Where can I find information regarding porosity in aluminium welds?

TWI Frequently asked questions

By: Andrew Low

The following list of references provides information on various aspects of porosity in aluminium welds, such as:

• welding parameters affecting porosity formation
• effect of porosity on mechanical properties - see also FAQ: What is the influence of porosity on the mechanical properties of aluminium welds?
• how to avoid the formation of porosity - see also FAQ: I keep getting porosity when welding aluminium. Any advice?
• allowable porosity levels

See also:
What is porosity and how can it be prevented?
How can weld porosity be detected and how can it be remedied?
