stainless steel gas stream flow chart

The inert gas flow which protects the arc zone from the ambient air, enables a very stable arc to be maintained. Depending on the base material, shielding gases consist mainly of mixtures of argon (Ar), helium (He) and hydrogen (H2) (see section 4 'Selection of shielding gases for welding stainless steel'). 70 à 90° 20° Direction of ...

Note that excessive flow rates create turbulence causing air to mix into the gas stream. Using a gas lens is an advantage for TIG because it reduces the tendency for turbulence at higher flow rates. When using gas lenses, the suggested maximum flow rates should allow welding in up to 4-mph draft. Beyond that, a windbreak of some type should be ...

The machine will open gas valve to start flow of shield gas, after a 0.5 seconds pre-flow time to purge air from torch hose the welding output of machine will be turned on and the arc will be started. After the arc is started the output current will increase from the start (min) current to base (main) current in time selected by slope-up.

Flow Rate Calculator. Easily calculate the volumetric flow rate of a pipe (a.k.a. discharge rate) given its dimensions and either a pressure difference between its ends or the velocity of the liquid or gas flowing through it. The flow rate calculator can also calculate the mass flow rate of a fluid given its density is known. Input and output support metric and imperial measurement units.

The main job of the shielding gas is to cover the mouth of the weld and keep it from coming in contact with oxygen and nitrogen and the surrounding air, but these gases also affect the characteristics of the arc itself. The most common mixture of shielding gas is 75% argon and 25% C02. The way you see these percentages on a chart or in articles ...
