The 2007 Fabtech International & AWS Welding Show surpassed attendance expectations and set new highs for number of exhibiting companies and net square footage of exhibit space, according to show organizers.
The four-day showcase of metal forming, fabricating, stamping, tube & pipe, and welding equipment attracted nearly 31,000 visitors from more than 75 countries worldwide, a 27% increase compared to the last time the show was in Chicago in 2005. Attendees visited exhibits filling 461,627 square feet of booth space in the North and South Halls of McCormick Place.
This annual event is cosponsored by the American Welding Society (AWS), Fabricators & Manufacturers Association International (FMA) and Society of Manufacturing Engineers (SME) and supported by industry partner the National Association of Manufacturers (NAM).
Fabtech International & AWS Welding Show also offered a line-up of more than 100 conferences, seminars, professional programs, and other technical sessions. Topics covered the best practices, latest trends, and new commercial developments in forming, fabricating, welding, and related technologies.
Next year's Fabtech International & AWS Welding Show will take place October 6-8, 2008 in Las Vegas for the first time. This new location was selected after exhibitors expressed an interest in reaching the large number of metal fabricating technology users located in the Western region of the U.S. More than 700 exhibitors have already reserved close to 90% of the available space for the 2008 event.
Here is a sample of the products on display:
New flatbed laser. Trumpf Inc introduced a new flatbed laser, the TruLaser 5030 that has a newly designed beam guide and cutting head that can process all sheet thicknesses using the same cutting head. The machine automatically changes the laser beam depending on the material to be processed.
Hybrid laser welding system was introduced by ESAB Welding & Cutting Products, Florence SC. The hybrid laser arc welding (HLAW) process is a mechanized laser-welding system utilizing laser only, laser with cold wire fill, or hybrid laser arc welding in a 2D gantry, 3D robotic, or custom mechanized solution with closed-loop weld process control. New this year is a collaboration with Trumpf Laser to include the Trumpf TruDisk laser resonator on the HLx Series. All the components of these systems are available from a single source and are supported and serviced by ESAB.
Hybrid Laser Arc Welding (HLAW) combines the deep weld penetration and low heat input associated with laser welding with the power efficiency and superior gap tolerance of GMAW to create a new welding alternative. The deep penetration and fast weld speeds of laser welding reduce heat infusion into the part and reduce the associated distortion that causes plates to buckle and warp, making fit-up unpredictable and often costly to repair. This deep penetration, however, can limit laser welding's ability to produce acceptable weld fusion in weldments with wide gaps between parts. Adding GMAW in tandem with the laser, with the addition of a relatively modest amount of filler metal, creates a wider weld bead capable of bridging much larger weld gaps, up to four times as wide as conventional laser processes can handle. Adding GMAW to the welding mix also enhances a finished part's metallurgical stability, and with GMAW's slower cooling rates, produces welds with greater strength and less brittleness. This is especially beneficial for higher alloyed steels sensitive to hot cracking.
Multiple operations can be performed with the Pullmatic 720 punching system from Pullmax Inc, Rolling Meadows IL. It punches, forms, bends up to three inches, marks, taps, and cuts. Each tool rotates up to 360°. It also can be equipped with a laser if required, and its automated material handling system permits parts to be fabricated even when the machine is unattended.
