In cases when strong weld is needed, groove weld
might be applied.
Productivity and quality benefits are found in applications such as narrow groove welds
, pipe welds, clad overlay, square butt joints, high-speed fillet welds, hard banding, and others.
It covers all forms of welded joint, including butt or groove welds
, fillets, lap, edge and tee joints, corners and cruciform, both plate-to-plate and tube-to-tube in similar or dissimilar materials, which are produced using all manual and automated welding methods, from stick and oxy-acetylene techniques, to TIG, MIG, MAG and plasma arc, even brazing and soldering.
The use of AUT has primarily been driven by the need to identify critical lack of fusion flaws in narrow gap shallow angle groove welds
, difficult to detect with radiographic (RT) methods.
Among the topics are measuring residual stresses in surface treated stainless steel groove welds
, evaluating arc evaporated coatings on rounded surfaces and sharp edged, residual stresses in dissimilar weld joints, the experimental analysis of shot peening on carburized for carbonitrided parts, measuring stress in aluminum using a Gobel mirror as the primary beam optics for an X-ray diffractometer, the thermal fatigue study of hardfaced hot forging tools using numerical analysis and residual stress evaluation, and investigating residual stress distribution in wheel rims using neutron diffraction.
The groove welds
were laid according to AWS A5.23-90 and welding parameters were maintained as shown in Table 1 using DCEP polarity.
No, it's got nothing to do with live loads or dead loads, plug welds or groove welds
, moments, beams, stair stringers, or vaults.
* Used fillet welds in preference to groove welds
, provided the size is not too large.
For vision seam tracking for scanning the joint while welding to keep the welding torch and seam aligned and vary welding parameters to assure a uniform fill on varying groove welds
* Servo Robot Laser vision seam tracking for scanning the joint while welding to keep the welding torch and seam aligned and vary welding parameters to ensure a uniform fill on varying groove welds
(i.e., cast parts);
