Abstract

The invention provides a double-ball head bulb flat steel component and a welding method thereof. The double ball head flat bulb assembly consists of two welded double ball head flat steel pieces. The double ball head flat bulb steel includes a ball head and a web. The end face of the ball head is provided with a 25°±5° groove, and the side of the web is provided with There are 30°±5° grooves; two 25°±5° grooves are welded, and two 30°±5° grooves are welded. The welding method of the double-ball head flat bulb assembly includes the following steps: 1) two pieces of double-ball head flat bulb are facing each other; 2) bottom welding; Bottom welding is performed on the two webs; then a second straight gasket is set on the back of the two ball joints to perform bottom welding on the two ball joints; 3) The two webs are filled and covered; 4) On the two A second straight gasket is arranged on the front of the ball head, and bottom welding is performed on the two ball heads; 5) The two ball heads are filled and covered to obtain a double ball head bulb flat steel assembly. The welding method is simple, 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...
