Abstract
本发明为一种高效铁粉耐候钢焊条。适用于耐候钢焊接。本发明焊条钢芯为H08A焊丝,药皮成分(重量%)为:CaCO3:2~4,MgCO3:1~3,TiO2:22~28,SiO2:10~15,Mn-Fe:6~10,Ti-Fe:0.5~1.5,W:1~2,Cu:0.8~1.2,稀土:1~2,其余为铁粉。
本发明焊条具有焊接工艺性能好,适用于交、直流两种焊接电源,可平焊、平角焊、横角焊,熔敷效率高等特点。
Description
本发明属于焊接材料领域,适用于制作耐候钢的铁粉焊条。
目前,为了提高焊接效率,国内外都在开发和应用高效铁粉焊条。当焊条的熔敷效率在145%以上时,由于熔敷金属的增加和辅助劳动时间的减少,可使焊接劳动生产率提高一倍以上。但是现已开发和应用的高效铁粉焊条,施焊时产生的焊缝组织不含具有防腐性的合金元素,因而不适用于耐候钢的焊接。通用的耐候钢焊条如J502WCu(符合国标牌号F5003-G)虽然焊缝组织具有良好的抗腐蚀性,但不具有高效之优点。
本发明的目的在于提供一种焊接工艺性能良好的高效铁粉耐候钢焊条。
本发明高效铁粉耐候钢焊条,其特征在于焊条的药皮成分(重量%)为:
CaCO3:2~4, MgCO3: 1~3,
TiO2:22~28, SiO2: 10~15,
Mn-Fe:6~10 , Ti-Fe:0.5~1.5,
W:1~2, Cu:0.8~1.2,
稀土: 1~2,其余为铁粉。
本发明焊条采用水玻璃作粘结剂,将上述成份的药粉混合均匀压涂在H08A焊丝上,生产方法与现有技术相同。
本发明的技术方案是采用W-Cu抗腐合金系和稀土。耐候钢焊条通常选用:Cu-P、Cr-Cu、Ni-Cu、W-Cu、及Cr-Ni-Cu合金系。但是Cu-P系焊条因含P高,韧性较差,焊接性不好;而Cr、Ni是十分贵重的金属材料,势必增加焊条的成本。
本发明选用价廉的W-Cu合金系,焊缝组织抗腐性良好,然而随着W的加入,在焊缝组织中容易发生偏析,低温韧性低且不稳定。加入一定量的稀土,一方面,稀土可对晶间共析物、杂质进行球化、细化,使他们的尺寸减小,形状改变,而且对焊缝组织进行细化。另一方面,稀土提高熔渣的脱氧性,对Mn元素的过渡起到一定保护作用,增加焊缝组织中的Mn含量。因而,可使焊缝金属的低温韧性得以提高,且抗腐性亦有改善。随着稀土的加入,熔渣的理化性能有一定的改变,焊条的工艺性能明显好转,形成脱渣容易,飞溅小、成形美观、再引燃容易等优点。
本发明焊条可采用交直流两种焊接电源,适用于平焊、平角焊和横角焊,熔敷效率高,焊接生产率高。适用于耐候钢焊接。
实施例:
按照本发明药皮成分范围,配制两种焊条,具体配方如下
表1焊条药皮成分
CaCO3 | MgCO3 | TiO2 | SiO2 | Mn-Fe | Ti-Fe | W | Cu | 稀土 | 铁粉 | |

2 | 3.8 | 1.5 | 24 | 13 | 7 | 1 | 1.6 | 0.9 | 1.8 | 余 |
配好的药粉加水玻璃粘结剂混合均匀后压涂Φ4mm的H08A焊丝上,焊条外经Φ8.2mm。经48H阴干后,烘烤。通过在耐候钢板(09CuPTiRe)上施焊表明。本发明焊条焊接工艺性能良好,电弧稳定,脱渣容易,焊道平滑,成型美观。化学成分及熔敷效率见表2,抗腐蚀性与耐候钢母材相当。
