This part replaces YC/T 10.3-2006 "General Technical Conditions for Tobacco Machinery Part 3. Welded Parts", and YC/T 10.3-Compared with 2006, the main technical changes except editorial changes are as follows.

--- Unspecified dimensional tolerances directly refer to national standards (see 3.4.1.5, 3.5.6, 2006 editions 3.4.1.3, 3.5.6);

--- Removed the requirements for welding personnel (see 2006 edition 3.1.7);

--- Increased the general requirements for the welding of stainless steel sheet metal parts (see 3.1.8~3.1.10, Table 1);

---Modified the requirements of the welding process (see 3.3.1, 2006 version 3.3.1);

--- Revised the thickness requirements of the flame cutting board (see Table 2, Table 1 of the 2006 edition);

--- Increased dimensional deviation requirements for water cutting and cutting (see Table 4);

--- Increased dimensional deviation requirements for laser cutting blanks (see 3.4.1.4);

--- Modified the angular limit deviation requirements of the splicing piece (see 3.5.6, 2006 version 3.5.6);

--- Modified the dimensional deviation requirements of welded parts (see Table 7, Table 5 of the 2006 version);

---Modified the general tolerance requirements for the flatness, straightness and parallelism of welded parts (see Table 8, Table 6 of the 2006 edition);

--- Modified the angular deviation requirements of the welded parts (see Table 9, Table 7 of the 2006 version);

--- Increased the quality requirements for stainless steel fusion welding (see 3.6.2.6, 3.6.2.7, 3.6.2.9);

--- Increased welding requirements for stainless steel sheet metal parts (see 3.6.2.8);

--- Increased the quality requirements for stainless steel resistance welding (see 3.6.3.5);

--- Increased the requirements of the leak test (see 4.4);

--- Increased the requirements for stainless steel welding quality inspection rules (see 5.6).

This part is proposed by the National Tobacco Monopoly Bureau.

This part is under the jurisdiction of the National Tobacco Standardization Technical Committee Smoke Machine Subcommittee (SAC/TC144/SC3).
