metal penetration

For normal thicknesses, a root gap of 1.5mm is recommended to ensure satisfactory weld metal penetration.

An alternative form of metal penetration into the mould known as veining is caused by cracking of the sand.

Up to 2% of iron oxide powder can be used to prevent mold cracking and metal penetration, essentially improving refractoriness.

The second type of defect is metal penetration, which is when the liquid metal penetrates into the molding sand.

Mould dressings are not normally required as the alumina skin minimises metal penetration and aids the flow of metal through the mould.

Sometime and somewhere, he told himself as he lifted the scanner and keyed for the metal penetration setting, everything has to happen for the first time.

In metallurgy a veining (or finning) is the occurrence of a sheet like casting defect, produced by molten metal penetration into a sand casting mould.

This cored wire is more expensive than the standard solid wire and can generate fumes and/or slag, but it permits even higher welding speed and greater metal penetration.

Up to 5% of reducing agents, such as coal powder, pitch, creosote, and fuel oil, may be added to the molding material to prevent wetting (prevention of liquid metal sticking to sand particles, thus leaving them on the casting surface), improve surface finish, decrease metal penetration, and burn-on defects.
