What is a weldment?
A weldment refers to a structure or assembly created by welding multiple components together. It involves joining two or more separate metal pieces by melting and fusing them, often using heat, pressure, or both. This process results in a strong and permanent bond between the parts, forming a single integrated unit.
Weldments can range from simple assemblies to complex structures. Weldments play a crucial role in fabricating large and intricate metal structures efficiently and cost-effectively, offering versatility and customization options to meet specific design requirements and performance standards.
Our team of certified welders is capable of producing weldments ranging from ⅛” to 6” in diameter and larger. We have developed highly effective methods to create weldments in various shapes and sizes, meeting the specific needs and challenges of a wide range of customers.
TIG welding of stainless steel can be performed both with and without the use of filler metal, making it a versatile welding method suitable for various industries. There are two main categories of TIG welding, resulting in two different types of weldments.
Weldment Types
Autogenous weldments are produced by joining metal surfaces without the use of a filler metal. This method is often used when welding carbon and stainless steels due to their low heat-conductivity properties. It is also commonly used for relatively small welds. It is easiest to perform autogenous welding when the thickness of the metals to be joined is less than 5mm, though it can be done with thicker metals in some cases.
Homogeneous weldments are produced using a filler metal to join two metals together. When using this method, the filler material used will be the same as the base metal.
Heterogeneous weldments are produced when a filler material is used that differs from the base material. Soldering and brazing are examples of this type of joining process.
Weld Styles
Many styles of welds can be performed depending on what you’re trying to accomplish:
Autogenous
The autogenous method of welding is ideal for carbon and stainless steels due to their low heat conductivity and is used for relatively small welds. This type of welding service is performed by fusing two surfaces without the use of filler metal.
Freehand
Freehand welding is relatively easy to perform and is usually used to create flat, square, and small weldments. Creating consistency with this method, however, can be difficult.
Cup walking
Cup walking is an ideal welding method for use with larger-diameter piping, but it is a challenging method to master. The welds created using this method are consistent. The type of weldment you are trying to produce will determine whether you can use the cup walking technique.
Complex Geometries in Weldment Design
We take pride in our ability to tackle even the most challenging geometric designs in weldments. Whether it’s crafting detailed multi-axis manifolds or building precision frames, our TIG and orbital welding techniques allow us to create structures that surpass traditional joining methods. Thanks to digital modeling and precise fixturing, we ensure perfect alignment and dimensional accuracy throughout the welding process. The result is a consistently high-quality weldment with clean seams and reliable performance.
Cost-Effectiveness Through Smart Weldment Fabrication
A well-designed weldment can significantly save both time and money. We’re all about minimizing rework, scrap, and downtime by refining our welding and fabrication techniques. By reducing the number of joints, fittings, and connections, our weldments streamline the assembly process and help cut overall production costs. This means our clients benefit from faster lead times, consistent quality, and smooth project delivery, all while maintaining durability and precision.

Choosing the right welding services provider
There are many reasons why companies need to invest in welding services. As with any investment, it’s important to do your research to make sure you’re getting the best value for your dollar. It’s also important to understand that various factors can influence the cost of welding services.
The more experienced, better equipped, and properly staffed a welding services provider is, the better they should be able to minimize the overall costs. Therefore, when shopping for a welding services provider, you should determine what systems each organization has in place to deliver the highest quality products in a timely and cost-effective manner.
Welding is a time-consuming process, regardless of the welder’s experience. Time, therefore, is often the most expensive factor to consider. Of course, a more experienced and skilled welder will be faster by default and is more likely to find efficient ways to save time, which will ultimately impact the overall cost and quality.
Some examples of processes included in welding services where time is a significant factor include:
- Preparing joints
- Preparing materials to be welded (such as removing oils, blasting, etc.)
- Assembling joints
- Preheating joints when necessary
- Tack-up
- Positioning
- Welding (time will vary depending on how automated the process is)
- Removing slag when necessary
- Removing splatter
- Inspecting welds and joints
- Changing electrodes
- Moving welders from one location to another
- Changing welding machine settings
- Repairing/reworking defective welds
Because the cost of welding services can vary depending on the time required for each of the processes listed above, as well as the materials and equipment used, it’s best to work with an organization like Axenics that specializes in providing cost-efficient and high-quality welding services.
