Steel structure production process
1.Cutting
Cut steel plate into pieces and connections by flame cutting machines (CNC, Semi-automatic flame cutting machines). Long strips will be used as web and flange plate, connections will be used as connected, reinforced or stiffening plate.
2.Assembly
Combine web and flange plate together through H-beams assembly machine, make tack welding. Keep the web plate in the middle line, do not be off the centre line.
3.Gantry submerged arc welding machine
Make welding by gantry submerged arc welding machine. Make sure the welding sequence and reduce the welding deformation.
4.Straightening machine
Start straightening on welding-finished H beams by straightening machine.
5.Connections process
Make holes on connected pieces by drilling machines. Make sure the hole size and precision.
6.Model
Fix and weld connections on H beams according to the drawing.
7.Welding
Make welding with CO2. Make sure the weld quality without welding flaw.
8.Surface treatment
Remove welding spatter and other defects.
9.Shot blasting
Make shot blasting on steel profiles. Make sure the blasting grade and quality.
10.Painting
Painting (or other anti-corrosion surface treatment)
11.Package
Pack steel profiles on steel pallet, which will be easy for transportation, loading and unloading jobs.
