A note on Aluminum welding:

Thursday, November 11th, 2010

Welding aluminum can be done either with a wire feed welder or stick machine. All the general welding safety rules apply, and follow them can avoid dangerous accidents.

• Wear protective welding hood while welding aluminum. UV rays can be very harmful to eyes.

• Always wear welding gloves, long jeans, boots and welding jackets so that welders can protect their body from sparks and heat caused by welding.

• Always route the welding leads and cables from the welder to the steel so that nobody can trip on them.

• Always turn the welder off and put cords and leads safely away after welding aluminum. Clean up any tools and materials used in the project so they don’t become a hazard.

• Before inspecting the machine make sure that all the cords and welding leads are free of defects and that no bare wire is showing before welding aluminum.

A View On Aluminum Welding:

Monday, October 25th, 2010

Welding of aluminum can turn out to be as a tricky task and it is usually saved for professionals. To learn the process and proper techniques of weld by following safety precautions it will usually take lot of your time. After learning the process of aluminum welding you can conduct this activity on your own.

While performing the task of aluminum welding you must check the surroundings of your work environment. Be away from electrical wires or outlets and keep your environment well ventilated. In addition to this one important point you must remember is, to perform the task by wearing gloves, welding helmet and by following other safety measures too. Do remember that your head should always be away from any fumes, even when you have worn a weld helmet.

Clean the aluminum that you are going to weld. Spray off the surface of aluminum with the help of electrical cleaner and then rinse it off with clean water. Dry up the metal once the dirt is clear. At the time of aluminum welding remember that this is the area where you are going to compress the pieces so as to prevent them from wrapping.

How to protect yourself while welding Aluminum:

Friday, October 22nd, 2010

You can weld aluminum either with the help of wire feed welder or a stick machine. If you don’t follow safety rules it can lead to dangerous accidents.

• Always wear a protective welding hood when aluminum welding. Ultra violet rays created in welding process are very harmful to the eyes.

• While welding it is important that you wear thick leather welding gloves, long jeans, boots and a welding jacket to protect yourself against sparks and heat caused by welding.

• Clean the work area if there are any flammable items such as rags.

• Inspect the machine to ensure that all the cords and welding leads are free of defects and that no bare wire is showing before welding aluminum.

• Always turn the welder off and put the cords and leads safely away after welding aluminum. Clean up any tools and materials used in the project so they don’t become a hazard.

Aluminum Welding: Tips For A Good Weld

Wednesday, October 21st, 2009

The most complicated alloy is aluminum. The metal is with good grace accessible in the market. They are available in various forms of product. Firstly aluminum oxide ought to be removed from the surface of the metal. Aluminum welding is difficult to perform. The main issue with aluminum is that it gets heated up real quickly. The metal’s melting point is very low. Therefore certain measure ought to be taken to make aluminum welding easy. Here are a few essential tips to achieve this;

  • Preheat it with the help of a blowtorch. This curtails distortion.
  • TIG welder can be very expensive. Go in for MIG welding if you run short of money.
  • The most appealing feature of the metal is that it has low density. It is terrific
    conductor electricity.
  • Utilize a heat sink as the metal picks up heat swiftly.
  • Keep an eye on the metal slides. They have got to be tight as one while you
    weld.

Aluminum Welding

Monday, June 22nd, 2009

Some of the factors that affect the welding of aluminum are

  • Aluminum Oxide coating
  • Thermal conductivity
  • Thermal expansion Coefficient
  • Low melting temperature

Melting point of Aluminum oxide is nearly 1926 ° C. As the aluminum oxide film becomes thicker, it will start absorbing moisture from the air. Moisture is a source of hydrogen which is the cause of porosity in aluminum welds. Hydrogen can come from oil, paint, dirt, base metal, oxide, etc. Hydrogen will enter the weld pool and is soluble in molten aluminum. Hydrogen is rejected during solidification. Prior to welding, aluminum oxide film must be removed. If not, it may lead to reduction in ductility, lack of fusion and weld cracking.

Aluminum has a thermal conductivity which is about six times as fast as steel, which means more heat has to be put into aluminum even when the melting point is less than half that of steel.

Four Tips For The Aluminum Welder

Friday, May 15th, 2009

When you are an aluminum welder, you must take extra precautions because this metal is thin and soft to work with. It is easy to experience burn through, which is when the heat from your torch is so hot that it will burn a hole through the work material. Your equipment and accessories should help you to create a better weld or the manufactured good you desire.

Tip one: Every aluminum welder should keep their torch at a angle from the source material. You must be sure that you don’t put it too close or you will experience burn back. You may destroy your material if your weld isn’t controlled and uniformly done. A badly welded piece will look straggly and unequal. But if done properly the welder should produce a great looking finish.

Tip Two: Clean pieces of aluminum are required when you are doing any aluminum welding. Be sure that you clean the aluminum of any oxides before you actually weld. You can clean the aluminum with a brush that should be used only for cleaning any aluminum metals. The oxides are need to be cleaned from the work material by an stainless steel brush.
