钛层向钢层方向加工，避免将复合板扯开或形成裂纹。

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、焊接缺点

2. Welding defects

1)焊接钛层要用纯度不低于99.99%的氩气做维护气体。此外焊丝不允许有裂纹、夹层。

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)焊接前认真清理、处理工件焊接区。环境温度低于5℃，使用火焰预热基层钢面。

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)关于钛钢复合板设备，钛焊缝加工工艺为贴条加工，行将复合板边部15mm范围内钛层去除，先焊接钢材焊缝，再用50mm宽钛板条将钢焊缝完全覆盖，进行钛层的焊接，一起氩气维护。

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)对复合板外表微裂纹必须将缺点洁净后再进行补焊。关于小裂纹可选用直接补焊法。

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)关于制造以及成检过程中发现的不贴合，若面积大必须替换材料，若面积小，可以选用弥补，用不结合区用钛铆钉进行加固，铆钉以少为宜。

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.

不锈钢复合板兼具各种碳素钢和不锈钢的特色，以其优异的性能比为用户欢迎，有广阔的前景。但有趣的是，从五十年代开始，通过半个多世纪风风雨雨的开发过程，仍然有很多人不知道它。更多的人未运用过它。应该说不锈钢复合板的远未进入成熟期，仍在开发过程中。 科技工作者为建造资源节约型社会的探索和努力不会停止。

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.
