Welding
Woolf Aircraft Products performs many types of metal joining processes which include welding and brazing. Welding Summary Woolf Aircraft Products, Inc. performs TIG welding mostly due to the quality and appearance of the welded joints that so many of our customers have come to expect. Certified Heli-arc Welding to AWS D17.1 (was Mil-STD-1595) in the following materials, Stainless, Carbon Steel, Aluminum, Inconel, Chrome Moly, and Titanium. We also are approved for Boiler Pressure Vessel Section 9. We have the ability to weld these materials in the thickness range of .012 to .250 inch. In addition, Woolf Aircraft can offer robotic 6-axis MIG services to reduce production time and cost for our customers.

Arc Welding (Stick) Arc Welding uses a consumable flux coated metal rod, which attaches to the end of an electric cable... the welding rod to the metal, which creates an arc and consumes the rod... on thicker metals and is easily used in the field. Woolf Aircraft seldom uses this process.		Metalarc Inert Gas (GMAW or MIG) In gas metal arc welding an electric arc between a continuously fed consumable wire and the base metal produces heat. The arc is surrounded by a shielding gas(es). It is often referred to as MIG welding.
Brazing & Braze Welding Woolf Aircraft employs the torch brazing and braze welding processes. Brazing is an adhesion process in which the metals being joined are heated but not melted. Both brazing & braze welding are metal joining processes which are performed at temperatures above 800 degrees, as compared to soldering which is performed below 800 degrees. Brazing – A process wherein coalescence is produced by heating to suitable temperatures above 800 degrees F, and by using a nonferrous filler metal having a melting point below that of the base metals. The filler metal is distributed between the closely fitted surfaces of the joint by capillary attraction. Braze Welding – A method of welding whereby a weld is made using a nonferrous filler metal, having a melting point below that of the base metals, but above 800 degrees F. The filler metal is not distributed in the joint by capillary attraction.		Resistance Spot Welding Resistance spot welding passes an electric current through the metal. Resistance to the electrical flow heats the metal to welding temperature. The process is used to weld together two or more overlapping pieces.
