Study of the Spot Welding of Titanium and its Alloys

Abstract

In this investigation, were studied on the following items to establish a proper spot welding procedure of titanium and its alloys.
1). Selection of foundamental spot welding conditions for titanium and α+β titanium alloys.
2). High temperature qualities of the spot welds of these materials.
Consequently, found that titanium and 2%Al-2%Mn-Ti alloy have good properties in as welded, therefore, these can be said to have good spot weldability. And if a proper heat treatment after welding is performed (for instance, water cooling after heated in 600 to 700°C, or the post heat current pass into welds after spot welding, immediately), even 8% Mn-Ti and 4%Al-4%Mn-Ti alloys will be useful in some purpose for use.
