Title:
WELDING METHOD OF COOLING PIPE
Document Type and Number:
Japanese Patent JPS5776812
Kind Code:
A
Abstract:
PURPOSE: To improve the reliability for strength of the titled material by providing a spilling groove of arc-shape at the corner of arc-shaped or non-arc-shaped bottom of groove of the body to which the cooling pipe is fitted for burying a cooling pipe thereby decreasing the strain concentration at the junction.
CONSTITUTION: A groove 2 with arc-shaped bottom 2a is made on a body 1 to which cooling pipes 3 with arc-shaped bottom similar to the bottom of the groove is fitted. The body and the pipes are bonded with adhesives of different materials such as solder thereby preventing, when the body sustains a load, a large local strain and improving the reliability for strength.
