Resistance Welding Services

D&H Industries is an ISO 9001:2015 certified full-service weld shop specializing in resistance welding aluminum, carbon steel, and stainless steel components and finished products. Our turn-key manufacturing comprises sheet metal fabrication, precision stamping, assembly, and electric spot welding services. The resistance welding process has a very narrow heat-affected zone that minimizes distortion compared to traditional welding methods, e.g., MIG and TIG welding, and protects the molecular structure of the metal components. Our welding capabilities include MIG welding, laser welding, and arc welding.

Resistance welding applies the pressure of copper alloy electrodes against metal components while passing an electrical current through them. The resistance welding machine generates heat to a melting point, joining metal components at the weld area called a weld nugget. Metals possess specific thermal and electrical conductivity characteristics requiring different welding electrode forces and times. The high-quality bond between sheet material does not need fluxes, or filler materials, which makes it a cost-effective process for prototype and high production runs. We conduct periodic destructive testing to ensure the validity of our welds. Numerous forms of resistance welding exist, including spot, butt, projection, and seam welding.
