For any metal fabrication process done with Xometry, we provide additional weldment services to assemble your project using our extensive network of professionals. We do all types of welding–we will leverage our network of over 10,000 manufacturing partners to source the exact welding type needed for your project, complete with needed expertise, QA, and inspection services. Below is a general list of our main welding types, but note that each type of welding has sub-varieties that are not represented on this list. If you do not see the type of welding needed for your project below, reach out to us, and we will find the exact type needed for your project. 

Xometry’s welding services provide a vertical turnkey solution. Xometry will build the components and provide any necessary post-processing according to your technical needs.

Tungsten Inert Gas Welding

TIG welding is typically used for all-around projects or projects that require aesthetic welds, such as bike frames and vehicle manufacturing. TIG (short for Tungsten Inert Gas) welding is a process where a welding wire is held by the operator, and a torch supplies the arc needed for metal fusion. The wire feed is placed in the arc and melts into the joint, while an inert gas shields the weld from oxidation. 

Gas Metal Arc Welding

Gas metal arc welding (also known as GMAW, metal inert gas or metal active gas welding, or MIG & MAG for short) welding is a process where welding wire is fed via a nozzle to the joint, where an arc melts the wire and some of the base part’s surface. Either an inert (MIG) or an active (MAG) gas is supplied to shield the weld from oxidation and other defects. MIG welding is one of the most common welding types, and is commonly used throughout automotive production lines for its speed and ease of use.

Flux Cored Arc Welding

FCAW (short for flux core arc welding) is a welding process where a continuous wire-fed electrode and a constant-voltage welding power supply create an electric arc that fuses the base metal together. Flux-cored arc welding occurs with or without shielding gas and typically uses the same equipment used in MAG welding. The major difference is the use of a hollow or tubular electrode filled with a flux-cored wire, where once melted it forms the necessary shielding gas for the operation. Applications of FCAW welding applies to ferrous metals only, and is typically used to create heavy equipment and other uses where high deposition rates and weld penetration are required. 

Shielding Metal Arc Welding (SMAW, MMAW, or Stick)

Shielding metal arc welding (also known as SMAW; manual metal arc welding, or MMAW; or more simply arc or stick welding) is a process where the operator connects a welding rod to an electrode, and when the rod makes contact with the weld area an arc forms and melts the rod at point of contact. A flux surrounds the welding rod and covers the weld to prevent oxidation, which is removed post-weld. SMAW welding is the most common arc welding types available and is used for pressure vessels, tanks, exterior pipe welds, and a variety of other structural applications. 

Submerged-Arc Welding

SAW (short for submerged-arc welding) is an automatic welding process used to create long continuous welds. A powder flux is applied above the arc to both shield the weld and introduce various alloying elements into the weld pool. Typical applications of SAW welding include structural ferrous and non-ferrous projects, thick-walled designs, and high-strength joining operations. 

Spot Welding

Also known as resistance spot welding, or RSW for short, spot welding joins two pieces of metal together in a small point or “spot”. Two electrodes clamp down between the metals and an electrical current moves between them, causing the resistive metals to fuse. Spot welding is highly popular for its speed and its minimal heat-affected zones, being utilized by automotive manufacturers, fastener manufacturing, medical devices, and a vareity of consumer goods.

Asylon’s Autonomous DroneCore

Asylon, a drone infrastructure company, reached out to Xometry to get help manufacturing their DroneCore autonomous drone and base-station combination. Asylon drones autonomously fly from one base station, known as DroneHomes, to the next, recharging and dispensing the valuable data they picked up on their travels. Asylon needed Xometry’s help building the DroneHome station, specifically the weather-proof, stable sheet metal shell that houses the robotic arm and other necessary components needed for charging and data transfer. Xometry manufactured approximately 72" wide, 72” long, and 36” tall sheet metal assembly for the base station, implementing welding and joining operations to ensure the housing can resist precipitation and the harsh environment of the outdoors.
