Welding of nickel alloys by Inconel
Are you interested in welding nickel alloys by Inconel from the supplier AvecGlob? Here you will find interesting information on this topic /
Welding electrodes made of Inconel alloy — properties
The alloy is used for arc welding of nickel and steel, nickel alloys among themselves, as well as alloys of the Monel 400 type with carbon steels and stainless steels. carbon steel; stainless steel to carbon steel. Alloys of this group are used in the range of welding wire for welding of nickel alloys and Inconel 600.
In all positions, the dimensions of the 3/32 and 1/8 diameter electrodes can be used, while the larger diameters of 5/32 and 3/16 are used for the horizontal position of the articles to be welded together.

Features of Inconel welding
Most welding methods are determined by the two main properties of nickel alloys — their low thermal conductivity, and the slow formation of a bath with a liquid metal. Low thermal conductivity means that heat does not dissipate easily. Another way to say that heat is very easy to grow. Therefore, when welding Inconel it is necessary to use cooling pads, which are located on the opposite side of the welding electrode.
Slow melt formation is eliminated by using an argon jet that covers the weld zone. This keeps the temperature of the welding electrode in the right range, and allows the use of comparatively small welding currents in Inconel welding. As a result, the deformations of the welded parts in the zone of the finished weld are also reduced.
Welding using the Inconel 713 and Inconel 718 alloy is used in the aerospace industry for the welding of turbine engine blades, their bodies and compressor blades. When welding structures operating in higher temperature zones, a welding wire made of Inconel 625 alloy is used.
