Welding FAQs

Welding is a method of joining two pieces of metal together by heating the surface edges to their melting point.

MCF welds the following products in shop: metal roof curbs, roof curb adapters, fan curbs, equipment rails, and isolation rails.

Arc Welding melts metals at the welding point by using a power supply to create an electric arc between the electrode and the base material.

Metal Inert Gas (MIG) Welding is an arc welding process where an electrode wire is placed between two pieces of metal in an arc zone. Heat is then applied, melting the metal pieces to the electrode wire and forming a joint.

Tungsten Inert Gas (TIG) Welding is a welding process, in which heat is generated by an electric arc that is between a tungsten non-consumable electrode and the work piece. The heat produced by the arc melts the metal piece edges and joins them together with a filler metal. For products made out of aluminum or stainless steel, Maryland Curb welds using TIG.

Shielded Metal Arc Welding (SMAW) is commonly referred to as stick welding. This is a manual arc welding process that uses a consumable electrode that is coated in flux to lay the weld.

Yes, at MCF we fabricate every piece in-house, creating your specific order from scratch through delivering a finished product.

The orders we receive primarily require MIG welding, however we have the capabilities to do stick welding (SMAW) as well as TIG welding.

At MCF we use both Lincoln and Miller welding equipment. We also utilize a Thermal Dynamics Torchmate (Plasma cutter) system, which cuts out each product by computer to ensure accurate dimensions.

Our staff visually inspects all of our welded components for size and quality of the weld deposit. We require fully welded, one piece construction and prime painted welds. All seams are sealed with elastomeric galvanized paint and we ensure there are no pinholes.
