Corrugated Web Automatic H Beam Welding Line

H beam welding production line is comprised of multi-head strip cutting machine (CNC strip cutting machine), H-beam assembling macine, H-beam welding machine, H-beam steel rectifing machine. All the production flow is automatic.

This machine is designed according to special character of vessel welding, its mainly consist of Gantry frame,slide structure,welding gun tracking device, Flux recovery system, electrical control system and Submerged welding machine.

SAW Advantage
One of the top advantages of submerged arc welding is that it prevents hot materials from splattering and splashing onto workers. Another benefit is that the flux prevents high levels of radiation from being emitted into the air. Submerged arc welding does not require added pressure to weld because it is already generated by the electrode. This application is excellent for quickly welding together thin metal sheets and creates a secure fusion between welds. This application also produces high productivity, fast travel speed, high repeatability, and quality results.

Corrugaed Panel Welding Machine

        Friendship Machinery is a world leader in automatic welding machine for steel fabrication field and industrial pipeline construction projects, providing an extensive range of equipment for a variety of project applications.
