What uses a low open circuit voltage to start the arc? Torch: A device used in the TIG (GTAW) process to control the position of the electrode, to transfer current to the arc and to direct the flow of the shielding gas. Touch Start: A low-voltage, low-amperage arc starting procedure for TIG (GTAW). How does […]

What is tensile strain at yield?
What is tensile strain at yield? Tensile Strength. Yield Strength is the stress a material can withstand without permanent deformation or a point at which it will no longer return to its original dimensions (by 0.2% in length). What is the strongest type of fabric? Of the natural fabrics, silk was the strongest, and wool […]
What do mud cracks indicate?
What do mud cracks indicate? What do mud cracks tell about the environment of deposition of a sedimentary rock? They indicate an environment in which sediment got wet and then dried out. Such an environment could be a flood plain, or tidal flat. What do mud cracks and ripple marks indicate about the geologic past? […]
How do you calculate dry solids?
How do you calculate dry solids? Divide the mass of solids by the total mass of the solution, and then multiply the result by 100 to calculate the percentage of solids by weight. In this example, (17/167) * 100 = 10.18 percent. What is meant by volatile solids? Volatile solids are a substance that can […]
