Since 1960, National Element Inc. has partnered with major manufacturers to create solutions for their industrial heating needs. We customize products to perform in a diverse variety of furnaces.

Welcome to my part of “Technical Talk,” where we will discuss brazing, a very important metal-joining technique that continues to grow in usage each year in many industries around the world. Most people are familiar with welding and soldering, but many are not familiar with where brazing might fit into the overall metals-joining landscape.

SMS group supplied a high-frequency tube welding line to Spain’s Bornay SL. The tube welding line enables Bornay to produce high-quality tubes with round, square or rectangular cross sections and yield points up to 1,200 MPa. It can produce tubes with diameters of 10-40 mm and wall thicknesses up to 4.5 mm. Tubes with square cross sections are manufactured in dimensions up to 30 x 30 mm and rectangular products in dimensions up to 40 x 20 mm with wall thicknesses up to 4 mm.

Stupp Corp. awarded SMS group a contract to extend the spiral pipe mill at its facility in Baton Rouge, La. The contract consists of two projects: a partial revamp of the spiral pipe machine to increase pipe production capacity and a new submerged-arc re-welding stand to complement the existing three welding stands. The plant’s modifications, which can increase Stupp’s annual capacity by 40,000 tons (to 60,000 tons) will go into operation by the end of 2020.

French state-controlled utility Electricite de France (EdF) previously notified the country's nuclear safety authority, ASN, of deviations in the manufacture of some steam-generator welds for its nuclear reactors. The "deviation from technical standards" involved the “detensioning heat treatment on the welds” (stress relief).

As a metallurgist, I am frequently asked for assistance on metallurgical issues relating to alloy products and selection. Here are the most frequently asked questions and a guide to answering these questions.

The Norton Pneumatic Die Grinder accomplishes a wide range of portable grinding applications without the need to change machines.

International heat-treatment codes and standards require welders to conform to heating parameters for the target workpiece, including heat-up time, temperature uniformity, soak time and cool-down time.

The WMC SafetyRobot telerobotic welding system allows operators to perform remote floodwelding in a temperature-controlled environment.

Air Liquide and its U.S. subsidiary, Airgas, opened the Advanced Fabrication Center (AFC) at the Air Liquide Delaware Innovation Campus in Newark, Del. The AFC focuses on helping industrial customers adopt new manufacturing technologies and more efficient and cost-effective production processes. It will deliver a continuous flow of development projects, innovations and exploratory R&D. Air Liquide’s manufacturing expertise in welding gases and advanced fabrication processes will be on display at the center.
