Welding technology is a traditional subject

but with the rapid and comprehensive development of science and technology

welding technology will be given new connotation and extensive extension. Combining with the development history and research status of welding technology

this paper combs the basic problems and realization goals of welding science

welding technology and welding engineering

as well as the close relationship between the development of the three; discusses the thinking of scientific discovery of welding

innovative ideas of welding technology

and the creation method of welding process. Combined with the factors of welding material

process and structure

the innovative ideas and methods of "from 1 + 1 to calculus" are put forward. From the content

interest

motive force and purpose of welding innovation

this paper describes the supporting role of mathematics

physics and chemistry theory on welding science and engineering innovation and creation

and describes the thinking and ways of welding innovation creation from the concept of multi-dimensional and multi-scale material connection space

and further shows that welding discipline is an interdisciplinary

open sharing and innovative discipline system.
