4.焊合流畅的筹算

4.1 Scope

4.1边界

This clause covers requirements for design of welded connections. It is divided into three parts as follows.本章包括焊合流畅筹算的要求。它分为以下3部分:

Part A-Common Requirements for Design of Welded Connections (Nontubular and Tubular Members)

A部分-焊合流畅筹算的通用要求(非管材和管材部件)。

Part B-Specific Requirements for Design of Nontubular Connections (Statically or Cyclically Loaded). The requirements shall apply in addition to the requirements of Part A

B部分一非管材流畅筹算的特定要求(静荷载或周期荷载)，这部分要求应另加A部分要求使用。

Part C-Specific Requirements for Design of Nontubular Connections (Cyclically Loaded). When applicable, the requirements shallapply in addition to the requirements of Parts A and B

C部分一非管材流畅筹算的特定要求(周期荷载)，当适用时，这部分要求应另加A部分和B部分要求使用。

Part A A部分 Common Requirements for Design of Welded Connections (Nontubular and Tubular Members) 焊合流畅筹算的通用要求（非管材和管材部件）

4.2 General

4.2抽象

This part contains requirements applicable to the design of all welded connections of nontubular and tubular structures, independent of loading.

本部分包括适用于非管材和管材结构系数焊合流畅的筹算要求，而与荷载形式无关

4.3 Contract Plans and Specifications

4.3条约图纸和本事条目

4.3.2 Notch Toughness Requirements. lf notch toughnes of welded joints is required, the Engineer shall specify the minimum absorbed energywith the corresponding test temperaturefor the filler metal classification to be used, or the Engineer shall specify that the WPSs be qualified with CVN tests. If WpSs with CVN tests are required, the Eingineer shall specify the minimum absorbed energy the test temperature and whether the required CVN test performance is to be in the weld metal. or both in the weld metal and the HAZ(see 6.2.1.3 and Clause 6. Part D).

4.3.2缺口韧性要求,淌若要求焊合磋议缺口韧性，工程师应按所用的填充金属等第划定相应磨砺温度的最低领受能量，约略

工程师必须划定评定的WPS带有CVN磨砺。淌若要求WPS带有CVN磨砺，则工程师必须划定最低领受能量，磨砺温度以及所要求的CVN磨砺究竟是在焊缝金属中，一经焊缝金属中庸HAZ中两者齐要(见6.2.1.3和第6章，D部分)。

4.3.3 Specifie Welding Requirements. The Engineer, in the Contractdocuments, and the Contractor, in the shop drawings, shall indicate those joints or groups of joints in which the Enginer or Contractor require a specific assembly order, welding sequence welding technique or other special precautions, See 7.4.1 and C-7.4.1 for limitations on the application of ESW and EGW welding4.3.3特定的焊合要求,工程师在条约文献中,而承包商则在工场图纸中,应表明他们对哪些磋议或磋议组要求特定的安装门径焊合礼貌，焊合本事或其他尽头的扫视事项。ESW和EGW焊合诈欺的达概念7.4.1和C-7.4.1。

4.3.4 Weld Size and Length, Contract design drawings shall specify the effective weld length and, for PIP groove welds, the required weld size “'(S),." For fillet welds and skewed 'T-joints, the following shall be provided on the contract documents.

4.3.4焊缝尺寸和长度,条约筹算图应划定灵验的焊缝长度，以及PP(磋议部分熔透)坡口焊缝的焊缝尺寸“(S)”。对于角焊缝和斜T形磋议，应在条约文献上划定下述实质:
