General Notes:
1.Service conditions such as immersion in fresh or salt water,exposure to specific chemicals,or asustained high temperature,aluminium welding wire for high heat(over 150F [66℃)may limit the choice of filler metals welding wire aluminium, aluminium welding wire for mig Filler metals ER5183,ER5356 welding rod,ER5556 are not recommended for sustained elevated temperature service.
2.aluminium mig welding wire recommendations in this table apply to gas shielded arc welding processes.For oxyfuel gas welding,only ER1188,ER1100,ER4043,ER4047,ER4145 filler metals are ordinarily used and aluminium welding wire specification.
3.Where no filler metal is listed,aluminum alloy welding wire ,the base metal combination is not recommended for welding
aluminium welding wire gasless.
Notes:
a. ER4145 may be used for some applications to some aluminum alloy welding wire.
b. ER4047 may be used for some applications to some flux cored aluminium welding wire.
c. ER4043 may be used for some applications to some aluminium magnesium welding wire.
d. ER5183,ER5356,or ER5556 may be used to some aluminium welding wire grades.
e. ER2319 may be used for some applications.It can supply high strength when the weldment is postweld solution heat treated and aged.
f. alum.welding wire ER5183,ER5356,ER5554,ER5556,and ER5654 may be used In some cases:(1) improved color match afer anodizing treatment,(2) highest weld ductility (3) higher weld strength.ER5554 is suitable for sustained elevated temperature service.
g. alum welding wire ER4643 will provide higher strength in 1/2 in.[12mm]and thicker groove welds in 6XXX base alloys when postweld solution heat treated and aged.
h. flux core aluminum wire Filler metal with the same analysis as the base metal is sometimes used.The following wrought filler metals possess the same chemical composition limits as cast filler alloys: ER4009 and r4009 as R-C355.0;ER4010 and R4010 as R-A356.0; R4011 as R-A357.0.
i. Mig welding aluminum wire ,Base metal alloys 5254 and 5652 are used for hydrogen peroxide service.ER5654 filler metal is used for welding both alloys for service temperatures below 150F [66°℃].
j. ER1100 may be used for some applications in wire feed welding aluminum.
