Welding Methods

Various welding methods presented by Dyna Torque Technologies Inc.

The cutting-edge welding equipment of Dyna Torque Technologies Inc. are compatible for a number of welding methods, including fully mechanized welding equipment, and manual and automated (hybrid systems).

Welding Methods

  • Automated or mechanized welding – Root to Cap

J-bevel (Narrow Groove Closed Root with backing); J-bevel (Narrow Groove Closed Root without bcking); and V-bevel (Factory bevel Open Root)

  • Manual/Automated

Hybrid (Factory bevel – Manual root (SMAW) with automated Fill and Cap)

  • Bevel Fit-up

Open Root and Closed Root with Backing

Welding Processes


Our FCAW welding system is compatible with Flux-cored arc welding (FCAW or FCA), which, based on the needs, either is a semi-automatic or automatic arc welding process. With FCAW, a consumable tubular electrode containing a flux is continuously fed. More commonly, a constant-voltage power is supplied to the electrode; however, in some cases, a constant-current welding power is required.


Gas metal arc welding (GMAW) that often is referred to as metal inert gas (MIG) and metal active gas (MAG)—actually, a subtype of GMAW—is a distinct welding process, which offers contamination-free welding. The welding process draws its name from an electric arc formed between the work-piece metal and the consumable wire electrode; the arc heats and melts the metal resulting into a welding joint. We have a range of mechanized welding systems, as well as manual models, that are compatible with GMAW. Our GMAW welding system, embedded with microprocessor, is designed with the aim to cut welding time and produce error-free welding without need of a expert operator.


A subset of GMAW, MIG welding includes a shielding gas, fed through the welding gun, which offers protection from the contamination during the pipe welding procedure and other fabrication processes. Our variety of flexible GMAW welding system supports MIG welding as well and thus helps contractors to cut cost of operations.

Our multitude of mechanized welding and manual models show compatibility with different welding positions, including

  • 1G
  • 1G – rotation
  • 2G
  • 5G
  • 6G

In line with the demands of pipe welding procedure, the array of our FCAW welding system and GMAW welding systems have proven their worth in different field conditions.
