2025 Top 10 Seam Welding Suppliers in China

Introduction to Seam Welding

Seam welding is a resistance welding process in which overlapping sheets are joined by a series of individual spot welds made in rapid succession. It is commonly used to create continuous, leak - tight joints in various industries such as automotive, aerospace, and the manufacturing of containers. The process involves passing the workpieces between rotating electrodes, which apply pressure and an electric current to form the weld seam. Seam welding offers advantages like high productivity, good joint strength, and the ability to produce aesthetically pleasing welds.
