Abstract:

The level of importance of each of the different phases of engineering and manufacturing that in fluence product quality and yield are described in the following pages together with appropriate methods of exercising the necessary controls. The major headings are as follows Engineering, Parts Selection, Manufacturing Aids, Lead Con trol, Weld Schedule Development, Part Handling, Manufacturing Environment, Qualification of Manufacturing Equipment, Process Controls and Quality Control. The level of importance of each of the influencing factors are described by a weighting of 125 points for the most important downward. A listing of paragraphs in declining order is given in the index. Each subject in cludes a weighting factor in a 1 to 5 ranking in order of importance. The weight ranking is applied at each level of indenture so that the final paragraph weighting is the product of the three levels. The highest number being 125 5 x 5 x 5 which represents the highest degree of importance. Each area of responsibility in the manufacture of welded modules is indicted by reference to a number which corresponds to the Block Diagram of a typical Factory. A diagram Figure 0-1 is provided to assist in applying the principles detailed in this handbook. Ac cordingly the weighting index also includes the related blocks of the typical factory for each subject discussed. Author
