Abstract

A broadhead including parts inseparably connected by laser welding.

1 . A broadhead comprising: 
 a plurality of parts, wherein at least two of the parts are permanently fastened together at a laser welded seam.    
   
   
       2 . The broadhead of  claim 1  wherein the parts comprise at least one blade.  
   
   
       3 . The broadhead of  claim 1  wherein the parts comprise a cap.  
   
   
       4 . The broadhead of  claim 1  wherein the parts comprise a collar.  
   
   
       5 . The broadhead of  claim 1  wherein the parts comprise a ferrule.  
   
   
       6 . The broadhead of  claim 1  wherein the parts comprise a tip structure.  
   
   
       7 . The broadhead of  claim 1  wherein no flux or other filler material has been added to the seam.  
   
   
       8 . The broadhead of  claim 1  wherein flux or other filler material has been added to the seam.  
   
   
       9 . The broadhead of  claim 1  wherein the laser welded seam comprises a spot welded seam.  
   
   
       10 . The broadhead of  claim 1  wherein the laser welded seam comprises overlapping spot welds.  
   
   
       11 . A broadhead comprising: 
 a plurality of blades;    wherein at least one of the blades is permanently joined to another part of the broadhead by a laser welded seam.    
   
   
       12 . The broadhead of  claim 11 , wherein the other part is another blade.  
   
   
       13 . The broadhead of  claim 11  wherein the other part is a cap or collar.  
   
   
       14 . The broadhead of  claim 11  wherein the other part is a ferrule.  
   
   
       15 . A broadhead comprising: 
 a first blade;    at least one other part, wherein the at least one other part is selected from the group consisting of a second blade, a cap, a collar, and a ferrule;    wherein the blade and the other part are permanently fastened together at a laser welded seam that contains no flux or filler material.
