Hi,
I have an uncle who bought a tanning bed for his wife, when they trucked it home it was damaged during the trip. The part that was damaged was an arm extending from the stand, which would normally hold the lower half of the bed itself. The whole thing is pretty light, and the arm looks like a cast piece. The arm looks alot like aluminum, so I am thinking cast aluminum. I also thought it may also be magnesium, but shaving of the arm did not light on fire when i held a lighter to them. Now that the background has been laid out I have two questions
1. any suggestions of what the material may be other than cast alum, or magnesium, and if so how would i correctly identify the material?
2. what is a good process for welding cast aluminum?
If it is alum, I had planned pre heating to somewhere between 3 and 600 F for 30 min. then go on tiging this piece (4043) after making a very clean joint with a rotary file where the fracture is. After that I was going to throw it back on the hotplate for another 30 min.
Is there anything wrong with this procedure for alum? If it is another material what would be a good procedure for welding that?
