The present application is generally directed to systems and methods for control and management of lighting components connected in a network. A user specified rule is executed to control lighting effects in a lighting network which comprises an interface module in communication with one or more lighting control modules. The interface module may receive a rule for controlling a lighting network. The rule may comprise a user identified input and a user specified lighting effect to occur responsive to the user identified input. The interface module detects receipt of the user identified input and executes the rule to trigger the user specified lighting effect via the one or more lighting control modules.

The invention relates generally to welding and, more specifically, to welding wires for arc welding, such as Gas Metal Arc Welding (GMAW) or Flux Core Arc Welding (FCAW). In one embodiment, a tubular welding wire includes a sheath and a core. Further, the core includes a carbon source and an agglomerate having a Group I or Group II compound, silicon dioxide, and titanium dioxide. Additionally, the carbon source and the agglomerate together comprise less than 10% of the core by weight.

A nitrogen gas tank, a rotary pump and a mechanical booster pump are connected to a bonding vessel that constitutes a bonding apparatus for carrying out diffusion bonding, the apparatus further comprising a pressure sensor. A nitrogen gas atmosphere is formed inside the bonding vessel, and under control operations of a control circuit, a nitrogen introduction rate is controlled so that a pressure is substantially fixed at a predetermined pressure between 3-10 5 Pa. At such a state, under the action of a rod of a hydraulic cylinder, a second electrode is brought into proximity with a first electrode, so that ultimately, a first object to be bonded and a second object to be bonded on the first electrode are pressed. Further, current is applied through the first electrode and the second electrode with respect to the first object to be bonded and the second object to be bonded.

The invention relates to a shielding gas arc welding method for non-ferrous materials, in particular aluminium materials and aluminium alloys, for example AlSi, which method comprises the continuous supply, during welding operation, of a shielding gas containing argon and/or helium to the weld spot (welding point) adjacent to the electrode. According to the invention, a shielding gas is proposed which in addition to argon and/or helium comprises a carbon dioxide fraction or an oxygen fraction or a fraction of a mixture of these gases of from 0.01 to 0.7 % by volume, preferably from 0.01 to 0.1 % by volume (from 100 to 7000 or 1000 ppm, respectively).

Process for making heterogeneous joints under shielding gas In joining heterogeneous materials that differ in their melting points, a shielding gas mixture with active gas content is utilized. In particular, the shielding gas mixture contains helium and active gasses in the vpm range (0.005 to 0.5% by volume). These shielding gases to lead to the production of high quality joints when joining aluminum and steel.

The protective gas, for protective gas arc welding to form joints between materials of different types and melting points, is a mixture with an active gas component. The gas mixture is especially of helium and active gases at 0.005-0.5 vol.%. The gas mixture contains oxygen (O2), carbon dioxide (CO2), nitrogen oxide (NO), dinitrogen oxide (N2O) or nitrogen (N2), argon and/or helium.

Method for joining dissimilar materials in shielding gas

The invention relates to MSG-soldering (metal shielding gas-soldering) of metallic materials with use of soldering and an electric arc with consumable electrode or non-consumable electrode, whereby a shielding gas that essentially consists of inert gas is used. According to the invention, the shielding gas contains at least one active gas component in addition to the inert gas. As active gases, oxygen and/or carbon dioxide can be used. The proportion of active gas in the shielding gas is preferably in the range of 0.01 to 0.5% by volume.

Process for MSG-soldering and use of a shielding gas

The invention relates to shielding-gas arc welding methods making use of the melting (burning-off) electrode and also the non-melting electrode, which involve, during welding operations, continuously supplying the weld spot (welding point) adjacent to the electrode with a stream of shielding gas, the shielding gas being composed for a major part of argon and/or helium. Such welding methods are known in many versions, and quite generally they enable the most diverse materials (ferrous and non-ferrous materials) to be welded together satisfactorily. In a number of practical cases, e.g. with respect to aluminium welding, however, it is possible for welding to proceed in a non-optimal manner, not uncommonly particularly with respect to the important arc stability. This disadvantageous situation is improved markedly, according to the present invention, by the shielding gas being additionally mixed, in a proportion range of no more than from 20 to 5000 vpm, preferably from 50 to 3000 vpm (from 0.005 to 0.30 % by volume) with additions of heavy noble gases (Kr, Xe) and/or stable, simple biatomic or triatomic non-noble gases (H2,O2, CO2, N2O, NO2 and the like) and/or gaseous, stable organic compounds, preferably C1 to C4 hydrocarbons (CH4, C2H4), having ionisation energies between 8 and 17 eV, preferably 8 and 14.3 eV.
