Lasers in Parma

To say that the GM Parma Metal Center is instrumental in the production of assembly and stampings for the OEM would be to make a huge understatement: at the 2.3-million ft2 facility the team processes over 1,000 tons of steel per day. The facility is capable of producing up to 100-million parts per year. Among the vehicles that it supplies stampings and assemblies for are the Chevy Silverado, GMC Sierra, Chevy Tahoe and Suburban, GMC Yukon and Yukon XL, Chevy Colorado, GMC Canyon—which pretty much account for the biggest-selling vehicles in GM’s fleet—and an array of Cadillacs—Escalade, XT5, XT6, CT6—as well as other Chevy, Buick and GMC products.
Although GM shut down the Lordstown Assembly plant in March, in May it announced that it is investing some $700-million in three other Ohio-based plants, DMAX in Moraine to increase production of diesel engines for its new heavy-duty pickups; Toledo Transmission to expand 10-speed truck and SUV transmission manufacture; and at Parma for increasing the output of stampings and assemblies.
They produce parts with both steel and aluminum.
What is notable about the investment in Parma is that it is the only one of the three where a specific technology is noted: laser cell welding technology.
They’re no strangers to laser welding at Parma. Among the subassemblies, for example, that are produced with the process include roof rails, roof headers and center pillars.
The new cells, which will have a common architecture, will be based on six-axis robots for manipulating the welder.
When asked about the advantages of laser welding for the applications, the answer has multiple aspects, including: the ability to perform welding at a distance of up to 1 meter from the parts; fast throughput, with a speed on the order of 0.5 to 1 second per weld; no filler metal required; the ability to weld both coated and uncoated material; and the ability to perform single-side welding, which means that there are not the issues associated with weld gun clearances and closed-out welding conditions.--GSV
Several years back, one of the authors visited a major North American assembly plant engaged in the launch of a new vehicle program. A "ramp-up" schedule was prominently displayed on a bulletin board deep in the heart of the plant. The schedule indicated that the day of the visit was the same day the plant was originally planned to achieve full capacity production of its new product. Yet the plant was actually producing only a few units an hour! The assembly plant's tardiness is certainly not uncommon, but did contribute to our interest in the wide range in vehicle launch performance across major vehicle firms.
In two hours or less, you can create fairly sophisticated animations from your CAD system's solid models so that people who know nothing more than how to use Microsoft Word and PowerPoint on their Windows-based computers can better understand a part or assembly design
