Abstract:
Butt-fusion welding is the main technology to join high-density polyethylene (HDPE) plastic pipes, which are widely used in transport the water, gas and corrosive liquid. Investigation shows that one of the failure modes of HDPE pipe is the crack slowly grows across the thick direction and leads to failure at last, so that it is very important to study the resistance to crack initiation of HDPE pipe and its butt-fusion welded joint. In this study, the elastic-plastic fracture mechanics parameter, crack opening displacement (COD) is used to describe the fracture initiation behaviors for the HDP

The paper concerns numerical analysis of thermal phenomena occurring in the butt welding of two different materials by a laser beam welding. The temperature distribution for the welded butt-joint is obtained on the basis of numerical simulations performed in the ABAQUS program. Numerical analysis takes into account the thermophysical properties of welded plate made of two different materials. Temperature distribution in analysed joints is obtained on the basis of numerical simulation in Abaqus/Standard solver, which allowed the determination of the geometry of laser welded butt-joint.

Under-matched welds could minimize the tendency of cold cracking and reduce the preheating operations when high strength steels are welded.

From the point of view of fatigue and stress corrosion cracking, the weld residual stress perpendicular to the weld axis is of particular interest.

Stationary shoulder friction stir welding (SSFSW) is a recently developed variant of conventional friction stir welding (FSW). Recent studies have shown that SSFSW can join high strength aluminum alloys with improved mechanical strength and reduced distortion as a result of a narrower and more uniform thermal profile. However, a lack of understanding on the residual stress development in the SSFSW process makes it difficult to assess the structural integrity and delays a widespread application of this technique to industry.

Abstract:
To investigate the influence of hydrogen on the tensile and fatigue life properties of welded joints of 304/308 austenitic stainless steels, slow strain rate tensile (SSRT) tests and fatigue life tests were conducted in laboratory air using hydrogen exposed specimens. The specimens were fabricated from welded plates, and to elucidate the role of weld structure on hydrogen-induced degradation, the welded joint was solution-treated. In the SSRT tests of the as-welded (AW) joint, a non-exposed specimen failed at the base metal (BM), whereas a hydrogen-exposed specimen failed near the weld toe. In

Abstract:
The objective of this study is to establish the fracture assessment method for nuclear power components made of Ni-based alloy weld metal. Fracture tests of butt welded plates of alloys 182 and 82 with a surface flaw were conducted in tension at 300°C. The dimensions and shapes of weld groove of the test plates were intended to simulate the weld joint of BWR shroud support. Semi-elliptical surface flaws were introduced by EDM. Fatigue pre-crack was introduced from an EDM notch for one test plate of alloy 182 to investigate the effect of crack tip shape on the fracture. It was found that the fr

Abstract:
Demonstrating the reliability of existing pipelines under new loading conditions requires the use of standard methods that have known applicability to that type of pipe and data relevant to the pipe.� Both of these may be lacking for early generation pipelines, such as ones from the 1930s and 1940s, where the girth welds can have been welded with processes not commonly used today (oxyacetylene welding) or with joint designs that use internal backing.� Three types of joint designs were particularly used in this study:� butt joints with an internal backing ring, butt joints with a backing or chi

Abstract:
The inspection of welds made onto in-service pipelines, which are made primarily for attaching branch connections and repair sleeves, has been the subject of much concern in recent years. The difficulties associated with the inspection of these welds have long been recognized and, historically, the amount of inspection given to such welds has been small. The inspection of welds joining various appurtenances to pipelines is hampered for a number of reasons. The joint geometries can vary considerably, but none of them are particularly suited to detailed inspection. Surface techniques, such as ma

Abstract:
Inspection of pipeline field girth welds during pipeline construction is accomplished by film radiographic: methods. Film radiography of materials is a 70 year old technology. There have been many advances in that 70 year history in equipment and films, but the process of making the radiograph is essentially the same. The film radiography process is time-consuming, costly, environmentally impacting and very operator (inspector) dependent. There are recent and almost daily advances in technologies using x-ray imaging other than film. Double-jointed pipe welds at pipe mills and at double-joint o

Abstract:
Over many decades it has been accepted that the most economical way to produce a pipeline is to join together the standard lengths of pipe as quickly as possible, using a highly mobile task force of welders and other technicians, leaving tie-ins, crossings, etc. to smaller specialist crews. The work pattern which evolved almost invariably involved several crews of welders strung out along the pipelines, progress being controlled by the rate at which the leading pair could complete the weld root. The spread from this first crew to final inspection could be a considerable distance, acceptable on

Abstract:
The British Standards Institute document PD6493:1980 uses the crack tip opening displacement (CTOD) design curve as a method for determining defect acceptance levels in welded joints. The document is under revision and current proposals for the fracture section of the revised document employ three levels of assessment procedures, arranged as a progression from simple stress treatments producing conservative results, to critical analyses which incorporate more rigorous stress analyses and contain no inherent factors of safety. The proposed Level 1 assessment procedure is generally consistent wi
