摘要
从前期准备、下料、组对、焊接、防腐等几个方面阐述了大型钢结构箱形井架的制作工艺过程及质量控制措施,该工艺过程既保证了井架的整体拼接尺寸,同时保证了井架的焊接质量。
The manufacture process and the quality control measure of large-scale steel box headframe are elaborated in the aspects of preparation, blanking assemblage welding and anticorrosion. This technological process both guaranteed the splicing size and welding quality of headframe.
