	I am working in a fasteners manufacturing plant. We want to produce a new product, a weld bolt. It is an unthreaded bolt made of st44-2 steel with a small aliminium ball embedded in its tip. The question is; how are we going to embedd this aliminium ball in a harder steel? Are there ready made machines doing such a process? what is the technical name of the process, so that I can search by using that name as a keyword. Thanks

	A hole is formed in the tip, ball inserted and the tip swagged to retain the ball. The depth of the hole is larger than the radius of the ball. How can it be a bolt without threads? __________________ Mr.Ron from South Ms.

	Nice one ronseto. Swaged (swaging), crimped (crimping), flaring, staking, and spinning or whirling are all other possible methods, depending on design. milo __________________ People say between two opposed opinions the truth lies in the middle.

	Hello MILO, @ Ron Years ago when I was into reloading my own ammunition I had equipment the sized cast bullets by forcing it through a die. I also had a piece of equipment that forced lead wire into a pre sized mold that was shaped like a bullet. This was considered a swaged bullet. I considered this bullet to be inferior to the cast bullets as the softer material was lead fowling the gun barrel, the cast bullets were a blend of lead, tin, and antimony and thus a little harder. As to the original post, I am not aware that a bolt needs threads, ie, bolts in guns, etc.. however the bolt represented by the poster apparently has a ball shaped cavity in the end and the softer aluminum could be forced into the end filling that space. However, I am totally unsure just why anyone would want to do this. TMF __________________ The only problem with common sense, is that not very many people have it, or know how or when to use it.

	That bolt is used in the construction of the bridges. It is welded on a frame at the point of the aliminium ball. The aliminium fuses and makes a connection.
