Hot bar soldering. Hot bar(Pulsed heat Thermode) soldering is a joining technology where two pre-tinned parts are heated to the melting point of the tin. The joining technology results in a permanent electro mechanical joint. The required process energy is supplied by a thermode, also known as a Hot-bar.
Characteristics. Hot rolled (HR) 8620 bar is a low carbon nickel chromium molybdenum alloy is a low cost steel with good carburized properties. The nickel content contributes to case toughness at high strength with above average core toughness.pplications. Typical applications for hot rolled 8620 steel bar include gears, pinions, shafts, and other applications where it is helpful to have a steel that can be readily machined and carburized to controlled case depths.
