Fast Payback
■ The use of a trailing shield of some kind for titanium welding
is almost mandatory, for the applications where the product
cannot be placed inside a Welding Enclosure
■ When welding smaller titanium components, that could be
placed in a Welding Chamber of some kind, Trailing Shields
might be dramatically more cost effective than
the use of a Welding Chamber
■ 2 Welds achieves payback
