Welded steel structure frame/warehouse/workshop/Prefabricated
house/storage/Meatal shed 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
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
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.
