Destructive Welding Testing Methods

When NDT (Non-Destructive Testing) procedures don’t measure up, then weld inspectors opt for destructive weld testing methods. As the label implies, small samples of the subject weld are exposed to destructive energies. That’s not a task that can be addressed with a carefree demeanour. Unlike a radiographic test, this procedure affects weld zones, so these […]

Differences between Radiographic and Ultrasonic Testing of Welds

Radiographic and ultrasonic weld testing, industry-standard inspection solutions for sure, are both held in high regard. They’re industry standards, seeing deeply inside opaque fuse zones with specially designed sensory mechanisms. Two different technologies dominate their operational architectures, but they both capture similar datasets, which are then rendered on a screen of some sort. Focusing on […]

Welding Inspection Standards and the Importance of High Quality Output

To safeguard welding inspection standards, it’s important to have a best-in-class inspection program in place. The weld examiners use especially determined engineering codes and standards to assess fuse-bonded discontinuities and to gauge whether these flaws exceed certain in-service requirements and/or fabrication criteria. Ultimately, the journeymen in this tough-as-nails industry must deliver high-quality output, not just […]

Keys to Quality Precision Welding

Weld torch travel speed is constant, yet there are weld line inconsistencies occurring every few centimetres. The contact to work distance is just-so, yet the melt pool is spitting explosively. Cracks, pinholes, and more, a formerly predictable workflow is suffering from strange, unpredictable material fusing issues. Even if the welder has a reputation for applying […]

Hardness Testing in Welded Materials

Welded materials are put under extraordinary stress. So far, the cooled fusing zone and depth of the weld are satisfactory, as is the shape and texture of the material. It’s even optimized been so that a perfectly profiled joint is anchoring two parts together. Everything looks good, but, as any engineer knows full well, looks […]

Test Parameters for Weld Procedure Qualification

Like a mechanically-slanted skills portfolio, engineering services use weld procedure qualifications to provide proof of designated jointing techniques. Instead of print and photographs, however, the procedures are carried out on a qualification plate. After all, the managers who are developing an expensive structural investment aren’t about to take the word of a welding company, even […]

MIG and TIG Welding: What are the Differences?

Clear distinctions separate MIG and TIG welding techniques. MIG (Metal Inert Gas) welding can be recognized by an industry insider just by viewing the operation. Standing nearby, wearing tinted welding goggles, of course, a wire electrode is being fed continuously towards the weld pool by the expert technician. TIG (Tungsten Inert Gas) welding technology approaches […]
