A Different Type of Bond – Hold the Filler Metal, Please

Solid state and resistance welding use pressure and/or electric current to fuse dissimilar metals, nonferrous metals, and composites without generating defects, like gas porosity and hot cracking, seen in fusion welding. Think things like bus bars and switches in automotive electric systems and appliances and nuts and fittings on various parts.

Amada Weld Tech’s CD-A1000A is a dual-pulse capacitive discharge welder. The dual-pulse function helps overcome surface inconsistencies – such as dirt and oil contamination – during the first pulse and makes consistent welds with the second.

The CD-A1000A from Amada Weld Tech Inc. (Monrovia, CA) is a 1,000 watt-second advanced capacitive discharge (CD) welder ideal for battery tab welding, honeycomb tacking, and welding of conductive terminals.

The unit is automation-ready and features dual-pulse output with control and monitoring of both pulses. The dual-pulse function helps overcome surface inconsistencies – such as dirt and oil contamination – during the first pulse and makes consistent welds with the second. A built-in process monitor measures peak current for both pulses; this value is displayed after each weld. Upper and lower limits can be set for both pulses to ensure weld consistency. An option to inhibit Pulse 2 if Pulse 1 is out of limits prevents weld blow-out. The process monitor helps operators assess performance with a color-coded bar graph that gives operators an instant weld history of in-limit/out-of-limit percentages.

Four pulse widths increase the range of welding applications and improve process optimization. Extremely efficient power electronics provide high repetition rates. Sixty-three schedules can be stored locally when a variety of welding processes are planned at the same station.
