Application and technology of super soft welding strip

Solar cells will have various welding defects in the welding process, but the most common welding defects should be debris, black spots and other phenomena. Whether manual welding or machine welding, fragments are always unavoidable in the welding process, so the rate of welding fragments has become an important indicator to assess the workshop. There are many factors that affect the welding fragments. This paper mainly considers the force between the welding strip and the battery, and studies the influence of the soft welding strip on the welding fragments.

Photovoltaic welding strip: product performance overview and biotechnology comparison

PV welding strip is a key component in the solar panel, which is an important factor to improve the efficiency and durability of the solar panel (Figure 2). The high efficiency and durability of the solar panel can only be achieved by using high-quality PV welding strips properly installed in the solar panel. High quality PV welding strip can also improve the production efficiency of solar panels and reduce the scrap rate.

Selection of pearlitic heat-resistant steel electrode

● High temperature performance of heat-resistant steel: (1) Creep resistance. Creep: plastic deformation of metal occurs slowly with the increase of time under the action of a certain temperature and stress. (2) High temperature endurance strength: the ability of metal materials to resist fracture under high temperature and long-term stress. (3) Creep brittleness (permanent plasticity of steel): brittleness tendency caused by combined action of temperature, stress and time. (4) High temperature oxidation resistance.

Selection of welding rod for Cr Mo pearlite heat-resistant steel

At present, Q345, Q370. Q390 and Q420 steel plates are mainly used as bridge structural steel in China, which conform to the standards of Low Alloy High Strength Structural Steel (GB/T 1591) or Structural Steel for Bridges (GB/T 714). In the manufacture of bridge steel structures, the commonly used welding methods are submerged arc welding and gas shielded welding, and a small amount of welding rod arc welding.
