Abstract:
This research aimed to compare between two soldering
techniques, conventional and laser methods. Metallic pieces were joined in
two ways: butt and overlap as known soldering designs.
The test pieces were soldered manually by 100 W electrical
tool. Similar numbers of pieces were soldered by Nd:YAG laser with 50
W. The test pieces, for both traditional and laser, were tested for tensile and
shear strengths.
The tensile test results showed the laser superiority on the
conventional method in loading and ductility. The shear test results showed
that laser still super in loading but ductility declined given traditional
electric soldering better ductility.
Nd:YAG laser soldering gave fast and clean joints in
addition to its ability to solder sensitive and intricate designs. Conventional
electric soldering method is more suitable for open, plane joints.
