High wind velocity can potentially cause porosity in welds by introducing contaminants, such as oxygen and moisture, to the welding area. These contaminants can react with the molten metal and create gas pockets or porosity in the weld bead. It is important to shield the welding area from strong winds or drafts to prevent porosity.
High wind velocity can cause porosity in a weld by disrupting the shielding gas flow around the weld pool. This can lead to oxidation of the molten metal, resulting in the formation of gas pockets or voids in the weld, which is known as porosity. It is important to ensure proper shielding gas coverage and protection when welding in windy conditions to prevent porosity.
big particles=low porosity small particles=high porosity
how do we calculate porosity of ceramic?
Porosity is the formation of bubbles in the weld.
poorly sorted = low porosity well sorted = high porosity
The porosity directly correlates with the permeability because the permeability requires a certain level of porosity for a certain measure of it.
What is porosity ? And how can it affect hair color
No, clay porosity is typically lower than sand porosity. Clay particles are small and tightly packed, leading to lower porosity compared to sand particles, which are larger and have more open spaces between them.
Primary porosity: The initial pore space that forms in rocks during their formation. Secondary porosity: Pore space created by post-depositional processes like fracturing or dissolution. Effective porosity: The portion of the total porosity that allows fluid flow through the rock.

Herringbone porosity refers to a specific type of porosity pattern that resembles the bones of a herring fish. It is commonly observed in materials such as welds, ceramics, and rocks, where the porosity formation is aligned in a repetitive V-shape pattern. This type of porosity can impact the structural integrity and mechanical properties of the material.
