2 when current is applied weld nuggets similar to spot welding are formed at the projections.

Projection welding ppt. Upset Weld After Welding. UNIT-III BY SURENDRA KUMAR Department Of Mechanical Engineering 2. 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.

EZ Zone Welding Tape from Aquasol Welding - EZ Zone Tape eliminates the worry of adhesive contaminating the weld area when sealing the root gap between pipes because it is composed of two outside adhesive sections separated by an adhesive-free center zone. Resistance projection welding RPW. EZ Zone Tape allows a welder to effectively prevent contamination in the weld joint and increase the number of pure finished welds.

Fiback is flexible heat resistant and halogen and fluorocarbon-free enabling it to be a complete solution for plate sheet and pipe welding needs. Adaptability for Automation in High-Rate. Projection welding has fewer variables that affect the resistance welding process as compared to spot welding.

1 start of operation contact between parts is at projections. Metallographic aspect of projection welded nut 12 5 times magnification. Weld Backing Tape from Aquasol Welding - Fiback Fiberglass Weld Backing Tape is an innovative substitute for traditional back purging methods that provides protection to the backside of the weld environment and ensures a high quality finish.

A Resistance projection Welding bA welded bracket c d Projection welding of nuts r threaded hosses and stack 21. Resistance Projection Welding A resistance welding process in which coalescence occurs at one or more small contact points on parts. Projection welding is a resistance welding process of joining two sheets or a sheet and a thick component or a small component like nut to a big body like automotive chasis by making raised portions or projections on one of the components where weld nugget is.

Cold Welding Pressure is applied to the workpieces through dies or rolls Preferably both work pieces should be ductile The work pieces should cleaned thoroughly Can not join dissimilar metals Fig. Projection Welding In Projection welding size and shape of individualwelds are determined by the presence of projectionsembossments or intersections on the metals to bejoined. Resistance Projection Welding RPW is developed by introducing high electrical resistance at a joint by embossing one or more projections on the surface to be welded Weld nuggets are similar to spot welding Fig.

Flux Cored Arc Welding FCAW 114. Shelded Metal Arc Welding SMAW 111. The roll bonding or cladding process Ultrasonic Welding Surfaces of the two components are subjected to a static forces and oscillating shearing force Produces a strong solid-state bond Versatile.

Flash Weld After Welding Reference. The most important variables of this assembly technique are the quality of the projections and the response of the cylinder as the projection collapses during the welding time. Non Consumable Electrode.

Projection welding is a process in which contacting metal surfaces are joined by the heat obtained from resistance to electric current. Projection Welding 9. Projection Welding Machine - An overview of the projection welding machine of Artech Welders Private Limited.

Metals are heated and coalescence is achieved notthrough the use of an arc but through the metalsresistance to electrical currents passing. A Vocational Training Presentation on Welding From SIMPLEX CASTING LTD. 2 This process is not applicable to all types of workpieces the composition of workpiece has to be considered while choosing this welding process.

The principle applied is the same seen at electric resistance spot welding ERSW but in this particular process the nut has some small protuberances which are responsible to concentrate the electric current flow to a. Disadvantages of Projection Welding. Only a skilled person can form projections of different required shape like spherical projections.
