How does the steel structure ensure no deformation during the welding process?

During the installation and construction of the steel structure in Foshan, the improper use of welding or the wrong method can directly affect the installation of the whole steel structure, the steel structure and its whole function. So welding is very important in the construction process, so how to control the deformation of the welding? The methods are:
1. try to use smaller groove sizes to reduce the overall welding area.
2. try not to preheat. If you do not want to warm up, you should reduce the preheating temperature. In the welding process, you should choose a smaller heat input method.
3. try to use multi-layer welding instead of single layer welding.
4. double sided welding should adopt double-sided symmetrical groove, multilayer welding is to adopt symmetrical welding sequence.
5. discontinuous soldering can be achieved under various conditions.
6. rigid fixture fixed method
Foshan steel structure suggests that the welding of steel structures should be carried out by professional staff. This effect is quick and the quality is good.
