When the plasticity of the composite plate is poor, it needs to be re annealed to eliminate stress, improve its performance, and avoid defects in subsequent production.

坚持来料复验准则,复合板的结合情况应逐张查验。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宽的范围内连续100%超声波探伤，其他区域做200mm距离探伤。其他,100%探伤。3在创破口钻管孔操作时，下料和钻孔操作要尽量从钛层向钢层方向加工,防止将钛钢复合板撕开或形成裂纹。

Adhere to the principle of re inspection of incoming materials, and the bonding condition of composite boards should be checked one by one. The focus is on transition joint flanges, etc. For composite plates made of titanium material without considering strength, continuous 100% ultrasonic testing is required within a range of 50mm around the perimeter, and other areas are subjected to 200mm distance testing. Other, 100% inspection. When drilling pipe holes at the break point, the cutting and drilling operations should be carried out from the titanium layer to the steel layer as much as possible to prevent tearing or forming cracks on the titanium steel composite plate.

对卷筒冲压封头等牵扯板需要弯曲操作时,当温度低时,要火焰预热弯曲部位,防止产生鼓泡或裂纹。

When bending operations are required for pulling plates such as drum stamping heads, when the temperature is low, flame preheating should be carried out on the bent parts to prevent bubbles or cracks from occurring.

接着我们来看下后者钛钢复合板的焊接缺陷防治办法

Next, let's take a look at the prevention and control methods for welding defects in the titanium steel composite plate of the latter

焊接前认真清理处理工件焊接区。环境温度低于5°C ,应用火焰预热基层钢面。

Carefully clean and handle the welding area of the workpiece before welding. If the ambient temperature is lower than 5 ° C, the base steel surface should be preheated with flame.

焊接钛层要用纯度不低于99.99%的氩气做保护气体。此外焊丝不允许有裂纹层。

Welding the titanium layer requires argon gas with a purity of not less than 99.99% as the protective gas. In addition, the welding wire is not allowed to have a crack layer.

对复合板表面微裂纹必须将缺陷干净后再进行补焊。对于小裂纹可采用直接补焊法。

For micro cracks on the surface of the composite plate, the defects must be cleaned before repair welding. For small cracks, direct repair welding can be used.

对于制作以及成检过程中发现的不贴合,若面积大必须更换材料,若面积小,可以采用补救,胚结合区用钛铆钉进行加固,铆钉以少为宜。

For non adhesion found during the production and inspection process, if the area is large, the material must be replaced. If the area is small, remedial measures can be taken. The embryo bonding area should be reinforced with titanium rivets, and the number of rivets should be minimized.

对于钛钢复合板设备,钛焊缝加工工艺为贴条加工,即将复合板边部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,同时氩气保护。

For titanium steel clad plate equipment, the titanium weld processing process is stick processing, that is, remove the titanium layer within 15mm of the edge of the clad plate. First weld the steel weld, and then use 50mm wide titanium Flat noodles to completely cover the steel weld. At the same time, weld the titanium layer and protect it with argon.
