Why do consumers report that the truss stage aluminum they bought is not durable, and the factors that affect the quality of the product are nothing more than these two points: one is the raw material, the other is the production process, and the welding process of truss production plays an important role. Welding must grasp the temperature and the location of the weld. So when buying a truss, you can judge the quality of the welding process from where.
First, observe whether the welding point is uniform and smooth. If there are some metal bumps on the truss stage aluminum, it is probably because the temperature is too high during welding to cause a liquefaction reaction at one end and therefore deformation.
Secondly, pay attention to observe the welding seam position. Before each truss is formed, it can be said that it has undergone a lot of hard work. The welds left in each welding are distributed at the nodes, but also in other places, such as the middle of the bottom welding.
