Combine this with the fact that a person is holding a very hot welding device thats partially melting a super heat-resistant metal, and you have a recipe for disaster. Using an automated welding machine for welding Inconel is the best choice because:It Increases Safety. Characterization of microstructure and mechanical Interface microstructures showed the formation of secondary phases at the heat-affected zone (HAZ) of Super Ni 718 alloy and delta ferrite colonies at the HAZ of AISI 316L. It was witnessed from the weld microstructures that the deleterious phases were suppressed or controlled while using these filler wires for joining the bimetals.
Alloy 718. Alloy 718 is a high-strength, corrosion-resistant nickel chromium alloy supplied in the hot worked, solution annealed and age hardened condition. The other main challenge with the welding of duplex and super duplex stainless steels is maintaining the balanced austenite:ferrite microstructure.

This super alloy (also known as UNS N07718) contains significant levels of iron, columbium, niobium, and molybdenum, in addition to smaller amounts of aluminum and titanium.
We produce Inconel wire in grades- Inconel 600, Inconel 601, Inconel 625, Inconel 718 and Inconel X-750. Inconel 600 Wire:Inconel 600 is a non-magnetic alloy that is used in the diverse corrosion resistant applications for offering exceptional resistance to chloride based stress corrosion cracking. Inconel® 718 (Alloy 718) Material Data - UNS N07718 UlbrichThe poor age-hardening response of alloy 718 permits annealing and welding without spontaneous hardening during heating and cooling. This alloy has excellent weldability compared to the nickel-base super alloys hardened by Aluminum and ium.

Jul 08, 2013 · Stainless steel grade Nitronic ® 50 can be formed using the same methods applied for other austenitic stainless steels. More power for forming and forging is needed for this alloy. Forging can be done at 1177-1204°C (2150-2200°F). Welding. Welding of stainless steel grade Nitronic ® 50 can be Welding Forum > inconel 718 to stainless 304lFeb 28, 2010 · Trying to get through a weld test that involves joining inconel 718 to stainless steel 304L [TIG]. The test is a butt weld. Have been told to use inconel 718 as a filler rod. Results from first test show penetration in to both parent materials but filler rod has only fused to the inconel and looks as though its just sitting on the s/s. welding inconel 718 - Miller Welding Discussion ForumsJerm, Just weld as if you are welding stainless, with the proper filler ofcourse (718) the puddle will be a little different but not alot as compared to stainless, be sure to use some argon behind the weld, if your going to get your weld x-rayed for a cert besure to file the edges to make sure there clean and scrub the rod with alcohol and scotchbrite and wipe with clean cloth.
