Cases like this are everywhere. The quality of the weld is related to the quality of the engineering structure and directly related to the safety of people's lives and property.

1.First of all, our steel plates are purchased from famous steel plate enterprises。This gives customers the greatest guarantee from raw materials. If there is a problem with the raw material, even if the steel pipe weld is firm, it is useless. So the raw materials of these large factories are the first hurdle we need to control.

2.Secondly, we need to cut the edges of each steel plate. In this way, some rust and pollution on the edges can be removed, and the edges of the plate are neat, which makes it easier to weld the edges when welding.
