steel frame/steel plate
We use Ultrasonic detector ,X-ray detector , Paint film thickness gauge to check .
Top quality steel structure workshop 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.
