HVT’s Welding Services

Formerly United Welders, High Velocity Technologies continues to service Western Australia with a 70-year, multi-generational welding legacy.

As welding and material specialists, HVT is experienced in welding the suite of low, medium and high-carbon steels, steel alloys, stainless steel, high-chromium alloys and non-ferrous materials, such as copper, bronze, aluminium, magnesium, and all types of cast irons (i.e. nodular/spherical/ductile, grey, white and malleable cast irons).

What’s On Offer?

At High Velocity Technologies, our specialised welding services are fully-equipped to satisfy your welding needs, be it a simple joining task, complex cracking, heat treatment or complete rebuild repairs.

A selection of the welding operations we perform are:

  • Forge Welding – Undertaken at exceptionally high temperatures (up to 1000°C), forge welding forces metals together either using heat to achieve a molten state and facilitate joining, or both heat and kinetic energy (i.e. hammering or other high pressures) to induce plastic deformation at the join. Requiring highly-skilled, professional welders and specialised equipment, forge welding’s labour-intensive methodologies produce homogenous joints that will last the distance.
  • Internal and External Orbital (ID/OD) Welding – ID welding and OD welding are used extensively to repair cracking or rebuild worn parts on internal and external bores and tubing. Also known as orbital welding, the welding torch is rotated in a circular motion around the workpiece using MIG or TIG welding processes.

 

  • Metal Arc Welding (MAW) – Also referred to as manual metal arc welding (MMAW), electricity is used to create an arc to reduce the metals to a molten state. A sheathed filler wire is then applied, and the melting electrode forms shielding gas to prevent oxidation during the solidification process. MAW welding is a highly flexible and versatile technique that can be used on a variety of different metals and thicknesses.
  • Tungsten Inert Gas (TIG) Welding – Electricity is used to create an arc between a tungsten electrode and the base metal, producing a weld pool to facilitate the addition of the filler material. Shielding gas is used during the welding process to produce an oxygen-free environment and prevent oxidation as the weld solidifies. TIG welding results in contaminant-free, high-quality welds, though it can be a more labour-intensive and skilled operation than other welding techniques. It is also a highly flexible, versatile technique that can be used on a variety of different metals and thicknesses.
  • Metal Inert Gas (MIG) welding – An arc and continuously-fed wire electrode is moved through the welding gun into a weld pool to join two metals. Shielding gas is also used to create a contaminant- and oxygen-free environment to produce high-quality welds. A flexible process, MIG welding is suitable for a wide variety of metal types and thicknesses.
