Porosity is a weld discontinuity that is not as detrimental to structural integrity as cracks, undercut, overlap and lack of fusion. However, it is unsightly and when painted it becomes an eye sore. Because it does not have sharp ends, porosity does not propagate like a crack. The reason for limits to the amount of […]
Welding is a very complicated industrial process with many different variables. Because of this there are an innumerable amount of problems we can experience when we weld. From porosity and spatter to cracked welds, welding problems cost us a lot of money. In some cases welding problems are severe enough to cause significant delays adding […]
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 […]
