1 范围
本标准规定了焊接结构的尺寸(线性尺寸和角度尺寸)公差及形位公差,这些公差分四个等级,适用于普通制造精度。公差等级的选择应当满足实际需求。
本标准规定的一般尺寸公差和形位公差适用于焊件、焊接组装件和焊接结构。复杂的结构可根据需要做特殊规定。
本标准给出的这些技术要求以GB/T 4249规定的独立原则为依据,即每个尺寸和形状、位置要求均是独立的,应分别满足要求。
仅标注线性尺寸和角度尺寸或形位说明,未单独标注公差的工艺文件,如果没有一般的公差参照说明应视为不完整,但临时尺寸除外。

1 Scope
This standard stipulates dimension (linear dimension and angular dimension) tolerance of the welded construction as well as geometric tolerance, these tolerances can be classified into four grades, and they are applicable to common manufacturing accuracy. Selection of tolerance grade shall be in accordance with the practical requirement.
General dimensional tolerance and geometric tolerance stipulated in this standard are applicable to weldment, welding assembly parts, and welded construction. Complicated structure may be made with special stipulation as required.
These technical requirements stipulated in this standard shall base upon the independent principle stipulated in GB/T 4249, that is, each dimension, shape and status requirement is independent, they shall meet the requirements independently.
Technological documents shall only be labeled with linear dimension and angular dimension or geometric illustration, but not solely labeled with tolerance shall be regarded as unsoundness if there is no general tolerance referring instructions, excluding the temporary dimension.
2 Normative documents
Articles of the following documents cited by this standard become the articles of this standard. All the normative documents noted with date, their subsequent modified lists(excluding errata content) or revised editions are not applicable to this standard, however, it is encouraged for the parties make an agreement to study whether the latest editions of these documents are usable. All the latest editions of the normative documents without date are applicable to this standard.
