Problems solved by technology

Because the surface of the square steel steps is uneven, and the ladder frame and the square steel steps are mainly welded by climbing welding in the prior art, it is easy to have welding pool accumulation at the welded joint of the ladder frame and the square steel steps. The welding level requirements are relatively high, and the above-mentioned welding method is used to weld the marine ladder, the welding efficiency is low, the welding appearance is not beautiful, and the grinding workload after welding is relatively large

Abstract

The invention provides a welding method for a marine vertical ladder, which is characterized in that it includes the following steps: providing two ladder frames and a plurality of square steel steps, inserting the square steel steps into the two ladder frames evenly at equal intervals; Fix the frame according to the side standing position; carry out pre-welding treatment on the ladder frame and square steel steps; connect the second inner side of the ladder frame with multiple square steel steps and the first outer side of the ladder frame The joints of the steps are welded by staggered welding; the ladder frame to be welded and multiple square steel steps are turned 180°, and the joints between the first inner side of the ladder frame to be welded and multiple square steel steps and the ladder The joints between the second outer surface of the frame and the multiple square steel steps are welded in a staggered welding manner; the welded ladder frame and the multiple square steel steps are inspected.

Description

technical field [0001] The invention relates to the technical field of welding material welding, in particular to a welding method for a marine ladder. Background technique [0002] In shipbuilding enterprises, marine ladders are commonly used vertical passage facilities in ships, and are often used in liquid tanks, empty spaces and other places for staff to enter and exit. In the prior art, the marine vertical ladder includes a ladder frame and square steel steps. When welding the marine vertical ladder, the marine vertical ladder is first laid flat, and then the inner and outer sides of the joint between the ladder frame and the square steel steps are welded. Turn the marine ladder over to obtain the other side of the marine ladder, and weld the inner and outer sides of the other side of the marine ladder. Because the surface of the square steel steps is uneven, and the ladder frame and the square steel steps are mainly welded by climbing welding in the prior art, it is e...
