How to weld magnesium plate with energy storage welding machine

Can magnesium be welded?

Magnesium can be welded, but it requires caution due to its high flammability. Be sure to clean the area after the welding process, as the resulting shavings can ignite. Tungsten inert gas welding is the best method for welding magnesium, as it produces strong welds.

How do you Weld magnesium?

Another option for welding magnesium is the laser beam welding (LBW) process. This process uses a high-powered laser beam to melt the metals together. Another common welding process for magnesium is plasma arc welding (PAW). PAW uses a plasma torch to create an arc between the electrode and the workpiece.

How to weld magnesium in TIG & MIG welding?

The first step in TIG welding magnesium is to clean the surface of the metal. This can be done with acetone or wire brush or sandpaper. Choose the right TIG filler wire based on the magnesium alloy type. TIG & MIG Welding filler wire for Welding Magnesium are classified in AWS A5.19 Specification.

Why does magnesium get distorted during welding?

Magnesium has a high coefficient of thermal expansion. So, unless precautions are taken, the metal tends to get distorted during welding. A proper weld sequence, intermittent welding, small bead size, and use of fixtures to arrest distortion are some of the steps that may be taken.

What filler metals can be used to weld magnesium alloys?

The four most commonly used filler metals to weld magnesium alloys are ER AZ61A, ER AZ101A, ER AZ92A, and ER EZ33A. You can buy these as MIG spooled wires if MIG welding, or as TIG welding rods for the TIG welding process.

Can You Weld a magnesium alloy if it gets too hot?

Magnesium alloys that are heat-treated to enhance strength are highly sensitive to high temperatures, and the strength of the material is affected when it gets too hot. After understanding the reasons to be extra cautious when welding magnesium, you should determine that the metal you want to weld is actually magnesium.
