HSW SERIES SPOT WELDER PRODUCT COMPARISON
|
|
Junction condition depends a lot on the metal types and the electrodes, and also on the plunge pressure of the electrodes. All comparison tables and data do not guarantee that the model concerned can weld as well as mentioned. Please use this as reference only.

Spot-Welded Junction's Tensile Strength Evaluation |
| [ ABOUT THE EXPERIMENT AND HOW TO READ THE DATA ]
This experiment is conducted in order to know how strong is mechanically a welding junction welded with HSW Series. The strength value of a welding junction is affected by a lot of factors, so please use this as reference only.
The test pieces (experiment materials) are shown in the right picture. At the welding junction on the right, the right L-shaped part will be fixed using a vise. On the left side of the test piece, loops will be made and will be fixed with spot welding. The loop part, since it is a part to hang the hook of the spring balance for measurements, it will be different from the evaluated part; forces other than the ones on the shear direction will also work. Using the same load the test was done three times, and only if the results were the same for at least two times will the results be posted here.
Based on these strength evaluation results, the AAABC value of the product comparison on the upper half of this page is decided.
AA means enough strength mechanically;
for junction between metals, it means it can hold more than 20kgf of load. Also, for battery, it means it can hold more than 5kgf.
A means about half of AA in strength. It is not sufficient, but even at this level it is usable for some purposes.
B means it will not break down if it falls from about 2m height to a concrete floor, and it cannot hold more than 3kgf. It still can be used for temporary fixation such as soldering, and also for parts that need temporarily electrical connectivity and do not being applied to external forces.
C means it will be joint temporarily, and it will break down if it falls from about 2m height to a concrete floor. |
