大庆油田共有5000多名焊工,每年完成6万吨钢材的焊接工程,产值约1亿元左右。在油田开发建设中,对焊接结构的安全性有着特殊的要求,因此,如何提高焊接质量,如何提高焊工的技能和素质,一直是大庆油田所探索的重要课题之一。最近两年,在中国机械工程学会焊接学会的帮助下,按照联邦德国标准 Daqing Oilfield a total of more than 5000 welders, each completed 60,000 tons of steel welding project, the output value of about 100 million yuan. In the development and construction of the oilfield, there are special requirements on the safety of welded structures. Therefore, how to improve the welding quality and how to improve the skills and qualities of welders has always been one of the important topics explored by Daqing Oilfield. In the past two years, with the help of China Society of Mechanical Engineering Welding Society, in accordance with the Federal German standards
