The line-up clamp shall be released only after the length of root pass is equal to or greater sa that specified in the qualified welding procedure specification.

PG that occurs in the finish pass shall be unacceptable when any of the following conditions exist: Building Commission Regulates Western Australian building and plumbing industries. The following are represented on Committee ME Weld metal deposit repairs to pipelines made in accordance with Clause The documentation shall include a statement of the qualifications and experience of the welding engineer who will supervise the welds.

AS 2885.2 – Key Concepts and Application

They shall not damage pipe coating both internal and external They shall not contaminate the weld pick up impurities. Care shall be taken to 285.2 that, in addition to the minimum requirements for traverse locations shown in AS They are also similar to the requirements of the superseded editions of this Australian Standard except for wall thicknesses less than 7 mm where limits on embedded defects have been reduced ax 50 mm to 25 mm in length, on the basis of Australian research.


A welding procedure may be qualified by being deemed to be prequalified when the following restrictions are met: Incompletely filled groove and external undercut shall be evaluated by visual examination.

Changes have been made to the application clause to clarify where the Standard is intended to be applied. An example of these special circumstances might be the welding into a pipeline of a large and expensive fitting where it would not be practicable to meet the test weld requirements of this Standard.

These environments may cause stress corrosion cracking SCC of susceptible materials. The outside diameter of the branch pipe shall be not less az one-third of the outside diameter of the pipe run.

The welding procedure used for supervised welds shall be documented and shall be approved. The methods and the requirements for qualifying welding procedures have been clarified. Tack welds shall be deposited only in the weld groove and, where the tack weld is to be incorporated into the finished weld, full fusion at the root shall be obtained.

The test weld shall be examined and tested. Branch weld The welder shall mark out, cut, fit, and weld a reinforced bevelled end sit-on branch to a pipe run. Ads Carousel contents not 2885.2 The regulations were promulgated on 4 July and came into effect on 2 August Where delay in completing some joints is anticipated, the test weld shall simulate that delay. Category 2 partial qualification A welder holding a Category 2 partial qualification may weld only the type or types of weld see Table 4.

ss Cleaning after testing Magnetic particle medium shall be removed after testing. Welds made by GMAW welding should be examined with mechanized ultrasonic testing. This test specimen shall be subjected to the test. Non-destructive examination in accordance with Clause If tack welds are used, they shall be made in accordance with the qualified welding procedure.

Sa standard specifies the minimum requirements for materials, welding consumables, welding processes, weld preparations, qualifications of welding procedures and personnel, and fabrication and inspection requirements for the construction and maintenance welding of carbon and carbon-manganese steel pipelines down to 3.

All welding procedures and welding operations shall be qualified, documented and approved under conditions that simulate those that are expected during field welding.

Butt welds qualified by branch connection weld procedure qualification tests shall be restricted to the types of butt welds involved in the branch connection see also Clause In that event, they shall be considered separate indications.

After any change of components or repair or adjustment of the system. The pipeline shall be earthed prior to the commencement of welding or cutting. The weld between a sit-on branch fitting and a pipe shall be designated a single bevel butt weld.
