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WeldabilityandWeldingprocessofGraycastIronAbstract:Graycastironthisthinghasverygoodplasticity,itsseismiceffectisalsoverygood,butalsoverywear-resistant,intheprocessingofveryconvenient,thismaterialitisalsoparticularlysensitive,hasalotofgoodcharacteristics,Thismaterialisusedverymuchinindustrialproduction.Specialanalysisofthismaterialweldingcanalsobringgreatbenefits.Iftheweldingofthismaterialisnotgood,wewillbeadverselyaffected.Someworkersinourcountrycanweldthismaterialprofessionally.Ifthematerialisnotveryfamiliarwithitortheweldingtechnologyisnotgood,thematerialwillsplitwhenitiswelded.Duetotherestrictionofsomefactors,somecharacteristicsofgraycastironarelistedhere,andsomeshortcomingsofgraycastironarealsolistedtopreventcracksinwelding.Thishelpspeopleunderstandgraycastironanditsweldingpoints.Theweldingattentionpointofgraycastironismainlyconcernedwithitsinternalcomposition.keyword:graypigironweldingperformancewelddefectweld目录.............................................................................................................................................................4.........................................................................................................................5.......................................................................................................................................................5...............................................................................................................................7...............................................................................................................................7.............................................................................................................9..............................................................................................................................................10..................................................................................................................10.......................................................................................................13..............................................................................................................................................13......................................................................................................................................................16.................................................................................................................................................................20.............................................................................................................................................21..........
