One of the main reasons as to why the Inconel 718 square bar was developed was to enable good weldability characteristics amongst the various Inconel grades. Some Inconel grades such as Waspalloy and X-750 prove difficult to weld
That’s where Inconel 718 hex bar steps in. Inconel 718 does not pose problems such as difficulty in welding due to cracking as well as segregation of alloying elements in the heat-affected zone in the microstructure. Therefore, welding procedures such as the gas tungsten arc welding and electron beam welding techniques can be used to weld a UNS N07718 bar. In gas tungsten arc welding or what is shortened as GTAW, a non-consumable tungsten electrode can be used to produce the weld on these ASTM B637 round bars.
Which is why the gas tungsten arc welding technique is also referred to as a tungsten inert gas welding or TIG welding. Since the Inconel 718 rod is also used by the aerospace industry, it is only fitting that the gas tungsten arc technique be used to weld Inconel 718 components in this industry. However, it cannot be undermined that the high quality welds can be performed on the Inconel 718 flat bar with the use of this technique.
Another reason why our clients prefer combining the gas tungsten arc welding technique with an Inconel 718 round bar is that both the weld area as well as the electrode are protected from oxidation or any other forms of atmospheric contamination. This is practised by use of an inert shielding gas such as argon or helium along with the use of a filler metal, that is a typical feature of the gas tungsten arc welding technique.

The nickel alloy 718 is tested for notch rupture life and rupture ductility. These are measured with tensile and yield strengths. The bars have minimum yield strength of 987MPa and minimum tensile strength of 1100MPa. But tests are necessary to confirm that the products meet the standards specified. The bars undergo stress-rupture tests, transverse tests, short transvers tests, rotating beam fatigue tests, Krouse test and others. Some tests are mandatory while others are optional according to the customer. The ends of the bars are attached to two pulling components and are pulled to test at which point they break to calculate the ultimate tensile strength. Each of the tests have different procedures to be carried out to get the results.
