Plasma Cutting Stainless Steel Fumes

Welding is the occupation most likely to result in this condition but plasma fumes and laser cutting fumes can also cause it.

Plasma cutting stainless steel fumes.

This document does not deal with uv hazards. Thermit welding uses a chemical reaction to produce intense heat instead of using gas fuel or electric current. An inert gas is blown at high speeds through a nozzle. Oxy fuel and plasma cutting along with brazing are related to welding as they all involve the.

Fume associated with welding and cutting stainless steels fume associated with welding stainless steel. The plasma cutting processes used to cut mild steel stainless steel and other metals generate fine particulate dust and fumes that can be harmful to workers machinery and electronics if not properly controlled. Stainless steel fumes will contain more chromium and nickel than mild steel and both of these metals are toxic. Using a plasma torch to cut metal creates metal dust smoke and fumes that are unhealthful to breath see reference 3 subhead clear the air.

Because it s a thermal cutting process it produces plasma cutting smoke. Cutting stainless steel with a plasma cutter. Iron steel cast iron and copper. Cutting of stainless steel is potentially the most hazardous as the fumes will contain chromium and nickel.

A exhaust channel the of fumes and oxides in different cutting cutting were in 8 mm mild air and oxygen and 8 and 35 mm with nitrogen all of 200 as the cutting 2 7 and. 14 the nature of fume depends upon the metal being cut and upon any coatings. Fume is generated by arc welding processes used for welding stainless steels both the flux shielded processes manual metal arc and flux cored arc and the gas shielded processes tungsten inert gas and metal inert active gas. This is particularly true for metals coated with certain materials such as hexavalent chromium a coating used in metal finishing to prevent corrosion on stainless steel and other metals.

Plasma arc cutting of austenitic stainless steel alloys produces a haz characterized by a thin layer of resolidified metal adhered to the cut edge. The type of chromium released is called hexavalent chromium or hex chrome which is a highly carcinogenic gas with links to health conditions such as cancer and respiratory problems. The hidden dangers of plasma cutting smoke. It is also a hobby for many metal cutting enthusiasts.

Little or no solid state phase transformation is observed in the microstructure. Does plasma cutting produce hex chrome plasma arc cutting of stainless steel will produce hexavalent. Pressure welding uses heat along with impact type pressure to join the pieces. Plasma cutting of stainless and mild steel institute of fröjd.

The thickness of the resolidified layer generally is in the 10 to 30 m range less than 0 001 inch. Plasma cutting is one of the most popular processes for cutting steel and other metals in many manufacturing shops.
