Move the torch in a straight line to keep a straight cut and move the torch at a uniform speed at which the flame is cutting through the metal. Chalk line guides may be drawn on the cutting surfaces to mark the cut.
Chat OnlineThis is why stainless steel cut edges benefit from mixtures like F5 and H35 (35 percent hydrogen and 65 percent argon) for the plasma gas and nitrogen as the shielding gas. For systems with advanced mixing capabilities higher levels of hydrogen in the plasma gas mixture are used to cut thick stainless steel.
Chat Online1. Cutting Speed Too Low. An abnormally low cutting speed results in heavy gouging of the cut surface and slag adhering in large globules. Under this condition oxygen and fuel gas are being wasted.. 2. Cutting Speed Too High. An extremely high cutting speed results in heavy lag as shown by the curved lag lines on the cut surface.

Chat OnlinePlasma cutting with pure Nitrogen is a strictly "thermal" process usually used on non-ferrous materials. On carbon steel using nitrogen as the plasma gas more dross is prevalent and nitriding or hardening of the cut edge is common. MSDS Laser fusion cutting
Chat Online(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
Chat OnlineOxy-fuel cutting the basics Before cutting the cutting torch has to pre-heat the steel to ignition temperature at the starting point. At this temperature of around 960°C (depending on type of alloy) the steel has lost protective properties against oxygen and is still solid. Pure oxygen is then directed through the nozzle at the heated area.
Chat OnlineOxy-Fuel Gas Cutting Correct Conditions Bad gouging in the lower half of the cut is caused by molten steel scouring the cut surface and the hot metal and slag that congeals on the underside is always
Chat OnlineWelding and cutting can produce hazards such as sparks spatter radiation (infrared ultraviolet and blue light) slag heat hot metal fumes and gases and even electric shock. Since these hazards may
Chat OnlineSubject-Matter of Oxy-Acetylene Cutting Process In modern steel-age the steel-makers cut Iron and Steel by oxy-acetylene oxy-hydrogen oxy- propane oxy-natural gas cutting blowpipes easily speedily and cleanly. Cutting of metals by means of flame has many advantages over other methods specially when the metal is of irregular shape.
Chat Online(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
Chat OnlineFor cutting steel compressed gas or air is typically supplied by a simple shop air compressor. The actual cutting process entails the creation of an electrical pathway of superheated electrically ionized gas or plasma originating from the torch and jetting through the metal to be cut.
Chat OnlineWith oxy-fuel cutting an oxygen/fuel gas flame preheats the steel to its ignition temperature. A high-powered oxygen jet is then directed at the metal creating a chemical reaction between the oxygen and the metal to form iron oxide also known as slag. The high-powered oxygen jet removes the slag

Chat OnlineFlame 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

Chat OnlineStructural steels are usually gas cut although laser cutting is increasingly used for plate. In gas cutting a flame of fuel gas such as acetylene burning in oxygen heats the area to be cut a stream of oxygen is then injected around the flame which actually burns the steel
Chat OnlineProper gas selection (see Figure 1) is the first step toward success when using plasma to cut stainless steel. Air used as both the cutting and shielding gas is a common choice for fast cut speeds and low
Chat OnlinePropylene is also preferred for flame spray or metalizing cutting thick steel bevel cutting and scrap cutting. Natural gas in an inexpensive gas but has long preheat times and is very slow to cut. In
Chat OnlineThis 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.
