A method for manufacturing a bulb bar, bulb bar and manufactured according to the method.

摘要

The present invention concerns a method for manufacturing a valve and also BAR BAR valve produced by the method. BULB BAR IS MADE IN ACCORDANCE WITH THE FOLLOWING STEPS: SEPARATELY flatten a portion of the bar (2); SEPARATELY flatten a portion of the bar FLAT (3); WELDING AND PART OF BULB (2) A PART OF FLAT BAR (3). PART OF THE BULB (2) is flattened WITH A WAY WITHOUT BORDERS TO ALLOW PART Wegde (3) whose dimensions have been selected PROPERLY IN ACCORDANCE WITH BAR BULB (1) with a torsional stiffness REQUIRED TO BE wELDED TO THE bORDER REGION longitudinally extending (8.9) PART OF BULB AND ALLOW heat generated during WELDING PROCESS DRIVEN TO BE PART OF THE BULB. THE BORDER REGION ABOVE INCLUDES angled surfaces (8,9) forming in each case a support region extending longitudinally and a contact region and also PREPARATION FOR UNION SUBSEQUENT a welding process.
