Welded steel frame

Used portal frame structrual steel modern workshop modular house must have strict process and good qulity , than it is safe and long life .

1. Strictly control the welding position of the relative position of size , welding pass behind the prospective;

2. Reasonablly selection of welding parameters and order to prevent crack;

3. Electrode required drying, welding area need to clean up, welding process, together with the appropriate welding current, decrease of welding speed, gas completely escape , prevent the formation of weld porosity;

4. When continuously multi-layer welding, each weld layer after cleaning, prevent the formation of slag;

5. Selection for current, avoid arc pull too long, control electrode angle and arc method, avoid the generation of undercut.

Attached: welding process parameters

welding process parameters

Materals(mm)	Electrode diameter (mm)	Welding current(A)	Welding voltage(V)	Welding speed(m/min)
<10	Ø3.2	200-250	30-38	0.2-0.3
10-20	Ø4.0	200-250	30-38	0.15-0.25

Installation Notice

1.Steel structure welding requirements

Engaged in welding of steel structure work welders must pass the examination and obtain a certificate. The holder welder must welding in its passing the examination and approval within the scope of the project.

2.Fastener connection requirements

Steel structure fabrication and installation of units should be in accordance with the provisions of the high strength bolts respectively connected with friction surface of the anti slip coefficient test and retest, component friction surface site should be dealt with separately anti slip coefficient test, the results should be consistent with design requirements.

3.Steel structure assembly and installation of steel structure requirements

(1) of H type steel welding seam splicing spacing and the web of the seam shall not be less than 200 mm.

(2) and crane beam crane truss installation in place should not be deflection.

(3) multi section column installation, each column positioning ground control axis should lead directly, not from the axis of lower column guide, avoid too large error accumulation.

(4) the steel grid structure after the completion of the total spell and roofing project should be finished respectively to measure the deflection, the deflection and the measured value of 1.15 times can't exceed the design value.

(5) coating, coating times, coating thickness shall comply with the design requirements.

(6) the thickness of coating coated thin type fireproof coating shall conform to the requirements of design about the fireproof limit.
