mild steel gas cutting slag:

Oxy-fuel cutting; the basics explained HGG 3D Profiling

This slag has a lower melting point than steel, so the oxygen stream can blow the liquid slag out of the cavity without affecting the non-oxidised solid steel. This exothermic reaction is a continuous process and creates a cut as the torch moves. To keep the exothermic reaction working, the cutting torch keeps the steel heated during cutting.

Flame Cutting (Oxy Fuel Cutting) - A Method to Cut Thick Steel

Flame cutting (also known as oxy fuel cutting), it is to use the heat burned from oxy fuel gas, to cut steel materials or the hard metals to the panels or profiles required. It can cut steel thickness from 1 mm to 1200 mm. And in most cases it used to cut steel plate thickness more than 20 mm, since oxy fuel cutting usually brings big tolerance.

Slag everywhere, HELP!!! : lasercutting

I am trying to create few laser cutting profiles for different mild steel thickness, however i get a lot of slag buildup when I try to cut anything over 5mm. The slag seem to seep back into the cut contour, and sometime seven builds up on top of the surface (gas/slag bubble), and I cant get the part out.

How to troubleshoot cut quality problems – too much dross ...

(Oxygen plasma gas reacts with carbon steel to produce a finer spray of molten metal, each droplet having a lower surface tension. This molten spray is more easily ejected from the kerf). The dross free window is also affected by material type. For instance cold rolled steels cut cleaner than hot rolled and pickled steels cut cleaner than non ...

Oxy-fuel welding and cutting - Wikipedia

Oxy-fuel welding (commonly called oxyacetylene welding, oxy welding, or gas welding in the United States) and oxy-fuel cutting are processes that use fuel gases (or liquid fuels such as gasoline) and oxygen to weld or cut metals. French engineers Edmond Fouché and Charles Picard became the first to develop oxygen-acetylene welding in 1903.Pure oxygen, instead of air, is used to increase the ...

Back to basics: The subtle science of burr-free laser cutting

Jan 25, 2017  Oxygen-cutting carbon steel benefits from higher oxygen gas purity levels. “It has been proven many times that, with both CO 2 and fiber lasers, increasing oxygen global purity to 99.95 percent or above—to 99.98 or 99.99 percent—we can increase the cutting speed in production significantly, sometimes between 30 and 40 percent.”

machining after flame cutting - Practical Machinist

Jul 25, 2014  Mild steel can be carburized, but that's unlikely to happen unintentionally in a flame cutting setup. What many perceive as a hardened edge is simply the scale and decarburization, which can be hard (er) on tools. In contrast, flame cut 4140 alloy steel plate DOES get a hardened edge - somewhere in the 40+ Rc range.

Oxy Acetylene cutting of steel - WeldingWeb

Feb 07, 2021  Re: Oxy Acetylene cutting of steel. Always a good idea to preheat the pipe (any bevel cutting for that matter) by going around once fairly quick. At the very least get it nice and hot (starting to glow) a few inches ahead and then come back and start your cut. Most guys move the torch back and forth to heat the pipe before starting the cut.
