Why there is consumer feedback that the aluminum truss they buy is not durable, the relationship between product quality and good or bad factors are no more than these two points, one is raw materials, the other is the production process, truss production welding process occupies a pivotal role. Welding should grasp the temperature and the position of the weld. So where you can tell if the welding process is good or bad when you buy trusses.
First, observe whether the welding points are uniform and smooth. If there are some metal moles on the truss display, it is likely that in the welding in order to grasp the appropriate temperature, the temperature is too high, resulting in a liquefaction reaction at one end, and therefore deformation.
Secondly, pay attention to observe the position of the weld seams. Each truss display before molding can be said to have experienced a thousand hammering, each weld left welds in addition to distributed at the node, but also in other places, such as the bottom welding in the middle, in order to achieve uniform force, truss is also easy to deform.
