5 Things You Should Know if You Do Flash Welding

In this presentation, WeldComputer Founder Bob Cohen explains how resistance welding operations can increase flash welding performance while reducing energy utilization. You will learn how to: increase the flashing capability of your machine, increase flashing consistency, increase upset consistency, provide proof of flashing and upset consistency of every weld, and reduce energy demand and flicker on the power line. […]

Why Are There Black Spots on My Aluminum Welds? Here’s What You Need to Know.

A manufacturer contacted us recently with a problem:  Their welding performance looked good and their machine performing well. But each aluminum weld created had a dark spot that was noticeable. They were concerned about the impact this cosmetic defect was having on the appearance of their product, and the perception that it could be impacting […]

Is Your Old Resistance Welding Control the Reason For Your Costly Energy Bill?

We all know that your resistance welding control needs to check the boxes for all the core criteria when it comes to your welding operation; ensuring weld consistency, weld quality, and low maintenance are at the top of the list. But sometimes, things that may not seem obvious can show up as hidden (or at […]

The 3 Key Things to Consider Before You Buy or Upgrade Your Resistance Welding Machine to Avoid a Costly Decision

Get more out of your existing resistance welding machine by upgrading your control. If you are in the market for a new resistance welding machine, this article might save you tens of thousands of dollars. Our team collaborates with resistance welding manufacturers to help solve problems of reliability and inconsistent weld performance. Often, the conversation […]

Do I need less KVA for an MFDC transformer than an AC transformer?

For resistance spot welding, resistance projection welding, and resistance seam welding, the RMS current needed to weld a specific material of a specific thickness will be similar for MFDC as for AC. If all things are considered equal, where the only variable is the weld transformer type, the same KVA MFDC or AC transformer is […]

Resistance Weld Machine Spring Constant Impacts Welding Results

Often resistance welding operators report that their setup is exactly the same except that now the welds are different.  They don’t realize that a seemingly irrelevant adjustment to the geometry of the welding setup can change the spring constant of the linkages applying electrode force to the part.  While a change in the spring constant […]
