New Preheating Technology for Rolled Pipe in Fabrication

The majority of pipe welds completed in fabrication shops are rolled, and it’s easy to understand why. Rotating pipe while welding provides many benefits, including ease of achieving quality welds by eliminating out-of-position welding; reduced welding operator fatigue; and improved productivity from higher wire feed speeds and increased deposition rates.

RMD® MIG Process Enhances Stainless Steel Pipe Fabrication

Miller’s Regulated Metal Deposition (RMD®) MIG welding process (modified short-circuit MIG) improves welding quality and productivity on stainless steel pipe. The RMD process is easy to learn and addresses the welder shortage by providing an easier process that gets more work done faster and at a higher quality. Executive Summary Precisely-controlled metal transfer provides uniform […]

Advanced Inverter and Waveform Controls: AC Waveforms

In AC mode, an inverter offers waveform shaping with more control for optimal results. We’ll take a look at some of the benefits behind these waveforms. Some inverters bring control over the waveform itself to meet a specific requirement or operator preference. Some of the waveforms include: Advanced Squarewave, which gives fast transitions for a […]

Advanced Inverter and Waveform Controls: Amplitude Control

Independent amplitude control, available only on some inverters, allows the EN and EP amperage values to be set independently. Independent control of the EN and EP portions of the AC cycle allows the operator to direct more or less energy into the work piece, as well as take heat off the tungsten. For example, when […]

Advanced Inverter and Waveform Controls: AC Balance Control

In AC mode, an inverter offers waveform shaping with more control for optimal results. We are taking a look at some of the benefits behind these additional capabilities and how you can put them to use. If you missed the previous post, dedicated to DC Pulsing, or AC Output, we strongly recommend to read it. […]

Advanced Inverter and Waveform Controls: AC Output

As compared to a traditional TIG power source, a TIG inverter with advanced controls offers increased control over the welding arc. This allows the operator to tailor the bead profile, improve arc starting, increase travel speeds, perform better on thinner materials and thinner sections as well as experience other production benefits. In AC mode, an […]
