The following are deemed to comply with this requirement: With the exception of quenched and tempered steels, parent materials not identified to a Standard nominated in Item c above may be used, provided one of the following requirements is met: Aids to visual examination may be used wherever necessary to facilitate the assessment of an imperfection. Where the joint contains two welds, the size shall be the combined depths. Typical joint preparations for connections butt-welded from one side are shown in Figure 4.
This is particularly relevant when the direction of loading is normal to selding plate surface Z direction.
Free shrinkage restricted structure e. The transition shall be made by chamfering the thicker part or by sloping the weld surfaces, or by any combination of these as shown in Figure 3. These designations are now consistent for all welding processes for which the harmonized ISO system has been applied.

The size of seal welds shall comply with Clauses 3. Should discontinuities be later detected in the weld heat affected zone it should be remembered that imperfections of parent metal wwelding are not considered a cause for rejection of the weld see Clause 6.
See Appendix D, Item k. 155.41 Appendix Sructures, Items t and u. Under certain circumstances, such as an unusual joint configuration, it may be necessary to prepare two test pieces for different purposes, one as shown in Figure 4. T-joints by other portions of the Medium restraint: Where the weld complies with the relevant test requirements of Clause 4. Single-run and multi-run fillet welds may be qualified on opposite sides of the same test plates.
The probe angle shall be the actual measured angle, not the nominal angle. The test piece may be made as a production test piece. In particular, due consideration shall be given to the control of emitted fumes, especially when welding through paints, primers and other surface coatings.
Statements expressed in mandatory terms in notes to tables and figures are deemed to be requirements of this Standard. Examples include but are not limited to a change from V-shape to U-shape, a change from V-shape to bevel-shape.
Joint details that minimize stress intensity on parent materials subject to stress in weoding through-thickness direction shall be used where practical.

Any segment of intermittent fillet weld shall have an effective length of not less than 40 mm. The holding of one of the following shall be accepted as evidence of these qualifications: Product Availability See publications the same Wslding 2. The specimen shall comply with the requirements of Clauses 5.
Either— i the steel type number, as given in Table 4. See Appendix D, Items tx and y. It is important that readers assure themselves they are using a current Standard, which should include any amendments which may have been published since the Standard was purchased.
Welds nominated as Category SP, but not complying with the requirements of that category, may be considered as Category GP welds, provided the requirements of the design Standard are satisfied and the principal has agreed.

The ends of the slot shall be semicircular or shall have the corners rounded to a or of not less than the thickness of the part containing it, except for those ends that extend to the edge of the part. Where welds fail to meet the criteria of Table 6. Except where a greater hardness is permitted in accordance with Appendix D, Item ithe hardness of weld-heat-affected zones shall be not greater than HV
