A welding apparatus for use in welding first and second sheets of material together includes a seal die, a platen, a control unit, and a power source adapted to provide energy to the seal die. The seal die is made of a conductive material and is configured to impart thermal-mechanical energy to the first and second sheets of material. The seal die includes a bottom surface configured to contact the first sheet, an inner edge, a chamfer extending between the bottom surface and the inner edge, a first blend radius, and a second blend radius. The first radius extends between the chamfer and the bottom surface, while the second radius extends between the chamfer and the inner edge. The platen is configured to support the second sheet, while the control unit is programmed to cause the seal die to be directed towards the platen.

A tool coupler for a clamping system, in particular for clamping a welding saddle to a plastic pipe, including a body having a drive end and an opposite output end, a first positive engagement feature being formed at the drive end and a second positive engagement feature being formed at the output end, the first positive engagement feature being adapted to engage a torque wrench to drive the body, and the second positive engagement feature being adapted to engage a slotted strap shaft of a tensioning ratchet of a clamping system to transfer torques by positive engagement.

A tool for use in fusing an outlet fitting in the side wall of a plastic pipe has a base with three perpendicular guide rods. A movable plate is reciprocated on the guide rods in response to manual operation of a rack-and-pinion. The movable plate has a hole oriented to align a drill adapter and an outlet fitting adapter which are interchangeably inserted into the hole on an axis extending through a predetermined point on the longitudinal axis of the pipe. A retractable ratchet strap tightly girts the pipe to secure the tool against the pipe. The ratchet strap assures that the tool always maintains its original orientation on the pipe and the hole assures that interchanged drill and outlet fitting adapters are always returned to their original orientation in the tool. Therefore, the outlet fitting is always fused in its proper orientation in the pipe.

A laser welding apparatus is provides that includes: a support member including a heat generation portion which has a size that is limited to correspond to a size of a welding area of a plurality of plastic components and is made from a material that absorbs a laser beam and generates heat, and which generates heat of a temperature that is equal to or greater than a melting temperature of the plastic components; a laser beam irradiation unit for converging a laser beam to be transmitted through the plurality of plastic components, and irradiating the laser beam toward the heat generation portion through the plurality of plastic components; and a welding controller for causing a laser beam to be irradiated at the heat generation portion using the laser beam irradiation unit to thereby cause the heat generation portion to generate heat, and welding abutting faces of a welding area of the plurality of plastic components with heat that is generated.

A film fin sealing device is disclosed herein which may have a groove defining a base. The base of the groove of the fin sealing device may be oriented at a skewed angle with respect to a longitudinal direction of the conveyor of a heat sealing machine. Edges of a thermoplastic sheet or two stacked layers of thermoplastic sheets are introduced into the groove of the film fin sealing device and placed in contact therewith to both heat and fuse the distal edge portions of the thermoplastic sheet(s) to join the edge portions thereof to form a fin seal.

A socket fusion jig includes a pipe saddle and coupling saddle spaced apart. Rotation of a handle causes the pipe saddle and coupling saddle to move laterally relative to one another so that the pipe held in the pipe saddle may be fused to the coupling held in the coupling saddle.

A drive system for driving an automatic welding machine for joining the edges of sealing sheets, comprising pressing/advancing rollers located vertically opposite one another and driven by a shared drive motor, downstream of which a transmission gear mechanism is connected, and an upper pressing/advancing roller is disposed rotatably about a roller rotational axis on a tensioning arm of the automatic welding machine, which is pivotable about a tensioning arm axis, and a lower pressing/advancing roller is disposed rotatably about a roller rotational axis on a frame of the automatic welding machine, which is supported by at least two drive rollers, wherein the drive motor and the transmission gear mechanism are rigidly attached to the frame, and the drive motor comprises a motor armature including a protruding rotational shaft, and the transmission gear mechanism comprises a rotatable protruding input shaft and output shaft.
