THE PLASMA ARC WELDING ADVANTAGES:
The plasma welding process offers two prime benefits: Improved weld quality and increased weld output. Plasma welding offers advanced levels of control, arc stability and weld consistency for high quality welds either in miniature or precision applications.
The plasma process is equally suited to manual and automatic applications. It has been used in a variety of operations ranging from high volume welding of micro components, to precision welding of surgical instruments, to automatic repair of jet engine blades to the manual welding for repair of components in the tool, die and mold industry.
MICROPLASMA ARC WELDING ADVANTAGES:
How Plasma Welding Works: The system requires a power supply and welding torch. In the plasma welding torch a Tungsten electrode is located within a copper nozzle having a small opening at the tip. A pilot arc is initiated between the torch electrode and nozzle tip. This arc is then transferred to the metal to be welded.
By forcing the plasma gas and arc through a constricted orifice, the torch delivers a high concentration of heat to a small area. With high performance welding equipment, the plasma process produces exceptionally high quality welds on a variety of materials.
FEATURES AND BENEFITS:
Protected electrode, offers long times before electrode maintenance (usually one 8 hour shift)
Low amperage welding capability (as low as 0.1 amp)
Arc consistency and gentle arc starting produce consistent welds, time after time
Stable arc in arc starting and low amperage welding
Minimal high frequency noise issues, HF only in pilot arc start, not for each weld
Arc energy density reaches 3 times that of GTAW. Higher weld speeds possible
Weld times as short as .1 second
Energy density reduces heat affected zone, improves weld quality
Length of arc benefits due to arc shape and even heat distribution
Diameter of arc chosen via nozzle orifice
