| Summary: | Torch brazing is one
method of brazing based on using a heat source for joining metals. This method is classified as a liquid-solid
state thermochemical process and is generally used in joining pipes. This
process heats the brazing filler metal until it reaches the melting point
without exceeding the melting point of the base metals to be joined. After
cooling, the filler metal grants a strong joining capacity to the base metal.
Depending on the amount of pressure and the length of lap joint in the brazing
process the quality of the joint will be affected. This research will
investigate the effect of pressure and the length of the lap joint on the
material strength properties of BJ DD2 steel and C12000 copper. An optimal
configuration between pressure and the length of lap joint will be determined
from the result of shear load and joint clearance, which are the factors that
affect joint strength and the process of brazing. The greater the shear load
and the smaller the joint clearance, the higher the joint strength will be. The
result shows that the pressure has a larger effect than the length of the lap
joint for dissimilar metal joining using torch brazing. |
