Tailored Blank applications have become more and more important for the advanced light weight and cost effective steel automobile body. During the last decade, the production of Tailored Blanks with a straight weldline has been constantly increasing because their technical and economical advantages are well accepted by automobile manufacturers /1, 2, 3, 4/. But, now the body engineers prefer to have an even more flexible product with specific weldline design, according to the engineering design needs. Thyssen Krupp Stahl AG reacted quickly on this demand and now offers the new product called, Thyssen Engineered Blanks (TEB®s), which meets almost all the needs for the design of components concerning weld-line geometry and weld-line positioning. With our new production line, both single and multiple steel sheets can now be joined together with linear weld-lines, angled weld-lines and curved laser beam weld-lines, Figure 1.

Tactical Air Command trains its crews in progressive phases. This approach not only saves money, but also increases combat capability. The first phase, Lead-In Training, uses the AT-38 to teach young aircrews the basic skills needed to fly today's modern fighter aircraft. During the next phase (Initial Qualification), aircrews transfer the basic skills learned during Lead-In Training to front-line combat aircraft. The Mission Qualification phase adapts fighter skills to specific unit missions. Following Mission Qualification training, aircrews are certified ready to perform their unit's combat mission, but training is not complete. They continue to learn now tactics/skills and improve those learned previously in the Continuation Training phase. Thus, training in TAC is a continuous process, one that steps progressively from the basics of fighter aviation to the most advanced skills needed to defeat any enemy.
