本标准规定了根据AS2885设计和建造的壁厚小于3.2mm的碳钢和碳锰钢管道施工和维护焊接的最低安全要求、焊接耗材、焊接准备、焊接工艺、焊接程序和人员资质，以及制造和检查要求。1.不排除焊接耐腐蚀合金钢管道，或标称厚度小于3.2mm的管道，但本标准未明确涵盖。必须特别考虑此类管道的焊接。

This Standard specifies the minimum requirements for safety, welding consumables, weld preparations, welding processes, qualifications of welding procedures and personnel, and fabrication and inspection requirements for the construction and maintenance welding of carbon and carbon-manganese steel pipelines down to 3.2mm wall thickness designed and constructed in accordance with AS2885.1. The welding of corrosion resistant alloy steel pipelines, or pipelines with nominal thicknesses less than 3.2mm, is not precluded, but is not expressly covered by this Standard. The welding of such pipelines has to be given special consideration.
