"T" JOINT WELDS for ELECTRON BEAM WELDING

FIGURE 13

The melt-through or blind tee joint shown in Figure 13 is used when a part configuration prevents accessibility to the faying plane.

Examples of this condition are reinforcing rings inside a cylinder, plate-fin heat exchangers, or integral stiffened sheets.

Part and scribe line locations are critical to the success of welding this joint design.

Full penetration "T" joints may be welded from one side using the electron beam welding process as shown in Figure 14.

The beam is introduced to the joint at a slight angle and can produce a "double fillet" effect on thin materials.

For thick sections, welding from both sides, as illustrated in Figure 15, is recommended to achieve full penetration.

"T" joints may be produced having minimal distortion, without the need for elaborate joint preparation, using the electron beam welding process.
