灰铸铁的焊接性及焊接工艺研究摘 要：灰铸铁这个东西有非常好的可塑性、他的抗震效果也是非常的好、还非常的耐磨、在加工上很方便、这个材料它还特别的敏感，具备很多的好的特性，这个材料在工业生产中用的特别的多。专门分析这个材料的焊接也能带来很大的收益。要是这个材料的焊接不好会给我们带来不利的影响。我们国家一些工人能很专业的焊接这种材料，要是对这种材料不是很熟悉或者焊接技术不行，这种材料焊接好了以后会裂开。因为某些因素的制约，在这里把灰铸铁的一些特点都列取出来、还有灰铸铁的一些缺点也列取出来防止焊接出现裂缝。这样能够帮人们理解灰铸铁以及它的焊接要点。灰铸铁的焊接注意点主要考虑它的内部成分。关键词：灰铸铁 焊接性能 焊接缺陷 冷却速度 焊接 Weldability and Welding process of Gray cast IronAbstract:Gray cast iron this thing has very good plasticity, its seismic effect is also very good, but also very wear-resistant, in the processing of very convenient, this material it is also particularly sensitive, has a lot of good characteristics, This material is used very much in industrial production. Special analysis of this material welding can also bring great benefits. If the welding of this material is not good, we will be adversely affected. Some workers in our country can weld this material professionally. If the material is not very familiar with it or the welding technology is not good, the material will split when it is welded. Due to the restriction of some factors, some characteristics of gray cast iron are listed here, and some shortcomings of gray cast iron are also listed to prevent cracks in welding. This helps people understand gray cast iron and its welding points. The welding attention point of gray cast iron is mainly concerned with its internal composition.keyword: gray pig iron welding performance weld defect weld目录..........................................................................
