  • Description

    ATLANTA, Ga., Aug. 28 -- The Lockheed-Georgia Company in Marietta has set up the first weldbonding assembly line to be used by any company in the U.S. and the process could revolutionize the way airplanes are made.

    What is involved in weldbonding? An adhesive paste is placed between two pieces of metal to be bonded. The metal is spotwelded (electrically fused) at many contact points. The joined pieces ar then put into a commercial type oven and the adhesive is cured. When these are completed, weldbonded assemblies are born.

    Weldbonding does the same job as riveting, but does it better. Compared to riveting, it is faster, cleaner, quieter, and cheaper. The advantages of weldbonding include a stranger mating of metal parts and fewer required man-hours in production. Metals joined by weldbonding are immune to two common fatigue problem: peel, and sonic vibrations. This is a definite plus in building high performance aircraft.

    Weldbonding has a variety of applications. Lockheed's assembly line is presently being used to manufacture general purpose storage containers for the Air Force. Because weldbondig has been successfully tested and uses on parts of production aircraft, it will be used more extensive in future production programs at Lockheed-Georgia.

    Lockheed-Georgia was awarded United States Letters Patent 3,829,416 in the names of Dallas Fields and Maxwell Shatzen senior manufacturing research engineer on August 13, 1974, for an adhesive formula used in welbonding.

    SYNOPSIS: THIS IS AN ASSEMBLY LINE AT A MAJOR AIRCRAFT MANUFACTURING PLANT, BUT IT IS NO ORDINARY ASSEMBLY LINE.

    THESE MEN ARE BUILDING GENERAL PURPOSE STORAGE CONTAINERS UTILIZING A PROCESS CALLED WELDBONDING. IT IS THE FIRST ASSEMBLY LINE OF ITS KIND IN THE U.S.

    MANY FEEL THAT THIS PRODUCTION TECHNIQUE, IN USE AT THE LOCKHEED-GEORGIA COMPANY IN MARIETTA, COULD REVOLUTIONIZE THE WAY AIRPLANES ARE MADE.

    WELDBONDING COMBINES TWO WELL PROVEN TECHNIQUES: SPOTWELDING AND METAL ADHESIVE BONDING. THE RESULT IS A PROCESS WHICH DOES THE SAME JOB AS RIVETING BUT DOES IT QUIETER, CLEANER, FASTER, AND CHEAPER. THE ADVANTAGES OF WELDBONDING INCLUDE A STRONGER MATING OF METAL PARTS AND FEWER REQUIRED MAN HOURS.

    THE PROCESS INVOLVES THE USE OF A LIQUID ADHESIVE PLACED BETWEEN TWO PIECES OF METAL TO BE BONDED AND USING ELECTRICAL IMPULSES TO BIND THE PIECES IN SPOTS. THE ELECTRODES MELT OR FUSE THE PIECES AT THE POINT OF CONTACT.

    JOINED METAL PARTS ARE THEN PUT INTO A COMMERCIAL TYPE OVEN AND THE ADHESIVE IS HEAT CURED. THE OVEN BECOMES A KIND OF WOMB WHICH GIVES BIRTH TO WELDBONDED ASSEMBLIES.

    CONTRUCTION OF THIS TYPE MAKES JOINED METAL PIECES IMMUNE TO TWO COMMON FATIGUE PROBLEMS: PEEL AND SONIC VIBRATIONS AND WOULD PROLONG THE LIFE OF METAL USED IN AIRCRAFT PRODUCTION.

    WELDBONDING HAS BEEN SUCCESSFULLY USED ON PORTIONS OF PRODUCTION AIRCRAFT AND IS EXPECTED TO BE MORE EXTENSIVELY USED IN MAJOR AIRCRAFT PRODUCTION PROGRAMS AT LOCKHEED-GEORGIA IN THE FUTURE.
