It helps regulate energy supply and demand, and facilitates distributed renewable energy (DER) utilization by engaging distributed storage technologies for local grids, or microgrids [1, 2]. According to the BP Energy report [3], renewable energy is the fastest-growing energy source, accounting for 40% of the increase in primary energy.

A variant of the arc method is the short cycle method. The welding time is shorter, generally less than 0.1 second, and the method can be used both with and without a ceramic ring and/or shielding gas. The sheet can be thinner in proportion to the diameter of the stud (down to 1:8), and the process is not sensitive to the surface coating of the sheet, …
