The welds may be produced by position or roll welding or by a combination of position and roll welding. The welding may be done by a shielded metal-arc welding, submerged arc welding, gas tungsten-arc welding, gas metal-arc welding, flux-cored arc welding, plasma arc welding, oxyacetylene welding, or flash butt welding process or by a combination of these processes using a manual, semi- automatic, mechanized, or automatic welding technique or a combination of these techniques.

It applies to both new construction and in-service welding. This standard covers the gas and arc welding of butt, fillet, and socket welds in carbon and low-alloy steel piping used in the compression, pumping, and transmission of crude petro- leum, petroleum products, fuel gases, carbon dioxide, nitro- gen and, where applicable, covers welding on distribution systems. Once you have calibrated your screen with your first probe for all renaming angle probes you'll just need to marginally adjust your delay to compensate for differing bean paths with differing angles in the wedges.API STD 1104 pdf download.Welding of Pipelines and Related Facilities You'll need to do this fro each probe you plan on using eg 45, 60 annd 70 degrees. If this is accurate you'll have successfully calibrated your screen / probe combination for 0 to 100mm. To calibrate shear wave probes you'll need two simultaneous reflectors at known (differing) beam paths, for example use the 25 and 50mm radii of the V2 kidney block to set echoes from 25 mm and 100mm, then reverse the probe, aim at the 50mm radius and check the response is at 50mm.

Generally FBHs are used for sensitivity setting (eg DAC) which requires a minimum of 3 points (reflectors) to create a curve, less and its a straight line! Or more likely he is not a UT Level 3įirst dont get calibration and sensitivity confused. No practical element in the ASNT Level III exam might go some (but not all) the way to explain James' predicament. Re: API 1104 Manual UT In Reply to Dent at 16:13 May-02-2014.
