PECo’s welding engineers will help you determine the best welding process for your material, assembly strength, and specification needs. Your success is our success.

To determine if Capacitor Discharge welding will work effectively for your components, our welding specialists will work closely with you through the following steps:

Step 1: The process starts with a review of your parts drawings. As a result of this review, PECo’s welding specialists will determine if the parts are weldable using Capacitor Discharge Welding or if some other joining process may better meet your needs. If Capacitor Discharge welding is appropriate, our engineers will then review your parts design in more detail to determine if the current design is suitable for the weld you desire and if not, will aide your team in making minor weld preparation changes as appropriate. The results of the Step 1 review will be provided to you for your analysis and evaluation.

Step 2: Once the initial analysis and design changes are made, PECo’s welding engineers will work with you to verify process parameters. Sample parts to be used in weld tests are provided by you or at your request, PECo will manufacture them. PECo will use Capacitor Discharge Welding to join the sample parts and then analyze the weld integrity. The joined parts and weld report will then be returned to you for your evaluation and analysis.

Step 3: At this point the use of Capacitor Discharge Welding as an appropriate joining process for your parts has been proven and the focus shifts to optimizing the process.

Using basic Design of Experiments, PECo will optimize the weld process to best meet your needs in terms of weld strength, cleanliness, fatigue strength, etc. Samples will then be returned to you for your evaluation and testing.

Step 4: Production intent tooling is designed and procured and PECo welds your parts in a production-type manner. Several hundred parts are produced in this step for final evaluation of the consistency of the weld and process. This supports your Production Part Approval Process (PPAP).

Step 5: PECo works with you to develop the production plan, schedule, shipping requirements, etc.

Step 6: PECO begins production welding your parts!

PECo will support your APQP process as well as your PPAP evaluation criteria.
