According to the specification of the design of concrete structure (GB 50010-2002), the concrete plate shall bwelding connection, the cold pressure connection and the screw connection. In addition to the individual cases (such as no-fire), the welding connection should be used to ensure quality, increase efficiency and save steel. There are two kinds of reinforcement welding and welding. Compression welding including flash butt welding, resistance spot welding and pressure welding. Melt welding includes electric arc welding and electroslag pressure welding. In addition, the welding of the steel bar and the pre-buried t-connector shall be covered by submerged arc pressure welding.
Arc welding system using arc welding machine produce high temperature between the electrode and welding arc (between the electrode and weldment in the air medium strong permanent phenomenon of electricity discharge is called arc), within the scope of the welding electrode and arc burn pieces of metal melt, molten metal solidification, the formation of weld or welded joint. Arc welding application range is wide, such as extension of steel bar, steel skeleton of reinforced with steel plate welding, welding, assembly structure joint welding and other welding steel structure, etc.
The length of a steel reinforcement is usually referred to as the length of the joint and the length of the welding
