MIG TIG & SPOT Welding
At B&P, MIG TIG Welding is a crucial part of metal fabrication. We have a team of highly skilled MIG TIG welders utilising 25+ manual welding bays to produce assemblies of various sizes. Jigs and fixtures manufactured in our in-house tool-room are used to locate the parts and to ensure dimensional accuracy and repeatability. Where possible we will design the fixture to assist with error-proofing or poka yoke.
We also have 2 spot welding machines for use when weld visibility, or distortion needs to be kept to a minimum and 5 automated robotic welding bays for production of higher volume assemblies.
About the processes…
Metal Inert Gas Shielded (MIG) or Metal Arc Gas shielded (MAG) welding – an electric arc forms between a consumable wire electrode and the work-piece. The arc melts both the consumable filler wire and the parent metal, causing them to fuse together. A shielding gas protects the process from contaminants in the air. This process is predominantly used by B&P to weld mild steel in a thickness range of 0.9mm to 12mm.
Tungsten Inert Gas shielded (TIG) or Tungsten Arc Gas shielded (TAG) welding – a non-consumable tungsten electrode delivers the current to form an arc. The heat from the arc forms a weld pool of molten metal, a filler material is fed into the weld pool. The process is protected from the atmosphere and cooled with an inert gas, typically argon. This process is predominantly used by B&P for welding stainless steel in a thickness range of: 0.9mm to 3mm
Resistance spot welding is a process in which contacting metal surfaces are joined by the heat obtained from resistance to an electric current.
The process uses copper electrodes to concentrate welding current into a small “spot” and to simultaneously clamp the components together. Typically used on material in the 0.5 to 3 mm thickness range.
