What types of string welding machines are available on the market? What are their characteristics?

　　     With the rapid development of the photovoltaic industry, string welding machines, as the core equipment for photovoltaic module production, have become increasingly mature in terms of technology and market. Among the numerous brands and models of string welding machines, we can roughly divide them into two categories based on production capacity and process: conventional string welding machines and BC string welding machines. These two machines have their own advantages and meet the production needs of different types of photovoltaic modules.

     1. Conventional string welding machine

     Conventional string welding machines are common equipment on photovoltaic module production lines, mainly suitable for

the production of P-type and N-type modules. Its working principle is to accurately and quickly complete the welding of battery

cells and obtain the desired battery string through flat welding strips and infrared heating welding methods.

     Characteristics:

     Efficient: Adopting infrared heating method makes welding speed faster and improves production efficiency.

     Stability: The conventional welding method has been validated for a long time and the technology is mature, ensuring product

yield.

     Strong universality: suitable for the production of various specifications of P-type and N-type modules, meeting the needs of

most photovoltaic products on the market.

     2. BC string welding machine

     Unlike conventional string welding machines, BC string welding machines are designed specifically for the production of BC

battery components. There are special requirements for the welding temperature of battery cells, which require low-temperature

welding. Taking the Yuanwu series CTM-60BC string welding machine as an example, it has innovated in technology, ensuring the

welding quality of battery cells through a unique guide groove system, flexible welding strip treatment, and battery string

cooling system.

     Characteristics:

     Low temperature welding: Unique welding technology ensures that BC battery cells are welded in a low temperature

environment, ensuring that the performance of the battery cells is not damaged.

     Advanced technology: using a guide groove system and flexible welding tape processing to ensure precise and stable welding

of each battery.

     High precision: The addition of a battery string cooling system enables precise temperature control of the welded battery

string, ensuring product quality.

     Both conventional string welding machines and BC string welding machines are essential core equipment in the production

of photovoltaic modules. With the advancement of technology, we look forward to more technological innovations and

breakthroughs in the future string welding machine market.
