| description | The invention relates to the technical field of quench cooler preparation, in particular to a U-shaped heat exchange pipe and pipe plate welding process and application thereof. The U-shaped heat exchange pipe and pipe plate welding process comprises the steps of (1) groove machining; (2) groove clearing and inspection; (3) pipe penetrating of a heat exchange pipe according to rows; (4) pairing and priming coat welding; (5) priming coat detecting; (6) cover face layer welding; (7) cover face layer detecting; and (8) pressure-resistant testing. A groove in the welding part of the heat exchangepipe and a pipe plate is changed from an inner groove in an original method to a V-shaped outer groove, and is welded through manual argon arc welding instead of inner hole welding, and thus the manufacturing cost is greatly lowered. Meanwhile, in order to meet the condition that manual argon arc welding replaces inner hole welding, traditional pipe penetrating of the heat exchange pipe accordingto columns is changed to p |
