Automatic Boxed Beam Machine

Automatic Boxed Beam Machine

In general, box beams lend themselves to a clean-lined and more transitional aesthetic than solid beams. If you prefer a rustic antiqued look, consult with your architect, interior designer and custom builder regarding pricing and availability of solid timbers.

Changing from a straight rail to a box tooling takes less than 10 seconds and does not require any additional adjustments.

Baffler Assembling and Welding Machine

This machine is the special equipment to assemble and weld the middle clapboards in Box-beam. It uses the cylinder compacting to determine the position when assembling, and then weld them by spot welding. After oneface welding finished, it turns over the work table for 180 degree by motor to finish another face welding.

Unlike older designs, in which the baffle stack is welded to an external tube, Sig fabricates theirs so that automatically boxed beam machine they have internal skirts that the baffle stack can be pressed into. This allows the baffles to be welded their full circumference to each other, which increases their strength and rigidity. This process also cuts down on the amount of weight that is required to support the baffle stack.

The cooling assembly kit includes a baffle plate with a bore configured to generally bisect an internal volume of the welding apparatus. A fan assembly is positioned in the baffle plate opening to circulate air through both volumes.

The rack assembly 12 is slidably coupled to the base 16 of the housing 14 so that it can be retracted into a closed position as shown in FIG. 2. The locking device (not shown) couples the rack assembly to the base on both sides. Wheels 38, 40 and a handle 42 enable the welding machine to be maneuvered and transported easily to different job sites.

Bottom Plate Assembling and Welding Machine

The bottom plate assembly and welding machine is designed to perform vertical upward fillet welding of the web of a longitudinal member, horizontal fillet welding of a stiffener, and back welding of the inner bottom plating. The welding machine uses a small-sized robot and is configured to be light in weight for easy transporting between blocks. The robotic system utilizes computer numeric control technology to accommodate variations in job-work.

The welding machine is equipped with a rack assembly that slidably extends from and retracts with respect to the base of the welding apparatus. The rack assembly includes two abutting clamping jaws 92 positioned on either side of the central positioning block 91, and an L-shaped mounting plate 93 configured to support the abutting clamping jaws 96. A power device such as an air cylinder is provided to drive the abutting jaws 92 and abutting members 93 to slide towards each other.

The abutting jaws are pressed against the long and short sides of the L frame to maintain proper positioning for subsequent welding operations. Since the abutting jaws and abutting members 93 are moved by the power device, they are less likely to damage the L frame and are able to move with sufficient coordination with other mechanisms in the welding equipment to avoid the build-up of excessive clamping force that could otherwise harm the L frame.

Web Plate Assembling and Welding Machine

A special machine for assembling and welding the bottom plate, web plate and baffle plate of box beam. It combines assembly machine, welding machine and straightening machine into one unit, which improves productivity, reduces cost and saves installation space.

The position fixing machine moves the two wing plates and the web plate to a position where they can be spot welded together. Then, the welded part is conveyed to the welding device and welded by single-wire submerged arc. The weld seam can tolerate gaps of up to 5 mm.

After the welded part is finished, it will be conveyed to the correcting device for cold-working correction. Depending on the design of the welded part, this can include vertical upward fillet welding between a collar plate and a transverse member or horizontal fillet welding between a stiffener and the face of a longitudinal member.

In addition to a standard set of controls, the system includes a touch screen operator interface for easy programming and operation. It features diagnostics indicators, message display and custom graphics including electrical and hydraulic schematics and functional diagrams. It also allows the operator to select a program and display a summary of its progress at each automatically boxed beam machine stage. A variety of additional functions are available for customization and control of the weld process, such as dual-wire welding.

Electro Slag Welding Machine

The electro-slag welding method is an efficient way to join thick pieces of metal together without distortion or spatter buildup. However, it should be performed only by qualified professionals who understand how to handle electricity safely while working with metals. The process uses a lot of electricity to produce the arc and melt the weld material, which can pose a safety hazard if not handled properly. If you are considering using this welding technique for your next metal project, here is what you need to know about the procedure:

During the construction of the San Francisco-Oakland Bay Bridge tower base, ironworkers used the narrow gap improved (NSI) electro-slag welding process to make 20 welds 10 feet tall and up to 100 mm (3.94 in) thick. These single-pass welds included transition butt joints, tees, and splices of girder segments. In addition to welding the welds, gang members had to perform a variety of maintenance tasks including operating the data recorder and monitoring a number of welding parameters, such as slag formation, audible weld characteristics, and cooling shoe movement.

To initiate the arc process, current flows from the welding electrode to the base plate. This produces heat that melts the welding flux, creating a liquid slag pool around the electrode. This is followed by an upward motion of the copper shoe and welding wire feed mechanism that unlits the slag cavity to form a strong weld in one pass. The use of an electric arc power source with flat characteristics is highly recommended for this application as it will keep the current and voltage constant and prevent oscillations in the weld slag pool.
