钛合金大型分段焊接制造质量控制分析

Quality Control Analysis on Large Section Welding of Titanium Alloy

为了提高钛合金焊接质量,为增材制造等先进制造技术的应用奠定良好基础,以大型分段焊接制造为例,开展质量控制分析。立足于产品制造过程,对原材料质量检验过程、切割下料过程、部件装焊过程,以及中、大组立装焊过程中的质量控制措施进行探讨。以人、机、料、法、环、测为闭环分析体系,对现场焊接管理工作进行要素分析,明确了车间质量员、专职检验员在全过程质量控制中的职能职责。最后,针对当前质量控制中普遍存在的问题,提出解决对策。建立了每一次焊接施工都做到准备充分、预检彻底、整改及时、一次交验的质量控制体系。

In order to improve the welding quality of titanium alloy,and further lay a good foundation for the application of advanced manufacturing technologies such as additive manufacturing,the quality control analysis is carried out by taking large scale welding manufacturing as an example.Based on the product manufacturing process,discussed are the quality control measures in the processes including raw material quality inspection,cutting and blanking,assembly and welding of components,and assembly and welding of medium-scale and large-scale.By taking personnel,machine,material,method,environment and test as the closed loop analysis system,analyzed are the key elements of field welding management,and clarified are the functions and responsibilities of workshop quality controller and full-time inspector in the whole process of quality control.Finally,in view of the common problems in the current quality control,established is a quality control system to ensure that every welding construction is fully prepared,thoroughly pre-inspected,timely rectified and once delivered.
