1.7 Safety Precautions
This technical document does not address all sclding and health hazards. Hos’eser,pertineni information can be found in the following documents:
1. ANSI Z49. I, Safety in WeldinK cutting. and Allied Processes
2. Manufacturer’s safety literature on equipment and materials
3. Other pertinent documents as appropriate.
These documents shall be referred to and followed as required (also scc Annex D, Safc Practices).
Vote: This code may involve ha:ardou.s ,,wwrials. operations, and equipment. The code does not purport to addrr.cs all cf the safety probkm.c associated with its use. It is the respossshalit’ of the user to establish appropriate safeli and health pructkes. The user should deier,nine the applicability of ant’ regulatory limitations prior to ,rce.
1.8 Standard Units of Measurement
This standard makes use of both U.S. Customary Units and the International System of Units (Sik The measurements may not be exact equivalents; therefore. each system shall he used indcpcndcntly of the other ss ithout combining in any way. The standard with the designation Dl.4:2005 uses U.S. Customary Units. The standard designation Dl.4M:2(X) uses SI Units. The latter are shown s ithin brackets 11.
1.9 Reference I)ocurnents
The followjg standards contain provisions which. through reference in this text. constitute provisions of this AWS standard. For undated references, the latest edition of the referenced standard in use at the date of the contract bid submission shall apply. For dated references. subsequent amendments to, or rev isions f, any of thescjwhlicat ions do not apply.

2.3.2 Flare-Bevel- and Flare-V-Groove Welds. The effective weld area shall be the effective weld length multiplied by the effective weld size (see Figure 2.1). 2.3.2.1 The effective weld length shall be the weld length of the specified weld size. 2.3.2.2 The minimum effective weld length shall not be less than two times the bar diameter for equal size bars or two times the smaller bar diameter for two unequal size bars. 2.3.2.3 The effective weld size, when filled flush to the solid section of the reinforcing steel bar, shall be 0.4 of the bar radius for flare-bevel-groove welds and 0.6 of the bar radius for flare-V-groove welds. Larger effective weld sizes may be used to determine allowable stresses provided, the WPS qualifies the larger weld size. When bars of unequal diameter are being joined, the effective weld size shall be based on the radius of the smaller bar. See 6.2.6.2 for macroetch test requirements for determin- ing weld size. 2.3.3 Fillet Welds. The effective weld area shall be the effective weld length mutiplied by the effective throat. (Stress in a illt weld shall be considered as applied to this effective weld area, for any direction of applied load.) 2.3.3.1 The effective weld length of a curved fillet weld shall be measured along the weld axis. 2.3.3.2 The effective throat shall be calculated as the minimum distance from the weld root to the face of the fillet weld, minus convexity.AWS D1.4/D1.4 M pdf download.
