8 7 ARGWELD® Trailing Shields Fast Payback■ The use of a trailing shield of some kind for titanium weldingis almost mandatory, for the applications where the productcannot be placed inside a Welding Enclosure■ When welding smaller titanium components, that could beplaced in a Welding Chamber of some kind, Trailing Shieldsmight be dramatically more cost effective thanthe use of a Welding Chamber■ 2 Welds achieves payback
