Automotive Welding Repairs

We use several different types of welding equipment, relative to the application. The first is conventional Gas welding, also called oxy-fuel welding, is a system of welding that uses one of various gases and oxygen to ignite a torch. Welding is defined as the process of combining two materials, usually metal, by heating them until both ends become molten. Filler materials are generally added into this molten material, and the two ends are joined together and allowed to cool, forming one solid piece. At Executive auto body, we use gas welding very sparingly for accessory parts and as an aid in repairs.

The second is the much more commonly used “Mig” Metal Inert Gas welding, also sometimes called Gas Metal Arc Welding (GMAW) is a process that was developed in the 1940s for welding aluminum and other non-ferrous metals. MIG welding is an automatic or semi-automatic process in which a wire connected to a source of direct current acts as an electrode to join two pieces of metal as it is continuously passed through a welding gun. A flow of an inert gas, originally argon, is also passed through the welding gun at the same time as the wire electrode. This inert gas acts as a shield, keeping airborne contaminants away from the weld zone. The primary advantage of MIG welding is that it allows metal to be welded much more quickly than traditional “stick welding” techniques.

The final & most advanced system we have is called a Resistance welder. Quite simply, a resistance welder uses spot weld technology, (the same as the factory process), to secure new panels to the vehicle, the resistance welder allows us to create a perfect factory look to the replaced panels.
