About Us

Founded in the year 2000 by the visionary Mikio Kusano, Weldparts has established itself as a cornerstone in the resistance welding industry. Situated just north of Cincinnati, OH, our journey began with a singular mission: to cater to the diverse needs of the welding community through unparalleled quality and innovation. Mikio Kusano, with his profound expertise and dedication, steered Weldparts to new heights before gracefully retiring from his active role.

Today, Weldparts is proudly owned and operated by Christina Colquhoun, Alan Colquhoun, and Robert Barenz. Together, they continue the legacy of excellence and commitment to customer satisfaction that has been the hallmark of Weldparts since its inception. Our team is passionate about welding and stands ready to support our customers with both knowledge and quality products.

At Weldparts, we understand the unique challenges and requirements of the welding industry. That's why we offer an extensive range of products to accommodate both American and Asian size electrodes, ensuring that our customers can find exactly what they need, regardless of their project scope or geographical location.

Our commitment is to offer solutions that are as versatile and dynamic as our clients' projects.

Customization is at the core of what we do. We believe that every welding challenge has a unique solution, and our team is dedicated to crafting products that meet your specific requirements. No matter the shapes and sizes you need, Weldparts is equipped to deliver precision and excellence.
