It was very satisfying. When repairing the tank of stainless steel, the screws of the welded joint were damaged considerably and I was troubled because I could not get in any way. Screws are smoothly entered only by modifying the screws, repairing pipes can cut costs more than expected, and it is now possible to respond to future repairs.
