Modern landing gear of aircraft had the characteristics of high life and high reliability,which made new mate-rials,especially ultra-high strength steels and titanium alloy,was widely used in landing gear,hereinto,A100,300M and AF1410(16Co14Ni10Cr2Mo)ultra high strength steels were particularly outstanding.This kind of ultra-high strength steel was usually machined in the way of die forging parts in the landing gear system,and because of poor weld ability of these ul-tra-high strength steels,few were welded.We mainly discussed the welding process and quality control of large thickness of AF1410(16Co14Ni10Cr2Mo)steel.
