Technical Field

[0002] As the name implies, a photovoltaic ground pile reinforcing sheet is a sheet-like structural member used to enhance the performance of a photovoltaic ground pile. It is usually installed between the photovoltaic ground pile and the foundation to improve the compressive performance and stability of the ground pile by increasing the contact area and dispersing the load.
[0003] In the prior art, when welding a photovoltaic ground pile reinforcing sheet, during the welding process, partial arc welding needs to be carried out along with the structure of the reinforcing sheet.
