Welding Capabilities

As specifications require, welding and fabrication processes can be performed manually or robotically. With our years of experience, we frequently create custom fixtures to ensure the highest accuracy of your weld. Our weld fitments are very precise and our fixtures often eliminate the need for machining operations.

Gas Metal Arc Welding (GMAW) Capabilities

Through a long working relationship with Miller Electric Company, AESI has developed high pressure welding procedures utilizing the GMAW processes currently performed in its fabrication facilities for commercial construction. Miller’s Regulated Metal Deposition (RMD) MIG welding process improves welding quality and productivity on carbon and stainless steel pipe. RMD is easy to learn and provides a simpler process that gets work done faster at a higher quality level, whether welding in-position or out-of-position.

  • Precisely controlled metal transfer provides uniform droplet deposition, making it easier for the welder to control the puddle
  • Easily bridges gaps up to 3/16-in. and creates more consistent root reinforcement on the inside of the pipe
  • RMD maintains a consistent arc length regardless of stick-out
  • The amount of the root pass metal deposited will be sufficient to supply the heat input requirements of the first Pulsed MIG or flux-cored fill pass, reducing the need for a TIG hot pass
  • Same wire and shielding gas can be used for the fill and cap passes using a next generation Pulsed MIG process called Pro-Pulse, which improves travel speeds and deposition rates while lowering heat input
  • Shielding gas comes out of the gun relatively undisturbed, pushing through the root opening and preventing sugaring on the back side of the weld. This allows certain 300 series stainless steel to be welded without a backing gas, which can improve productivity by as much as 400 percent

Gas Tungsten Arc Welding (GTAW) / TIG Welding

GTAW, also known as TIG welding, is commonly used where weld integrity is critical. Using the GTAW process, we are capable of producing high quality welds in a wide variety of metals and alloys.

Shielded Metal Arc Welding (SMAW) / Stick Welding

Commonly known as stick welding, SMAW is a manual process and one of the most versatile in the industry. This process can be used with many electrode types and sizes, in all positions and in a wide variety of materials.
