An October 2018 release from the World Steel Association predicted a small increase (1.4%) in global steel demand for 2019. That projection proved to be too conservative as the same report (pictured above) in October 2019 details increases of 3.9 percent due in large part to an unexpected rise in demand in China.. The year was challenging for the vast majority of

A HAZ forms in metals when the temperature rises above the critical transformation point. In laser cutting, this is localized near the cutting zone. In carbon steel, the higher the hardenability, the greater the HAZ. For example, laser processing produces a HAZ of about .18 millimeter on 7-millimeter-thick, 4140 steel. Welding 4130 to other unknown steel (either 4130 or 4140 Clamp steel-plate in the biggest vice in your workshop. Take a BIG hammer, or a heavy steel bar (say 1"+ round x 2'+ long), and bash away at the tube. You must keep going until either the bolt, or the weld, or the tube, parts company from the vice/big-steel-plate, and the end of the tube is lying on the floor. If weld fails, then BAD WELD!
