What Is The Process?

Spot Welding – Two separate metals are clamped together and held between the two electrodes. The electrodes touch both pieces of metal and an electrical current with high amps is passed through the electrodes. This seams both of the pieces of metals together with a weld.

There are different types of welding, spot manual and automatic and seem welding, each requires a different level of cooling.

Spot Welding Applications Considerations

  • What is the temperature of the chilled water required?
  • What water pressure do you require at the tools?
  • What is your welder type?
  • What is your welder KVA input?
  • What is the water treatment on process?
  • What is the automatic fill on process?

Why Is Cooling Required For The Spot Welding Process?

The electrodes need cooling via the water lines to insure they do not over heat. If they overheat the weld loses its quality and the probes stick to the work piece.

What Must The Cooling System Include?

Manual By-Pass on chiller circuit; it is likely the water flow could change during operation so it is important the chiller always has its required minimum flow.

Glycol is not advisable as the welding tips sometimes come out and the cooling fluid goes on to the floor.

It is always advisable to use a non-ferrous circuit as water make up will cause corrosion of mild steel.

How To Calculate The Cooling

Use 5% of the KVA input for manual spot welder
Use 7.5% of the KVA input for automatic spot welder
Use 10% of the KVA input for the seam welder
