Setting Up the Welding Section on Tube and Pipe Mill Lines
Most firms conduct at least a basic mechanical test to insure weld integrity. Others may cut and polish a welded sample and check the weld under a microscope to insure the flow lines and bond is proper and/or add other additional tests such as a tensile pull test. To follow are some causes and solutions for poor weld integrity.

Repair Rebuilding of Mill Rolls Baltimore, MD
Clark Machine was recently contracted by a steel mill for the repair of a series of large mill rolls used in their steel processing operation. Clark specified a multistep procedure for the reconstruction of the mill rolls. Material was added using MIG, FCAW, SMAW welding, followed by milling to required dimensions and additional machining to restore journals and keyways.
Improving Coal Pulverizer Performance and Reliability
The hammers impact on the coal, crushing it against the plates. Further pulverization is achieved as the smaller coal particles are ground through attrition against each other and the grinding face. Vertical Roller Mills This mill uses hydraulically loaded vertical rollers resembling large tires to pulverize raw coal fed down onto a rotating table. As the
COMBUSTIBLE DUST HAZARDS IN THE WELDING AND .
limestone dust is used in coal mines to reduce explosion hazards. However, materials which can burn or corrode in contact with oxygen can form combustible dusts. These "reactive" materials include: metals, plastics, coal and other carbonaceous materials, grains, wood and paper, and many organic compounds such
How to make Damascus Blades
I mainly use a Coal forge and simple Borax (20 mule team, from the laundry dept.) as a flux when I do my pattern welding. Flux helps to keep out the air, which in turn helps to reduce scale. Since scale melts at much higher temperatures than the steel, it can interfere with the welds and it looks terrible.

Another way to make coal burning cleaner is to use flue gas desulfurization systems, which are also known as 'scrubbers.' These systems remove sulfur dioxide from the flue gas. This is an easy term to recall if you remember that the prefix 'de' means to remove, and the term 'sulfur' is found in the word.
Millscale
Jan 26, 2012· Mill scale is a form of oxide, it requires more energy to melt it and consume it in the welding arc than the "pure" metal that is presented to the arc/weld metal. When you weld on cleanly ground metal, especially hot rolled plates or other shapes, the aesthetics and often the mechanics of the weld will be of higher quality.
