We operate a dedicated welding and fabrication section equipped with Mig, Tig and arc welding facilities. Much of the CNC laser cutting and metal forming work we undertake has a combined element of welding and fabrication.
We also have 2kw spot welding facilities with a range of interchangable nodes.
Our highly skilled welders are fully skilled at reading welding diagrams and schematics from technical drawings as well as pocessing the skill and experience to carry out quality, clean strong welds repeatably.
All types of weld joints can be undertaken including
- butt joint welding
- lap joint welding
- edge joint welding
- T-joint welding
- corner joint welding
- double-V preparation joints
- Single-U and double-U preparation joints
- make multipass welds
Weld types offered include:
- Forward Welding
- Backward Welding
- Fillet Welding
- 304 Stainless Steel Welding
- Thin Gauge Sheetmetal Welding
- Invisible Welding
We offer high quality Gas Tungsten Arc Welding (GTAW), TIG welding, predominantly for aluminium using an Argon with either Hydrogen or Helium sheilding gases.
We offer high quality Gas Metal Arc Welding (GMAW), MIG welding, which offers a mauch faster deposition rate in comparison to TIG welding using an Argon with either Oxygen, CO2 or Helium sheilding gases. Our welders are fully experienced with all primary transfer modes including Spray transfer, Globular transfer and Short circuiting transfer.
Stainless Steel is a moderatly difficult material to weld. The primary consideration for stainless steel welding is distortion, and in many cases full jigging must be set up beforehand. Other considerations include the threat of localized corrosive attack due to welding and is one of the concerns when selecting base metal, filler metal and welding procedures. Another issue is cracking which can occur in various regions of the weld with different orientations, such as centerline cracks, transverse cracks, and microcracks in the underlying weld metal or adjacent heat-affected zone.Â These cracks are primarily due to low-melting liquid phases which allow boundaries to separate under the thermal and shrinkage stresses created during the weld solidification and cooling. The solution to this is a consitently hot weld area.
We can weld most ferritic, martensitic, austenitic, and duplex materials although some stainless steels such as magnetic and precipitation-hardening stainless steels.
Aluminium is generally the most difficult alloy to weld and requires a thorough understanding of the alloy to hand be it a heat treatable or a nonheat treatable alloy. Our welders are skilled at working with the following aluminium alloys:
- 1xxx: Unalloyed (pure) >99% Al
- 2xxx: Copper is the principal alloying element, though other elements (Magnesium) may be specified
- 3xxx: Manganese is the principal alloying element
- 4xxx: Silicon is the principal alloying element
- 5xxx: Magnesium is the principal alloying element
- 6xxx: Magnesium and Silicon are principal alloying elements
- 7xxx: Zinc is the principal alloying element, but other elements such as Copper, Magnesium, Chromium, and Zirconium may be specified
