Recommended gas pressure - Miller Welding Discussion Forums

Apr 11, 2011 · We get many questions about setting MIG gas pressure. Unlike with oxyfuel welding with MIG (or TIG) “flow” is set NOT pressure. Here is why: Having been in the welding business for over 40 years and having managed an R&D lab for a major industrial gas company, setting the proper gas “flow” is not well documented.

What kind of pressure regulator is used in welding?

These gases cannot use at this high pressure for welding works, so a pressure regulator is used between the flow. It supplies oxygen at a pressure of about 70 – 130 Kn/m2 and gas at 7 – 103 Kn/m2 to the welding torch. The torch assembly consists of the handle Oxygen and fuel gas valves and the mixing chamber.

What are the safety features of welding pressure gauges?

In order to reduce the hazard potential for the application, various safety features of welding pressure gauges can be used, such as: Possible placements of blow-out flaps integrated into the case back. In the event of a failure the gas can thus escape out of the back.

Advances in Gas Pressure Welding Technology for Rails

Gas pressure welding is accomplished by butting work pieces together, applying a suitable amount of axial pressure, and heating the joining area with an oxygen/acetylene flame to about 1,200° C, until the upsetting amount reaches a predetermined value (see Fig. 1). This welding method does not use heavy equipment, and produces highly reliable joints that are about as strong as the work pieces being jointed together.
