Using Gas Metal Arc Welding (GMAW) with AHSS does present some technical hurdles. AHSS are sensitive to heat inputs of GMAW and can potentially suffer from microstructure changes and reductions in mechanical properties. It's a problem made all the worse in the down-gauged sheet made possible by AHSS strength. In his GDIS presentation, Ford's Elliott outlined some of the company's ongoing work to optimize GMAW process variables and weld-line geometry. For example, he identified a number of variables that can increase fatigue life of a lap-welding joint between a 3.4 mm AHSS (DP 600) and a 3.8 mm mild steel. Among the variables are decreasing wire feed speed and travel speed while increasing torch angle, push angle and the contact-to-work-distance.
A few weeks ago, Ford Motor Co. quietly announced that it was rolling out a new wrinkle to the powerful safety feature called stability control, adding even more lifesaving potential to a technology that has already been very successful.
It won't be too much longer and hardware design, as we used to know it, will be remembered alongside the slide rule and the Karnaugh map. You will need to move beyond those familiar bits and bytes into the new world of software centric design.
People who want to take advantage of solar energy in their homes no longer need to install a bolt-on solar-panel system atop their houses -- they can integrate solar-energy-harvesting shingles directing into an existing or new roof instead.
