Description

Light double-wire electrogas welding machine for thick plate for ship
Technical Field
The utility model relates to a double-wire electrogas welding machine, in particular to a light double-wire electrogas welding machine for a thick plate for a ship.
Background
The gas-electric vertical welding is a gas-metal arc welding method developed from common gas metal arc welding and electroslag welding, and is generally used for welding materials such as low-carbon steel and medium-carbon steel. The advantages are that: high productivity and low cost. The main difference with narrow gap welding is that the weld is formed in one pass, rather than in multiple passes of multi-layer welding.
The energy density of the electro-gas welding is higher and more concentrated than that of the electro-slag welding, and the welding technology is basically the same. It uses a water-cooled slide block similar to electroslag welding to block molten metal and make it be forcedly formed so as to implement vertical position welding. Usually with the addition of a single gas (e.g. CO)2) Or a mixed gas (e.g. Ar + CO)2) As a protective gas.
In terms of welding arc and droplet transfer, electrogas welding is similar to ordinary gas metal arc welding (e.g. CO)2Welding, MAG welding), which is similar to electroslag welding in terms of weld formation and mechanical systems. The main difference between electrogas welding and electroslag welding is that the heat of the molten metal is the arc heat rather than the resistance heat of the slag.
The electrogas welding is usually used for welding materials such as thick low-carbon steel, medium-carbon steel and the like, and can also be used for welding austenitic stainless steel and other metal alloys. The thickness of the plate is most suitable to be 12-80 mm. If it exceeds 80mm, it is difficult to obtain a sufficiently good protective effect, resulting in generation of pores in the weld, uneven penetration and lack of penetration. The length of the weld joint is generally not limited, single layer welding being the most common welding method, but multilayer welding may also be used.
However, with the continuous development of industry, the vertical welding requirement for the marine thick plate is gradually increased, and the welding requirement for the marine thick plate cannot be met by ordinary electrogas vertical welding.
