Method for repairing and improving structural integrity of storage tanks
In some implementations of ignition-free welding in at least one fastener is attached to a container that resides within a hazardous environment. The fasteners are then used to secure a fill zone to the container. The chamber then receives a sealing material for the purpose of sealing a leak without having to remove the hazardous material.
