Disadvantages of composite board

1）堅持來料復驗制度，復合板的結合狀況應逐張檢驗。是過渡接頭、法蘭等。對鈦材不考慮強度的復合板，探傷要求周邊50mm寬的范圍內接連100%超聲波探傷，其余區域做200mm間距探傷。其余，100%探傷。

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)復合板塑性差時，要從頭退火，消除應力，進步其性能，避免后續制造發生缺點。

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)對卷筒、沖壓封頭等牽扯板需要曲折操作時，當溫度低時，要火焰預熱曲折部位，避免發生鼓泡或裂紋。

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、鉆管孔操作時，下料和鉆孔操作要盡量從鈦層向鋼層方向加工，避免將復合板扯開或形成裂紋。

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、焊接缺點

2. Welding defects

1)焊接鈦層要用純度不低于99.99%的氬氣做維護氣體。此外焊絲不允許有裂紋、夾層。

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)焊接前認真清理、處理工件焊接區。環境溫度低于5℃，使用火焰預熱基層鋼面。

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)關于鈦鋼復合板設備，鈦焊縫加工工藝為貼條加工，行將復合板邊部15mm范圍內鈦層去除，先焊接鋼材焊縫，再用50mm寬鈦板條將鋼焊縫完全覆蓋，進行鈦層的焊接，一起氬氣維護。

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)對復合板外表微裂紋必須將缺點清除潔凈后再進行補焊。關于小裂紋可選用直接補焊法。

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)關于制造以及成檢過程中發現的不貼合，若面積大必須替換材料，若面積小，可以選用彌補，用不結合區用鈦鉚釘進行加固，鉚釘以少為宜。

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.

不銹鋼復合板兼具各種碳素鋼和不銹鋼的特色，以其優異的性能價格比為用戶歡迎，有廣闊的商場前景。但有趣的是，從五十年代開始，通過半個多世紀風風雨雨的開發過程，仍然有很多人不知道它。更多的人未運用過它。應該說不銹鋼復合板的商場遠未進入成熟期，仍在開發過程中。 科技工作者為建造資源節約型社會的探索和努力不會停止。

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.
