TIG welding is particularly suitable for welding thin sheet metal and can be used for both continuous and spot welding. Learn more about its features.

TIG (Tungsten Inert Gas) welding sheet metal is certainly one of the most common welding methods. This is an arc welding process with an infusible (tungsten) electrode, protected by inert gas (the gases most commonly used are argon or helium), which can be performed with or without filler metal.

TIG welding is particularly suitable for welding thin sheet metal and can be used for both continuous and spot welding. This specific welding technology was initially developed for the aviation industry during the Second World War, to replace rivets with welds on planes (much lighter with the same resistance). Since then, its uses in the industrial sector have multiplied dramatically.

TIG welding sheet metal provides high quality joints and is therefore particularly suitable for welding thin sheets, unlike a traditional welding technique where the risk of piercing the metal is high.

TIG (Tungsten Inert Gas) Welding is most commonly used to weld thin pieces of stainless steel and non-ferrous metals such as aluminum, magnesium, and copper alloys.

• Versatile welding process with superior results
• Complex process requires a high degree of skill
• Slower yet more precise welding process; produces a superior-looking weld
• Can produce tricky welds, such as round or S curves

How TIG welding sheet metal works

In TIG welding, material is supplied manually with the help of a bar or automatically with a spooled wire. This procedure is suitable for performing high quality welds in case of joining thin stainless steel thicknesses by melting the edges, with small additions of material (in some cases even without filler material).

To TIG weld thin sheets, a torch is used in which the tungsten electrode is inserted, around which the protective inert gas flows on the melting bath. The operator moves the torch along the joint to move the melting bath, positioning the infusible tungsten electrode at a maximum distance of a few millimeters and keeping this distance stable.

During the operation it is very important to prevent the electrode from coming into direct contact with the piece to be welded, since the tungsten rod would stick to the joint and stop welding.

Thyhmetalfab: your point of reference for TIG welding thin sheet metal

This sheet welding process is an excellent solution to obtain results without burrs, but it takes highly specialized operators, especially when it comes to handling thin sheets, to obtain state of the art TIG welding.

At Minifaber we TIG weld sheet metal in-house, in a protected and controlled environment, thus optimizing times and costs for the creation of complex, finished or semi-finished products.

Our machine flee includes an MIG-TIG anthropomorphic welding robot and 8 welding machines entirely specialized in TIG, through which we manufacture both semi-finished and finished products with high added value.
