Projection Welding Temperature. Short length T joints eg. The projections should be properly formed without any partial shearing.
One of the main differences between conventional sheet-to-sheet resistance welding and projection welding is that projection welding is a dynamic process involving considerable movement of the upper electrode. When s t u d ying the effect of projection design on weld formation and weld quality many earlier researchers had to rely on experi-mental techniques such as consecutive cross sectioning and high-speed motion p h o t o g ra p h y. As the welding proceeds the spot s becomes larger.
Projection welding is generally used for projects with thicker materials around 0035 and thicker.
Points of welding zone starting from 1 mm distance are shown Fig. Work-pieces are held together. In the finite element model the temperature-dependent material properties were taken into account. 14 or 15 can be made by forming projections in.
