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.TRANSCRIPT
SPOT AND PROJECTION WELDING
Types of Welding
Welding Process
Arc Resistance Gas
Spot Seam Projection Flash
Spot 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
Spot Welding Machines
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
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.

Capacitor Discharge Projection Welding Machines
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
Application of Projection Welding
Diamond Segment Welding
Automobile Industry
Semiconductors
Fan Covers
Compressor Parts
Hollow Metal DoorsAuto Electricals
