Aluminium is my FAVOURITE metal to weld with the TIG or Tungsten Inert Gas process. Although I love it now, at first it was difficult for me to control the weld puddle and even lay down something that looked like a weld. Below I’ll give you 5 quick tips that should help you weld Aluminum.<\/p>\n

Quick Aluminum Welding Tips<\/u><\/strong><\/h3>\n

– Understand Your Metal<\/strong><\/p>\n

– Copper Wire Brush<\/strong><\/p>\n

– Clean, Clean, Clean<\/strong><\/p>\n

– Torch Angle is Key<\/strong><\/p>\n

– Practice<\/strong><\/p>\n

1. Understand Your Metal<\/h3>\n

Aluminium has high thermal conductivity properties which means the heat is going to want to spread throughout the material. Unlike steel, when TIG welding on aluminium, keep in mind your travel speed can be faster.
\nAluminium is a porous metal with a melting point of 1,221 F.
\nAluminium is the most abundant metal on earth but does not occur as a metallic form in nature, instead it\u2019s an ore known as Bauxite.<\/p>\n

2. Wire Brush<\/h3>\n

Wire Brush material with copper or brass wire brush. This will help break up and remove the oxide layer (do not use a steel wire brush as the steel will contaminate the aluminium).
\nCopper Wire Brushes work great to break up the oxide layer.
\nWhen brushing your aluminium you will notice the metal starts to dull. This is a good sign that you have broken up some of the oxide layers.
\nKeep in mind that I have also had good results with one direction brushing as opposed to forward and backward brushing, so give this a go.<\/p>\n

3. Clean Metal<\/h3>\n

Wipe down base material and filler rod with denatured alcohol or acetone. Aluminium is extremely sensitive to impurities, so clean your filler rods even if they are brand new.
\nSetting up is crucial for proper aluminium welds – be sure your machine settings such as  gas flow, cup sizes etc. are correct for your application.
\nIf you are working on a steel surface while welding aluminium, it’s important to have a clean and smooth table without any metal shavings. Metal shavings can arc your aluminium and cause burnt marks.<\/p>\n

4.Torch Angle Is Key<\/h3>\n

Torch angle is important because your filer rod will want to ball up before you can even dip so make sure you feed your aluminium filler rod fast. Also, be sure your TIG welding torch angle remains 90 degrees or as close to vertical as possible.
\nCertain applications will allow for a slight tilt in your welding torch angle but it\u2019s never much for aluminium.<\/p>\n

5.Practice!<\/h3>\n

As obvious as this sounds it can’t be more true. I got good at welding aluminium by getting a production welding job that required 80% Aluminum TIG welding. I’m constantly tweaking with frequency, cleaning action, cups, tungsten and new techniques. One technique I found very helpful when welding aluminium is to watch the puddle, not your tungsten!<\/p>\n

This all may seem overwhelming at first but my recommendation to you is to change one thing at a time, take some deep breaths of fresh air when you get frustrated, and just keep welding!<\/p>\n

\"TIG<\/p>\n

Now your knowledge is up to speed, make sure your welding machine is too! We have a large range of new and used or refurbished AC\/DC TIG welding machines for aluminium welding applications, take a look at our current stock here<\/a> or alternatively if you are thinking about selling your machine, speak to Peter and Bev<\/a> for a fair and easy deal!<\/p>\n","protected":false},"excerpt":{"rendered":"
