Property maintenance includes so much more than fresh paint and vibrant landscaping. Over time, the materials that make up your structures and equipment will wear with age, usage, and exposure to the elements and environmental contaminants. When pipes, handrails, or heavy equipment made of metal start to rust or deteriorate, you’ll need experienced welders on the job to return them to a safe and usable condition.
Lightning Mobile Services is pleased to supply a highly-trained team of expert craftsman to manage your welding needs, no matter how large or small. While we don’t offer underwater welding, we can handle any other project, and we offer proficiency in:
- MIG welding
- TIG welding
- Stick welding
- Flux core welding
In addition to offering repair services, we can also attend to metal fabrication, for times when you need a custom solution. We are available 24/7 for emergency maintenance services.
Probably the most common type of welding, MIG (metal inert gas) welding is a form of arc welding that relies on the use of a consumable wire electrode that is fed through the nozzle on a torch (or welding gun). When activated, the electrode forms an arc between the metal surface, or base metal, and the wire, both of which melt under the heat.
The melted electrode creates a bead of filler metal that joins the two pieces of base metal together. Shielding gas is also fed through the nozzle to protect the molten metal from reacting with gases in the atmosphere so that the weld can cool and harden properly.
MIG welding is relatively versatile, and can be used for both thin and thick metals (although not the thinnest or thickest), provided you have proper equipment and an experienced professional on the job. It can also be used to weld different types of metal together, since they are joined by the filler material, rather than bonded to each other.
Unlike other types of arc welding, TIG (tungsten inert gas) welding does not rely on a consumable electrode, but rather a non-consumable tungsten electrode that supplies the arc and heat needed for welding without introducing any filler material. Like MIG welding, a shielding gas is used to protect against interference by atmospheric gases.
This type of welding is extremely versatile for a couple of reasons. First and foremost, it can be performed with or without filler metal. If two pieces of metal are compatible, they can simply be joined together with the heat created by the arc. Otherwise, our welding professional can introduce a welding rod (in two-handed operation), melting it into the base metal.
Second, it’s easy to control the heat produced by the TIG welder, so that it can used with a variety of metals, from aluminum to steel. That said, it is only suitable for welding thinner metals, but on the upside, precision welds are possible. Because no filler metal need be used, TIG welding often results in extremely clean welds.
Stick welding is a type of arc welding relies on the use of a consumable electric rod, or stick. When electric current is passed through the stick, it forms an arc between the stick and the metal surface being welded.
This produces high temperatures that melt the base metal and the consumable metal in the electrode. As the metal from the electrode melts, it drips onto the surface, creating a bead that cools and hardens to form the weld.
Because stick welding creates extremely strong welds, it is frequently used in fields like construction, or for heavy-duty repairs. It’s suitable for welding thick materials, like cast iron, that are too robust for other types of welding. Stick welding tends to leave a thick bead and slag behind, which could require finishing work if appearance is important.
Flux Core Welding
Flux core welding is similar to MIG welding, but instead of using a bare wire consumable electrode, the wire contains a flux-filled inner core. In some cases, a shielding gas is added, but the flux itself may also supply this atmospheric protection during welding. The latter eliminates the need for gas shielding equipment (essentially, gas tanks hooked up to welding equipment).
The main advantage of flux core welding is that it can be used outdoors, where breezes might otherwise disrupt shielded gas applications. It’s also more portable and offers speedier application than some other types of welding, and it is suitable for thicker welds.
