Abstract
Abstract A process for welding metal sections in which at least two metal workpieces are welded together across a contact area using corpuscular radiation beams to heat the metal in the respective workpieces adjacent said contact area and form a welded joint. A space is formed in the workpiece in the region of the contact area, the space being positioned within said area in a location in which the corpuscular radiation beams utilized for welding dissipate. A metal tube filled with a corpuscular radiation sink material is placed in said space. Said tube completely fills said space. Corpuscular radiation beams are directed from opposed sides of said joint to weld said workpieces together.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
116 words
A process for welding metal sections in which at least two metal workpieces are welded together across a contact area using corpuscular radiation beams to heat the metal in the respective workpieces adjacent said contact area and form a welded joint, comprising forming a space in the workpiece in the region of the contact area, the space being positioned within said area in a location in which the corpuscular radiation beams utilized for welding dissipate; placing a metal tube filled with a corpuscular radiation sink material into said space, said tube with said radiation sink material completely filling said space; and directing corpuscular radiation beams from opposed sides of said joint and welding said workpieces together.
Claim 2
Dependent Claim
116 words
A process for welding metal sections in which at least two metal workpieces are welded together across a contact area using corpuscular radiation beams to heat the metal in the respective workpieces adjacent said contact area and form a welded joint, comprising forming a space in the workpiece in the region of the contact area, the space being positioned within said area in a location in which the corpuscular radiation beams utilized for welding dissipate; placing a metal tube filled with a corpuscular radiation sink material into said space, said tube with said radiation sink material completely filling said space; and directing corpuscular radiation beams from opposed sides of said joint and welding said workpieces together.
Claim 3
Dependent Claim
62 words
The process of claim 1, wherein said space is formed by forming a rounded elongated groove in the contact area of each of said workpieces, said grooves being positioned opposite each other when said workpieces are positioned to be welded to form said welded joint, and locating said tube in said groove; and wherein said corpuscular radiation is a beam of electrons.
Claim 4
Dependent Claim
18 words
Method according to claim 1, wherein said metal tube is filled with radiation sink material in powder form.
Claim 5
Dependent Claim
21 words
Method according to claim 1 wherein said radiation sink material comprises lead, lead alloys and pulverous silicates mixed with iron powder.
