Abstract

The invention discloses a double-bulb flat-bulb steel component and a welding method thereof. The double-bulb flat-bulb steel component comprises two pieces of double-bulb flat-bulb steel connected in a welding mode, the double-bulb flat-bulb steel comprises bulbs and a web, a 20 to 30 degrees groove is formed in the head face of each bulb, and a 25 to 35 degrees groove is formed in the lateral surface of each web; the two 20 to 30 degrees grooves are welded, and the two 25 to 35 degrees grooves are welded. The welding method for the double-bulb flat-bulb steel component includes steps that 1) enabling the two pieces of double-bulb flat-bulb steel to face to each other; 2) performing backing weld, to be specific, arranging first straight liners at the backs of two webs, and carrying out backing weld on the two webs; arranging second straight liners at the backs of the two bulbs, and carrying out backing weld on the two bulbs; 3) filling the two webs and facing; 4) arranging second straight liners at the fronts of the two bulbs, and carrying out backing weld on the two bulbs; 5) filling the two bulbs and facing to obtain the double-bulb flat-bulb steel component. The welding method is easy to perform, low in cost and high in welding quality.

Description

technical field [0001] The invention relates to a double ball head flat steel assembly, in particular to a double ball head flat steel assembly and a welding method thereof. Background technique [0002] Bulb flat steel is a special type of steel, which is composed of a flat web and a spherical ball head, and is an asymmetrical steel. 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 marine bulb flat steel, and the bulb flat steel with the same thickness and material as the connected plate is used as the frame. [0003] At present, when welding two flat bulbs, in order to improve welding efficiency and welding quality, a special flat bulb liner is re...
