Specializing in Defense Welding Services
At Lynn Welding, we specialize in defense welding services for the defense and military industry. Military spec welding is a United States military welding standard that is used as a basis for quality assurance. This assures the optimum quality of the weld and validates the capability and repeatability of a resistance welding machine used where weld quality is vital in the manufacturing of critical parts, as in the defense and military industries.
Designing and fabricating components for the defense industry is a high-risk endeavor, and our clients trust that we will meet their needs with customized solutions all while keeping costs to a minimum and keeping the highest quality standards. We understand the rigorous standards and deadlines that must be met in the defense welding industry and we strive to meet and exceed these for every project!
