First, the preparation of welding instructions welding instructions welding process is the basis for assessment and evaluation of the original object, the welding process should be assessing the content of all reflected. Include: the natural conditions of welded joints, base material type, welding method, welding material, welding current, welding voltage, welding speed, preheat temperature. Welding instruction is usually recommended in the standard format, you can also design their own format.

Second, the provisions of the standard welding conditions for specimen preparation; by the unit of skilled welding personnel using welding electrode  welding of the unit sample; used in welding conditions should strictly abide by the welding process instructions;

Third, the physical and chemical experimental pilot projects identified in accordance with the relevant standards; preparation of various properties in accordance with the standard sample; in accordance with the standards of a variety of performance tests; fill in test reports of each pilot project.

Fourth, the preparation of welding procedure qualification welding consumable  qualification report on the welding procedure qualification report is a comprehensive summary of tests, so the test results should be summarized, and gives the final conclusion. Welding procedure qualification reports of the role: as a basis for development of welding procedures, with guidance. Welding procedure qualification report is usually recommended in a standard format.
