根据对Q690材料在焊接液压支架结构件时的加工经验,通过Q690材料的特点简单介绍了Q690材料的焊接工艺。相比于其他材料,低合金钢在焊接中应注意焊前预热、焊后保温及探伤,并提出气温和天气对焊接的影响。为Q690材料的应用提供参考。
According to the Q690 material in the welding of hydraulic support structure of the processing experience, Q690 materials by the characteristics of a brief introduction of the Q690 material welding process. Compared with other materials, low alloy steel should pay attention to welding preheating, welding insulation and flaw detection, and put forward the temperature and the impact of the weather on the welding. Provide reference for the application of Q690 material.
