When A.O. Smith, the company known for developing the glass-lined residential water heater, had a bottleneck at its resistance welding station and sought an alternate welding method. It had been making a lap welding on galvanized steel by resistance welding, but this trapped vaporized zinc; escaping vapors weakened the weld. A new method, a butt weld performed by laser welding, doesn’t trap the vapors, leaving a visually appealing weld that is essentially free of defects.

Before Thom Shelow founded Superior Joining Technologies Inc., he did quite a variety of welding, but his welding experience wasn’t the only asset he used to make the business a success. He keeps an open mind and is always ready to analyze new ideas, new concepts, and new technologies. “That’s the way we’ve always done it” doesn’t prevail at SJTI.

In 1973 full-time farmer Mike Van Mill tried his hand at building a grain wagon for a neighboring farmer, and he has been at it full-time since incorporating Brent Industries a few years later. Now the operations manager for Unverferth Mfg., Shell Rock, Iowa, Van Mill is part of a team that manufactures implements under the Brent brand name. The staff runs the facility like a savvy farmer runs a farm, always looking for a better way but proceeding cautiously. A sheet laser purchased in the early 2000s led to a tube laser purchased in 2014.

Former toolmaker Toolspec Manufacturing Co. has transitioned over the years to become a fabricator, and over the years acquired 14 hydraulic benders. The machines are capable but require lengthy tool changeovers, hours of programming time, and substantial expertise to maintain bend consistency. It recently invested in two all-electric machines, benders that don’t have these issues.

For structural fabrication-and-construction companies, efficiency in logistics is vital. A typical column, beam, truss or joist is handled three times—first to a storage yard, then to a staging area, and finally to the semitrailer. However, this isn’t the only way to do it. Reinicke Athens Inc. recently invested in a straddle carrier from Combilift Ltd. Instead of moving one part at a time, the truck lifts and moves an entire load a time, cutting its trailer-loading time from up to 8 man-hours to as little as 30 minutes.

An update from an article that ran in the September 2013 TPJ, this column describes a research project intended to help eliminate trial-and-error setups, conserve programmers’ time, and help get products to market faster by helping everyone involved in a bending project home in on the optimal bending process before getting started.

Bill Farris, owner of auto components supplier and repair shop Marden Tire & Auto, Rockford, Ill., focused on tires and repairs for many years, staying away from the inventory-heavy exhaust business.

Chromalox, a manufacturer of industrial heating systems, relied on skilled workers do quite a few manual processes, especially cutting and beveling. As the supply of people with this skill slowly dried up, the company realized that it would need to invest in an automated system. It chose an Ultra-Cut 400 XT plasma power supply from Thermal Dynamics (Victor) and coupled it to a 6-axis CNC pipe-handling system from Watts Specialties Inc.

Burger Boat Co. has weathered many a storm in its 150-year history, often changing direction to incorporate new technologies and adapt to changing market conditions. When the pleasure craft industry sank in 2009, it went after commercial work, and in the process had to develop a program for working in steel, which it hadn’t done in five decades or so. With the new process came new consumables from ESAB.
