Applicable Regulatory Agencies
Work performed in accordance with this standard may involve the use of materials that have been deemed hazardous, and may involve operations or equipment that may cause injury or death. This standard does not purport to address all safety and health risks that may be encountered. The user of this standard should establish an appropriate safety program to address such risks as well as to meet applicable regulatory requirements. ANSI Z49. I should be considered when developing a safety program.
1.7 Units of Measurement
This standard makes use of both U.S. Customary Units (US) and the International System of Units (SI). The latter are shown within brackets ([1) or in appropriate columns in tables and figures. The measurements may not be exact equivalents; therefore, each system must be used independently.
1.8 Normative References
The standards listed below contain provisions, which. through reference in this text, constitute mandatory provisions of this cxlc. For undated references, the latest edition of the referenced standard shall apply. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply.

2.4.2.2 PIP Groove Welds. The size of a PiP groove weld made with GMAW or GTAW regardless of the position of welding is the depth of preparation for V- and bevel-joints with an included angle greater than 45° and all U- and i-joints.
2.4.3 Effectie Area. The effective area is the effective weld length multiplied by the weld size.
2.4.4 CJP. The following types of welds are CJP groove weld s:
(1) Groove welds welded from both sides with the root of the first weld backgouged to sound metal before welding the second side.
(2) Groove welds welded from one side using permanent or temporary backing.
(3) Groove welds without backing with root passes made from one side using GTAW (AC or DCEN).
(4) Groove welds welded from one side using PAW- VP in the keyhole mode.
Recommended details of CJP groove welds in butt, corner, and T-joints arc given in Annex B I.
2.4.5 PJP. Groove welds without backing welded from one side and groove welds welded from both sides hut without hackgouging are PiP groove welds, except as noted in 2.4.4.
Recommended details of PiP groove welds for butt, corner, and T-joints are given in Annex B2.
2.5 Fillet Welds
2.5.1 Effective Throat. The effective throat is the shortest distance from the joint root to the face of the diagrammatic weld.
2.5.2 Length
2.5.2.1 Effective Length (Straight). The effective length of a straight fillet weld is the overall length of the full-size fillet, including boxing. No reduction in effective length shall be required for the start or stop crater of the weld.
2.5.2.2 Effective length (Curved). The effective length of a curved fillet is measured along the centerline of the effective throat. lithe weld area of a tillet weld in a hole or slot calculated from this length is greater than the area calculated from 2.6.1, then this latter area shall be used as the effective area of the fillet.AWS D1.2-D1.2M pdf download.
