Abstract
A method is provided for attaching together a larger tube and a smaller tube in a T-shaped intersecting joint. A hole is formed in the larger tube with a flange surrounding the hole. A circumferential extending flange is formed on the outside of the smaller tube. Adhesive is placed on either the outside of the smaller tube or the inside of the flange of the larger tube. The smaller tube is inserted into the hole in the larger tube so that the adhesive is interposed between the inside of the flange of the larger tube and the outside of the smaller tube and the flange on the outside of the smaller tube comes into electrical conducting contact with the flange of the larger tube. Electrical current is applied to flow between the large tube and the small tube so that electrical resistance heating is obtained to cure the adhesive.
