Opting For The Right Pipe Welding Techniques

If you think welding is about gunning the machine and wait till it the metal is jointed, think again. Welding is considered as one of the highly sophisticated processes that involve more techniques and dynamics than most of the other manufacturing work. Welding is not always carried out at highly conducible environment under industrial roof; it might be required in deep sea or aerospace. Approximately all the man-made stuff used is a direct or indirect output of welding equipments, whether it is about industrial aluminium fabrication Brisbane or domestic appliance maintenance.

Numerous methods are available to get it done as per desired need and quality. Major types include MIG Welding, Arc Welding and TIG welding.

MIG Welding Technique.

Aluminium alloy wire is employed in MIG (Metal Inert Gas) or GMAW (Gas Metal Arc Welding) as a pooled electrode and filler. The filler metal is required to be supplemented periodically therefore welding without filler-material is not possible. As all welding factors are controlled by the welding machine, this process is also termed as semi-automatic welding technique.

Arc Welding Technique.

The concentrated heat of an electric arc to join metal is utilized in Arc Welding technique. This happens when the parent metal fuses with the additive metal. Additive metal is extracted by a consumable electrode. Both DC and AC are useable in this technique.

TIG Welding Technique.

Permanent non-melting electrode made of tungsten is employed in TIG welding (Tungsten Inert Gas). It could be done with or without filler material as per need. DC is a not a preferred choice in order to avoid elevated heat generated levels but bith AC and DC can be used. In variation of TIG-welding, Argon as a shielding gas is used. It is multipurpose process as it offers the user great flexibility for range of thicknesses. AC TIG-welding is possible with thicknesses down to about 0.5 mm to larger than 5 mm of metal thickness.

Advantages of TIG welding.

TIG welding technique is preferred over other techniques for the following reasons:

=> Versatility to be compatible for most material

=> Feasibility for all geometrical shapes

=> Superior quality

=> No smolder or fumes

=> No vitreous mass left as a residue by smelting

The process of welding needs to handled using the appropriate tools and expertise so that optimum results can be achieved for pipe fabrication Brisbane. For this reason, TIG welding, although an expensive option, is preferred by many certified welding companies over the other techniques used in pipe welding.
