One of the decisive factor of the truss quality is the welding technique. If you would like to choose truss at acceptable quality, you should check the point of weld first. You can see if the weld joint is orderly and evenly distributed.
Second, it is also important to observe the position of the weld joint. Generally, you can find that you can see uneven weld joint on triangle truss or multiangular truss.
The truss hardness level is also a key factor of the truss quality. It guarantees the stage safety. The truss may become deformed if it is not hard enough so that it may cause a potential safety hazard.
