FAST, FLEXIBLE LASER MARKS PRESSURE
TRANSDUCERS (474 KB)
Viatran Corporation discovers the ease and benefits
of using a Nd:YAG laser to mark text and graphics
directly onto their parts. The company's challenge,
marking on the circumference of a variety of stainless
steels (soft materials like 316, 304 and Hastalloy,
and hard stainless steels like 17-4, 15-5 and Inconel)
was met by the programmable laser systems from Rofin-Baasel,
formerly A-B Lasers.
