Abstract
A technique for securing a tube to a flange includes the steps of inserting the end of the tube into an aperture provided on the flange from the first side of the flange such that a portion of the tube extends at least to, and preferably beyond the second side of the flange opposite the first side. A ceramic plug is optionally inserted into the end of the tube to prevent weld spatter and tube burn-through. The tube is then welded to the flange about the circumference of the tube from the second side of the flange, and that portion of the tube which extends beyond the second side of the flange is removed by grinding to produce the finished product.
