A double-ball-head flat-steel component and its welding method

Abstract

The invention discloses a double-ball head ball flat steel element and a welding method thereof. The double-ball head ball flat steel element comprises an upper ball head and a lower ball head, wherein the upper ball head and the lower ball head share the same specification and are symmetrically arranged, and fixed blocks are connected with both the outer wall of the bottom of the upper ball head and the outer wall of the top of the lower ball head. The welding method comprises the first step of observing whether the situation of corrosion occurs on the welding faces of the upper ball head, the lower ball head, the fixed blocks and a steel plate or not; the second step of polishing the welding faces of the upper ball head, the lower ball head, the fixed blocks and the steel plate to remove the corrosion according to the corrosion situation if the corrosion occurs. According to the double-ball head ball flat steel element and the welding method thereof, the contact area and welding spots of the steel plate and the ball heads can be increased, the structure of a section bar is more stable, oxide and impurities of the welding face of the section bar are removed, so that the connection of the section bar can be more tight, the desoldering phenomenon is reduced, and the safety coefficient of the section bar is provided.

Description

technical field [0001] The invention relates to the technical field of flat bulb steel components, in particular to a flat bulb steel component with double ball heads and a welding method thereof. Background technique [0002] Bulb flat steel is a medium section mainly used in the field of shipbuilding and bridge building, among which the marine bulb flat is an auxiliary medium section for shipbuilding. With the rapid development of the shipbuilding industry in recent years, the demand for marine bulb flat steel is strong. Generally, the main hull of larger ships and regular ships is mostly made of flat bulb steel for ships, and the flat bulb steel with the same thickness and material as the connected plate is used as the frame. With the development of the market and the needs of the society, the flat bulb steel The types of flat bulbs continue to increase, and some manufacturing industries need to use flat bulbs with double ball heads, but the existing double-ball flat bul...

Generally, the main hull of larger ships and regular ships is mostly made of flat bulb steel for ships, and the flat bulb steel with the same thickness and material as the connected plate is used as the frame. With the development of the market and the needs of the society, the flat bulb steel The types of flat bulbs continue to increase, and some manufacturing industries need to use flat bulbs with double ball heads, but the existing double-ball flat bulbs have fewer welding points, and their firmness is worse than that of flat bulbs, and the flat bulbs are longer when welding. The surface is rusted and oxidized after being left for a long time, and it is easy to desolder after welding, which has potential safety hazards and cannot meet market needs
