Abstract

Disclosed in this description is a means for welding materials together by shooting a projectile partially therethrough.

Claims

1. A method for welding material together comprised of shooting a projectile partially through the material at a velocity such that said projectile and said material form a weld.

2. The method of claim 1 wherein said projectile is of the same material as said material.

3. The method of claim 1 wherein said projectile is shot perpendicular to said material.

4. A device for welding material by shooting a projectile partially through said material, said device being comprised of:

impact means;

stopping means, wherein said projectile is impacted by said impact means and thereby shot partially through said material to abut against said stopping means.

5. The device of claim 4 wherein said stopping means is mobile enough to absorb the impact of said projectile.

6. The device of claim 5 further comprising holding means for holding the material to be welded against said stopping means.

7. The device of claim 4 wherein said stopping means has a surface shape which causes said projectile to flatten thereagainst thus forming a flattened end on one side of said welding material, said impacter having a shape causing the opposing side of said projectile to form a flattened end on a side opposing said one side of said welding material, such that the weld formed by said projectile and said material is flattened at opposing ends and against said material.

8. The device of claim 4 wherein there is a plurality of impact means, stopping means, and projectiles such that a plurality of welds may be formed at one time.

9. A device for welding material by shooting a projectile partially through said material, said device being comprised of:

impact means; and

stopping means, wherein said projectile is impacted by said impact means and thereby shot partially through said material to abut against said stopping means, and wherein said projectile has a rounded or pointed tip extending from (atop) a generally cylindrical body, said tip being located opposite said impact means such that when said projectile is shot by said impact means said tip will abut against said stopping means.

10. The projectile of claim 9 wherein said body has an indentation around its diameter.

11. An article of manufacture having weld formed between metals, said weld being comprised of a projectile that is flattened at both ends against said metals to assist in holding said metals together.

12. The article of claim 11 wherein said metals and said projectile are comprised of the same material.
