某重型机械厂房钢吊车梁的制作工艺

Manufacture Process of Crane Beam in a Heavy Mechanical Workshop

结合工程实例,介绍了重型机械厂房钢吊车梁的制作工艺,并针对其中的关键技术,如正确的预热方式和预热温度、合理的焊接程序、多道焊的道间温控及"后热"保温缓冷的"去氢"措施等。

Based on project practice, working process of heavy workshop crane beam is introduced, aiming at the key technology in it, such as the right preheat method and preheat temperature, reasonable welding process, multi-pass welding of between-track temperature control and dehydrogenation measures of after heat preservation, are all detailed discussed.
