Industry Focus: Structural Fabrication

Welding News for Fabricators To assist our customers in the structural fabrication industry, Lincoln has created the following information center. Structural welding codes cover various aspects for fabricating and erecting welded structures. Lincoln is here to help you follow the guidelines set in these codes and create the highest quality welds.

Feature Story   NEW! D1.8 Tested and Approved Lincolnweld® Wire & Flux Lincoln Electric now offers AWS D1.8 tested and approved Lincolnweld® wire and flux for submerged arc welding in seismic zones. This addition to Lincoln's portfolio of AWS D1.8 approved products gives structural fabricators additional documentation to suit their specific welding needs.

AWS D1.8 Resource Center   AWS D1.1 Resource Center Lincoln Electric created this D1.8 Resource Center with tools to understand seismic welding guidelines and links to Lincoln Electric consumables tested to meet the AWS D1.8 and FEMA 353 requirements. The development of Lincoln Electric’s D1.8 Resource Center is just one more way Lincoln sets the standard for the welding industry, worldwide. D1.8 RESOURCES D1.8 Supplement Lincolnweld® Product Catalog Innershield® Welding Guide Innershield® Product Catalog UltraCore® Product Catalog Certificates   New AWS D1.1 Testing for MIG Shielding Gas In order for fabricators to use a pre-qualified WPS for gas shielded processes listed in AWS D1.1, the fabricator must be able to supply documentation that the electrode & shielding gas combination in use is capable of meeting all the mechanical and chemical property requirements for the electrode classification, when tested in accordance with the applicable AWS A5 specification. In the case of the mild steel GMAW process, AWS A5.18 requires the use of 100% CO2 shielding gas. However, a variety of shielding gases or shielding gas combinations can be used in this process. In this case, additional testing and documentation is required for each variation of shielding gas used at the expense of the fabricator. Lincoln Electric understands the needs of its structural fabrication customers and goes beyond the AWS requirements for manufacturers. By providing statements of test, for not only 100% CO2, but many other commonly used shielding gas mixtures, Lincoln Electric saves it structural fabrication customers the time and money associated with additional testing.
