Axenics’ advanced manufacturing processes ensure our team of expert technicians produce components that very often exceed customer expectations. Original equipment manufacturers require the highest-quality components for their semiconductor chip-making systems. Therefore, it’s essential for even the most-seasoned manufacturing journeymen to keep improving their skills, which is why we never stop learning.

The desire for smaller, faster, and, of course, less expensive, semiconductor components means the human element in manufacturing still has a long shelf life. There are simply some things our welders can do that robots cannot, such as perform miniscule, impeccable tolerances.

Gas tungsten arc otherwise known as tungsten inert gas (TIG) welding and orbital welding are used to create clean pathways for gases and chemicals to travel through semiconductor components.

TIG Welding for the Semiconductor Industry

The process of TIG welding involves a non-consumable tungsten electrode that delivers a current across the welding arc from the torch. When a weld pool is created, heat is applied to the joint with the arc actively melting the areas of the metals that will be united. The tungsten and the weld puddle are shielded and cooled typically with argon to protect the tungsten electrode from contamination.

TIG welding is an excellent solution for a process control system that requires high-quality, precision weldments in tight spaces. It’s the premier welding technique for producing welds that are free of discontinuities and defects, and allow for the seamless flow of gases or chemicals through a delivery system. TIG welding is versatile in that it can be performed on a wide variety of metals – as long as those metals are clean.

Axenics’ TIG welding is often performed in our Class 100 cleanroom, a controlled environment that prevents impurities from entering the weld area. This is ideal for welding components that will be used for semiconductor production, as contaminants are eliminated in this environment, which reduces the potential oxidation of the welds.

Orbital Welding for the Semiconductor Industry

Thin-wall, high purity, stainless steel tube welding is an efficient solution for creating custom, precision fabrications. The process is used in semiconductor component production to join tubes, pipes, joints and more, performed by a machine that can create the exact same weld time and again.

This is the preferred technique in situations where it is not feasible or practical to rotate a piece of tube or pipe to be welded. Orbital welding is also utilized when a weld must be executed in an extremely tight space that would not be possible with manual welding.

A Certified Welding Instructor is on the team to make sure weldments are produced to your exact specifications. Programmed welds that are identical time and again prove to be a significant time- and money-saver for our customers.

Weld testing is also performed on all welded components at Axenics in an effort to save both time and money. Non-destructive testing is the primary way to discover surface and subsurface weld defects prior to a component going into production.

One other thing to remember: As you look to maintain your existing output as well as develop new products, you may see your in-house resources thinning. Consider partnering with a longtime contract manufacturer like Axenics to take on some of these new projects. We have 35 years of experience and many resources for materials, space to develop new innovations and a dedicated team of experts.
