The intention of the measurements carried out was to gain fundamental knowledge about the character of the occurring dynamic forces on a spot welding

Parametric study of friction stir spot welding

Different studies deal with spot welding
effected parameters; see [2-8, 15].
As an element of novelty and complexity, in order to increase the sustainability of contact spot welding
electrodes was proposed the cladding by welding on the active area of layers enriched with carbides embedded in a copper matrix metal, thereby achieving a better consolidation and resistance to wear.
The conventional assembly method of side panels is spot welding
, which is formed by about 233 spot points.
An appliance manufacturer has replaced spot welding
of uncoated, coldrolled steel with TOX and eliminated the need to go through expensive degreasing stages prior to painting the finished housings.
Actually, the process of resistance spot welding
is complicated, involving mechanical, electrical, thermal, and metallurgical problems, due to the large number of interrelated variables.
Laser welding is a non-contact process, so the tip maintenance required for spot welding
guns is eliminated.
Remaining chapters discuss particular welding and joining techniques, including brazing and soldering, mechanical joining, adhesive bonding, gas-tungsten arc welding, variable polarity plasma arc welding, hybrid laser-arc welding, activating flux tungsten inert gas welding, friction stir welding, laser welding, resistance spot welding
, and electromagnetic pulse welding of magnesium to aluminum sheets.
12 shows the influence of spot welded connections on the deformed shapes, their strength characteristics and distance between the spot welding
For spot welding
case (see figure 1) these dimensions and therefore the allowable stress depends on welding process parameters.
