The influence of the arc plasma on the weld pool in simulations of arc welding
Results from a computational model of arc welding, in which the arc plasma, workpiece and electrode are treated self-consistently, are presented. It is demonstrated through three examples (the effect of shielding gas composition, metal vapour and electrode shape on the weld pool) that reliable prediction of weld pool depth and geometry requires that the arc plasma is included in the computation...
متن کاملInfluence of Gliding Arc Cold Plasma Based on Argon, Helium and Compact Air on Bactria Around the Wound: Experimental Investigation
Background: Today, the use of cold plasma and its applications have taken into consideration. The plasma is a mixture of active oxygen and negative ions. This compound has a practical effect on the elimination of all types of bacteria and viruses. The cold plasma feature is essential and very useful in disinfecting processes. In this investigation, we plan to study the effect of gliding arc pla...
متن کاملOn the decompression melting structure at volcanic arcs and back-arc spreading centers
[1] Mantle dynamics can strongly affect melting processes beneath spreading centers and volcanic arcs. A 2-D numerical model of the Tonga subduction zone, with the slab viscously coupled to the mantle beneath the brittleductile transition but faulted above, shows that induced corner flow may cause asymmetric melting at the Lau backarc spreading center, 400 km away. The down-going slab also entr...
متن کامل1 Arc Plasma Torch Modeling
Arc plasma torches are the primary components of various industrial thermal plasma processes involving plasma spraying, metal cutting and welding, thermal plasma CVD, metal melting and remelting, waste treatment and gas production. They are relatively simple devices whose operation implies intricate thermal, chemical, electrical, and fluid dynamics phenomena. Modeling may be used as a means to ...
متن کاملNanostructured Bi2Te3 Prepared by a Straightforward Arc-Melting Method
Thermoelectric materials constitute an alternative source of sustainable energy, harvested from waste heat. Bi2Te3 is the most utilized thermoelectric alloy. We show that it can be readily prepared in nanostructured form by arc-melting synthesis, yielding mechanically robust pellets of highly oriented polycrystals. This material has been characterized by neutron powder diffraction (NPD), scanni...
