situation
A transformer manufacturer was looking for a solution to seal weld porosities as it led to the seeping out of the transformer oil and contamination of the soil. Porosity leaks also resulted in off-line repairs which resulted in increased repair costs and reduced production output.

Conventional methods and drawbacks
Welding over leaking weld beads did not stop the leak and needed high labor cost to drain, clean, grind and weld over the identified porosity leaks.

loctite solution
LOCTITE 290 is applied to the porosity with a brush and shows results within minutes.
