GENERAL 综述I.1 Scope of Engineering Specification, General Statement 总体说明，本规范适用范围This Engineering Specification is issued to define design factors and performance requirements applicable to the joining of nuts and bolts using the projection welding process. It covers manual and automated projection welding on sheet steel having a minimum of 0.5 mm and a maximum of 3.0 mm thickness. It covers metric dimensions up to M16 and property class 4.8 and 8.8 fasteners, but not fasteners of the property class 10.9.本规范用于规定螺母及螺栓凸焊的设计要素和焊接过程要求，它涉及厚度从0.5~3.0mm的钢板的手工凸焊和自动凸焊。

本规范囊括了公制M16以下的紧固件，其性能等级为4.8和8.8，而不包括性能等级为10.9的紧固件。

This Engineering Specification harmonizes the requirements globally for Ford Motor Company and is applicableto new model programs. 本工程规范对全球的福特公司均有效并适用于新车型项目。

This Engineering Specification does not replace the requirements of the Ford world-wide fasteners standards, which focus on the performance of the fastener itself. Instead, it defines the requirements for the projection- welded joint between the fastener and the base sheet metal. Applications that require special fasteners are not dealt with here and require a case-by-case approval by the appropriate Fastener, Body and Manufacturing Engineers.本工程规范不替代全球通用的福特紧固件标准（该标准主要讨论紧固件本身的性能），而是规定紧固件和板材之间的凸焊接头的各种要求。

采用特殊紧固件的情况不在本规范讨论之内，如有采用需经紧固件工程师，车身工程师和制造工程师逐项批准。

This Engineering Specification is a supplement to the released part drawing, and all requirements herein must be met in addition to all other requirements of the part drawing. Each section specifies the minimum measures necessary for documenting compliance with this specification.本工程规范是所发放零件图纸的补充，除了要满足图纸的要求，也必须满足本规范的要求。

每部分规定了遵从本规范的最基本的措施。

This Engineering Specification is intended to evaluate specific characteristics as a supplement to normal material inspections, dimensional checking and in-process controls, and should in no way adversely influence other inspection operations.本工程规范作为常规的材料检查，尺寸检查和过程控制的说明补充，而决不能反过来影响其它的检查操作。

Preparation and submission of an acceptable control plan are the responsibility of the manufacturing source. The manufacturing source will retain the original control plan and any later revisions per QS-9000 and provide a copy to the design responsible Product Engineering activity.制造资源有义务准备与提交一份可接受的控制计划，制造资源保留原有的控制计划和任何之后经过QS-9000标准的修订版本，并且复制一份给负责设计的工程小组。
