Onsite welding will advise you on the best method of welding to satisfy your needs. Give us a call today for any TIG, MIG or Stick welding requirements, we'd be glad to help.

TIG welding is suited to joining of lighter gauge materials with section thicknesses from about 0.8 to 12.5mm. It is also suited to the joining of pipes, ducting and intricate welds. Joints can be butts, lap welds, edge welds and fillets.

MIG
welding allows for a high current density with deep penetration and welding speeds higher than for TIG. This means less total heat input and less chance of distortion. The process of TIG and MIG welding automatically removes the oxide layer electronically.

During the positive cycle of AC current, aluminium oxide particles are stripped from the weld pool allowing the fusion of oxide free metal in the next cycle.

Some pre-cleaning of the joint for welding is still required to ensure the weld is completely free of oxide.
