Air pressure for plasma cutting is not a single number you set once and forget. Shops that treat the compressor gauge reading as the only variable end up with beveled cuts, short consumable life, and intermittent arc starts. The correct approach is to maintain stable dynamic pressure at the torch inlet while keeping the air […]

FANUC Arcmate robots are six axis industrial arms built specifically for arc welding, and they appear most often in shops that have stopped tolerating inconsistent manual welds. The series combines welding specific cable routing, arc process interfaces, and repeatable motion so a cell can hold torch angle and travel speed across hundreds of shifts. In […]

A machine beam does most of its work before the equipment runs. As an industrial welding automation engineer, I have seen gantry systems pass static inspection and then fail under travel load because the beam was welded, stress relieved, and machined out of sequence. A fabricated steel machine beam carries the linear rails, cutting head, […]

Longitudinal seam welding determines whether a shell, tank or pipe spool holds pressure and keeps its roundness. In the failures I have investigated, the cause usually appears before welding begins: uneven root gap, a drifted tack line, or a carriage that does not travel straight under load. For buyers and welding engineers planning pressure vessels, […]

American Welding Society standards shape how welding procedures, welder qualifications, and equipment parameters are written across structural, pressure vessel, and pipeline work. The AWS publishes consensus documents that define acceptable joint design, filler metal selection, inspection rules, and qualification records. Too many equipment buyers treat AWS compliance as a paper checkbox, but the practical question […]

Weld.com has grown into a substantial online resource for welders, fabricators, and welding supervisors. It combines video demonstrations, interviews, written articles, and podcast discussions that cover processes, equipment, career paths, and shop techniques. I have used parts of that library in my own work as an industrial welding automation engineer, not as a substitute for […]

A thin oxide film can stop filler metal from wetting a joint, and that is why liquid flux still has a place in welding, brazing, and soldering work. I have seen line operators reach for it as a quick fix, but the better approach is to treat it as a process control variable. Liquid flux […]

Laser beam welding process performance turns on power density. Once a focused beam exceeds roughly 1 x 10^6 W/cm², it forms a keyhole: a small vapor cavity surrounded by molten metal, which collapses behind the advancing beam and leaves a deep, narrow fusion zone. I have seen shops produce excellent battery enclosure welds with fiber […]

Flux core MIG welding earns its keep on the jobs where solid wire falls short: field repair, rusty plate, and structural work in open air. The process runs a tubular wire filled with flux, so the arc gets shielding without an external gas cylinder. I have seen shops overcomplicate this method, but the decision usually […]

Most homebuilt mini spot welders are built around a reused microwave oven transformer, and the first version either melts through the nickel strip or cannot hold a weld. I have seen the same pattern repeatedly: the current is there, but the control is not. A safe and useful spot welder needs three things: a controllable […]
