Attention should be paid to the process points when gas cutting of steel structure
1. Before gas cutting, it is necessary to check to confirm that the equipment and tools of the entire gas cutting system are in normal operation and ensure safety; 2. Correct process parameters should be selected during gas cutting. When cutting, the shape of the oxygen jet should be adjusted to achieve and maintain a clear outline, long wind line and high shooting force; 3. Before gas cutting, the dirt, oil, rust and other debris on the surface of the steel should be removed, and the bottom Leave a certain space to facilitate the blowing of slag; 4. During gas cutting, tempering must be prevented; 5. In order to prevent gas cutting deformation, the operation should be carried out from the short side; first cut small pieces, then large ones; cut complex ones first , after the cut is simple.
