TL;DR: In this article, the optimal selection of process parameters for wire arc additive manufacturing technology, an emerging solution for additive production of metal parts, is based on the evolution of the microstructure and on the mechanical properties of the final samples obtained through the successive deposition weld beads of a ER70S-6 steel.

TL;DR: In this paper, a novel heat source model is proposed based on the actual power distribution between filler and base materials, and an experimental validation is provided by comparing the measured distortions of a test case with the simulated ones, highlighting the accuracy of proposed model.

TL;DR: In this article, a finite element analysis of the thermal behavior of the workpiece is used to schedule the deposition of inter-layer idle times for wire-arc additive manufacturing process.

TL;DR: In this paper, the problem of selecting an optimized strategy for the manufacturing of T-crossing features is addressed in the context of wire and arc additive manufacturing (WAAM), which is an arc-based technology characterized by high productivity, high energy efficiency and low raw material cost.

TL;DR: In this article, an analysis of air jet impingement performances by means of a hybrid numerical-experimental approach is presented, where different samples are manufactured using AWS ER70S-6 as filler material, with different interlayer idle times.
