A plastics pour spout fitment (3) has not only a pour spour (4) thereof welded to plastics-coated paperboard packaging material (2), but also has a plunger (14) welded to a disc (8) of the material (2), the disc (8) being defined by a ring of weakening (6) in the material. Following purely linearly axially inward displacement of the plunger (14) relative to the pour spout (4), preferably followed by rotation of the plunger (14) about the axis A of the fitment (3) relative to the spout (4), to detach the disc (8) from the remainder of the material (2), the plunger (14), and thus the disc (8), are removed from the pour spout (4) as a screw cap (12) is removed from the spout (4).

A flux-cored wire for different-material bonding which, when used for bonding an aluminum-based material to an iron-based material, heightens the bonding strength and has satisfactory welding efficiency; a method of bonding different materials; and a joint obtained by the method. In particular, the method is for use in the fusion welding of a high-tension steel material to a 6000-series aluminum alloy material, which are high-strength different materials, and in the bonding of a zinc-plated steel material. One embodiment employs a flux-cored wire comprising an aluminum sheath and a flux with which the inside of the sheath is filled, wherein the flux is a fluoride composition containing a specific amount of AlF3 and containing no chloride and the sheath comprises an aluminum alloy containing 1-13 mass% silicon. Use of such flux-cored wire in the fusion welding of a high-tension steel material to a 6000-series aluminum alloy material, which are high-strength different materials, gives a high bonding strength.

A method of thermally spraying at least one adherent metallic coating onto an unroughened cleansed aluminum or aluminum alloy substrate to produce a coated substrate, comprising: wire-arc thermally spraying of melted metallic bonding droplets and fluxing particles onto the substrate using air propulsion to concurrently adherently deposit flux particles and bonding droplets, the spraying using air propulsion and a wire feedstock having a core and a sheath, the wire core being constituted of both metal powder readily metallurgically bondable to the substrate and a fluxing powder that readily deoxidizes the substrate, the wire sheath being constituted of pliable metal that is metallurgically compatible with the core metal powder, the fluxing powder having a halide salt chemistry effective to deoxidize the substrate upon contact of the melted fluxing powder therewith, said fluxing powder and bonding metal having a particle size that more uniformly promotes distribution throughout said spray. A flux cored wire for use in thermal spraying of aluminum or aluminum alloy substrates, comprising (a) a powder core mixture consisting of (i) a metal bonding powder effective to metallurgically bond by an exothermic reaction with the substrate when the bonding metal powder is in a melted condition, (ii) a fluxing powder effective to strip aluminum oxides from said substrates when in the melted condition, (b) a pliable metal sheath encapsulating the powder mixture and having a composition that is metallurgically compatible with the bonding metal and also is effective to react with aluminum surfaces to form intermetallics.

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.

Automatic fixed position pipe welding is carried out by gas-shielded electric arc welding with a novel flux-cored electrode wire having a low-carbon sheel sheath containing a core filling of, by weight, 16-17 percent ferro manganese, 10-11 percent ferro silicon, 1-4 percent manganous oxide, 1/2-1 percent potassium aluminum fluoride, and the balance rutile. The wire exterior is shiny and metallic-appearing, and the wire is configured to have folded-in edges.

A novel flux-cored welding wire for gas-shielded electric arc welding is described characterized by a shiny, metallic-appearing surface on a low carbon steel sheath and containing within its core as essential flux ingredients 6-20% ferro manganese, 6-20% ferro silicon, 1-20% manganous oxide, 1/2-5% of a flouride compound, and the balance rutile. The wire is especially useful in out-of-position welding to produce sound welds combining good strength and high notch toughness at subzero temperatures.
