Precautions and operation points

1. Preheating and inter-channel temperature are required to be controlled between 135-165℃.

2. The welding process should strictly control the welding line energy, and it is recommended to use small line energy to achieve the purpose of refining the grain and improving the performance, otherwise it is easy to make the welded joint coarse grain and deteriorate the mechanical properties of the welded joint.

3. The above welding methods, conditions and specifications are for reference only, and users should evaluate the process according to their own characteristics before using the product
