TIG welding rods 1.2 mm are filler materials of this diameter used in TIG welding for manually feeding material into the weld pool to create precise, durable joints. The rod type depends on the welded material, for example carbon steel (SG2, SG3), stainless steel (308L, 316L) or aluminium (4043, 5356). They are used for welding thin sheets and elements in the aerospace, automotive, medical and food industries.
For carbon steel: Rods such as SG2 or SG3 (with higher silicon and manganese content) are used to create strong joints.
For stainless steel: Choose rods marked as 308L, 316L, or 309L, which provide corrosion resistance.
For aluminum: Depending on the needs, you can use rods from the 4043 series (for better fluidity) or 5356 (for greater mechanical strength).
For other applications: There are also rods available for welding copper, brass, and bronze, as well as for other metal alloys.
What 1.2 mm TIG welding rods are used for:
Precision welding: The TIG method with 1.2 mm diameter rods is ideal for welding thin sheets and components where high precision and control are needed to avoid excessive heat and burn-through.
Creating aesthetic welds: They allow for smooth and aesthetic welds, which is crucial in industries where appearance matters.
Filling gaps: They serve as additional material for filling joints, creating durable and solid connections.
Applications in various industries:
Aerospace industry: For manufacturing engine components and fuselages.
Automotive industry: For welding precision parts, e.g., exhaust systems.
Medical equipment: In the production of medical devices and tools that require high-quality connections.
Food industry: For welding components of installations that must be corrosion-resistant and easy to clean.
The 1.2 mm TIG welding rod is mainly selected based on the thickness and type of material being welded, but the selection should also consider the type of welding (steel, aluminum) and the fact that the rod should typically be one size smaller than the thickness of the material being welded to avoid excess heat and burn-through. When welding thin materials, a 1.2 mm rod is often a good choice.
Key factors in selection
Material thickness: Typically choose a rod with a diameter one size smaller than the thickness of the base material being welded. For example, for welding material with a thickness of 1.5 mm, a 1.2 mm rod will be suitable.
Material type: Ensure that the chemical composition of the rod matches the composition of the material you are welding, e.g., welding stainless steel or aluminum.
Purpose: The 1.2 mm rod is often used for welding thin materials, such as sheets, as it allows for better control over heat and prevents burn-through.
Type of welding: When welding thin sheet materials, a rod with a diameter of 1.0–1.2 mm is a good choice. For thicker materials, it is better to use rods with a larger diameter, e.g., 2.0 mm.
