Product Description

H-beam box beam gantry automatic submerged arc welding machine is a device for automatic submerged arc welding of assembled H-beams (assembled and spot welded on the Assembly machine).
The H-beam/T-beam/box beam is placed on the workpiece bracket, and the welding seam is in a boat-shaped welding position at an inclination of 45°. The welding arm equipped with the submerged welding head and the flux recovery device is horizontally and Moving up and down, the welding nozzle on the machine head is aligned with the welding seam of the H-beam, and the automatic tracking device of the welding torch makes the welding torch walk straight on the rail of the gantry for automatic welding.

FAQ:
1. What is the difference between submerged arc welding and gas shielded welding?
Submerged arc welding is a welding method in which the arc burns under the flux layer.
It has the advantages of stable welding quality, high welding productivity, no arc light, less smoke, etc., and has become the main welding method in the production of important steel structures such as pressure vessels, pipe section manufacturing, box beams and columns.

Gas shielded arc welding is a kind of arc welding that uses gas as the arc medium to protect the arc and the welding area,It is called gas shielded arc welding, or gas shielded welding for short.

The main difference is that submerged arc welding relies on flux as a protection against oxidation. When the coating is separated from the electrode, the coating is automatically buried in the weld to prevent oxidation during welding; while gas shielded welding is protected by an external gas source such as carbon dioxide. The gas prevents oxidation, and is then welded by wire welding.

2. What equipment does the whole H-beam production line include?
CNC Flame Plasma cutting machine-Assembly machine with automatic or manual spot welding machine-Gantry type Cantilever H beam submerged arc welding machine-Flange hydraulic or mechanical straightening machine-Shot blasting machine-End face milling machine,etc.
