3 Classification principles
Welding terminology
Metal welding and brazing The representation code of the welding method on the diagram. General principles for classification and coding of mechanical manufacturing process methods. 3.1 Division of large and medium categories | Division
3.2.1 Arc welding subcategories are divided according to welding conditions. 3.2.2 Resistance welding subcategories are divided according to welding methods. 3.2.3 The gas welding subcategory is mainly divided according to the category of combustion-supporting gas. 3.2.4 The pressure welding subcategory is mainly divided according to the energy form. 3.2.5 The brazing subcategory is mainly divided into the brazing filler metal category. 3.3 Division of subdivisions
3.3 .1 Each subcategory of electric welding is subdivided according to their respective process characteristics. Gas welding is subdivided according to the type of combustion gas, and 3.3.2
3.3.3 brazing is subdivided according to welding conditions and heating methods. The division and codes of sub-categories of welding process methods 4
The division and codes of sub-categories of welding process methods are as specified in Table 1, 5 The division and codes of sub-categories of welding process methods The division and codes of sub-categories of welding process methods are as follows The provisions of Table 2.
