(1) Install the two pieces of No. 4 engine liners on the No. 1 strut in accordance with the “strut welding combination” drawing, and place them on the clamp details, position the No. 1 strut by the stop pin and baffle plate, and clamp the No. 1 strut by the screw clamp; at the same time, position the two pieces of No. 4 engine liners by the bolt, and clamp them by the quick withdrawal screw clamp device;
(2) After tack welding, loosen the quick withdrawal screw clamping device, pull out the bolt and take it down for welding;
(3) Place the weldment on the clamp details, position the weldment by the stop pin and baffle plate, and clamp the weldment by the screw clamp; then place the components of NUT M6 and horn support on the weldment, and position the weldment by the screw clamp organization by the taper pin on the screw clamp organization and the open groove on the press plate of the screw clamp organization;
(4) Weld the assembly of NUT M6 and horn support and strut on three sides, and then loosen all screw clamps. The pressing plate of screw clamping organization of the assembly of clamping nut M6 and horn support is springed up by spring, and the locating cone pin on it gets rid of the weldment, then push out the pressing plate to get rid of the screw clamping organization stud at one end, turn the pressing plate to one side of the weldment, and then take out the weldment 。
