Baoji Taicheng Clad Metal Materials Co., Ltd, as a titanium-steel clad plates manufacturer, would like to introduce to you today, what are the common quality problems of titanium-steel clad plates? In the production and use of titanium steel clad plates, the most common quality problems are generally 2, clad plate defects, and welding defects. Among them, the defects of the composite plate are mainly due to insufficient separation rate, surface cracks in the titanium layer and steel layer, etc.; welding defects mainly include pores, cracks, incomplete penetration, and slag inclusion.
Prevention measures adhere to the incoming re-inspection system for composite board defects, and the separation of composite boards should be inspected one by one.
For transition joints, flanges, etc., for composite plates that do not consider the strength of titanium materials, flaw detection requires continuous 100% ultrasonic flaw detection within a 50mm wide range around, and 200mm spacing flaw detection for other areas. Others, 100% flaw detection. When the plasticity of the composite plate is poor, it should be re-annealed to relieve stress, improve its performance, and avoid subsequent manufacturing defects.
When the bending operation is required for the reel and the stamping head number pull plate, when the temperature is low, the bending part should be preheated by flame to avoid bubbling or cracking. When planning and drilling holes, the cutting and drilling operations should be processed from the titanium layer to the steel layer as much as possible to avoid tearing the composite board or forming cracks.
Welding defects Welding titanium layer should use argon gas with a purity of not less than 99.99% as maintenance gas. In addition, the welding wire is not allowed to have cracks and interlayers. Before welding, carefully clean and dispose of the workpiece welding area. If the ambient temperature is lower than 5℃, the base steel surface should be preheated by flame. Regarding the titanium-steel composite plate equipment, the titanium welding seam processing technology is strip processing. The titanium layer within 15mm of the edge of the composite plate will be removed. The steel seam will be welded first, and then the steel seam will be completely covered with a 50mm wide titanium strip. Stop Welding titanium layers with argon maintenance.
