About The Battery Joint

battery joint

Got an email from one of my ERG members that asked about the battery joint.  Does anyone know how could the maker make this joint without any solder? Do you know what kind of tools the maker use to weld it? Thanks in advanced.

    Thanks for giving chance to express answer of given issue.
    Actually, The maker sold or joint the plate by spot soldering or welding. which is easily to sold any metal thin plates . To be noted spot solder machine is easy to make by high ampere transformer. Like, primary winding is simple but secondary winding make with only high ampere wit few voltages.

    thanks you

    I saw a friend of mine doing this kind of electrical welding. in my country they call the the dot welding..that means they use negative and positive terminals and the machine just add a welding that looks like a dot...but they do the welding without the battary in..they just weld the shell from the outside then add the battary inside. if they do it the other way around the battary would explode.
