3. Welas - release your visions
Welas focuses on fine mechanical laser working. We
cooperate with several fields of industry utilizing the
opportunities of Nd:YAG lasers and our own techno-
logical know-how. We already have many years’ ex-
perience from e.g. medical and instrument industries,
where an extremely precise machining is required.
Our flexible line of action enables to make unique
work pieces, proto series as well as production se-
ries. The cooperation may extend even to contract
manufacturing. A complete delivery may also include
assembly work as well as exacting machining, heat
treatment and surface finishing obtained through
our network.
