Photovoltaic welding strips belong to welding rods. Plasma arc only penetrates the base metal to form a welding pool, which is commonly used for welding plates with a thickness of 0.8-3mm; The latter form of plasma arc only penetrates the sheet metal, forming a keyhole shaped melt pool, which is commonly used for welding 3-12mm thick sheets. In addition, there is also low current micro beam plasma arc welding, which is particularly suitable for welding thin plates with a thickness of 0.02-1.5mm.
Welding strip offset can affect the normal flow of current and cause component power attenuation.
In the production process of photovoltaic panels, various defects may occur due to uncontrollable factors such as welding process fluctuations and electrode oxidation, and offset of the welding strip is one of them. Welding strip offset can affect the normal flow of current and cause component power attenuation. The welding strip inspection of existing photovoltaic panels mainly relies on manual sampling inspection during the production process, which is inefficient.
What is the impact of offset of photovoltaic panel solder strips, and the main producing countries of tin coated copper strips
The main producing country of tin coated copper strips is China.
Photovoltaic solder strip, also known as tin plated copper strip or tin coated copper strip
Splitting busbars and interconnecting bars are used to connect photovoltaic modules and cells, playing an important role in conducting and concentrating electricity.
Solder strips are important raw materials in the welding process of photovoltaic modules. The quality of solder strips directly affects the efficiency of current collection in photovoltaic modules, and has a significant impact on the power of photovoltaic modules.
During the process of connecting battery cells in series, the welding strip must be firmly soldered to avoid the occurrence of false soldering.
