TL;DR: In this paper, the authors present some possibilities of arc control for the gas-metal arc welding process, by using the conventional electrical parameter range and an extended electrical parameters achieved by an auxiliary power electronic circuit.
Abstract: The arc is the technological tool in the arc welding process. Improved welding quality requires precise control of the arc in all different welding phases. This paper presents some possibilities of arc control for the gas-metal-arc welding process, by using the conventional electrical parameter range and an extended electrical parameter range achieved by an auxiliary power electronic circuit. Another way is to use an external magnetic field for controlling the arc.

TL;DR: In this article, the tensile strength and micro-hardness of the Ti-Fe joint were evaluated using optical microscopy, scanning electron microscopy and x-ray diffraction analysis.
Abstract: Electron beam welding experiments of titanium alloy to stainless steel with V, Ni, Cu and Ag filler metals were carried out. The interfacial microstructures of the joints were examined by optical microscopy, scanning electron microscopy, and x-ray diffraction analysis. Mechanical properties of the joints were evaluated according to tensile strength and microhardness. The results showed that all the filler metals were helpful to restrain the Ti-Fe intermetallics formed in the Ti/Fe joint. The welds with different filler metals were all characterized by solid solution and interfacial intermetallics. And the type of solid solution and interfacial intermetallics were depended on the metallurgical reactions between the filler metals and base metals. The interfacial intermetallics were Fe2Ti + Ni3Ti + NiTi2, TiFe, Ti2Ag, and Cu2Ti + CuTi + CuTi2 in the joints welded with Ni, V, Ag, and Cu filler metals, respectively. The tensile strengths of the joints were primarily determined by the hardness of the interfacial intermetallics. The highest tensile strength was obtained in the joint welded with silver filler metal, which is about 310 MPa.
