Remedies to prevent slag inclusions -
Avoid atmospheric contamination using proper welding procedure e.g. adequate Shielding Gas
Proper removal of slag from weld bead surface
using wire brush
Redesigning the weld joint to permit sufficient space for manipulation of the puddle of molten weld material
The following techniques can be used to prevent slag inclusions: Use welding techniques to produce smooth weld beads and adequate inter-run fusion to avoid forming pockets to trap the slag. Use the correct current and travel speed to avoid undercutting the sidewall which will make the slag difficult to remove.
Industrial diamonds can appear cloudy and gray, because of their flaws and inclusions.
An Ash Hopper can be one of two things: 1) ash hoppers were used to funnel the lye out of ashes to make soap. (before soap came out of fancy factories, like it does today, and had to be made at home) The ashes had to have water run through them to remove the lye, so ash hoppers were enclosed, and they were "V" shaped to control where the lye went. 2) ash hoppers are can be used to collect the ashes and slag from steam generating coal powered boilers. Without Ash hoppers, a furnace would get clogged with coals during use, and become inoperable. This type of ash hopper is usually water cooled to prevent overheating from being under the furnace, and to help ash and slag leave the system at a safer temperature. Hope this helps!
Iron is refined by a blast furnace. A furnace is filled with iron ore, coke (which is charcoal made from coal) and limestone. Huge amounts of air are blasted into the furnace, the calcium from the limestone combines with silicates (which are minerals containing silicon and oxygen) to form slag (which is run off ore from the furnace). A layer of liquid iron collects under the slag, at the bottom of the furnace. The liquid iron is periodically let out to cool. Charlie
Advantages Can be used to weld almost any metal as well as dissimilar metals. Gives very good quality welds (structurally and appearance) No slag involved Disadvantages Slow requires high skill to master

Slag inclusions are nonmetallic solid material entrapped in weld metal or between weld metal and base metal. Slag inclusions are regions within the weld cross section or at the weld surface where the once-molten flux used to protect the molten metal is mechanically trapped within the solidified metal. This solidified slag represents a portion of the weld's cross-section where the metal is not fused to itself. This can result in a weakened condition which could impair the serviceability of the component. Inclusions may also appear at the weld surface. Like incomplete fusion, slag inclusions can occur between the weld and base metal or between individual weld passes. In fact, slag inclusions are often associated with incomplete fusion. Daniel

Defects can be varied and classified as critical or non critical. Porosity (bubbles) in the weld are usually acceptable to a certain degree. Slag inclusions, undercut, and cracks are usually non acceptable. Some porosity, cracks, and slag inclusions are visible and may not need further inspection to require their removal. Small defects such as these can be verified by Liquid Penetrant Testing (Dye check). Slag inclusions and cracks just below the surface can be discovered by Magnetic Particle Inspection. Deeper defects can be checked thru X-raying.
Coke is not used to oxidize the slag . It is carbon that is used to oxidize slag.
its still called slag
Inclusions - 2008 was released on: USA: 2008
the cytosol, the organelles, and inclusions
waste slag from blast furnaces is used for road surfacing.
It is a hammer with a flat broad head for knocking slag off.
Welder slag is a byproduct resulting from the welding process, often forming a layer on top of the welded joint. It consists of the residue from the flux used in the welding rod or wire, which helps protect the weld pool from impurities and contaminants while it cools. Slag is typically removed after welding to inspect the quality of the weld and ensure proper fusion.
Slag lines are when a girl wears makeup and there is a ring around her face where her foundation hasn't been put. That is called a slag line.
