Welding engineers often encounter new materials, structures, or processes.Weldability studies are usually carried out before production to ensure that the new materials, structures or processes used are of high quality.The basic wood is analyzed and tested first, that is, necessary weldability test is done on the basis of weldability theory analysis.Weldability analysis can avoid the blindness of test, and weldability test can verify the results of theoretical analysis.

(1) weldability analysis

Weldability analysis is to use the theoretical knowledge and practical experience of modern welding science and technology to judge or predict the degree of difficulty of metal material welding, estimate the possible technical problems in the welding process, analyze the causes of the problems and find solutions to the problems.Generally, it is analyzed from two aspects of weldability and weldability.The former is to solve the problem of whether the material can be welded or not, and the latter is to solve the problem of whether the material can be used after welding.
