What is Microscopic TIG Welding?
Microscopic TIG welding, also known as GTAW, uses low amperage for precise welds. The reduced heat output and machine control reduce the risk of warping; ensuring a repeatable process. The smallest weld sizes can be completed with exact precision using microscopic TIG welding.

Microscopic TIG welding is often a small, yet critical step in the manufacturing process of intricate medical device assemblies and other intricate parts. This process is performed under a high-powered microscope. This additive process utilizes sophisticated power sources that can produce very stable low amperage welding.

• Aerospace component repair and manufacturing.
• Plastic Injection Mold and component repair and engineering revisions.
• Machine component and critical part repair and manufacturing.
• Medical device repair and manufacturing.

This is the ideal process for small, intricate welds that can’t be performed using normal TIG welding, such as areas too large for laser welding, and areas where it is necessary to reduce the risk of warping in the heat-affected zone. The system uses gas tungsten arc welding (GTAW) with a microscope for up-close vision. The low amperage inputs and small diameter wires decrease warping on the heat-affected zone (HAZ) on thin inserts and cores.

Micro Tig Welding Advantages:
• Achieve a deeper penetration
• Reach difficult areas
• Durable and discrete welds
• Lower cost than remaking the damaged part
• Fast and less expensive than laser welding
• Welds as small as 0.005 mean less machining and hardworking is needed

All micro-TIG welding jobs are pre-heated to ensure the best quality welding. The cost of micro-welding is less than having to remake or rebuild a damaged part.

TIG welding has always been the staple welding process critical to the performance of tools, dies, molds and inserts. The TIG welding process allows operators to control heat input and the amount and location of weld metal deposited. Tool and die welding typically involves building a larger surface area so that it can be re-machined to desired tolerances.

The microscopic TIG welding process definitely isn’t for beginners. There are countless factors that need to be taken into consideration. Contact Nu-Tech today, our experienced technicians will get you sorted out in no time!
