Spot Welding

What Is The Process?

  1. 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.
  2. There are different types of welding, spot manual and automatic and seem welding, each requires a different level of cooling.

Why Is Cooling Required?

  1. 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.

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

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.
