TL;DR: In this article, a double-sided arc welding-brazing (DSAWB) was introduced to butt join AA5052 aluminum alloy and Q235 low carbon steel of 3.0mm thickness without groove.

TL;DR: In this article, the characteristics of laser lap welding of AZ31B magnesium alloy to Zn-coated steel were investigated and a 25mm wide joint failed in tensile shear testing at loads exceeding 6000 N. This high joint strength was attributed to the formation of a 450nm thick layer of Fe3Al intermetallic compound on the steel surface as a result of the interaction between Al from the AZ31b alloy and Fe.

TL;DR: In this paper, a waveform-controlled arc welding process with an arc welding torch and a power supply is described. And the power supply includes a sampling circuit for sampling instantaneous current and voltage values of the power during a snip portion (T snip ) of the process interval.
Abstract: An arc welding apparatus ( 10 ) for performing a waveform-controlled arc welding process includes an arc welding torch ( 14 ) that interacts with an associated weld. A power supply ( 12 ) applies a selected waveform-controlled power to the welding load via the arc welding torch ( 14 ) and a grounding cable over a process interval (T weld ). The power supply ( 12 ) includes a sampling circuit ( 34 ) for sampling instantaneous current and voltage values of the power during a snip portion (T snip ) of the process interval (T weld ). A processor ( 40 ) is designed to (i) compute a true heat over the snip portion (T snip ) of the process interval (T weld ), and (ii) extrapolate a true heat over the process interval (T weld ) based thereon.

TL;DR: In this article, a dual-stage power supply for creating a D.C. welding current through an arc welding gap is presented, consisting of an input inverter stage with a full wave rectified A.C voltage source and an output capacitor; and, an output chopper stage connected across the output capacitor.
Abstract: A dual stage power supply for creating a D.C. welding current through an arc welding gap, the power supply comprising an input inverter stage with a full wave rectified A.C. voltage source and an output capacitor; and, an output chopper stage connected across the output capacitor, with the chopper including output leads connected across the arc welding gap, a switch for gating the output current of the inverter stage at a controlled rate through the leads and through the arc welding gap, an output inductor in one of the leads between the switch and the arc welding gap and a free wheeling diode across the leads between the switch and the output inductor.
