Aluminum RV’s,Motor Homes, Flatbeds and Truck Trailers

Focused-Melt Resistance Welding (FMRW™) benefits for application in Aluminum RV and Mobile Homes, and Flatbeds/Truck Trailers

 

Why you should use IWSL’s new FMRW™ Cosmetic Welding Process

Benefits:

  • Resistance weld process is the least expensive method of joining in any large volume factory.

  • IWSL’s FMRW welding enables achieving good process stability in a factory
  • Large specially engineered electrode contact area with part keeps electrodes from getting too hot, so they last long
  • “500 to 1000 welds between electrode redressing operations” unlike “30-50 welds between redressing operations” by other weld manufacturers for aluminum alloy spot welding
  • Only weld process for aluminum alloys that generates cosmetic welds to meet a target weld strength and target weld durability

FMRW™ Welded Aluminum Structures Are Good For Fatigue Applications in Trucks and Tractor Trailers

Real-world Test: FMRW™ Welded Part Pass fatigue test specified by a flatbed manufacturer

fatigue resistant aluminum weld

6.25 mm thick 6061-T6 alloy FMRW weld after a peel test; cosmetic, strong and fatigue resistant

Aluminum structure fatigue applications

6.25 mm thick 6061 T-6 alloy plate FCR welded to a 6.25 mm thick 5454 H-34 alloy plate.

This Strong-Al (FCRW) weld passed fatigue test requirements of a flatbed manufacturer (0 to 1700 pounds @ 1 cycle/sec for 30,000 cycles) *Covered by IWSL’s US and International Patents, PCT coverages and Patent Pending Applications

    Unusually Cosmetic and Strong Aluminum Alloy Welds

    • Dimpled appearance at the weld projects outwards; can be patterned to match present riveted assembly appearance if desired
    • Weld strengths are four times as much as required by AWS D17.2 and double the weld strength other welding manufacturers can attain on the same sheet thickness

    Now Aluminum Alloy Sheets can be spot-welded close to the edges

    Spot weld at edge of aluminum alloy sheet Strong-Al Weld Microstructure shows: • Large weld nugget (10 mm diameter) in a thin sheet (1.6 mm) • Non-melted outer surfaces improve the strength and corrosion resistance of the welded structure
