A process for manufacturing a tie rod housing formed of a tie rod head (1) and a shaft element (2) fastened thereto. The tie rod head (1) receives its final shape by a mechanical machining process after the manufacture of the tie rod housing blank. The shaft element (2) and the tie rod head (1) are connected by means of a resistance pressure welding process. At least two material accumulations (8, 9), which connect the two components to one another, are brought about by a welding operation. The at least two material accumulations (8, 9) are subsequently created between the outer circumferential surface of the tie rod head (1) and of the shaft element (2).

What is claimed is: 1. A process for manufacturing a tie rod housing, the process comprising: providing a tie rod head blank and a shaft element blank; providing the tie rod head blank with a final tie rod head shape, having an outer circumferential surface, by a mechanical machining process after the manufacture of the tie rod housing blank; connecting said shaft element with said tie rod head by means of a resistance pressure welding operation to form a welded connection with a weld seam between said shaft element and said tie rod; forming at least two material accumulations as material in addition to said weld seam, at said shaft element and said tie rod by connecting said shaft element with said tie rod head by a subsequent welding operation to create said two material accumulations welded to each of said shaft element and said tie rod for forming an additional connection between said outer circumferential surface of the tie rod head and said shaft element. 2. A process in accordance with claim 1, wherein said material accumulations are arranged on diametrically opposite sides of said tie rod head and of said shaft element. 3. A process in accordance with claim 1, wherein said material accumulations are applied by means of a metal active gas (MAG) welding process. 4. A process in accordance with claim 1, wherein said material accumulations have essentially a triangular shape, wherein the limiting surfaces projecting over the base of the triangle, which faces the components to be connected, are sloped at an angle of about 45째 in relation to the base. 5. A process in accordance with claim 1, wherein said step of connecting said shaft element with said tie rod head by means of a resistance pressure welding operation produces a circular weld seam, said process further comprising removing, by means of a machining operation, said circular weld seam in partial areas that are arranged offset by approx. 90째 in relation to the material accumulations on the circumference of the shaft part. 6. A process in accordance with claim 5, the machining operation is a broaching operation. 7. A process in accordance with claim 1, wherein said shaft element of said tie rod housing is deformed by a bending operation after it has been finished. 8. A process in accordance with claim 1, wherein said shaft element of said tie rod housing is deformed by a bending operation. 9. A process in accordance with claim 1, wherein said two material accumulations are formed at spaced locations from each other. 10. A process in accordance with claim 9, wherein said weld seam is a circular weld seam formed by resistance pressure welding. 11. A process for manufacturing a tie rod housing, the process comprising: providing a tie rod head blank and a shaft element blank; providing the tie rod head blank with a final tie rod head shape, having an outer circumferential surface, by a mechanical machining process after the manufacture of the tie rod housing blank; connecting said shaft element with said tie rod head by means of a resistance pressure welding operation; forming at least two material accumulations connecting said shaft element with said tie rod head by a subsequent welding operation to create said two material accumulations between said outer circumferential surface of the tie rod head and said shaft element, wherein said material accumulations have essentially a triangular shape, wherein the limiting surfaces projecting over the base of the triangle, which faces the components to be connected, are sloped at an angle of about 45째 in relation to the base. 12. A process for manufacturing a tie rod housing, the process comprising: providing a tie rod head blank and a shaft element blank; providing the tie rod head blank with a final tie rod head shape, having an outer circumferential surface, by a mechanical machining process after the manufacture of the tie rod housing blank; connecting said shaft element with said tie rod head by means of a resistance pressure welding operation to produce a weld seam; forming at least two material accumulations, as material in addition to said weld seam, connecting said shaft element with said tie rod head by another welding operation subsequent to said resistance pressure welding operation to create said two material accumulations between said outer circumferential surface of the tie rod head and said shaft element. 13. A process in accordance with claim 12, wherein said step of connecting said shaft element with said tie rod head by means of a resistance pressure welding operation produces a circular weld seam and said process further comprises removing, by means of a machining operation, said circular weld seam in partial areas. 14. A process in accordance with claim 13, wherein said partial areas are arranged offset by approx. 90째 in relation to the material accumulations on the circumference of the shaft part. 15. A process in accordance with claim 12, wherein said material accumulations are applied by means of a metal active gas (MAG) welding process.
