关于焊接结构钢的最佳参考——2002 D1。1钢结构焊接规范。1928年以来的行业权威，D1。1提供了焊接碳钢和低合金钢结构的信息和要求。焊工、工程师、设计师、建筑师、制造商以及依赖焊接钢结构完整性的人员将在D1中找到关于焊接设计、静态和循环加载连接、管状和非管状连接、资格预审、测试程序等问题的答案。 1.具体章节包括:一般要求焊接连接设计焊接连接的具体焊接要求制定焊接工艺规范非破坏性试验加强和修复现有结构的方法扩展责任增加了新的责任章节（1.4），其中描述了工程师、承包商、，以及承包商和验证检查员。已包含注释，以详细说明和演示代码文本。 定义了一种新类型的承包商，即原始设备制造商，以描述单一承包商承担工程师责任的情况。本规范始终承认，工程师有权添加、修改或删除任何规范规定。本授权旨在为通用D1的应用提供灵活性。1.工业应用全景图文档。对于某些应用程序，规范规定可能是保守的，但对于其他应用程序，则不是。 也可能存在规范未解决的情况，工程师可能需要在合同规范中包括这些情况。

The best reference there is on welding structural steel -- the 2002 D1.1 Structural Welding Code for Steel. An industry authority since 1928, D1.1 provides the information and requirements for welding carbon and low-alloy steel structures. Welders, engineers, designers, architects, fabricators, and those who depend on the integrity of welded steel structures will find answers to questions on weld design, statically and cyclically loaded connections, tubular and nontubular connections, prequalification, testing procedures and more in D1.1.Specific sections include:General requirementsDesign of welded connectionsSpecific welding requirements for connectionsDevelopment of welding procedure specificationsNondestructive testingMethods to strengthen and repair existing structuresExpanded ResponsibilitiesA new section on Responsibilities (1.4) has been added that describes the responsibilities of the engineer, contractor, and contractor's and verification inspectors. Commentary has been included to elaborate on and demonstrate the code text. A new type of contractor, the original equipment manufacturer, is defined to describe situations where a single contractor assumes the responsibilities of the engineer.The Code has always recognized that the engineer has sole authority to add to, modify, or delete any Code provision. This authority is intended to provide flexibility when applying the generic D1.1 document to a panorama of industrial applications. Code provisions may be conservative for some applications, but not for others. There may also be situations the Code does not address, which the engineer may need to include in the contract specifications.
