Complete production process of H section steel components


1. 下料 Cutting

 利用火焰切割设备(数控火焰切割机、半自动火焰切割机)将钢板切割成长条及连接件。长条为翼板、腹板用料,连接件为连接板、加强板、劲板等用料。

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. 组立 Assembly

利用组立机将翼板腹板组装成H型钢样式,并点固焊接。注意腹板居中,不能偏离中心线。

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. 龙门焊Gantry submerged arc welding machine

利用龙门焊机将H型钢焊接成型。注意焊接顺序,减少焊接变形。

Make welding by gantry submerged arc welding machine. Make sure the welding sequence and reduce the welding deformation.
