General Electric is one of the leading patent filers among aerospace and defence companies in blade alloy welding. The company is heavily invested in the development and manufacture of aircraft engines through its GE Aviation business unit, and through CFM International, a joint venture with Safran. The firm holds patents regarding fusion welding for use in aircraft airframes. Other leading patent filers in the aerospace and defence industry include leading engine manufacturers Rolls-Royce and Safran.

In terms of application diversity, Raytheon Technologies holds the most widely applicable patents in blade alloy welding. The company is also involved in engine production through its subsidiaries, Pratt & Whitney and Collins Aerospace. Safran and General Electric took the second and third positions, respectively. By geographic reach, Mitsubishi Heavy Industries leads the way, followed by General Electric and Safran.

Blade alloy welding can offer engine manufacturers an avenue to improve the performance of their products. For example, techniques such as linear friction welding (LFW), which is established in the industry, allow manufacturers to reduce manufacture time and costs, while not compromising on performance.
