Porosity is the formation of bubbles in the weld.
Here this is an example one : This is applied to the wood before staining and reduces the porosity of the wood.

Porosity refers to the amount of empty space that is between particles of material. When something has a low porosity, it does not have much of this space between its particles.
Porosity refers to the amount of pore space in a material, while permeability is a measure of how easily fluids can flow through a material. High porosity indicates more space for fluids to be stored, while high permeability indicates easy flow of fluids through the material.
Porosity refers to the empty spaces or voids in a material, while permeability is the ability of a material to allow fluids to flow through it. Higher porosity means more empty spaces, but that doesn't always translate to good permeability; permeability also depends on the connectivity of these pores.
Porosity refers to the percentage of open space between individual rock particles in a rock layer. This space can be between grains or within the cracks or cavities of the rock.
If you were to graph particle size and porosity, it would be a constant slope (horizontal line).Porosity is not affected by particle size.
high porosity
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.
Permeability refers to the ability of a material to allow fluids to flow through it, while porosity is a measure of the empty spaces (pores) within a material. In other words, permeability describes how easily fluids can move through a substance, while porosity describes the amount of open space within that substance.
"Porosity" can be used to refer to voidage of a granular material. Pporosity could also denote the relative volume of pores, cracks and spaces in the solid body, while voidage deals exclusively with the amount of spaces between particles in relation to the overall volume occupied by the granular material. Porosity is measure of void spaces in a material.voidage means the relative amount of space between materials that are tightly packed ..........
big particles=low porosity small particles=high porosity
Porosity refers to the amount of pore space within a material, while permeability refers to the ability of fluids to flow through that material. Materials can have high porosity but low permeability if the pore spaces are not interconnected or are blocked, which would inhibit fluid flow. Conversely, materials with high permeability typically have interconnected pore spaces that allow fluids to flow easily.
The porosity of silt can vary, but generally falls between 35-50%. Porosity represents the percentage of void space in a material where water and air can flow, making it an important factor in soil moisture retention and permeability.
