Specialized Mobile Welding service, offering TIG, MIG, Oxy-Acetylene, stainless steel, and aluminum welding.
Specialized Welding Service serves Miami-Dade, Broward, and Palm Beach Counties. Our mobile welding service comes to you, at your business, home, garage, dock, or roadside location. Mobile means more than just showing up at your location. Our mobile “welding shop” is completely portable. We bring everything needed, including a generator to power our electric welders.
Mobile welding for wrought iron, structural modifications, and automotive customization. We weld and repair trailers, railings, handrails, fences, gates, security bars, brackets, tools, grates, frames, motor cycles (and more). Specialized Welding Service does oxy-acetylene cutting, welded structural repairs, and steel fabrication.

Welding - What is it?
Welding is the process of melting metals or thermoplastics and adding a filler material to fill gaps and produce a secure coalescence between the original materials. Welding naturally produces a stronger bond than soldering or brazing because the original materials are melted and interact in a molten form to create a juncture that is nearly as strong (sometimes as strong or stronger than) the surrounding materials. Welding rods, wire, or sticks of differing materials act as fillers and/or catalysts in forming the bond.
Although welding is performed in a number of ways, in this commercial context we are concerned with the various types of electric arc and gas flame welding. These methods are simpler and less expensive than plasma, laser, ultra sound, forge, or pressure welding. For commercial and residential applications oxy-acetylene welding, shielded and non-shielded arc welding, MIG and TIG welding are sufficient to fabricate or repair common applications.

Oxy-Acetylene Welding Oxy-acetylene welding combines oxygen and a fuel (acetylene) to produce an extremely hot flame that melts metal. A filler material is usually added to supply material for filling space between the materials to be joined. Oxy-acetylene torches are also used for metal cutting. The hot flame cuts metal by melting a kerf through the material. Waste material flows away as oxide slag. |
Non-shielded Arc Welding Non-shielded arc welding requires a strong electrical source at high current. Thicker materials demand higher current. The welder must melt the two pieces to be joined, forming and maintaining a constant-sized plasma pool as the weld advances. Advanced skill is required to produce a clean, even weld. |

Shielded Arc Welding Shielded arc welding is also commonly known as stick welding. The stick, or welding rod, can be made of any number of alloys and is usually coated with a flux material that, as it is consumed in the heat, forms a protective gaseous shield around the weld that allows the operator to work without the need for exact control, speed and electrical current. |
MIG Welding MIG Welding (metal inert gas welding) uses a consumable wire that is automatically or semi-automatically fed through a welding gun along with an inert gas to shield the weld from splash-producing ambient atmosphere oxygen and other active gas traces. This process can produce a clean, even weld that is strong and unimpaired by bubbles or impure slag. MIG is the most commonly used welding method in commercial applications. |

TIG Welding TIG Welding is especially suited for lightweight stainless steel, aluminum, magnesium, and copper alloys. It employs a non-consumable tungsten electrode and an inert shielding gas, usually argon, to produce a finely controlled weld. The advantage of fine control is balanced by the disadvantage of being much slower than other types of welding. A filler metal is usually added although some TIG welds can be made autogenously with no filler. |
