,Introduction:
In this report I will be analysing welding processes that are appropriate for two
applications that I have chosen:
- Stainless steel die
- Low carbon steel plain cube
For each application I will justify and explain welding process in depth whilst covering
the multiple aspects of the welding process which include:
- Joint preparations
- Equipment and their functions
- Parameters
- Applications
- Joint preparations
- Health and safety
, Resistance Spot Welding (Stainless steel die)
Spot welding is a process in which two metals that are compatible with one another are
placed on top of each other and fused by electrodes on either side of the two metals.
When the electrodes are pressed onto the two-sheet metal an electrical circuit is
created allowing a strong electrical current to be generated and passed through the top
electrode into the material and into the bottom electrode. The electrical current
generates enough heat to melt two metals creating a weld that fuses both metals
together.
Common applications for resistance spot welding include the assembly of sheet metal
to create body panels for vehicles and the assembly of components in household
appliances.
Stainless Steel Die
The die is drawn as a template which
shows the lines where the sheet is
folded. This suggests the material
that’s being used is thin sheet metal
because it’s a material used in
bending and forming processes. The
die contains sides that overlap
(flanges) when the workpiece is folded
into shape, which justifies the use of
resistance spot welding to join the
surfaces together due to its
effectiveness at joining overlapping
sheets of metal. Furthermore, the metal components which are welded to the sheet
metal will not undergo distortion when resistance spot welding which allows for the
components such as the nut and threaded bar to remain functional.
Another reason why I justify using resistance spot welding for the stainless-steel die is
due to its high melting point which allows the heat produced by the welding process to
remain in the targeted area, resulting in reduced risk of distortion surrounding the
targeted area.
