The present disclosure relates to an induction sealing system for heat sealing packaging material for producing sealed packages of pourable food products, said sealing system may include a sealing jaw and a counter-jaw. In some embodiments, the sealing jaw may include at least one inductor device having at least one active surface configured to contact said packaging material; at least one flux-concentrating insert; a supporting body including heat-conducting material, said supporting body housing, said at least one inductor device and said flux-concentrating insert; and an interactive surface configured to press against said packaging material. In some embodiments, the counter-jaw may include at least one pressure pad made of elastomeric material, said at least one pressure pad configured to provide a counter pressure to the sealing jaw, wherein said at least one pressure pad has an arched convex contact area with height in the direction towards the sealing jaw.

A barn curtain having a transparent panel and a non-transparent panel is prepared by a welding machine. The welding machine has an inner heater assembly including a first roller wheel, an inner plate assembly having a lower inner plate and an upper inner plate spaced apart from the lower inner plate in a vertical direction, and a heater, and a first roller assembly including a second roller wheel aligned with the first roller wheel. A side of a transparent panel is fed through the lower inner plate and a side of a non-transparent panel is fed through the upper inner plate. The plates are heated with the heater to partially melt the side of the transparent panel and the side of the non-transparent panel. The side of the transparent panel and the side of the non-transparent panel are pressed between the roller wheels and joined.

A process for placing a circuit array on a sheet having adhesive during a pick and place operation in which a vacuum is used during its placement to minimize air bubbles between the adhesive layer and the circuit array.

A joining material for laser welding, a laser welding method using the same, and a laser joined body using the laser welding method. The joining material includes a polymer matrix and a needle-shaped inorganic filler. The polymer matrix includes a polypropylene resin having a melt index of 80 g/10 min or more to 95 g/10 min or less as measured at a temperature of 230° C. and a load of 2.16 kg, and the needle-shaped inorganic filler has an aspect ratio of 10:1 to 20:1.

A friction stir spot welding apparatus including a controller that (A) operates a rotary driver and a tool driver such that a pin and a shoulder are brought into contact with a welded workpiece; (B) operates, after the step (A), the rotary driver and the tool driver such that the pin separates from the welded workpiece; and (C) operates, after the step (B), the rotary driver and the tool driver such that the pin advances toward the welded workpiece. The controller controls the tool driver such that pressing force applied to the welded workpiece from the pin and the shoulder in the step (C) is smaller than that in the step (B) and/or controls the rotary driver such that rotational frequencies of the pin and the shoulder in the step (C) are lower than those in the step (B).
