Pipe Welding Techniques For Various Purposes

Aluminum fabrication Brisbane involves pipe welding techniques that are an essential part of any industrial construction project. Welding is basically a simple and easy way to join pipes and elongate for various purposes. Pipe welders use a variety of pipe welding techniques to ensure a safe construction. This is very important because when used by large scale projects, there can be hazardous materials that might be carried by these pipes. Precision and accuracy of pipe welding becomes the prime concern of welders for this type of usage. This is why only certified and trained professionals must be hired to carry out pipe welding jobs.There are a number of techniques to do it based on the need and quality. Major types include MIG Welding, Arc Welding and TIG welding.MIG Welding Technique. -Aluminum 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. Although both DC and AC are useable, DC is recommended to be avoided due to elevated heat generation on the tungsten electrode. 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. -Advantages of TIG welding technique over other methods are: -=> 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 handle using the appropriate tools and expertise so that optimum results can be achieved for pipe fabrication. For this reason, TIG welding, although an expensive option, is preferred by many certified welding companies over the other techniques used in pipe welding.
