Welding Defects

As with most procedural based technical systems, inevitable variability within the process leads to the potential for quality issues and welding is no different in this regard.
Welding defects can be numerous but most commonly it is possible to encounter porosity issues, contaminant entrapment, inadequate shielding, arc related issues to name but a few.

The MURC Process

A number of improvements were identified by some industry leaders in relation to reducing both costs and slag generation in high grade steel production.
The MURC process separates and therefore provides opportunities for optimization in the four principle steel refining processes and in addition specific focus on the converter-type methodology.

Direct-Chill Casting

Since its development and subsequent launch in the 1930’s Direct Chill Casting has become the most widely used semi-continuous casting process for the production of non-ferrous billets and ingots.
The main advantages of DC Casting are that the defects deriving from the process are controllable and effectively limited to localized presence in a narrow layer at the surface of the billet. Continue reading

Metal Vacuum Distillation Process: Part Two

One of the main advantages of the Vacuum Distillation Refining is that it efficiently and effectively removes impurities such as Sb, Bi, Al, Au, Ag, Cu, Si and Fe.
Another possibility using this methodology is to refine specific scrap such as magnesium into very high purity material which can be used in highly specific industrial applications (semiconductor industry in this case).
