Resistance welding is the fastest, cleanest way to join metal sheets at scale – no filler rod, no shielding gas, and no open arc. Joule heating — the same principle that powers a spot welder on an automotive body line…

Friction stir welding (FSW) solves the problem arc welding cannot: joining high-strength aluminum alloys that crack when they cool from a liquid melt. Since Wayne Thomas invented the process at TWI in 1991, FSW has expanded from aerospace R&D into…

A welding procedure specification is the backbone of your welding operation, controlling how every qualified weld is made – the procedure, materials, parameters, and tests used to turn an as-delivered joint into a code-conforming weld. A weld procedure specification that…

Every time an arc strikes, the weld pool e×pels a puff of metallic o×ides, silicates, and gases that no ventilation fan mounted in a wall fifty feet away is going to do anything with. A properly specified welding fume e×tractor…

What Is Weld Testing — and What Happens When a Weld Fails   Weld testing is the inspection of completed welds to ensure that they are up to code with respect to the required component structural strength and dimensions prior…

Each structural weld has a load calculation. That load calculation assumes a good joint – one without cracks, unconsolidated regions and porosity that can cause fatigue failure under cyclic loading. It is the weld inspection that allows engineers to verify…

Aerospace welding sits at the demanding edge of metal joining. A single porosity-filled fillet on a turbine casing or a cracked friction stir seam on a cryogenic fuel tank can ground a fleet — or worse. This guide covers the…

A welding positioner is the difference between a 60 percent arc-on rate and a 30 percent one – and on a busy fabrication floor, that difference is worth tens of thousands of dollars a year. The problem is, no two…

Industrial welding is the foundation of present-day heavy manufacturing — every steel building, ship hull, pressure vessel, wind tower, and chassis frame relies on weld joints that meet defined codes and survive decades of cyclic load. Practice has shifted noticeably…

Structural welding stands at the convergence of three pressures in 2026: a dramatically updated code (AWS D1.1:2025), a labor force hell-bent on automating faster than they did with FCAW in the ’80s, and a steel industry currently de-GA-ing, 50% re-shoring,…
