THT company adopts the template positioning system, first uses the CNC spot welding machine to spot welding the support points of the valley, and then uses the CNC seam welding machine to seam the longitudinal direction of the plate pairs formed by the spot welding. There is a guide plate, which can ensure the welding quality of the arc-starting end and the arc-end end of the plate pair, and the welding quality of the plate pair can be verified by performing a mechanical performance test on each guide plate, so as to fully guarantee the semi-welded plate heat exchange. pressure capacity and safety performance.

The main equipment is high-end equipment in the industry, and many products and technologies are kept secret.

1. The laser welder (optical fiber laser generator) adopting the most advanced technology in the world is welded with modern laser welding technology. Jilin Province's major scientific and technological research project, won the second prize of Jilin Province's scientific and technological progress, and worked with Jilin University to develop welding technology. Compared with other welding methods, laser welding has the advantages of small heat affected zone, small deformation after welding, high welding quality (automatic detection in welding process), fast welding speed and relatively small residual stress.

2. Combining the international advanced welding technology with a large number of practical application cases in China, the first brand semi-welded plate heat exchanger in China has been built. At present, it is the only company in China that has obtained the B2---B3 level of the national safety registration certification of welded plate heat exchangers.

3. Welding of plate pairs

T Company adopts template positioning system, it firstly uses numerical control spot welder to spot weld the support point of the valley, and then uses numerical control seam welder to longitudinally seam weld the plate pairs formed by spot welding. Each plate pair is welded with a guide plate, which can ensure the welding quality of the arc starting end and the arc ending end of the plate pair, and the welding quality of the plate pairs can be verified by mechanical performance test of each guide plate, thus fully ensuring the pressure bearing capacity and safety performance of the semi-welded plate heat exchanger.

The equipment is mainly high-end equipment in the industry, and many products and technologies are kept confidential.
