The ability to develop welding procedures for aluminum and aluminum alloys coupled with the ability to weld these alloys is becoming even more important for fabricators. Whether it is a job shop producing different products every day or a firm that specializes in a single product, the ability to fabricate out of aluminum is necessary. […]
Welding aluminum should not be complicated. That is, if you are welding 6061-T6 (very common) with ER5356 or ER4043 filler metal. Although this alloy is still susceptible to cracking, other aluminum alloys are much more prone to cracking. Below are 6 factors that affect cracking susceptibility when welding aluminum alloys. Thermal stresses: Aluminum has […]
If you have welded aluminum you know that it behaves considerably different than steel. Other than the strength difference and general appearance, there are four physical characteristics of aluminum that make it weld completely different than steel. These are: High thermal conductivity High solidification shrinkage High hydrogen solubility Oxide coating When welding aluminum it is […]
