Abstract
1,087,506. Welding by fusion. CHICAGO BRIDGE & IRON CO. Feb. 25, 1966 [April 8, 1965], No. 8475/66. Heading B3R. [Also in Division G1] In an arc welding apparatus having a welding head which moves upon a track and carries the welding torch, a photo-cell is mounted upon the head and controls the movement of the head in accordance with the intensity of light received from the arc and pool of molten metal. As shown in Fig. 3, a water-cooled shoe 27 retains the molten weld metal 13 in a vertical joint and passes light from the weld area through a hole 40 on to a photo-sensitive resistor 30. The intensity of light received depends upon the distance of the hole 40 from the surface of the molten weld metal and the object of the control is to match the movement of the head to the rate of deposit of weld metal. In one arrangement the head is moved in stages at constant speed, the movement starting when the level of molten metal rises to cause a predetermined light intensity to fall on the resistor 30. In another arrangement the head movement is continuous and the speed varied in accordance with the photo-cell output. The light falling on the photo-cell may be adjusted by the valve 36 shown or one of a number of various diameter rings placed in the light passage (Figs. 5 and 6, not shown) or an iris diaphragm. Carbon dioxide or argon is pumped into the light passage to the photo-cell to maintain the hole 40 clear and provide an inert atmosphere at the weld area. The apparatus may exclude the shoe and may be horizontal.
