The Spot Weldability of Carbon Steel Sheet AM Al-Mukhtar, Q Doos Abstract The specimens of thickness 0.8 mm carbon steel number 1.8902 in a strip form were
welded. The strips of lap joints and curved peeljoints configurations have been welded.
The welding parameters such as weld current and weld time have been investigated. The
relation between the weld area and the joint strength properties has been presented. The
obtained results were showing that the weld joint strength and the molten area (weld
nugget volume) highly increase with the increasing of weld current. Therefore, the
correlation between the maximum load (joint strength) and area has been given. The
reliable weldability under the tensile and shearing loading was considered. Therefore, the
new limits of weldability have been presented to consider these two types of loading.
Moreover, the experimental results were compared with the empirical relations that
consider the sheet thickness only. Advances in Materials Science and Engineering |
