16、-2:2000 1 Scope The purpose of this European Standard is to exemplify sound and accepted welded connections applicable to welded, not intemal, pressurized steel components. It does not promote the standardization of connections that may be regarded as mandatory or restrict development in any way. Th

17、e requirements of carrying capacity, fitness for purposes, fatigue and corrosion stress are to be considered if necessary. This standard contains examples of connections welded by the following processes (process numbers according to EN IS0 4063): - Manual metal arc welding (1 11); - Self-shielded t

18、ubular-cored arc welding (1 14); - Submerged arc welding (12); - MIG welding; Metal inert gas welding (131); - MAG welding; Metal active gas welding (1 35); -Tubular cored metal arc welding with active gas shield (136); -Tubular cored metal arc welding with inert gas shield (137); -TIG welding; Tung

19、sten inert gas arc welding (141). Other processes by agreement. Further requirements should be considered in accordance with existing application standards. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative r

20、eferences are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references

In cases where full penetration butt joints are indicated, it

28、is intended that they shall be back chipped or gouged and back welded, or alternatively that the welding procedure shall be such as to ensure sound and effective root penetration. 3.2.3 Butt joints with significant difference of thickness Depending on the type of load (type of action effect) and the

29、 difference of thickness, adjustment with the weld or bevelling is necessary (see Table 1 and Figure 1) when the direction of strength is perpendicular to the weld.
