The welding test plate has the following functions:

1, the welding test plate is used to determine the feasibility of the selected welding method;

2. The welding test plate is used to evaluate the performance of welded joints;

3, according to the material and thickness of the welding test plate, select the welding specification parameters;

4. Preheating and post-weld heat treatment of welding test plate are the basis of welding procedure qualification.

In addition, the inspection results of the welded plate only represent the products welded with the specimen, mainly because the welding quality is not only related to the process, but also to the welder, environment, welding materials and many other factors.
