Tungsten Inert Gas Welding Can Achieve the Highest Quality Welds

Murex Welding Products' TIG Welding Guide contains applications of TIG welding and pointers to its successful use.

Of all the arc welding processes, TIG (tungsten inert gas) welding can achieve the highest quality welds and is the most versatile in terms of what can be welded and the position of the welds.

However, quality comes at the expense of time and TIG is generally slower than MIG or MMA welding but, where weld integrity is critical, production engineers are prepared to accept the additional process time.

TIG welding is versatile and can be used with most weldable metals, including dissimilar metals and thicknesses from 0.5mm upwards.

TIG welding machines are available in current ratings from 150A to 350A and can operate at currents as low as 3A for a 150A machine.

TIG machines can be used for brazing and MMA welding.

The most commonly used gas for TIG welding is pure argon.

For thick aluminium and copper, argon/helium would be used for the added heat from the helium.

TIG operatives must use the correct tungsten electrode otherwise problems can be experienced with striking the arc and maintaining a stable arc. Read more...
