process qualification
1.At first, regarding the product quality, we have completed adequate process/product qualification for both "with this yellow wire" and "w/o yellow wire".
5.The work during bidding process of highway engineering is analyzed from qualification examination, document preparation, bidding quotation and other aspects. Some strategies are introduced for bid invitation in order to raise the rate to win the bid.
6.Two methods are used to improve the welding quality between cylinder and its seat of shock absorber on CY80 Motorcycle. One is to change the geometrical dimensions and shapes of the weld head and the other is to optimize the welding process. Thus the welding quality is greatly improved,and the qualification rate reaches
7.Abstract: By taking the modification project of hydrogen generation unit in a petrochemical plant as an example, the successful welding of heat-resistance ferroalloy with high Cr-Ni content is presented, including weldability analysis, weld procedure qualification test, weld process measures and quality inspection.
