Abstract
Silicone resin coatings prepared by the sol-gel method were applied on welding electrodes to protect them against water absorption during st orage or transportation. The performance of the electrodes was tested by measuring the free and total water content of the weld. The total w ater content of the coated electrode was just slightly above the permi tted level (0.2%) due to the organic part of the silicone resins that decomposes during welding liberating a very small quantity of water.
