冷作装配的工艺特点：由放样与下料、成形、装配以及变形矫正等模块组成，主要内容涉及桁架放样、柱形体展开放样、锥形体展开放样、过渡接头展开放样、板料下料、板料滚弯成形、板料压弯成形、容器结构装配、板架结构装配、桁架结构装配、钢板条变形手工矫正、焊接工字梁变形矫正以及筒体结构焊接变形矫正。每个模块下有若干教学任务，包含了任务提出、任务分析、相关知识、任务实施、任务评价、思考与练习等教学环节。
冷作工艺学就是冷作的工艺流程.比如一个反应釜，工艺流程是下料，压封头，卷筒身，打坡口，组装焊接，安装搅拌，试压。具体的工艺流程是把这些步骤细化，所以这就需要制作冷作工艺的要对冷作很熟悉，要深入具体的车间工作，才能编制出合理的完整的冷作工艺。
冷作工又称铆工，有人也形象地说它是“铁裁缝“。工作就是把各种型材。板材按照图纸和技术要求，做成产品。这个工作费心又费力，你要有精神准备，文化课要求初中代数，几何要学好，基础课如机械制图，材料与热处理必须重视，再就是冷作工艺学专业课如展开，放样，下料。校正，成型，装配一定得用心学习。还有因为它和焊接相关，就要求有一定焊工工艺知识和掌握一定焊工操作技能，再就是这个工种实践性强，在具体作业时会碰上各种各样的问题，要会灵活处理，很讲究实际经验，所以，在铆焊行业内有“铆工要老，焊工要小”的说法。
冷作用的材料有金属材料和非金属材料两大类，在金属材料中应用最广的是钢。
