Projection Welding Advantages

Welding current and pressure required is less. One is the inability to contain the molten weld nugget as it is forms.

Burrs in projection welding be it Capacitive Discharge AC or MFDC resistance welding are caused by several factors.

Projection welding advantages. Projection welding is same as spot welding except a dimple is produced on work pieces at the location where weld is desired. It is possible to weld more than one spot at a given time. Iii The welds may be placed closer than spot welding.

A superior heat balance compared to other resistance welding methods Ideal for scenarios requiring thick pieces of metal to be joined together. The process allows for more than one weld to be completed at one time thereby increasing production output. Projection welding offers a wide range of benefits over more traditional welding methods including.

Spot welding is also used in the orthodontist clinic where small scale spot welding equipment is used. Advantages of projection welding process. Up to about 6 welds per cycle can be made which substantially reduces the cost of manufacture.

The large number of welded at single. A small amount of pressure is applied through electrode on welding plates. Advantages of projection welding.

It is quick and easy. Now the work pieces held between electrode and a large amount of current pass through it. It helps in obtaining a satisfactory heat balance.

The number of welds depends on the number of projections that can come under the tip of the electrode. Benefits of Projection Welding Techniques Projection welding is very easy to maintain if the fundamentals are taken into consideration in the first place. Another is the weld interface may have been overheated.

Electrodes with large flat contact area can be used on the full or half identical area of the work piece. However one potential difficulty for the success of projection welding is the cleanliness of the parts or presence of surface films that can inhibit bonding. This process is very beneficial in many casessuch as -Thicker parts of metals which are difficult to welding by spot welding can be welded by projection welding.

A significant aspect of projection welding is the limited distortion associated with it which is certainly advantageous in terms of geometrical stability. Projection welding offers benefits such as. By this method multiple welds can be made simultaneously.

Multiple welds can be welded by this process at once. Advantages of Projection Welding. As less current passes through the electrodes the life of electrodes increases.

Flux is not used in this process. Even electrodes come with more lifespan. The life of electrodes is longer because of low current requirement.

A very important factor is that the full force must be maintained on the projections as they collapse. Advantages and limitations of the projection welding process. Advantages of Projection Welding The welding current intensely works on any individual parts using the profile or projection.

1 This projection welding requires a very small supply of current. Nuts and bolts are often assemble to. I More than one spot can be weld at a given time.

Ii Proper heat balance can be obtained easily. Heavy and weighed material can be joined and sheets of large thickness can be provided a good quality weld joint. Life of electrode is increased because of large contact surface.

Another application is also used in spot welding straps to nickel-cadmium or nickel-metal hydride cells to make batteries. Advantages of projection welding More than one spot weld can be made in a single operation so it is very fast. Advantages of Projection Welding.

Steel wire shopping carts wire racks and other cross wire products are all projection welding. The projection are able to guide the workpieces to be joined at appropriate places. Advantages of spot welding.
