EBE Reduced Raw Material and Tightened the Production Belt for Fat-zapping Device

May 14, 2015

By:

Production difficulties due to the complex design of a heat exchanger for ZELTIQ® Aesthetic Inc.’s CoolSculpting® equipment designed to selectively reduce fat caused the company to fall behind on shipments. A redesign by Electron Beam Engineering Inc., Anaheim, Calif., reduced the amount of 5052 aluminum needed by about 15 percent, simplified production for a 20 percent time savings, and upped quality to over 99 percent. The 15-in.-long electron beam welds are pressure-tight, narrow, and do not require postweld finishing.

Measuring weld heat to evaluate weld integrity

May 14, 2015

By:

Eddy current and ultrasonic testing are suitable for tube and pipe mills and have been used for weld seam flaw detection for decades, but a new process, thermography, is an alternative. By measuring the heat signature of the weld seam as it cools, it provides information about weld integrity at and below the surface.

Vision-guided robots consolidate their place in the press shop

May 13, 2015

By: ,

Advancements in robotic technology are extending their functionality and improving their performance. Often a robot is expected to do more than move from programmed position A to position B; it must operate “smarter” and act upon other inputs, such as vision systems or force feedback. The applications for integration of vision systems and robots are almost endless but the most common application is vision guidance for the robot

Arc Welding 101: Plugging holes and pinholes

May 12, 2015

By:

Q: I am machining a bearing housing made out of 1045 and I have to plug and weld some cross holes. I am also using gas tungsten arc welding (GTAW) to eliminate a weld that is too large. My problem is that I am getting pinholes in my weld. Is it because I am welding 1018 to 1045? We didn’t machine...

Consumables Corner: Eliminating weld cracking in restrained joints on high-strength steel

May 12, 2015

By: , ,

Q: We're a construction equipment manufacturer that is finding that our customers increasingly require more components designed and manufactured from high-strength steels such as A514 or 4130. This means we have to preheat and follow slow cooling conditions, but even then certain joints or...

Aluminum Workshop: What to know when changing shielding gas with pulsed GMAW

May 12, 2015

By:

Q: Recently I bought a new high-end pulsing power supply, which has different modes for all of the common materials and wire diameters. I was getting great results with 3/64-in. 5356 wire and 100 percent argon shielding gas. When I changed to a mixture of 70 percent argon/30 percent helium, the arc...

Going beyond OSHA regulations for manganese exposure

May 11, 2015

By:

Complying with OSHA guidelines for manganese exposure during welding may not be doing welders any favors. One Oregon metal fabricator invited OSHA into its shop and to look for ways to reduce the potential of manganese exposure. The combination of low-manganese welding wire and proper ventilation positioning appears to have cleared the air on this subject.
