Abstract

Described is a hardware implementation that improves the fabrication methods of sheet-metal products, such as computer base frames, in such a way that spot welding is unnecessary. The method used involves the use of a patented process called "Tog-L-Loc"* that mechanically joins metals with a single press stroke.

Sheet-Metal Fabrication Method to Eliminate Need for Spot-Welding

      Described is a hardware implementation that improves the
fabrication methods of sheet-metal products, such as computer base
frames, in such a way that spot welding is unnecessary.  The method
used involves the use of a patented process called "Tog-L-Loc"* that
mechanically joins metals with a single press stroke.

      In prior art, spot-welding has been used to join sheet-metal
fabricated base frames together.  The materials welded together often
were not joined satisfactorily and during the fabrication often
produced fumes that could be hazardous to health.

      The concept described herein eliminates the need for
spot-welding by using the patented "Tog-L-Loc"* process which joins
materials with a single press stroke.  A joint that is leak proof is
formed from the parent materials without the use of fasteners and the
process does not burn or pierce protective coatings.  The process
produces a strong joint with a round button head that ensures system
mechanical integrity, such as fragility, vibration, electro-magnetic
compliance, and safety requirements.
