STUDI MORFOLOGI FRACTURE SURFACE DENGAN HASIL SPOT WELDING
Abstract: This research
background with the desire of knowledge about what exactly the author Spot
Welding and is usually used in the automobile industry for the manufacture of
body of a car, the purpose of this study was to determine the time to do a good
press plate welding especially in Black and Galvanized plate with a thickness
of 1.2 mm . The first method of research conducted test process composition,
creation of test samples, perform welding with welding machine Spot Welding,
further testing of tensile and shear on each - each plate type, data
processing, data analysis form conclusions, and report generation. After doing
the research and the results obtained, a good press time at 3.5 seconds on each
plate with the current 26 Ampere, it is evident after tensile test on
galvanized plate and black plate worth gained the greatest diameter 4.3 mm for
the black plate and for shear test galvanized plate and black plate valued
largest diameter 5,35 mm for the black plate. From the above data it can be
concluded that at the time of press time spot welding greatly affect the value
of tensile and shear strength, in due time to the welding electrode material
emphasis will generate heat, thus forming clumps, the resulting heat will
affect the outcome of the weld.
