Spot welding allows for two thin sheets of metal to be welded together precisely in a short amount of time. It’s a popular form of welding because the heat produced doesn’t affect the rest of the metal sheet.
Spot welders work by clamping two sheets of metal and passing an electric current through two electrodes to the spot that requires welding. The spot welding machines can be adjusted to deliver different current amplitudes, which allow it to be used on metal of different types and thickness.
Why do we need spot welders?
Spot welders are used often with sheet metal due to its ease of use and benefits that come with using it. Lower heat levels given off compared to other methods of welding and a much shorter welding time make it a quite attractive form of welding.
Examples of uses are:
- Metal buckets
- Consumable parts & automotive industry- Where process can be completely automated in form of welding robots.
