argon
compressed argon gas and liquid argon in a variety of purities and in various modes of supply around the world thanks to our network of storage and transfill facilities.
flame or oxy-fuel gouging
flame gouging is a variant of conventional oxy-fuel gas welding. oxygen and a fuel gas are used to produce a high temperature flame for melting the steel. when gouging, the steel is locally heated to a temperature above the 'ignition' temperature (typically 900°c) and a jet of oxygen is used to melt the metal - a chemical reaction between pure oxygen and hot metal. this jet is also used to blow away molten metal and slag. it should be noted that compared with oxy-fuel cutting, slag is not blown through the material, but remains on the top surface of the work piece. the gouging nozzle is designed to supply a relatively large volume of oxygen through the gouging jet. in oxy-fuel gouging, equal quantities of oxygen and acetylene are used to set a near-neutral preheating flame. the oxygen jet flow rate determines the depth and width of the gouge.
plasma arc gouging
the use of the plasma arc as a gouging tool dates back to the 1960s when the process was developed for welding. compared with the alternative oxy-fuel and manual metal arc gouging techniques, plasma arc has a needle-like jet which can produce a very precise groove, suitable for application on almost all ferrous and non-ferrous materials. plasma gas can be argon, helium, argon/hydrogen, nitrogen, or air.
manual metal arc and air carbon arc gouging
in these processes an electrical arc is generated to melt the material. other techniques like special electrodes or a jet of compressed air are used to blow away the molten material. no specific high purity or compressed gases are needed in these processes.

“i use high-pressure gas cylinders and am concerned about safety. is there a better way?”
traditionally, high-pressure gas cylinders have been the supply mode for users in the low to medium volume range. air products cryoease® microbulk service consolidates your gas supply to a centralized system eliminating the need to handle cylinders and ensures the right gas is delivered to your use point. further benefits of the cryoease® microbulk service include decreased exposure to high-pressure containers and reduced traffic congestion with less frequent supplier deliveries. air products developed the microbulk supply option as a cost-effective, reliable alternative to high-pressure cylinders for nitrogen, argon, oxygen and carbon dioxide supply. in addition to efficient and flexible storage systems, innovative piping solutions are available to help you have a smooth transition from cylinders to microbulk.
cryoease® microbulk solutions
cryoease® microbulk technology is a modern concept where your gas is supplied by filling on-site vs. the traditional method for smaller volume usage, where gas is supplied by swapping full for empty cylinders and dewars. cryoease® microbulk supply features specially designed trucks with integrated controls and flexible storage tank options. end usage can be provided as pure gases, cryogenic liquids or gaseous mixtures via a blender installed at your site.
