AC/DC Submerged Arc Productivity Advantages Applied to Robotics/Automation
Submerged arc welding (SAW) that combines the advantages of AC and DC SAW welding was not possible until a few years ago. This technology now is increasingly applied to structural steel automation applications.
The latest technology provides for control over the ratio of positive to negative amplitude, as well as the amount of time spent at each polarity. The limiting factor for SAW AC welding is that it takes too long to cross from electrode positive (EP) to electrode negative (EN). This lag can cause arc instability, penetration and deposition problems in certain structural applications. AC/DC SAW solves this problem by controlling amplitude and frequency, allowing the automated process to take full advantage of the reduction in arc blow experienced with AC, while maintaining the penetration advantages of DC positive and the advantageous deposition rate of DC negative. Using these controls, the shape of the output waveform is changed, and in turn the welding characteristics are controlled. With AC/DC submerged arc welding, you get the best of both worlds: the speed, deposition rate and penetration that DC SAW offers and the resistance to arc blow that AC SAW offers.
Our tank turning rolls can work with column boom to perform SAW for pipes, tanks, pressure vessels, etc.
