Eddy current testing, also referred to as eddy current inspection, is a non-destructive testing technique which employs electromagnetism to observe surface-breaking and sub-surface defects present in the substances. The major areas where the eddy current testing method is utilized involve material identification & heat treatment condition, crack & corrosion detection, and non-conductive coating thickness measurement. As we already mentioned, the eddy current testing technique is a non-destructive testing method. Hence it is applied to various industries. This specific non-destructive testing is carried out in many industry sectors encompassing aerospace, oil & gas, transport, healthcare, and power generation. Therefore, eddy current testing is utilized in various ways within these business sectors. It can be embarked on at the time of production, post-production, during service, and repair as well. Here are the best 7 Eddy Current Testing Companies you might not know! We have curated a list of companies to help you know better about the eddy current industry. 1) Ether NDE Limited In 2019, Ether NDE Limited completed its tenth anniversary.

Takeshi Yamashita, the organization's founder, set up the company by taking the financial assistance of his previous employer, with a great vision of accomplishing domestic manufacturing of microscopes. Yamashita took a step forward and motivated his engineers by stating that sheer imitations of imported commodities would not be adequate and that it would become crucial to develop something genuinely original. After six months of establishing the company, in June 1920, the dream of creating a domestic microscope was made into reality with the inception of Asahi, the first microscope fabricated by Takachiho.On April 4, 2022, Olympus Corporation said in a statement about separating its Scientific Solutions business from a completely owned subsidiary named "Evident Corporation." Pursuing the divestiture of its imaging business this step determines the long-term strategy of a company to establish its position as a major company in the MedTech industry. The split was first announced in the month of June 2021. Therefore, as a brand new established subsidiary, Evident, whose headquarters are in Japan, proceeds to work independently under Olympus. Olympus's Scientific Solutions business includes the Olympus Industrial and Life Science industries. The new name of the company epitomizes their loyalty & commitment to delivering high-end products and technical knowledge, enabling the consumers to learn new things and discover new verification in their sections of expertise. The industrial solutions of Evident cover a wide area from microscopes and video scopes to non-destructive testing equipment & X-ray analyzers for the purpose of manufacturing, maintenance, environmental applications, and much more. Supported by state-of-the-art technologies, Evident products are broadly utilized for inspection, quality control, measurement, etc.3) Etegent Technologies Etegent Technologies was established to integrate state-of-the-art university research into the products & services for the defence and aerospace industries.
