Welded Joints in Cold Worked Sheet Metals

Big strength, indispensable for special manufacturing, maintenance for cracked and worn elements, productive, advantageous shapes can be designed.

Just for certain materials, warpage, after-welding process needed, no damping effect, non-destructive control is cost effective.

A point or edge where two or more pieces of metal or plastic are joined together.
