Spot and Projection Welding

Description:

Artech Welders Private Limited took roots in 1994 with the dream of manufacturing Capacitor Discharge (CD) projection welding machines. Powered by a vision to blend power saving with aesthetics, Artech has today germinated into a force to reckon with in the field of resistance welding. A wide range of end users embrace the quality welding that Artech offers. They include manufacturers of automobile sheet metal components, stainless steel impellers, sheet metal products, diamond tools like cup wheels and core drills, hollow metal doors, auto electricals, control panels, stainless steel cookware and kitchenware to name a few. – PowerPoint PPT presentation

Types of Welding

Spot Welding...
  • In Spot Welding the pieces to be joined are
  • clamped between two electrodes under force,
  • and an electrical current is sent through them.
  • Force is applied before, during, and after the
    application of current to prevent arcing at the
    work piece.
  • In spot welding fusion of faying surfaces of a
    lap joint is achieved at one location by opposing
    electrodes

Advantages of Spot Welding
  • Spot welding is quick and easy
  • No need to use any fluxes or filler metal
  • Multiple sheets joined together at the same
    time.
  • No dangerous open flame
  • Saves production costs.

Applications of Spot Welding
Nuts Bolts
Join two Metal Sheets
Automobile Industry
To make Batteries

Projection Welding
  • In Projection welding size and shape of
    individual welds are determined by the presence
    of projections, embossments or intersections on
    the metals to be joined.
  • Metals are heated and coalescence is achieved
    not through the use of an arc, but through the
    metals resistance to electrical currents passing
    through them as they are held together with
    pressure by electrodes.
  • In projection welding the pieces to be joined are
    clamped between two electrodes under force, anan
    electrical current is sent through them.

Advantages of Projection Welding
  • Simultaneously we can make any number of welds
    in heavier materials easily.
  • Welding can be made in metals that are too thick
    to be joined by spot welding.
  • Lower Electrode Maintenance.
  • Lower amount of current and pressure
    needs to joint metals.
  • Faster and Quicker and used in
  • mass production
