Why Aluminum Welding Is Difficult? Aluminum is a common type of metal used in fabrication.

However, the same traits that make aluminum desirable can also make it tricky to work with.
2021-11-18€luminum has one property that makes welding this metal so difficult: as soon as aluminum is exposed to the ambient air, it forms a wafer-thin layer of aluminum oxide. And it is this layer that gives the metal its unmistakable silver-gray appearance. But it is also makes the aluminum corrosion-resistant to water, oxygen and even many chemicals.

These aluminum alloys can be difficult to arc weld without encountering problems during and/or after welding. These problems are usually associated with cracking, most often, hot cracking and on occasion, stress corrosion cracking (SCC). The aluminum alloys that fall into this difficult-to-weld category can be divided into different groups.
