Abstract of the Disclosure A method of repairing a wall of chemical process equipment is disclosed which is particularly suitable for repairing a vessel having an outer shell and an inner liner having tantalum as a base constituent wherein the liner has a fault such as a corrosion pit. The fault is repaired by drilling a hole through the fault, liner and shell, the diameter of the hole through the liner being at least as great as the diameter of the fault. A lifting means such as a screw is inserted into the hole to raise the liner away from the shell. The hole through the shell is enlarged, the screw is removed from the liner, and the area between the raised por- tion of the liner and the shell is cleaned. An insert having tantalum as a base constituent is inserted into the hole, the areas on both sides of the insert are evacuated and purged with an inert gas, and the insert is welded to the liner to form a seal therebetween. A second insert preferably having steel as a base constituent is inserted into the enlarged portion of the hole and is welded to the shell to thereby complete the repair of the wall.
