etal and Non-Metal Cutting Techniques
Plasma jet high temperature and effluence rates support the cutting of practically any non-flammable material, including ferrous and
non-ferrous metals ceramic materials, concrete, stone A cutting rate of 7 mm (0,3 inch) per second can be achieved for low-alloyed
steels with thicknesses of up to 2 mm (0.08 inch), and up to 1 mm (0,04 inch) per second for thicknesses of 10 mm (0,4 inch)
Insulating materials are cut in MODE I.
Example Braze welding of Copper for Electrical Engineering Applications and Aluminum Alloy
thickness of mm, i.e. 0.12 inch) is beveled at degrees This surface is subsequently treated with the copper-zinc
braze ith specialized flux aluminum wire with flux for aluminum wire Tinned copper is welded to aluminum
using aluminum wire with flux for aluminum welding MODE I - “4” U = 140 - 150 V
Example Braze welding of luminum Tubing diameter mm thickness mm ( with Stainless Steel Tubing
diameter mm thickness mm (0,3 x 0,04 inches)
Stainless steel tubing is roughened with a coarse file, coated in aluminum flux and treated with aluminum wire filler. This area is
subsequently treated with flux for welding aluminum.Aluminum tubing is then brazed to stainless steel tubing using aluminum wire.
