Reciprocating wire feed gas metal arc welding (RWF-GMAW) is a low heat input, precisely controlled variation of the GMAW process. With the RWF-GMAW process the wire is reciprocated in and out of the weld pool. The wire motion is synchronized with the current waveform to produce a weld that is characterized as having minimal if […]
Read MoreCongratulations to EWI associate Miranda Marcus on her recently published article in Assembly (magazine): “Comparing Methods for Plastics Assembly.” Reading this article is a great way to learn more about plastics assembly. Explore the options for welding plastic parts — such as ultrasonics, laser, hot plate, and radio frequency — as well as factors to […]
Read MoreThe EWI Titanium Weld Color Inspection Kit – now considered the standard for visual inspection of titanium welds across all industries – has been upgraded to include new high definition color inspection cards. The redesigned card set was created using a new photographic technique which renders a more realistic, “truer” color image than that of […]
Read MoreCongratulations to EWI associate Miranda Marcus on her recently published article in Assembly (magazine). “Potential Pitfalls in Ultrasonic Plastic Welding” explores the design considerations that must be taken into account to ensure optimum results in ultrasonic plastic welding. The full article is found in the March 2014 issue of Assembly. Author: Miranda Marcus, Applications Engineer, EWI. The article is freely available online […]
Read MoreCongratulations to these EWI associates on their recently published article in the Welding Journal. “Exploring Arc Welding for Additive Manufacturing of Titanium” addresses how the gas tungsten arc process might be the answer for free-form manufacturing of parts, the size of which are not constrained by vacuum chamber dimensions. The full article is found in the March 2014 […]
Read MoreComponents made from titanium are candidates for additive manufacturing due to both the high material cost and the long lead times on material purchases. Electron Beam Freeform Fabrication (EBFFF) is the most widely used method for additive manufacturing of large scale titanium parts. This process is well established but is expensive and requires the parts […]
