Interior weld and improved sling
View Patent ↗An interior weld for furniture having a tubular member is disclosed. The weld has a first tubular member and a second tubular member. The first tubular member is adapted to receive the tubular second member. An edge of the tubular second member contacts an inner surface of the first tubular member. A weld is formed on the inner surface of the first tubular member at the contact point where the second tubular member contacts the first tubular member. There is a weld at that contact point which immovably attaches the second member to the first member.
