适用范围
This document specifies requirements for classification of covered electrodes, based on the all-weld metal in the heat-treated condition, for manual metal arc welding of ferritic and martensitic creepresisting and low alloy elevated temperature steels. This document is a combined specification for classification utilizing a system based upon the chemical composition of the all-weld metal, with requirements for the yield strength and impact energy of the all-weld metal, or utilizing a system based upon the tensile strength and the chemical composition of the all-weld metal. a) Paragraphs and tables which carry the suffix letter “A” are applicable only to electrodes classified to the system based upon chemical composition, with requirements for the yield strength and impact energy of the all-weld metal under this document. b) Paragraphs and tables which carry the suffix letter “B” are applicable only to electrodes classified to the system based upon the tensile strength and the chemical composition of all-weld metal under this document. c) Paragraphs and tables which do not have either the suffix letter “A” or the suffix letter “B” are applicable to all covered electrodes classified under this document. For comparison purposes, some tables include requirements for electrodes classified according to both systems, placing individual electrodes from the two systems, which are similar in composition and properties, on adjacent lines in the particular table. In a particular line of the table that is mandatory in one system, the symbol for the similar electrode from the other system is indicated in parentheses. By appropriate restriction of the formulation of a particular electrode, it is often, but not always, possible to produce an electrode that can be classified in both systems, in which case the electrode, and/or its packaging, can be marked with the classification in either or both systems.

如果这三个问题没把你问蒙圈,证明你是有一定焊接基础的

,其在搭接时最薄可焊到0.4毫米,而大型复杂焊件工作时,由于埋弧焊无法全位置操作,所以二氧化碳焊的高熔敷效率(高于手工焊1-3倍)、大熔深(大于手工电弧焊三分之一)、焊接成本低(焊接综合成本只相当于手工电焊和埋弧焊的一半左右)、高质量焊缝(所有焊接手段中焊缝含氢最低,因此抗拉强度远远高于普通结构焊条,且基本不会产生延迟裂纹)、可方便的进行全位置焊接的特点,已经代替手工电弧焊成为首选方法。...
