Semi-welded plate heat exchanger plates use mature laser welding technology, which has the advantages of small welding deformation, small residual stress and high quality. Double-sided forming technology is used to reduce deformation and stress. The main application is used in refrigeration systems such as ammonia refrigeration, and other working conditions with corrosive media.

Advantages of laser welding:

1. The small processing range can control the energy input: the heat input is only 25% of the ordinary welding method, small thermal stress, small heat affected zone and small thermal deformation;

2. Narrow and smooth welds: can reduce or eliminate the post-weld treatment process;

3. The cooling speed is fast and the welding structure is fine, so the welding joint has good performance. Laser welding of stainless steel is easier to obtain high-quality joints than conventional welding, and the low thermal conductivity of stainless steel is easier to obtain deep-melting narrow welds;

4. The production process is easy to control: the sensor system monitors the processing in real time to ensure the welding quality;

5. Laser welding does not need to contact with the workpiece to avoid contact stress.

Our company can produce a variety of plate types of semi-welded plates and heat exchangers, the interface size from DN50-DN600, to meet the different needs of customers. There are also 304,316L stainless steel, titanium, nickel, SMO254, C276 and other plates, suitable for different working conditions.

Reapter was founded in 2014. In 2016, the component technology research and development team conducted research and research. It achieved automatic and stable welding of plate and shell heat exchangers, laser welding of semi-welded and double-walled plate heat exchangers in China. Break the monopoly of foreign technology.
