Embodiment Construction
[0022] Such as Figure 1-3 Described, is a kind of seam welding method, comprises the following steps:
[0023] Step 1: Clean the inner bottom plate, raised ribs, watertight bulkhead, watertight patch plate and connection plate, polish the surface of inner bottom plate 1, rib plate 2, watertight bulkhead 3, watertight patch plate 4 and connection plate 5, and remove inner The burrs, rust, dust and peeling on the bottom plate 1, raised ribs 2, watertight bulkhead 3, watertight patch 4 and connecting plate 5 are reserved for use;
[0024] Step 2: Weld the convex ribs and the inner bottom plate, lay the inner bottom plate 1 flatly, draw a plurality of spaced longitudinal scale lines on the upper surface of the inner bottom plate 1 according to the design size, and then place each convex rib 2 along the corresponding longitudinal Place the scale line, use electric welding to fully weld the joint edge of the convex rib plate 2 and the inner bottom plate 1, ensure that there is no ...

The invention relates to a seam welding method and a weld seam inspection method. The welding method comprises the steps that step1, an inner bottom plate, convex rib plates, a watertight cabin wall,watertight repair plates and connection plates are cleaned; step2, the convex rib plates and the inner bottom plate are welded; step3, the connection plates and the watertight cabin wall are welded; step4, a horizontal semi-finished product and a vertical semi-finished product are welded; and step5, the watertight repair plates are welded. The welding method is clear in welding orderliness and scientific and rigorous, occurrence of welding missing is avoided, and meanwhile, later-period weld seam inspection is facilitated. The inspection method comprises the steps of step1, initial inspection;step2, reinspection; and step3, acceptance inspection. The inspection method is scientific and rigorous, by means of mutual cooperation of the initial inspection and the reinspection, a special situation (such as welding slag blocks an inner flow passage or an outer flow passage to form a segment of closed space) of the inner flow passage and the outer flow passage which cannot be inspected out by the initial inspection is effectively inspected, so that the problem of double-flow-passage inspection is solved.
Description
technical field [0001] The invention relates to the technical field of ship welding, in particular to a gap welding method and a weld seam inspection method. Background technique [0002] The existing Chinese patent database discloses a patent titled a vacuum cover for the overall watertightness detection of T-shaped watertight patch panels in shipbuilding. The patent application number is 201410831592.1, the application date is 20141229, and the application publication number is CN104568328A The publication date of the application is 20150429. The device includes a left cover body and a right cover body with the same structure and mutual symmetry. After the left cover body and the right cover body are matched, a T-shaped watertight patch is wrapped in a vacuum cover. A suction port and a pressure gauge are arranged on the cover body. Its disadvantage is that the device can quickly and effectively check whether the weld is welded, but it does not provide a testing method fo...
