ウィズソル Company Profile

We provide reliable technology to assess product quality and equipment integrity.

Withsol Co., Ltd. has been operating since its establishment in 1961 as a group of non-destructive testing experts, expanding throughout Japan and taking pride in being a company that contributes to the quality assurance of top-tier Japanese industrial products, which are recognized as world-class. We are dedicated to honing our non-destructive testing techniques day and night in manufacturing sites. In addition, our mission is to provide non-destructive testing technology as part of the maintenance of equipment, piping, and machinery in currently operating oil-related and power generation plants, contributing to the maintenance and management of safe and secure plants. Particularly in the technology of "continuous plate thickness measurement" for crude oil and fuel tanks, we own numerous UDT and UDP devices that have received performance approval from the Hazardous Materials Safety Association (KHGK), and we conduct inspections of tank bottom plates, side plates, and roof plates across the country, which we take pride in receiving high evaluations for. Moving forward, we will continue to develop "special inspection" equipment that can adapt to the progress of the times and engage in further research and development to introduce new non-destructive testing methods to the world. Under our corporate motto of "Trust, Effort, Safety," we will continue our unwavering efforts to provide reliable and reassuring inspections.
