Weld penetration test

However, the scope to identify specific joints for inspection would allow the project specification to test, for example, samples from "run-off" plates attached to in-line butt welds. A definite procedure for the testing of welds is not set up as a part of the normal routine of ordnance units operating under field conditions. The width of the specimen is measured in inches. Once the welds were in place, the engineer had them UT'd. At that rate, most would require testing of all welds in question. That standard prescribes tests to qualify welders based upon process, consumable, type of joint, welding position and material.

Your workflow and productivity are greatly improved. These globs of metal are referred to as icicles. In S , steels full strength is also developed in fillet welds and partial penetration welds with overlying fillets provided that such welds are symmetrical, made with the correct consumables and the sum of the weld throats is equal to the thickness of the element that the welds join. This is a test or inspection method used on welds and parts made of magnetic alloy steels. These methods determine a level of preheating to modify cooling rates, which allows time for the hydrogen to migrate to the surface and escape particularly if maintained as a post heat on completion of the joint instead of becoming trapped in the hard, stressed zones. Studs are loaded into the gun and on making electrical contact with the work, the tipped end arcs and melts.

For applications where a greater sensitivity to smaller defects is required, the fluorescent penetrant method is preferred. Preheating also lessens thermal shock. The weld pool is submerged by flux fed from a hopper. MIG Metal Inert Gas welding is the most widely used and perhaps the most easily mastered type of welding for industry and home use. Pre-production testing is used to prove the welding procedure and, depending on the application, includes bend tests, tensile tests, torque tests, macro examination and radiographic examination. Additionally, production tests may be specified on:

The quality of the weld metal at the face and root of the welded joint, as well as the degree of penetration and fusion to the base metal, are determined by means of guided bend tests. A wet or dry type developer is then applied. The developer assists to draw penetrant out from the surface breaking discontinuities. The specimens tested are required to bend 90 degrees without breaking apart. This is a nondestructive test used to check the quality of welds on closed containers such as pressure vessels and tanks.
