The invention discloses a process for producing an enclosed 
halogen tungsten automobile headlight, which comprises the following steps: (1) carrying out 
racking; (2) carrying out buttwelding, namely melting and butting two ends of a 
copper pin and a 
molybdenum pin through power supplying to form a 
copper-
molybdenum pin; (3) carrying out 
spot welding of 
molybdenum plates, namely respectively performing 
spot welding between the one end of each of three molybdenum plates and each of three molybdenum rods on a light stand, and between the other ends of the three molybdenum plates and three 
copper-molybdenum pins; (4) after completing the manufacture of a wick and a glass 
bulb, carrying out press seal, and reserving an air exhaust rod at the upper end of the glass 
bulb; (5) performing 
hydrogen brightening and air exhausting, namely completing the 
hydrogen brightening and air exhausting on a round exhaust 
machine together; (6) bending the copper-molybdenum pins after stable power-on burn-in detection; and (7) after completing manufacturing a lamp base, carrying out focusing 
assembly, carrying out surface covering, displacing gas in an inner cavity of the 
halogen tungsten automobile headlight, carrying out 
leak detection process, and carrying out finished production inspection after the 
leak detection process. The process can reduce 
rejection rate, has simple and convenient operation and high work efficiency.
