Specialized Welding Machines & Contact Fabrication Systems


With over 45 years’ experience in the resistance welding business, Welding & Automation has accumulated a great deal of practical experience related to the process.  Over that time span we have presented seminars on resistance welding to large and small corporations to help them gain insight into the theoretical and the practical aspects of resistance welding.

Oftentimes the resistance welding process is misunderstood which results in misapplication, and in some cases product failure.  It is our goal to pass on a full understanding of resistance welding to help manufacturers develop the skills necessary to use resistance welding to its maximum potential.  Oftentimes resistance welding is treated like an art form when in fact it should be treated as a science with proper training and discipline.  Our seminars can be tailored to specific people, and their interests, or we can present our default format which is geared to the following cross section of people:

  1. Design engineers.
  2. Manufacturing engineers.
  3. Manufacturing technicians, and set up people.

Our presentation requires two days, with each day lasting approximately six hours. Both days are broken into four ninety minute sessions.  Booklets covering the basics of resistance welding will be handed out to all attendees for future application reference.  Total participation and questions are encouraged. We welcome discussions on existing manufacturing problems and sample problems for class review. It is recommended that the class size be limited to 25 people to optimize class participation, and maintain the interest levels of all who attend.

The presentations will include the following:

  • A thorough explanation of the resistance welding process
  • Product design considerations relating to materials, joint design, weld projections, and the electrical characteristics of a welded joint
  • Provide an overview of controls, transformers, and the different machine types used in the resistance welding process.
  • Single phase, three phase, capacitor discharge, and mid frequency control systems are reviewed.
  • Weld schedule development and documentation.
  • Process capability, and weld criteria correlation is handled in depth.
  • An overview of machine set up, tooling considerations, and general machine maintenance is addressed.
