We have spent 30 years gaining the knowledge required to develop our own seam welders. We offer both Circumferencial and Longitudinal models, with knurl drives, direct drives, with filtered recirculating drip pans, and special tooling that is compatible with our equipment. We also always endeavor to have a wide selection of used seam welders on hand to refurbish, should the need arise for a more economical solution.
Seam Welders, Circumferencial - A Spot Weld, Inc. Circumferencial Resistance Seam Welder uses our own proprietary seam head design. The head design is at the same time simple, easy to maintain, easily rebuildable, and carries a very high amperage rating for its size. Standard machines are gear & chain driven, with knurlers optional. (Knurlers are for welding coated materials such as galvanized, aluminized, and galvanneal).
Seam Welders, longitudinal - A Spot Weld, Inc. Longitudinal Resistance Seam Welder uses an upper drive wheel with a lower idling wheel. The lower wheel uses a yolk and bushing design, with replaceable inserts to allow repairs to damaged or poorly maintained surfaces. Standard machines are gear & chain driven, with knurlers optional. (Knurlers are for welding coated materials such as galvanized, aluminized, and galvanneal).
Seam Welding, alternative method - Many of the Spot Weld, Inc. standard machines can be modified to include a "Rapid-Fire" option. A specially designed water cooled air cylinder is added that allows a traditional spot welder to achive 60 welds-per-minutee and we have seen up to 100 welds-per-minute with this technique. This is an inexpensive alternative to seam welding, and can be considerably more adaptaptable than traditional seam welding for complex geometry.
