Q: The company I work for takes on jobs at the last minute, which makes it harder for me to work at the level that the customer requires, especially providing material test reports (MTR). I cannot provide all the MTRs our customer requires. Often we don't get them from our vendor, or parts have sat...

To pursue visual art or science, that is the question. Polar-opposite interests? Yes. But who says the two can’t intersect somehow. After all, elements of science are alive in metal forming and fabricating, but to make it visually pleasing, an artist’s touch is necessary. Metal art, it would...
A road map to robotics

Implementing robotics can prove to be beneficial, but you can’t expect to achieve your desired productivity results if you don’t know how products flow to and from that cell. In other words, simply throwing a robot onto the shop floor is not the answer. Before you make the commitment to robotics, it’s important to analyze your process flow and adopt methods that will help reduce waste from the manual process.
Metallurgy for welders

The goal when welding any material is to change its microstructure as little as possible and to preserve its mechanical and chemical properties. To achieve this you must be able to determine its weldability, control the heat input, and prevent rapid cooling.
Aluminum MIG

- Article
The push for lighter, corrosion-resistant components has brought aluminum to the forefront of the minds of traditional steel fabricators. Those that approach the material the same as steel often run into weld quality issues that can prove costly. But those who are committed to putting together a topnotch, aluminum-friendly system before striking an arc—from equipment and setup to material preparation and welder education—are better equipped to find success afterward.
