Capabilities Of TIG+MIG Welding Motor Lamination Stacks

The capabilities of TIG + MIG welding in motor lamination stacks are marked by a fusion of precision, strength, and adaptability. This advanced welding technique reduces core loss and eddy current and improves electrical machine energy efficiency.

TIG Welding

TIG welding(Tungsten Inert Gas) is a bonding metal process. This process utilizes a non-consumable tungsten electrode to create an electric arc that generates the heat required to melt and fuse the welded metals.

A shielding gas, often argon, protects the weld area from atmospheric contamination, and a filler metal is usually used. The gas forms a protective shield around the arc and the molten weld pool, preventing oxidation and ensuring a clean and strong weld.

This welding technology produces clean, precise welds on any metal, ensuring laminate the stator stacks together with quality. TIG welding is normally used for thin material and medium-sized cores.

MIG Welding

MIG welding, which stands for Metal Inert Gas welding. It is also known as the Gas Metal Arc Welding process(GMAW) or MIG welding.

In this process, an electric arc is formed between the metal being welded and a continuously fed wire electrode, melting the wire and the base metals. A flowing inert gas(such as argon or a mixture of argon and carbon dioxide) shields the process to protect the weld from atmospheric contamination.

This technology is our commonly use welding method for HV stator cores. MIG welding is suitable for thicker materials and larger-sized motor/generator cores.

MAG welding is a mixed gas-shielded welding in which a small amount of oxidizing gas (oxygen, carbon dioxide, or mixed gas) is added to argon. It mainly applies to welding black metals such as carbon steel, alloy steel, stainless steel, etc.

Benefits Of Motor Core Bonding Use Of Welding

TIG Welding Benefits

Weld Quality: TIG welding produces high-quality, precise welds with minimal defects. Its precise control over heat input and arc length results in clean, aesthetically pleasing welds that require minimal post-weld finishing.

Minimal Heat Distortion: TIG welding generates a focused, concentrated heat source. This reduces the heat-affected zone (HAZ) around the weld, minimizing distortion and maintaining the integrity of the material.

Reduced Weld Spatter: TIG welding produces minimal weld spatter, reducing the need for post-weld cleanup and saving time and resources.

High-Purity Welds: Using inert gases and the absence of flux in TIG welding makes high-purity welds resistant to corrosion and oxidation.

MIG Welding Benefits

High Welding Speed: The continuous feeding of the electrode wire allows for uninterrupted welding, making it a quick and efficient welding process. It’s particularly suitable for high-volume production environments.

Ease of Use: MIG welding is relatively easy to learn and operate, making it accessible for beginner and experienced welders. This contributes to faster training and skill development.

Less Heat Distortion: MIG welding generates a relatively lower heat input than other welding methods, reducing heat distortion in the workpiece.

Shielding Gas Variability: Different shielding gas mixtures can be used in MIG welding to optimize the process for specific materials, weld joints, and outcomes.
