Tube seam annealing system in line seam queaching machine
Seam Annealer—weld heat treat of HF welded tube and pipe
The seam annealing process is dedicated to the normalization of the Heat Affected Zone (HAZ). In many cases the welding line must be annealed after the welding process to prevent a failure point and provide a uniform metallurgical results.
Both the American Petroleum Institute (API) and the American Society for Testing and Materials (ASTM) specify that on certain grades of pipe, the weld seam needs to be processed in order to ensure that no untempered material remains.

High Frequency Welder for H Beam Line
H.F Welder welding H Beam
Using Solid state high frequency welder contact type to welding web and flange together.According to the web height and thinkness ,flangle width and thinkness is different, the HF welder size is different.
Especially weldling carbon steel material.
Need 2 set of high-frequency welders,they have synchronous control function, and work stably without interference with each other.
The inverter output cabinets of the two high-frequency welding machines are all installed on the three-dimensional adjustment device, and the contact welding contacts are controlled by constant pressure, so that the synchronization and consistency of the contacts are good.
Excellent cross-section performance, customized cross-section size according to user requirements, convenient production of special-shaped H-beam, and increased ratio of flange thickness to web thickness.

1000KW large diameter metal tube welding machine–Series connection type Solid state high frequency welder
There is no need to add a step-up/step-down rectifier transformer at the input end of a solid-state high-frequency welding machine. Compared with an vacuum tube welding machine or a parallel solid-state high-frequency welding machine, it has a more obvious energy-saving effect (compared to an electronic tube welding machine, at the same level). Under welding conditions, power saving ≥30%).
