TIGTechs welds stainless steel parts, tube and pipe to the code on your drawing. We are based in Dallas, Texas, and build for engineers, QC teams and buyers who need welds that pass inspection.
Every job runs to a qualified WPS, with a welder qualified to run it.
What is TIGTechs and what does it do?
TIGTechs is a B2B precision TIG welding and stainless steel fabrication company headquartered in Dallas, Texas. We weld parts, sanitary tube, aerospace assemblies and pressure piping for aerospace and defense, food and beverage, medical device, oil and gas, and semiconductor makers.
Precision TIG (GTAW) welding and stainless steel fabrication. That covers thin-wall parts, sanitary tube, aerospace assemblies, custom frames and enclosures, and code pipe and pressure work.
Design engineers, QC and QA managers, and procurement teams at manufacturers in regulated industries. Our buyers need records as much as they need welds.
Our headquarters and shop are in Dallas, Texas. We also serve Fort Worth, Houston, Chicago and Los Angeles. See all service locations.
Each service page lists the materials, standards and inspection methods that apply. Start with our flagship, precision stainless TIG welding, or browse the full services list.

Orbital TIG welding of electropolished 316L UHP gas lines to SEMI F78.
TIG welding uses a tungsten electrode and a separate filler rod. The welder controls heat and filler apart from each other. That control is why engineers call for TIG on thin, clean and critical joints.
Less heat means less warpage on thin stainless. It also keeps the metal out of the 800 to 1600 °F sensitization range for less time.
TIG makes no slag and no spatter. The bead is smooth, which matters for sanitary lines and parts that get polished.
Argon on the inside of tube and pipe keeps the root from oxidizing. A good purge prevents the gray, crusty root called sugaring.
We match filler to base metal, such as ER308L for 304L, ER316L for 316L and ER309L for stainless to carbon steel.
Every order follows the same path, so your QC team knows what records to expect.
We read the drawing, weld callouts and standards before we quote. Questions come back to you in writing.
We pick a qualified welding procedure (WPS) and a welder qualified to run it.
Welds get visual inspection plus any NDT your spec calls for.
Parts ship with the documents on your PO, such as material certs and inspection reports.
The more of this list you send, the fewer questions we need to ask. Missing an item? Leave it blank and we will help you sort it out.
2D prints with weld symbols and tolerances, plus 3D models if you have them.
Base metal grade and form, such as 316L tube or 304 sheet, and who supplies it.
Pieces per order, release schedule and estimated annual volume.
The governing code: AWS D17.1, AWS D1.6, ASME Section IX or 3-A.
Visual, penetrant, X-ray, ultrasonic or leak testing, and the sampling rate.
When you need parts and where they ship.
Codes, metallurgy, purge and heat control, and what drives fabrication cost, written by the people who run the torch.
We weld stainless steel parts, thin-wall tube, sanitary process lines, aerospace assemblies and code pipe. Send a drawing if you are not sure your part fits.
We quote both. Tell us your annual volume and release size so we can plan fixtures and labor.
We weld to the code your drawing calls out. Our current qualifications, such as AWS and ASME procedures, are listed on our certifications and compliance page. Ask for copies of the WPS and welder records with your quote.
