Good welding pool.In welding process, due to reasons such as heat input are improper compared with big or welding procedure, welding deformation easily occurs
With there is residual stress, simultaneously because there is recrystallization and the roughening of heat affected area crystal grain in weld seam and fusion area, cause weldering
Connect heat-affected zone softened, be easily formed the defect such as pore, shrinkage porosite, cause strength of welded joint to be substantially reduced, have a strong impact on component
Serviceability.Research shows, is primarily present following several big difficult point in Welded:
1), welded joints in aluminium alloy soften serious, strength factor is low；
2), aluminum alloy surface is easily generated the oxide-film (Al of infusibility2O3), the welding procedure of high power density need to be used；
3), Welded easily produces pore and fire check；
4), Welded linear expansion coefficient big, be easily generated welding deformation；
5), aluminum alloy heat conductance big (about 4 times of steel), under same weld speed, heat input is than during welding steel big 2
～4 times.
Wherein, welded joints in aluminium alloy produces and softens, and strength factor is substantially reduced, and strength of joint is far below mother metal, causes
Joint performance reduces, thus, limit the aluminium alloy extensive application in Welding Structure to a certain extent.
