What is the difference between 4043 and 5356 aluminum?
As a basic description we can say that 4043 is an aluminum filler alloy with 5% silicon added and that 5356 is an aluminum filler alloy with 5% magnesium added. However, there are many common structural aluminum base alloys that can be welded with either 4043 or 5356. One such alloy is 6061.
What setting do you use to weld aluminum?
For welding thick materials, a low AC frequency of 80 to 120 Hz is typically well-suited for materials 3⁄8 in. and thicker and will help you to achieve a wider weld bead profile. Proper heat input is a critical factor in successfully welding aluminum with GTAW.
How many amps do you need to weld 1/4 aluminum?
When you know those, you can easily determine how many amps you will need for your welder to weld aluminum perfectly. A common rule of thumb is that you will need 1 amp for every 0.001 inches of metal you are going to weld when other variables are constant.
What is 5356 aluminum wire used for?
alloys
Alloy 5356 is an all position non-heat treatable TIG wire used to weld the 5XXX series alloys when 40,000 psi tensile strength is not a requirement.
What does ER4043 stand for?
ER4043 (commonly referred to as ALSi-5) is a 5% Silicon Aluminum filler metal that is used primarily for welding Aluminum Alloys 3003, 3004, 5052, 6061, 6063 and Casting Alloys 43, 355, 356, and 214.
Do you weld aluminum with AC or DC?
DC is used for TIG welding Mild Steel/Stainless material and AC would be used for welding Aluminium. The TIG welding process has three options of welding current based upon the type of connection. Each method of connection has both advantages and disadvantages.
What polarity do you weld aluminum?
Use the Correct Polarity That’s why it’s crucial you use alternating current (AC) polarity when TIG welding aluminum. This polarity provides a cleaning action that helps remove and break up the oxide layer on aluminum, creating a nice flowing weld puddle.
CAN 6061-T6 aluminum be welded?
There are many aluminum base materials that can be welded successfully with any number of different filler alloys. The base alloy referenced in the above question, 6061-T6 for instance, is commonly welded with at least four totally different filler alloys and can be welded successfully with even more.
How thick will a 180 amp welder weld?
A 180-amp unit can weld between 3/8” and 5/16” steel. A 200-amp unit can weld between 5/16” steel. A 250-amp unit can weld 1/2” steel.
How thick can a 225 amp welder weld?
Powerful welder But the Lincoln AC 225, starts where others fail. It can easily weld through 16 gauge and above. That makes it a very powerful welding machine suitable for heavyweight construction work.
Which is the best wire for MIG welding aluminum?
5356 is probably the most widely Aluminum wire used. Although it is more difficult to weld with, however it is a stronger wire than 4043. It is a better all purpose Aluminum wire. It is generally used for welding boats because it is good with salt water. It is used for 5000 series Aluminum.
What kind of aluminum does a welder use?
As a home hobby welder there are a few types of Aluminum Alloy you are likely to come across – the 4000 series alloys, 5000 series and 6000 series alloys. In these alloys Aluminum is of course the main element typically over 90% of the alloy.
When did alcotec start making aluminum welding wire?

Which is the best filler metal for a MIG welder?
4043 and 5356 are the two most commonly used Aluminum filler metals in a MIG welder. 4043 is a general purpose Aluminum welding wire. The addition of silicon makes welding easier as it is more forgiving to the person welding.
