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.

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

1.Dimension :Length , width, height, eave height , roof pitch .

2.Doors and windows :dimension , quantity , where to put them.

3.Local climate : Wind speed , snow load ,etc

4.insulation material :sandwich panel or steel sheet

5.Crane beam :Do you need crane beam &tons? inside the steel structure or outside ?

6.Is there any materials that are not allowed to imported into the country where the structure is planning to use ?

7.What is the founctions of the workshop? we must consider the wind and lighting inside.
