Welding procedures are usually developed in accordance with a welding code or standard that requires weld samples be produced, inspected, and tested to establish qualification. Laboratory Testing is a full-service material testing provider with complete in-house resources to turn your order around quickly and reliably.
LTI performs destructive and non-destructive weld testing to verify that a welding procedure and welds produced according to the procedure meet requirements. Welding coupons and specimens are also prepared onsite in our machine shop. The results of all qualification testing are documented in certified reports.

Welding Procedure Qualification The welding procedure is reviewed in detail, then testing and inspection is performed on welds produced in accordance with the procedure to verify all requirements are met. Weld coupon testing often includes visual examination, mechanical testing, metallographic examination and nondestructive testing.
LTI may also assist with preparation of Welding Procedure Qualification as per client or project requirements. Welder Qualification After confirmation that a welding procedure meets a specified standard, welders may be qualified for the procedure.

The welder qualification test is generally required to support welder certification. Contact LTI to discuss your requirements for welding procedure qualification or welder qualification services. Examination for characteristics such as weld size, fusion, penetration, profile, and weld discontinuities is performed at magnifications anywhere between 1X and 50X.
The weld test for hardness evaluates the strength of the weld and is performed on a ground and etched sample, similar to the macroetch specimen.

This generally involves checking the hardness in all three zones, including weld , HAZ and base according to a pattern prescribed by the referenced specification. Hardness testing of welds is an extremely common practice and requirement in the oil and gas industry. You need to end up with straps 1-inch wide, from two different places [non-contiguous] in the coupon. Double ouch!!! The code referenced is AWS D1. If one is using the edition, look at figure 4. W is 1 inch if the pipe coupon is equal to or less than 4 inches in diameter. Best regards - Al. Red Flag This Post Please let us know here why this post is inappropriate.

Welder Performance Qualification (WPQ) as per ASME SEC IX
Simulation on the Stator of an Electric Motor: Electric motors and generators produce vibrations and noise associated with many physical mechanisms. This study looks at the vibrations and noise produced by the transient electromagnetic forces on the stator of a permanent magnet motor. Download Now. Simulation is an increasingly valuable tool across the product design workflow, but not all simulations are equal.
We set out to determine how engineers and product designers make use of specialized analyses, how they incorporate nonlinear simulation into their work and how they rate the available software.
