The construction industry’s use of hollow structural sections (HSS) has been on the rise since the recession. Because of their high strength, HSS allow engineers to use less material, extending the maximum unbraced length between structural members. It’s in this environment that the tube cutting laser is beginning to open up new opportunities.

Q: I weld in a large pressure vessel shop and use many welding processes, including SMAW, GMAW, FCAW, and SAW. Regardless of the process, our work clamps always get very hot. We’ve even had some arcing from the ground clamp. We have welded several grounds to the workpiece to remedy this problem,...
