Welding Inspection Services: What is it all about?

20 July 2017

Consider the importance of a welded joint for a moment. Here’s an engineering technique that resolutely fuses two or more metal workpieces together. A robust weld is strong and reliable, but what if that fused metal join isn’t executed correctly, as specified by a nationally accredited set of engineering codes? In this case, the quality of the parts union can’t be assured. Welding inspection services exist to prevent this dangerous scenario.

Visual Welding Inspections 

The seasoned eye of a trained welding inspector scans all of the heat-generated joints. The program evaluates the quality of every fused connection and relates the integrity of the union to the application. Essentially, the metal working procedure must be conducted properly, must be applied in compliance with all engineering statutes, but it also must be suited for the structure at hand. That’s a challenging exercise to master, but it’s one that an inspector is expected to administer with great diligence. This competent individual visually evaluates the work for material discontinuities, fractures, overlaps, and other operation errors. On this occasion, it’s a Non-Destructive Test (NDT) strategy that inspects the post-processed welds.

Comprehensive Project Evaluations 

In the above example, the work is inspected after the welding procedures have concluded. This is a passive but highly effective strategy. Still, a more dynamic approach yields superior results. For example, if the welding inspection service incorporates a pre-check stage, then corrective measures can be taken before the work commences. This dynamic approach inspects the fabricated structure, the welding equipment, and the joint surfaces before a single lick of work is done. Resources are saved in this manner because the inspection finds the work errors and fabrication configuration problems before the welding procedure begins.

Welding Inspection Services: Technological Solutions 

A visual inspection, when managed by an expert inspector, emulates an effective quality control program. Arguably, however, this approach can only see so far. If we’re to go deeper, we need to call in an array of sophisticated tools and instruments. Ultrasonic weld inspection instruments and radiographic devices represent the higher end of the inspection spectrum here, with their electronic sensors detecting hidden flaws in the internal structures of the weld. Designed to nondestructively probe a welded join, the technology captures an X-Ray like view that penetrates deep inside the solidified filler and cooled metal so that fastening integrity can be properly evaluated.

All of these welding inspection services have their parts to play. They visually evaluate discontinuities, dimensional errors, and generally substandard join practices. Available for every stage of the project, from the initial fabrication work to the in-action welding work, plus the essential post-inspection stage, the program is responsible for ensuring joint anchoring quality. In other words, a correctly coordinated welding inspection strategy plays a massive role in guaranteeing overall structural fastening integrity.
