Steel box column production process is more, here mainly introduces the welding process of steel box column production key processes.
Steel box column in the inner cavity need to add a partition, some of these partitions are due to the beam-column connection, the need to strengthen the design, but also the manufacturing process required to add. When the bulkhead is welded with 4 wall plates, the full penetration weld of the bulkhead and liner should be used, and when the bulkhead is connected with the wall plates on both sides, manual C02 gas shielded welding can be used, and the connection of the upper and lower two wall plates (cover plate) is made by the medium welding technology electroslag welding. Bulkhead CO: gas shielded welding requires bulkhead open K-shaped bevel, when the distance between the two bulkheads is less than 200 mm, the weld channel between the bulkheads is not 40 to facilitate welding can also be used on one side of the V-shaped bevel, the back of the pad, K-shaped bevel and V-shaped bevel must ensure that the penetration of the weld, the welding parameters are shown in Table 2. Bulkhead Electroslag Welding Welding Welding Path is also a full-penetration, Electroslag Welding on the top, the bottom of the hole required to weld the position of the seam in the middle of the flux, the molten nozzle requirements Drying temperature of 200 ~ 250 ℃, the wire out of the nozzle about 20 mm, the same partition on both sides of the electroslag welding should be applied at the same time to avoid deformation of the component welding.

Box beam welding Production Line
Applications
Gantry double-gun electroslag welding machine is a special complete set of welding equipment for box girder spacer welding, and it is an important part of the box girder automatic welding production line,
Functional features
1, the special machine adopts the gantry mobile structure, and the gantry adopts the double-motor drive, which makes the walking stable and reliable.
2, equipped with two sets of swing mechanism, respectively, to control the swing of the two welding guns, swing amplitude and frequency can be adjusted according to the requirements of a certain range, can be rectangular cross-section of the welded hole swing welding.
3. The welding current and voltage are adjusted separately, and the welding torch is automatically lifted with the rise of the slag pool liquid level.
4. The welding power supply adopts 600KH type welding power supply produced by Tangshan Panasonic, which has stable and reliable performance.
