low alloy steel tanks porosity

You can machine it,but can you weld it?

The weld metal's low-hydrogen characteristics will reduce the formation of hydrogen sulfide porosity,and the basic slag system reduces the weld metal's sulfur and phosphorus content.Low welding currents can help minimize dilution with the base metal.But there is no guarantee that these precautions will eliminate the problem.What's the Difference in Gas and Shrinkage Porosity?But this definition does not describe or give direction on the root cause of porosity.Casting porosity can be caused by gas formation or solidification shrinkage while the metal is a liquid.If a casting needs to be pressure tight,then the porosity can allow gas and fluids to seep from the part.In addition,the porosity can weaken the casting.What Causes Porosity in Metal? J.F.Heat Treating Inc low alloy steel tanks porosity#0183;To avoid porosity in future metal alloy castings,you should work with your alloy suppliers to ensure that you are receiving the highest possible quality materials for all of your castings.Additionally,you may want to consider melting down your raw materials in a vacuum,so as to prevent gas porosity,and to keep impurities from entering the
