钻井工具切削层的焊条焊接

Welding Drilling Tool Cutting Structure with Composite Rod

 

(浦贤科技公益论坛--第22期)

 

内容摘要:

Abstract: Oil well drilling tools use different cutting structures, from tungsten carbide to artificial diamond. The design to attach the cutting structures to the deploying structure steels usually calls out brazing or welding process. This presentation discusses one way of generating a cutting structure. Composite rod offers a convenient way for easy application of tungsten carbide. The welding process and the consumable are discussed, followed by techniques to attach carbide onto steels, with typical welding conditions and certain examples of techniques. The qualifications of procedure and personnel is briefly discussed at the end.

油井钻井工具采用不同的切削结构,从碳化钨到人造金刚石不等。将切削结构连接到结构钢上的设计,通常要求采用钎焊或焊接工艺。本报告讨论了一种制造切削结构的方法。复合焊条为碳化钨的便捷应用提供了一种途径。报告中探讨了焊接工艺和焊接材料,接着介绍了将碳化物附着到钢上的技术,包括典型的焊接条件和一些技术实例。最后简要讨论了焊接工艺评定和人员资质问题。
