Aluminum Welding

Aluminum welding can be challenging, even for experienced welders. For example, a top layer of oxide takes longer to heat up than the aluminum underneath. The heat difference is a challenge because aluminum has a low melting point yet holds heat well. The second challenge is contaminants such as dirt, water, and oils getting into the weld. Contaminants can be severe as they create weak welds. Our ability to overcome these challenges comes down to two things: an experienced team and AWS training.

We hold AWS certs in steel, stainless steel, and aluminum. Also, we have a full-time CWI who inspects welds and writes WPS/PQR. Our expert weld team has extensive training and aluminum welding experience. We can send you weld samples or connect you with our CWI to talk about procedures.

When it comes to aluminum welding, we serve the space and nuclear industry. That is to say; we are used to making quality parts because our customers set the bar high. Therefore, it is rare to come across a job or product that we cannot handle from a quality point of view.

Our goal is to build long-lasting partnerships. If you share that same goal, get in touch with our sales team. Email or schedule a meeting.

Quality built into every process.

Properly inspecting parts is an important aspect of our business. However, if you are catching errors during the inspection process, it is often too late. There are significant expenses associated with rework, and many times errors will lead to late deliveries. This is why we build quality into every process. For example, we have kickoff meetings for each job. Our welders, machinists, programmers, project managers, and painters meet and review technical data in close detail. This helps iron out potential issues on the front end. We have also invested in the BLUCO Floor Rail System, which is a precision modular welding tool.

Closeup on Aluminum Welding

There are times when our team must weld aluminum while it is vibratory stress relieved.  The product on the left is an example of that process.  To the right is a close-up weld shot, which shows the skill of our welders.

Do we have the certifications needed to work on your aluminum welding project?

Standing out in a sea of fabrication and machine shops.

Thousands of welding shops can produce aluminum products. But, if you want to stand out in the crowd, you have to do more than deliver quality products on time. That is why we focus on service. From quote to delivery, we let the golden rule guide us. For example, we send a weekly report that shows what is going on with your part. If a machine part is running behind, we report it.  We won’t always get it right, but we will make it right.  You don’t have to take us at our word; check out our customer feedback.

Are short lead times important to you?

Our scheduling tool sends out lead time notices when a machine or department gets low on work.  This allows our customers to take advantage of cheaper rates and faster turn-around.
