Stainless steel gutter installation
1. The installation conditions of stainless steel gutter and the requirements for the downhole opening are all the same as the steel gutter.
2. Stainless steel gutter welding adopts argon arc welding. The electrode is made of stainless steel wire with the same material as the gutter, and the diameter is the same as the thickness of the plate. 1mm is often used. Before the formal welding, the welder should be organized to carry out the test welding, and the batch welding can be started after the qualification is qualified. At the same time, the special person should be designated as far as possible. At the same time, a auxiliary work coordination operation is arranged to improve the benefit of the main production. After the water inlet is welded, the area should also be properly damaged to facilitate drainage. Contamination of stainless steel electrodes must be removed before contamination can be used.
3, as the stainless steel trench is formed by folding edge processing, it is inevitable that there is a phenomenon of dimensional deviation. So the gap should be checked in an all-round way before it is shipped, as far as possible to minimize the gap between the joints. The spot welding is fixed before welding, and the welding is followed by the bottom of the congenital ditch. Then weld the side of the gutter. If conditions permit, the test row can be carried out, numbered according to the test row after hoisting, in order to greatly reduce the welding workload and ensure the quality of the project. If the gap is too large, the welding wire can not be fully welded. The stitching can be made with the leftover material. It is necessary to pay attention to the necessary circumference welding. At the same time, the weld seam of the edge angle is full and no leakage welding.
