Welding Aluminized Sheet Metal

But first a word about safety before you start welding make sure the area is well ventilated.

It may take some practice so here are some tips for welding aluminium. How to weld aluminium to steel aluminum is a relatively soft thin lightweight metal while steel is much tougher heavier and thicker so joining the two can be very difficult. Since the aluminum is a coating on steel sheet metal there is the possibility that the aluminum will begin to wear over time.

There are two easy methods for welding aluminum to steel although both require more time and work than ordinary welding. Aluminized steel is used in the manufacture of automotive exhaust parts and other items due to its heat and corrosion resistance. The oxide layer on the edge prevented the two sheets from mixing and has left a crack in the weld. For a corrosion resistant completed weld use one of the 400 series stainless steel wires.

Spot welding must first consider the position of the workpiece welding and consider positioning tools in mass production to ensure an accurate spot welding position. To weld sheet metal with solid wires use electrode positive ep or reverse polarity. Tig welding sheet metal. Sheet metal welding has argon arc welding laser welding spot welding carbon dioxide protection welding stainless steel sheet welding aluminium sheet welding manual arc welding etc.

Welding aluminium is just different from welding steel. The weld to the left is the reverse side of an aluminium weld where the edge of the metal was not cleaned before welding. Often when welding steel and stainless steel to an aluminium alloy an interlayer of pure aluminium is used which drastically reduces intermetallic formation. Aluminium is often thought to be hard to weld however that s not entirely true.

Intermetallic compounds between friction welded steels and aluminium alloys are iron aluminium based consequently it would be expected that the brittle compounds would also be formed between the steel and pure aluminium but this is. You can weld aluminized tubing with gas metal arc welding gmaw using er70 s6 mild steel filler metal and 75 percent argon 25 percent oxygen shielding gas but this will leave the finished weld zone unprotected because the aluminum will be burned away. Forget the larger 1 8 inch tungsten electrode and use a smaller one. Since 15 years aluminized steel type 1 plate suppliers in india in various sizes finishes all india metal corporation is finding for more stockholders in middle east europe.
