2 . The energy converting film of claim 1 , wherein the polymer component comprises a thermoplastic polymer, a thermoset polymer, or a mixture thereof.

3 . The energy converting film of claim 2 , wherein the thermoplastic polymer is a polyamide-imide, a polyethersulphone, a polyetherimide, a polyarylate, a polysulphone, a polymethacrylate, a polyvinylchloride, an acrylonitrile butadiene styrene, a polystyrene, a polyetherimide, or a combination thereof.

4 . The energy converting film of claim 2 , wherein the thermoset polymer is a polyphenylene ether, a nylon 6,6, a nylon 11, a polyphenylene sulphide, a polyethylene terephthalate, a polyoxymethylene, a polypropylene, a high-density polyethylene, a low-density polyethylene, a linear low-density polyethylene, a chlorinated sulfur polyethylene, or a combination thereof.

5 . The energy converting film of claim 1 , wherein the polymer component of the energy converting film comprises a polyolefin, a polyurethane, a polyester or a combination thereof.

6 . The energy converting film of claim 1 , wherein the susceptor component comprises an electrically-conductive material, a ferromagnetic material, or a mixture thereof.

7 . The energy converting film of claim 1 , wherein the susceptor component comprises a metal, a plastic, a ceramic, a carbon, or a mixture thereof.

8 . The energy converting film of claim 7 , wherein the metal comprises, iron, copper, aluminum, nickel, cobalt, carbon steel, alloys thereof, or mixtures thereof.

9 . The energy converting film of claim 8 , wherein the carbon comprises a carbon nanotube, a conductive carbon, or a mixture thereof.

10 . The energy converting film of claim 8 , wherein the metal comprises stainless steel.

11 . The energy converting film of claim 10 , wherein the stainless steel is a 300 series stainless steel, a 304 series stainless steel, a 400 series stainless steel, or a mixture thereof.

12 . The energy converting film of claim 7 , wherein the ceramic is silicon carbide.

13 . The energy converting film of claim 7 , wherein the plastic is a polar plastic.

14 . The energy converting film of claim 13 , wherein the polar plastic comprises a polyamide, a polycarbonate, a poly(methyl methacrylate), an acrylonitrile butadiene styrene, a polyvinyl chloride, a polyketone, an ethylene-vinyl acetate, or a combination thereof.

15 . The energy converting film of claim 1 , wherein the susceptor component comprises a fiber, a particle, a flake, or a mixture thereof.

16 . The energy converting film of claim 15 , wherein a thickness of the flake or a largest diameter of the particle or fiber is independently in a range of from about 10 nm to about 25 μm.

17 . The energy converting film of claim 1 , wherein the susceptor component is configured to generate heat upon exposure to a frequency in a range of from about 60 Hz to about 100 MHz.

18 . The energy converting film of claim 1 , wherein the susceptor component is configured to generate heat upon exposure to a frequency in a range of from about 200 KHz to about 10 MHz.

19 . The energy converting film of claim 1 , wherein the susceptor component is in a range of from about 0.1 wt % to about 80 wt % of the energy converting film.

20 . A welded product of the energy converting film of claim 1 .

21 . A weldable assembly comprising:
a first polymeric film; and an optional second polymeric film; and the energy converting film of claim 1 , wherein the energy converting film is in contact with the first polymeric film and the second polymeric film, the energy converting film.

22 . The assembly of claim 21 , wherein the first polymeric film, the second polymeric film, or both independently comprise a polyolefin, a polyurethane, a polyester or a combination thereof.

23 . The assembly of any one of claim 21 , wherein the first polymeric film, the second polymeric film, or both, are multi-layer structures.

24 . A method of making a welded assembly of the weldable assembly of any one of claim 21 , the method comprising:
contacting the first polymeric film and the second polymeric film with the energy converting film; exposing the first polymeric film, the second polymeric film, and the energy converting film to a source of electromagnetic radiation; and welding the energy converting film to the first polymeric film and the second polymeric film.

25 . The method of claim 24 , wherein during welding the first polymeric film, the second polymeric film, or both, melt to a lesser degree than the energy converting film.

26 . The method of claim 24 , further comprising compressing the energy converting film between the first polymeric film and the second polymeric film.

27 . The method of claim 24 , wherein the welding comprises using an induction welder comprising an induction coil.

28 . The method of claim 27 , wherein the induction welder is located proximate to an exterior surface of a tubular and the energy converting film is located proximate to an interior surface of the tubular assembly.

29 . The method of claim 24 , wherein the first polymeric film and the second polymeric film are joined by a lap weld, a butt weld, or a prayer weld.

30 . The method of claim 24 , wherein the first polymeric film and the second polymeric film are free of a void therebetween.

31 . The method of claim 24 , wherein contacting the first polymeric film and the second polymeric film with the energy converting film comprises:
overlaying a portion of the first polymeric film and the second polymeric film to form an intersection therebetween; and applying the energy converting film over the intersection.
