Patent Hollow Jointable air arc Gouging Carbon Electrodes

Patent Hollow Gouging Carbon Electrodes

1. Patent Hollow Gouging Carbon Electrodes

1.1 Description

AMT is the specialist in air arc Gouging Carbon Rods and have plenty of successful experience in satisfying our customers. Meanwhile, have got the patent of Hollow Gouging Carbon Electrodes .

The new product has the unique hollow design that differs from usual arcair gouging rods. This allows the electric current to be directed to and concentrated on the outside diameter of the rod. Therefore the efficiency of metal removal will increase and then resulting higher productivity.

The main advantage of Hollow air arc Gouging Carbon Electrodes is

	Higher Productivity
	50% faster than solid air arc gouging carbon rod
	Doesn’t stick or sputter
	Reduced smoke
	Creates smooth accelerated gouging

1.2 Specification

Electrical Resistance	≤ 21 μΩm
Breaking Strength	≥ 22 MPa
Density	≥ 1.5 g/cm³
Ash Content	≤ 1.5 %

Round, Jointable, Rectangular, Half-round rods or bars, Round or pointed ends, Solid or hollow rods, DC or AC rods are all available.

1.3 Application

Remove, Cut, and　Figurate　the defect　of solder, Slot U–groove for weld joints.

2. Formula for Rod Size Selection

Width of Groove (mm)= Rod Dia. (mm) X 1.40

Depth of Groove (mm)= Rod Dia. (mm) X 0.70

Arc Current (Ampere) = Rod Dia. (mm) X (40-50)

3. Packing

50pcs. or 25pcs. per cardboard box.
