Understanding Weld Discontinuities and Its Causes
Blog | December 6th, 2018It’s all very well having a welding inspector’s report in hand. The papers are typed, and they’ve been delivered to multiple engineering departments. It’s the contents that are alarming, though. There are weld discontinuities noted in the report, plus a series of appended photographs. They frame the trouble spots. To beat the problem, to execute […]
Welding Imperfection and Cavities: Causes and Prevention
Blog | November 23rd, 2018Inferior welds don’t just look bad, they deliver poor structural performance, too. The shoddy work won’t pass muster as a mechanically sound metal joint. There are weld imperfections in the seam, which have been visually or instrumentally detected. Cavities are undermining the joint, so it cannot deliver material integrity. If we’re to stop such process […]
Weld Coating Inspection and Why Non-Destructive Testing is Needed
Blog | November 16th, 2018A weld coating inspection can’t just cut out a section of the coating, then dispatch it to a lab for testing. That’s an approach that would defeat the whole purpose of the weld overlay, after all. No, a non-destructive test and inspection system should be recruited here, with its wet comb filters and wheels leading […]
Destructive Welding Testing Methods
Blog | October 24th, 2018When 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
Blog | October 12th, 2018Radiographic 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
Blog | September 27th, 2018To 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 […]
Reliable Welding Inspection for Welded Structures in Mining Equipment
Blog | September 14th, 2018It’s hard to imagine a more abrasive environment. Grizzly screening bars and primary feeder chutes are experiencing a high-volume load as it exits a bank of mining equipment. The rocks are coarse, incredibly rough-edged, and they’re subjecting the alloy-reinforced equipment to almost unendurable levels of mechanical force. Fasteners are destroyed in a few short days […]
Keys to Quality Precision Welding
Blog | August 27th, 2018Weld 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
Blog | August 17th, 2018Welded 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
Blog | July 27th, 2018Like 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 […]
