a welding together

Joseph F. Smith: The same principles that apply to the living apply also to the dead. … And so we are baptized for those that are dead. The living cannot be made perfect without the dead, nor the dead be made perfect without the living. There has got to be a welding together and a joining together of parents and children and children and parents until the whole chain of God's family shall be welded together into one chain, and they shall all become the family of God and His Christ.
