Often I’m asked by a customer to produce a part made of two dissimilar materials. This is no problem for our skilled staff at V and F Sheet Metal, it just calls for the technique of spot welding. The process whereby two pieces of sheet metal are joined together using spot welds made at regular intervals on overlapping sheets of metal.
We have four spot welding machines in our factory in Fareham, Hampshire set up as individual spot welding bays. We feel it is important to have more than one machine as this gives us the ability to offer our customers a high degree of flexibility and ensures that your “job” is not held up waiting in a queue. Many customers require a quick turn around time and in some cases the moment from order confirmation to delivery is surprisingly short. As the saying goes time is money!

One of the photos shows a close up of the welding electrodes showing copper tips in brass holders. During the welding process the top electrode moves up and down and the bottom one remains stationary. Using these electrodes, the welding current is concentrated into a small “spot”, thus forcing a large current through the spot and melting the metal to form the weld.

In this case the completed part was a mild steel bracket with a zinc plated and colour passivated steel clip attached. The clip was free issued to us by the customer. If you are interested in this particular technique and would like to learn more about the process in detail, then please take a look at the information on Spot Welding sheet metal under our plant list. There’s even a short clip of spot welding in action in our factory!
