Why Is Carbon Dioxide Shielded Welding Used for Crane Spreader Welding?

The welding technology of crane spreader includes several aspects such as welding materials, base metal treatment, weldment inspection, welding personnel management, etc. Carbon dioxide gas shielded welding is usually used for crane spreader welding. The following are the advantages of carbon dioxide shielded welding:

1. The relative density of the current is high, the heat of the arc is relatively concentrated, the melting of the welding wire is relatively sufficient, it is easy to penetrate the base metal, the welding thickness is increased, the professional technical level of the welding personnel is low, the speed is fast, and the work efficiency is relatively high.

2. The price of welding materials for carbon dioxide shielded welding is relatively low, the operation is simple, it is suitable for various operating environments, and it is widely used.

3. The welding stress and deformation are small, which can better control the generation of cold cracks.

4. The arc is well visible, and it is easy to realize multi-angle welding.

The technical performance of the container spreader has been improved through the research and years of operation experience of Henan flag crane Co., ltd technicians. Flagcrane provides standard and non-standard cranes and spreaders that have passed third-party certification. Welcome to flagcrane's factory visit.
